Server Quality Checklist

Profile completionA complete profile improves this server's visibility in search results.

Latest release: v2.6.12
Disambiguation2/5
With 253 tools, there is significant overlap in functionality (e.g., multiple quote tools, numerous financial statement variants). Although descriptions are detailed, the sheer volume makes it difficult for an agent to reliably select the correct tool without confusion.
Naming Consistency3/5
Most tools follow a 'get' + noun pattern, but there are inconsistencies like 'stockScreener' (camelCase) and 'listCommodities' (verb 'list' instead of 'get'). While the pattern is mostly predictable, these deviations lower consistency.
Tool Count1/5
253 tools is excessively high for a single MCP server. It overwhelms both the agent and the user, making it impractical to navigate. A more focused scope or hierarchical grouping would be necessary.
Completeness5/5
The server covers an extremely broad range of financial data: quotes, financial statements, ratios, technical indicators, insider trading, SEC filings, ETFs, mutual funds, forex, crypto, commodities, and more. There are very few obvious gaps in its coverage.
Average 3.5/5 across 253 of 253 tools scored. Lowest: 2.3/5.

How is the quality score calculated?

The overall quality score combines two components: Tool Definition Quality (70%) and Server Coherence (30%).

Tool Definition Quality measures how well each tool describes itself to AI agents. Every tool is scored 1–5 across six dimensions: Purpose Clarity (25%), Usage Guidelines (20%), Behavioral Transparency (20%), Parameter Semantics (15%), Conciseness & Structure (10%), and Contextual Completeness (10%). The server-level definition quality score is calculated as 60% mean TDQS + 40% minimum TDQS, so a single poorly described tool pulls the score down.

Server Coherence evaluates how well the tools work together as a set, scoring four dimensions equally: Disambiguation (can agents tell tools apart?), Naming Consistency, Tool Count Appropriateness, and Completeness (are there gaps in the tool surface?).

Tiers are derived from the overall score: A (≥3.5), B (≥3.0), C (≥2.0), D (≥1.0), F (<1.0). B and above is considered passing.

Tool Scores

Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description does not add significant behavioral context beyond the annotations (readOnlyHint, idempotentHint, openWorldHint). It fails to disclose what the tool returns or any side effects, relying solely on the annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences but is wordy and not front-loaded with the core action. It prioritizes marketing language over succinct functionality, though it is not excessively long.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema, the description should explain what the tool returns. While it mentions ESG scores and controversies, it does not clearly state the output format or how the data is structured, leaving significant gaps for the agent.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema already describes the 'symbol' parameter as 'Stock symbol' with 100% coverage. The description does not add any additional meaning or constraints beyond what the schema provides, so baseline score of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose2/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description is vague and uses marketing language ('Align your investments with your values') instead of clearly stating that the tool returns ESG disclosures for a given stock symbol. It does not differentiate from sibling tools like getESGRatings or getESGBenchmarks.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives. There is no mention of when not to use it or which sibling tools serve different purposes.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Description adds no behavioral info beyond annotations. Annotations already indicate read-only and idempotent, but the description does not address pagination, rate limits, or data freshness.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, efficient but second sentence is generic fluff. Could be slightly tighter.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With no output schema and many sibling tools for filings and disclosures, the description fails to clarify the specific role of this tool. Incomplete for the complexity.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% but the description mentions 'filing dates' which are not reflected in parameters. Creates confusion; does not compensate for the mismatch.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose3/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description states it retrieves detailed disclosures for mutual funds and ETFs based on filing dates, but lacks specificity on how dates are used or returned. Does not differentiate from sibling tools like getFundDisclosure or getForm13FFilingDates.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool vs alternatives. No exclusions or context for appropriate usage.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, covering safety. The description adds context about SEC filings and compliance, but no behavioral details beyond that (e.g., error handling, output format). Neither contradictory nor highly informative.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, front-loaded with the core action. No redundant words, though the second sentence is somewhat generic. Efficient overall.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema exists, and the description does not clarify what the tool returns (e.g., company details, confirmation). This leaves a significant gap for a search/retrieval tool, especially with many sibling tools.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with clear descriptions for both parameters. The description does not add significant meaning beyond what the schema already provides, so baseline of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose2/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description states it retrieves a CIK, but the required parameter is 'cik' itself, making it unclear what the tool actually does (lookup? validation?). It does not differentiate from siblings like 'searchCompaniesByCIK' or 'getCIKList', which likely perform similar functions.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives. Given the many related sibling tools (e.g., searchCompaniesByCIK, getCIKList), the absence of usage context is a significant gap.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already set readOnlyHint, idempotentHint, and openWorldHint. The description adds generic behavioral context (operating/investing/financing activities) but does not contradict annotations. It does not provide additional details like data freshness or pagination.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise (two sentences) but is generic and marketing-oriented. It lacks front-loaded critical details such as 'TTM' and the nature of the returned data.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the lack of output schema and the presence of many sibling tools, the description is incomplete. It does not specify the return structure, the TTM time frame, or how it differs from other cash flow endpoints.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Input schema has 100% coverage with descriptions for both parameters (symbol and limit). The description does not add any further meaning about the parameters, so baseline score of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose3/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description mentions cash flow activities and categories (operations, investments, financing) but lacks specificity about returning TTM data. It does not clearly distinguish from siblings like getCashFlowStatement or getCashFlowStatementGrowth.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives such as getCashFlowStatement or getCashFlowStatementBulk. The description offers no usage context or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, openWorldHint. The description adds that reports are as filed with the SEC, but does not disclose any other behavioral traits like response format or error handling.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, concise with no extraneous content. However, the first sentence could be more direct without the product name repetition.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Despite high schema coverage, the description is misleading by focusing only on annual reports while the tool supports quarterly periods. No output schema or examples are provided, leaving the agent uncertain about the data structure.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so parameters are adequately described in the schema. The description adds no additional meaning beyond the schema's definitions.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose3/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description states it provides annual reports (10-K), but the input schema includes quarterly periods (Q1-Q4), creating ambiguity. It does not differentiate from sibling tools like getBalanceSheetStatement or getIncomeStatement, which also provide financial data.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives such as getBalanceSheetStatement, getIncomeStatement, or getFinancialReportXLSX. The description lacks context for selection.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate readOnlyHint true and idempotentHint true, so the safety profile is clear. However, the description adds no extra behavioral details (e.g., what dates are returned, error handling, or output format).
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, but the first is slightly promotional and could be trimmed. The description is reasonably concise but not maximally efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple single-parameter tool, the description lacks specificity about what 'financial reports dates' includes (e.g., earnings dates, filing dates). Given many sibling tools with similar themes, more context is needed.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema already covers the single 'symbol' parameter with a description. The tool description adds no further meaning, so baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('access') and resource ('latest financial reports dates'). However, it includes a vague clause about tracking metrics that doesn't match the tool's actual purpose.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives like getEarningsCalendar or getEarningsReportsDates. The description lacks decision context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate readOnlyHint=true and idempotentHint=true, so the description adds minimal behavioral context beyond stating it runs an analysis. No contradiction with annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences with no extraneous words. However, structure is flat; could be improved with bullet points or clearer separation of purpose and usage.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema exists, but the description does not mention return values or typical results. Given the complexity of DCF analysis with many parameters, the description is incomplete for an agent to understand the full behavior.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, the description fails to explain any of the 19 parameters. It only vaguely mentions 'detailed inputs', providing no added meaning beyond what the schema already provides.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
Clearly states it runs a tailored DCF analysis using the FMP API. The verb 'run' and resource 'DCF analysis' are specific, and the name distinguishes it from sibling tools like calculateCustomLeveredDCF, though no explicit differentiation is provided.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives such as getDCFValuation or calculateCustomLeveredDCF. The description does not mention prerequisites or context, leaving the agent to infer usage.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and openWorldHint. The description adds no behavioral details beyond 'detailed' – no mention of pagination, rate limits, or return format. This adds minimal value for an agent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, clear and concise. Slightly marketing-flavored ('gain insights') but not excessively verbose. Effective for a quick read.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema exists, yet the description fails to explain what the returned balance sheet contains (e.g., fields like total assets, liabilities items). Sibling tools are not distinguished. The description is incomplete for full usability.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
All three parameters have descriptions in the input schema (100% coverage). The description does not add any new meaning or usage hints beyond the schema, meeting the baseline expectation.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it accesses balance sheet statements, specifying assets, liabilities, and equity. However, it does not differentiate from sibling tools like getBalanceSheetStatementAsReported or getBalanceSheetStatementGrowth, which share the same resource.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool vs. siblings such as getBalanceSheetStatementGrowth or TTM variants. The description omits context about typical use cases or alternatives among the many similar tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, and openWorldHint=true, which cover safety and idempotency. The description adds 'real-time' and 'current' but does not elaborate on data freshness, rate limits, or other behavioral traits beyond what annotations provide.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence that efficiently conveys purpose and scope. It is appropriately concise and front-loaded, though it could be slightly more precise about the output scope.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has one parameter, annotations, and no output schema, the description adequately explains the purpose and general output (prices, changes, volume). However, it lacks details on the exact fields returned, which would help the agent understand the response structure.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema coverage is 100% for the single required parameter 'symbol', with a clear example 'BTCUSD'. The description does not add any additional parameter semantics or format guidance beyond the schema, so it meets the baseline for high coverage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'access' and resource 'real-time cryptocurrency quotes' and specifies it provides a 'concise overview' of prices, changes, and trading volume. It distinguishes itself from sibling tools like getCryptocurrencyQuote by indicating a shorter/simpler output, but does not explicitly differentiate.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives such as getCryptocurrencyQuote, getCryptoQuotes, or getCryptocurrencyBatchQuotes. No prerequisites or exclusions are mentioned, leaving the agent without context for selection.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and openWorldHint, covering safety. The description adds no behavioral details beyond 'comprehensive calendar', failing to disclose traits like data latency, filtering behavior, or any constraints.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences with minimal fluff. It front-loads the purpose but contains marketing language ('Stay informed', 'make informed decisions') that could be trimmed for directness.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With only two optional parameters and no output schema, the description covers the basic data retrieval function. However, it lacks details on response format, pagination, or how 'upcoming' is defined, leaving gaps for an agent.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with both parameters documented (from_date and to). The description uses 'calendar' to imply date range, but does not add meaning beyond the schema's basic format descriptions.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool accesses a calendar of economic data releases, using specific verbs 'stay informed' and 'access'. It distinguishes from siblings by specifying 'Economic Data Releases', but does not explicitly differentiate from similar calendar tools like getEarningsCalendar or getIPOCalendar.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no explicit guidance on when to use this tool versus alternatives. It only mentions a general goal ('prepare for market impacts') without specifying context or conditions that would trigger its use.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, and openWorldHint=true. The description does not add any behavioral details beyond the annotations, such as pagination behavior, default sorting, or date range assumptions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences are concise, but the first sentence ('Stay informed...') is somewhat promotional and does not add functional value. The second sentence provides the core functionality. Could be trimmed but overall efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given three optional parameters and no output schema, the description lacks details about return structure, sorting, or how 'latest' is defined. It does not differentiate from siblings, leaving gaps for an AI agent to fully understand the tool's scope.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema itself documents all parameters. The description does not add extra meaning beyond the schema, such as explaining how page and limit interact or that cik filters results. Baseline of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description states it tracks new shares being issued and provides insights into exempt offerings and amendments, which clearly indicates the purpose. It distinguishes from siblings like getEquityOfferingsByCIK and searchEquityOfferings by focusing on 'latest' offerings without filtering, but does not explicitly contrast.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus related siblings such as getEquityOfferingsByCIK or searchEquityOfferings. The description only implies general use for staying informed, without specifying contexts or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations indicate read-only and idempotent, but description adds no behavioral detail. The claim 'any given date' contradicts schema (no date param), potentially misleading.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, front-loaded with verb and resource, no wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

The description adds minimal behavioral context beyond 'access' and does not disclose data freshness, rate limits, or potential result variations. With annotations covering safety, the description fails to add significant value.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description consists of two concise sentences that convey the tool's purpose and use case without extraneous information. It is well-structured and front-loaded.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description mentions 'specific dates' but the input schema has no parameters to specify dates, creating confusion. Additionally, there is no output schema, and the description does not explain what the tool returns or how the market risk premium is presented (e.g., a single value, series, etc.). This completeness gap is significant given the contradiction between description and schema.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The tool has no parameters, and the schema coverage is 100% (empty). Per the calibration guide, 0 parameters scores a baseline of 4. The description does not need to add parameter info since none exist.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool accesses the market risk premium for specific dates using the FMP API. It provides context on the metric's financial relevance. While the name itself is descriptive, the description reinforces the purpose without explicitly differentiating from siblings, but the unique metric name suffices.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description mentions 'use this key financial metric to assess additional return expected,' but it does not provide guidance on when to use this tool versus alternatives, nor does it indicate when not to use it. There is no exclusion criteria or comparison with sibling tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already provide safety traits (readOnlyHint, idempotentHint, openWorldHint). Description adds minor API source detail but no behavioral context like data freshness, response structure, or rate limits.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two concise sentences with no redundancy. Each sentence adds value, though minimal.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema. Description is vague about return data ('detailed data', 'key information'). Users cannot infer exact output format or fields, which is needed for a no-param tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
No parameters, schema coverage 100%. Description does not need to elaborate on parameters, and no additional semantic value is required.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool accesses detailed data on the S&P 500 index and tracks constituent companies. It distinguishes from siblings like getDowJonesConstituents by explicitly naming the index.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives (e.g., getDowJonesConstituents). Does not specify ideal scenarios or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and openWorldHint, covering safety and idempotency. The description adds minimal context beyond 'search' behavior, but does not discuss potential rate limiting, pagination details, or response structure, so it does not significantly enhance transparency beyond annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences, front-loading the main purpose. It is concise but could be slightly improved by removing the redundant mention of 'FMP Search Press Releases API'.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema, the description should explain return values or format. It only says 'Find specific corporate announcements and updates', which is vague. The pagination parameters (page, limit) are not contextualized in the description. Still, annotations provide a good safety profile.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 100% description coverage, so parameters are already documented. The description mentions 'company name' but the required parameter is 'symbols', which is a comma-separated list of stock symbols; this mismatch may mislead the agent into thinking company names are accepted.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool searches for press releases using a stock symbol or company name. However, it does not explicitly differentiate from the sibling tool 'getPressReleases', which likely has a different purpose (e.g., listing all press releases without search).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives like 'getPressReleases' or other search tools. The description does not mention when not to use it or any prerequisites.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already provide readOnlyHint=true, idempotentHint=true, and openWorldHint=true. The description adds 'personalized and precise valuation', which is not a behavioral trait. It does not contradict annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, no fluff. Could be slightly more precise but is efficiently structured and front-loaded with the core action.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given many parameters and no output schema, the description should explain what the tool returns (e.g., DCF value, assumptions summary). It omits completely, relying on user inference. Incomplete for a complex financial tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has descriptions for all parameters (though context says 0% coverage, which may be an error). The description adds no additional meaning beyond the schema, so baseline score of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it runs a tailored DCF analysis using the FMP Custom DCF Advanced API, with fine-tuning of assumptions. However, it does not differentiate from the sibling 'calculateCustomDCF' (likely basic vs levered), which is important for selection.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool vs. alternatives (e.g., 'calculateCustomDCF'). No context on prerequisites, scenarios, or exclusions. The description lacks any usage context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate read-only and idempotent behavior. The description adds only that it uses the FMP ADX API and historical price data, which is already implied. No additional disclosure about potential errors, data freshness, or edge cases. Minimal value added beyond annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise, consisting of two sentences that efficiently state purpose and benefit. No superfluous words or redundant information. It is front-loaded with the core action.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description lacks information about the output format or return value. Given the absence of an output schema, the tool would benefit from describing what the API returns (e.g., a JSON object with ADX values). The parameter documentation is complete, but the overall picture is incomplete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
All five parameters have descriptions in the input schema (100% coverage), so the schema already documents their meaning. The description does not add any additional context or constraints beyond the schema, earning a baseline score of 3.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool calculates ADX for a stock, specifying the resource and action. It mentions 'analyze trend strength and direction' which adds context. However, it does not explicitly differentiate from sibling technical indicator tools like getRSI or getSMA, which would strengthen clarity.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description gives a general use case ('analyze trend strength and direction') but provides no guidance on when to use this tool versus alternatives, nor any prerequisites or limitations. No explicit 'when not to use' or comparison with siblings.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and openWorldHint, covering safety and repetitiveness. The description adds context about measuring growth over time, but does not detail response structure or data interpretation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two concise sentences that front-load the purpose. No unnecessary words, but the second sentence adds minimal value beyond the first.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema is provided, and the description fails to explain what the growth rate looks like (e.g., percentage, absolute change, or the format of returned data). This is a significant gap for a tool with only high-level context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with all parameters described. The description provides no additional parameter details beyond the schema, so baseline score of 3 is appropriate.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already provide readOnlyHint, idempotentHint, and openWorldHint, indicating a safe read operation. The description adds minimal behavioral context beyond being a bulk API, so it meets the baseline but does not exceed it.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description consists of two concise sentences: first stating the purpose, second the target audience. It is efficient and front-loaded, though not exceptional.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool claims to retrieve data for multiple symbols, but the input schema only includes 'date'—no symbols parameter. The description does not clarify how symbols are specified, leaving a significant gap. Additionally, no return value details are given, though no output schema exists.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema fully describes the sole parameter 'date' with format YYYY-MM-DD, providing 100% coverage. The description adds no additional meaning, meeting the baseline of 3 for high coverage.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description says it is 'ideal for financial analysts, traders, and investors who need to assess valuations for a large number of companies,' implying bulk use but not when to prefer over single-symbol tools. No exclusions or alternatives are mentioned.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate read-only, idempotent, and open-world behavior. The description adds that it offers 'hourly intraday data' and a 'detailed view of trends,' but does not disclose limitations like data availability, pagination, or response structure. No contradiction with annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?

Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise with two sentences, front-loaded with the action. The second sentence is slightly redundant but overall efficient and free of fluff.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema exists, and the description does not explain what the search results contain (e.g., fields, structure). The agent lacks context about the response format, which is crucial for a search tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The parameter 'company' is fully described in the schema (100% coverage) as 'Company name or partial name'. The description merely reiterates this without adding new semantic details like case sensitivity or wildcards.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it searches for SEC filings by company name, distinguishing it from sibling tools like searchCompaniesByCIK and searchCompaniesBySymbol. However, it does not differentiate from the generic 'searchName' tool, which may cause ambiguity.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use this tool versus alternatives, nor any mention of when not to use it. The description only states what it does without providing decision criteria.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and openWorldHint, so the description adds minimal behavioral context beyond a generic statement about analyzing financial position changes. It does not disclose rate limits, pagination, or data format.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence that is reasonably concise and front-loaded with the tool's purpose. However, it could be more tightly worded by removing the phrase 'allows users to'.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the absence of an output schema and the tool's 'bulk' nature, the description should explain what data is returned (e.g., growth metrics for all companies or a list). The current description is insufficient for an agent to fully understand the tool's behavior.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with descriptions for both parameters (year and period). The description adds no additional parameter-specific meaning, so baseline score applies.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool retrieves growth data across multiple companies' balance sheets, distinguishing it from single-company alternatives. However, it does not explain how companies are specified (e.g., all companies or a subset), leaving ambiguity in the 'bulk' scope.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus siblings like getBalanceSheetStatementGrowth (singular) or getBalanceSheetStatementsBulk (bulk statements). The description lacks any context for tool selection.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, openWorldHint. The description adds that data comes 'directly from official filings', which confirms the source. No additional behavioral details like pagination, rate limits, or response size are provided, but the description does not contradict annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, no extraneous information. The first sentence is slightly redundant ('As Reported Balance Statements API' mirrors the tool name), but overall efficient and front-loaded with the key purpose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description explains the return content (balance sheet items from filings) but doesn't address how parameters like limit and period affect the output or mention response format. For a simple tool with no output schema and adequate annotations, this is minimally complete but lacks guidance for effective use.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so baseline is 3. The description mentions 'assets, liabilities, and equity', adding context about the return data but not about the parameters themselves. No additional parameter semantics beyond what the schema provides.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it provides balance sheets 'as reported by the company' from official filings, differentiating from standardized or growth variants among siblings. The verb 'access' combined with specific resource makes the purpose clear, though it doesn't explicitly contrast with similar tools.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus the many balance sheet alternatives (e.g., getBalanceSheetStatement, getBalanceSheetStatementGrowth). No mention of prerequisites or exclusion criteria, leaving the agent to infer context from the tool name alone.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, and openWorldHint=true. The description adds no new behavioral traits (e.g., data freshness, rate limits) beyond confirming it's a data access tool. Thus, it does not enhance transparency beyond the annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, with purpose front-loaded. However, the first sentence includes promotional phrasing ('with the Balance Sheet Data API') that is unnecessary and could be trimmed for conciseness.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema, so return structure is undocumented. The description omits clarification of 'TTM' (trailing twelve months) and how 'limit' affects results. For a simple tool, it is adequate but not fully complete given sibling differentiation needs.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with descriptions for both 'symbol' and 'limit'. The description does not add any additional meaning or context for these parameters beyond what the schema already provides. Baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool provides balance sheet statements for publicly traded companies, with a verb 'access' and resource 'balance sheet statements'. However, it does not differentiate from sibling tools like getBalanceSheetStatement (non-TTM) or getBalanceSheetStatementGrowth, missing the 'TTM' nuance in the name.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives (e.g., getBalanceSheetStatement or getBalanceSheetStatementGrowth). The description lacks any mention of suitable contexts, prerequisites, or scenarios where this tool is preferred.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, openWorldHint, covering safety. The description adds standard cash flow reporting details (operating, investing, financing) but fails to explain critical behavior: how 'bulk' works with only year/period parameters (no ticker). This omission reduces transparency to baseline.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences, front-loaded with the verb and resource, and contains no redundant or vague phrasing. Every sentence adds value.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity of a bulk tool with no ticker parameter, the description should explain what 'bulk' means (e.g., returns data for all companies or requires a symbol elsewhere). It also lacks output format details, and the absence of output schema increases the need for description completeness. The description is insufficient.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Input schema has 100% description coverage for both year and period, so the schema itself adequately explains them. The description adds no additional meaning, such as expected formats or constraints. Baseline of 3 is appropriate given high schema coverage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description states it provides 'access to detailed cash flow reports' and 'retrieve bulk cash flow statement data,' clearly identifying the resource and bulk nature. However, it doesn't clarify that the input schema lacks a ticker parameter, leaving ambiguity about whether data is for all companies or a set. Sibling tools like getCashFlowStatement likely require a ticker, so the distinction is partially clear but not fully.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives such as getCashFlowStatement, getCashFlowStatementGrowth, or other bulk tools. The description is generic and does not mention use cases or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, and openWorldHint=true. The description adds no new behavioral context beyond labeling it a 'comprehensive database'. With annotations covering the safety profile, a score of 3 is appropriate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description contains two sentences: one stating the purpose and one touting importance. It is fairly concise, but the second sentence is somewhat marketing-heavy and could be omitted or condensed without loss of functional information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (one optional parameter, no output schema), the description provides the core purpose. However, it does not mention output format, authentication requirements, or how it differs from similar sibling tools like 'searchCIK'. This leaves some gaps but is minimally adequate.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so the parameter 'limit' is fully documented in the schema. The description does not add any additional meaning or context about the parameter, resulting in a baseline score of 3.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool provides CIK numbers for SEC-registered entities. The verb 'access' is vague, but the context of a database lookup is clear. However, it does not distinguish from the sibling tool 'searchCIK', which likely serves a similar purpose with filtering.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description mentions it is 'essential' for those needing CIK numbers but provides no guidance on when to use this tool versus alternatives like 'searchCIK'. There are no explicit conditions, exclusions, or comparisons to siblings.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint and idempotentHint, so the safety profile is clear. The description adds that it uses the FMP SEC Company Full Profile API, but does not disclose further behavioral traits such as data freshness or pagination. With annotations covering the key aspects, a score of 3 is appropriate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence with the verb 'Retrieve' at the beginning, making it concise and front-loaded. It includes key data categories without extraneous information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool provides detailed company profiles including multiple data types, but the description does not specify the output structure or guarantee completeness. Without an output schema, more detail about return format would help. Overall, it is adequate but not fully comprehensive.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with descriptions for both parameters ('Stock symbol' and 'Central Index Key'). The description does not add any additional meaning beyond the schema, so baseline 3 is suitable.

Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool accesses real-time quotes for multiple forex pairs simultaneously. It uses specific verbs and resources, and the 'Batch' prefix distinguishes it from single-quote tools like getForexQuote. However, it does not explicitly differentiate from sibling getForexQuotes (which might also be batch), so purpose is clear but not fully distinctive.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives, such as getForexQuote for a single pair or getForexShortQuote for short quotes. There is no mention of prerequisites, limitations, or exclusions, leaving the agent without strategic direction.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate read-only and idempotent behavior. The description adds output details (headlines, snippets, URLs) but does not explain pagination, date filtering, or source ambiguity.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, no fluff. First sentence states purpose, second describes output. However, 'Stay updated' is slightly indirect; could be more action-oriented.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Covers purpose and output type but lacks details on pagination, date ranges, and order. No output schema to compensate. Adequate but not fully complete for a 4-param tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

The description adds context beyond annotations by listing specific data contents (public offering prices, SEC links). However, it does not disclose pagination, date range boundaries, or data freshness. Annotations already declare readOnlyHint=true, idempotentHint=true, openWorldHint=true, which the description does not contradict.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is three sentences with no redundant content. It front-loads the purpose and includes specific examples and value-add (SEC links). Could be slightly tighter but is efficient overall.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the simple parameter set (2 optional dates) and no output schema, the description covers the data source and types. However, it lacks details like output format, behavior when dates are omitted, and whether the response is paginated. It is adequate but leaves gaps.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema covers 100% of parameters with descriptions ('Start date (YYYY-MM-DD)' and 'End date (YYYY-MM-DD)'). The description doesn't add any extra meaning beyond the schema, so the baseline score of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description specifies the resource ('IPO prospectuses') and key data points (public offering prices, discounts, etc.), making the purpose clear. However, it uses the vague verb 'Access' instead of a more precise action like 'List' or 'Retrieve'.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives (e.g., getIPOCalendar, getIPODisclosures). It neither states when to use nor when not to use, leaving the agent without decision context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, openWorldHint. Description adds 'latest' and 'real-time view' but no details on pagination or result volatility. Does not contradict annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, reasonably concise. Slight fluff from 'Stay up to date with' but overall efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Low complexity with 2 params and no output schema. Description is adequate but could specify what data is returned (e.g., list of filings with holder, date, form type).
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with descriptions for page and limit. Description adds no parameter information; baseline 3 applies.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it retrieves latest SEC filings related to institutional ownership. However, it does not differentiate from similar filing tools like getFilingsBySymbol or getLatest8KFilings.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives like getFilingsByFormType or getLatestFinancialFilings. Lacks when-not or explicit context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate read-only, idempotent, and open-world nature. The description adds no behavioral details beyond 'comprehensive overview' and 'quickly retrieve,' without disclosing potential size limits, data freshness, or response structure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences with clear purpose and target audience. No redundant phrases, efficiently communicates the tool's value.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given zero parameters, output schema absent, and annotations present, the description is minimally adequate. It lacks details on timeframe options, response structure, or handling of large datasets, but remains functional for its simplicity.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
No parameters; schema coverage is 100% by default. The description adds context that it covers 'all listed symbols,' which is baseline-appropriate. A score of 4 is suitable as no parameter information is needed.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states it provides 'comprehensive overview of price targets for all listed symbols over multiple timeframes,' which distinguishes it from single-symbol siblings like getPriceTargetSummary. However, it doesn't explicitly contrast with other bulk or summary tools.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives like getPriceTargetSummary or getPriceTargetConsensus. The description implies it's for bulk retrieval but doesn't specify when to choose this over others.

Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and openWorldHint. The description adds no additional behavioral details beyond stating the tool analyzes financial ratios, which is consistent with annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is brief and front-loaded, stating the purpose clearly. However, it redundantly repeats 'Financial Ratios API' and could be slightly more concise without losing clarity.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description explains the tool provides ratios for operational and financial health, but with no output schema, it lacks detail on return structure or specific ratio types. For a tool used for detailed analysis, this is somewhat incomplete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
All three parameters (symbol, limit, period) are fully described in the input schema (100% coverage). The description does not add new meaning or usage hints beyond what the schema provides.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states the tool provides financial ratios for a company's performance, including profitability, liquidity, and efficiency metrics. However, it does not differentiate itself from numerous sibling tools like getKeyMetrics or getFinancialScores.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is given on when to use this tool versus alternatives, such as getKeyMetricsTTM or getRatiosTTMBulk. The description implies general analysis but lacks specific use cases or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already provide readOnlyHint, idempotentHint, and openWorldHint. Description adds that it calculates RSI based on historical price data, but does not elaborate on data freshness, rate limits, or authentication aspects. Adequate given annotation coverage, but adds minimal extra value.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two concise sentences that front-load the essential information: what the tool does, the API used, and its purpose. No superfluous words or repetition. Every sentence earns its place.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given 5 parameters, no output schema, and numerous sibling tools, the description is incomplete. It does not describe the return structure (e.g., array of date-RSI pairs), limitations, or how the output can be used. The agent lacks critical information to effectively invoke and utilize the tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Input schema has 100% description coverage, with each parameter clearly described (symbol, periodLength, timeframe, from_date, to). Description does not add further meaning, such as typical values for periodLength (e.g., 14) or date format details. Baseline score of 3 is appropriate since schema already does the heavy lifting.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
Clearly states the tool calculates RSI for a stock, using the FMP API, and explains its purpose for momentum analysis and overbought/oversold conditions. Name and description are specific to RSI, distinguishing it from generic indicator tools, but lacks explicit differentiation from similar indicators like SMA or EMA.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives. Does not mention prerequisites, typical use cases (e.g., identifying overbought/oversold), or when to choose RSI over other momentum indicators. The agent receives no context for decision-making.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, and openWorldHint=true, indicating a safe read operation. The description adds context about the data content (trade dates, assets, amounts) but no additional behavioral traits beyond what annotations provide.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence that is clear and front-loaded, but it could be slightly more concise by removing the introductory clause 'Monitor the trading activity of US Senators with the FMP Senate Trading Activity API.' It is efficient overall.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple tool with one parameter and no output schema, the description is adequate but could be more complete by specifying date ranges, limits, or how results are ordered. It also doesn't clarify that only trades for a given symbol are returned.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 100% coverage for the single parameter 'symbol', so the schema adequately explains it. The description mentions data fields but does not add meaning to the parameter beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool monitors Senate trading activity, listing data types included. However, it does not differentiate from sibling tools like getSenateTradesByName or getLatestSenateDisclosures, which could lead to confusion about which tool to use for specific queries.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives. The description only states what it does, not when to prefer it over siblings that might offer filtered results or different scopes.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate readOnly, idempotent, and openWorld hints. The description adds context about real-time updates and news links, which is helpful but not critical behavioral disclosure beyond annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences are concise and front-loaded with purpose. The second sentence is slightly long but contains relevant details. No wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the simple 3-parameter schema and rich annotations, the description adequately covers the tool's output (grades, news links, stock prices) and usage context. Missing explicit pagination info but acceptable.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
All three parameters (symbol, page, limit) have descriptions in the schema (100% coverage). The description does not add significant new meaning beyond confirming usage for specific symbols, so baseline score of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool provides real-time analyst grade changes with details like grading company, previous/new grades, and action. It distinguishes itself from siblings like getStockGrades and getStockGradeSummary by emphasizing real-time updates and news links, but doesn't explicitly differentiate.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for staying informed on analyst grade changes for specific symbols, but no explicit when-to-use, when-not-to-use, or alternatives provided. Lacks guidance on choosing this over sibling tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate read-only and idempotent behavior. The description adds context about real-time tracking and monitoring over time periods, but does not disclose limitations like supported symbols, data freshness, or what happens for invalid symbols. With strong annotations, the added value is moderate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences, front-loaded with the action verb 'Track'. It is concise but the second sentence slightly repeats the first. Overall efficient, but could be trimmed.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema, the description hints at response contents (percentage and value changes over periods). For a simple one-parameter tool, this provides adequate context, though it could specify whether it returns a single value or multiple periods.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Input schema has 100% coverage for the single required 'symbol' parameter with a basic description. The description does not add extra meaning about symbol format, case sensitivity, or examples. As schema coverage is high, baseline of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool tracks stock price changes (percentage and value) over various time periods, using a specific verb 'Track' and naming the FMP API. However, it does not contrast with sibling tools like getQuote or getIntradayChart, leaving some ambiguity about when to use this specific tool.

Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate readOnlyHint, idempotentHint, and openWorldHint. The description adds that the data is 'real-time', which is somewhat at odds with idempotency (though not contradictory). It does not clarify data freshness, rate limits, or response size. Since annotations cover the safety profile, the description adds minimal extra behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two concise sentences: the first states the core purpose, the second adds context. Every word earns its place; no redundancy or filler.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given a simple schema (one optional bool), no output schema, and good annotations, the description is mostly adequate. However, it does not mention the 'short' parameter or hint at the structure of the return value. For a tool with no output schema, this omission reduces completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema is fully described (100% coverage) with a single optional boolean 'short' parameter with a schema description. However, the tool description does not mention this parameter or explain its effect. At baseline 3, the description adds no further semantic value beyond what the schema already provides.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it provides real-time quotes for stock indexes and allows multiple indexes in one request. However, it does not distinguish itself from sibling tools like getIndexQuotes (which may also return multiple indexes). The word 'All' in the name suggests a broad scope, but the description fails to specify what 'all' entails compared to getIndexQuotes.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives. It does not mention scenarios, prerequisites, or when not to use it. Given the presence of siblings like getIndexQuote (single index) and getIndexQuotes, the lack of usage guidance is a notable gap.

Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise with two sentences. The first sentence clearly states the purpose, and the second adds value by mentioning analysis use cases. No redundant or extraneous content.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With no output schema, the description should describe the return data structure to aid model expectations. It mentions price data, trends, and volumes but does not specify fields (e.g., open, high, low, close, volume). Given the parameter simplicity, completeness is moderate.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
All three parameters (symbol, from_date, to) have descriptions in the input schema (100% coverage). The description does not add further meaning beyond what the schema already provides, so a baseline of 3 is appropriate.

Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate read-only and idempotent behavior. The description adds that it uses historical price data and helps generate signals, which provides some context but does not cover rate limits, error handling, or data sources beyond what is implicit.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two concise sentences that front-load the action and purpose. No unnecessary words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description is minimal but covers the basic function. Given the presence of many sibling indicators, more differentiation would help, but it is not critically incomplete. No output schema exists, so return value explanation is optional.

Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool calculates DEMA for a stock and mentions its use for trend analysis and buy/sell signals. It differentiates from siblings by naming the specific indicator (DEMA), but does not explicitly contrast with similar tools like getEMA or getSMA.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use DEMA vs alternatives such as EMA, SMA, or TEMA. There are no usage scenarios, exclusions, or prerequisites mentioned.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and openWorldHint. Description adds minor context about using the FMP API but no additional behavioral traits like rate limits or data freshness.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, front-loaded with core action, second sentence adds usage context. No unnecessary words or redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Missing description of output (e.g., returns dates and EMA values). Does not mention that the tool requires valid stock symbols or potential API limitations. Adequate but not complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
All 5 parameters have descriptions in the input schema (100% coverage). The tool description does not add new meaning beyond what schema provides, so baseline score of 3 applies.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states it calculates EMA for a stock, with specific verb 'Calculate' and resource identified. However, it does not distinguish from sibling tools like getSMA or getDEMA, so lacks differentiation.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use this tool vs alternatives. It mentions trend analysis and signals but does not provide context on when EMA is preferred over SMA or other indicators.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, and openWorldHint=true, indicating safe, repeatable reads with potentially varying results. The description does not contradict these but adds no extra behavioral context (e.g., data freshness, rate limits).
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences long, front-loading the purpose. The first sentence states the action, the second adds context about use cases. Slightly verbose with marketing language ('make informed and responsible investment decisions'), but overall efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With no output schema, the description should explain what the tool returns. It does not describe output format, example values, or how the optional 'year' parameter affects results. Missing crucial details for agent decision-making.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with one optional parameter 'year', described in the schema. The description does not add any meaning beyond the schema, so baseline score 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool evaluates and compares ESG performance of companies and funds, using specific verbs ('evaluate', 'compare') and resource ('ESG benchmarks'). It distinguishes itself from similar ESG tools like getESGRatings and getESGDisclosures.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?

The description adds that the tool returns headlines, snippets, and URLs, but does not disclose any behavioral traits beyond what annotations provide. With high annotation coverage, the description's contribution is marginal.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is comprised of two concise sentences that are front-loaded with action and resource. Every word adds value without redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description lists output elements but lacks details on pagination, ordering, or result structure. Given the tool has page and limit parameters, this information is important for a complete understanding.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema already documents both parameters (page, limit). The description does not add any additional meaning or context for these parameters.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool accesses 'latest articles from Financial Modeling Prep' and lists output elements (headlines, snippets, URLs). However, it does not explicitly differentiate from sibling news tools like getGeneralNews or getStockNews, which may cause confusion.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives. Given many similar news-related sibling tools, this omission is significant.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, openWorldHint=true. The description adds that the tool returns OHLC, volume, and percentage changes, which is useful but does not go beyond what annotations imply. No behavioral contradictions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two concise sentences, 29 words. Front-loaded with the core purpose. Every sentence adds value without redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema is provided. The description mentions key data fields but does not specify format, pagination, or limits. For a historical data tool, this is adequate but leaves some gaps about response structure.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so the description's addition of OHLC, volume, and percentage changes adds some context to the data returned, but it does not directly explain the parameters (symbol, from_date, to). The schema already describes them adequately.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it provides comprehensive historical end-of-day forex data with OHLC, volume, and percentage changes. It distinguishes itself from the sibling 'getForexHistoricalLightChart' by using 'full' and 'comprehensive', but does not explicitly name the alternative.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives. There is no mention of when to prefer 'full' over 'light' or other historical data tools, leaving the agent without decision support.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare this as a read-only, idempotent, open-world operation. The description adds that it returns 'real-time price changes and updates', which is consistent. However, it does not disclose potential limitations such as rate limits, the number of pairs allowed, or data freshness beyond 'real-time'. It does not contradict annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences long and front-loaded: it immediately states the core action and resource. Every sentence adds value without redundancy. No wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the lack of an output schema, the description should hint at return fields (e.g., bid, ask, price, change). It mentions 'price changes and updates' but is vague. The single parameter 'short' is not explained in the description. For a low-complexity tool, it is functional but could better prepare the agent for response handling.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has one parameter ('short') with a description in the schema itself, achieving 100% coverage. The tool description does not add any additional meaning or context about the parameter (e.g., what 'short format' means or how it affects output). Baseline 3 is appropriate as schema already documents it.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it retrieves real-time quotes for multiple forex pairs in a single batch request. It uses specific verbs and resources ('Retrieve real-time quotes') and distinguishes from siblings like getForexQuote (single pair) by emphasizing 'multiple' and 'batch'. However, it could be more precise about what fields are returned (e.g., bid, ask, price).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies batch usage but does not explicitly state when to use this tool versus alternatives like getForexQuote or getForexBatchQuotes. No when-to-use or when-not-to-use guidance is provided, and no alternative tools are mentioned despite many available (e.g., getForexQuote, getForexShortQuote).
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and openWorldHint. The description adds the term 'real-time information', which aligns with these hints but provides no additional behavioral context beyond what annotations convey. Hence, a modest score.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, front-loaded with the main action ('Track'), no redundant wording. Every phrase contributes to understanding the tool's purpose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple one-parameter tool with good annotations, the description is adequate but lacks output details (no output schema) and does not mention the nature of returned data (e.g., list of trades). It could be more complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Input schema has one parameter with a description ('symbol'), and schema coverage is 100%. The description does not add any extra meaning or format details about the symbol parameter, so it meets the baseline but adds no value.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool tracks U.S. House trades with a specific verb ('Track') and resource. However, it does not differentiate from the sibling tool 'getHouseTradesByName', which likely filters by congressperson name, so purpose clarity is slightly reduced.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives like 'getHouseTradesByName' or 'getSenateTrades'. The description implies general tracking but lacks explicit context or exclusions.

Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint and idempotentHint. Description adds that it's a bulk endpoint, but does not mention rate limits, data freshness, authentication, or return structure. No contradictions with annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, front-loaded with purpose. No fluff, but could be more structured (e.g., listing key features).
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema, and description fails to explain how multiple companies are specified (no symbol parameter). The 'bulk' aspect is vague. Incomplete for a tool that likely requires company selection.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with descriptions for both 'year' and 'period'. The description only vaguely mentions time trends, adding little meaning beyond the schema. Baseline 3 applies.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences and relatively concise. The first sentence could be streamlined by removing the redundant API name reference, but overall it is efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With no output schema, the description should clarify return format (e.g., fields like open, high, low, close, volume). It does not, and given many sibling tools, it could better distinguish its purpose.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so parameters are already documented. The description does not add new meaning beyond mentioning 'price movements and trading volume,' which is not parameter-specific.

Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations provide readOnlyHint, idempotentHint, and openWorldHint, so the safety profile is clear. The description adds that it retrieves news but does not disclose pagination behavior, rate limits, or response format. It is adequate but not enriched beyond annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, front-loaded with action and resource. No unnecessary words. Perfectly concise.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given 5 parameters and no output schema, the description is somewhat complete but lacks explanation of pagination and response structure. It adequately covers the core function but leaves out optional behavioral details.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so the description adds minimal value. It mentions 'name' which does not match the schema's 'symbols' parameter, causing slight confusion. Otherwise, it does not provide deeper meaning beyond what schema descriptions already cover.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool searches for cryptocurrency news with a specific verb ('Search'/'Retrieve') and resource ('cryptocurrency news'). It mentions entering name or symbol, though 'name' is not in the schema, which slightly detracts. Among siblings (getCryptoNews, searchStockNews), it is not explicitly differentiated.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives like getCryptoNews or searchStockNews. The description does not specify use cases, prerequisites, or when not to use it.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate read-only, idempotent, and open-world hints. Description adds no extra behavioral context beyond stating 'find latest developments', which is vague. Does not mention pagination, rate limits, or other traits.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With 19 optional parameters, no required parameters, and no output schema, the description adequately identifies it as a filter tool. However, it does not clarify default behavior (e.g., returns all stocks if no filters) or the output format, leaving some gaps for a comprehensive understanding.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% (all 19 parameters have descriptions). The description only names a few parameters but does not add explanatory value beyond what the schema already provides, earning the baseline score.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it is a stock screener to filter stocks by various criteria like market cap, price, volume, beta, sector, country. It effectively communicates the tool's function but does not explicitly differentiate from sibling tools such as getBiggestGainers or getMostActiveStocks.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description lacks guidance on when to use this tool versus alternative screening or list tools. There is no mention of prerequisites, when not to use it, or scenarios where other tools would be more appropriate.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, openWorldHint, indicating safe, idempotent, open-world behavior. The description adds the source API name but no additional behavioral traits (e.g., pagination, rate limits). No contradiction with annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two concise, front-loaded sentences with no wasted words. Every sentence adds value.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a zero-parameter, no-output-schema tool, the description is nearly complete. It could mention that it returns a list of gainers, but the purpose is clear. Among many sibling tools, additional context on output format would help but is not critical.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Input schema has 0 parameters with 100% coverage, so the baseline is 3. The description adds no parameter information, which is acceptable since no parameters exist.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool retrieves stocks with largest price increases using the Top Stock Gainers API. It distinguishes from the sibling 'getBiggestLosers' by focus on gainers, but does not explicitly mention that contrast.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives like 'getMostActiveStocks' or 'getQuote'. No context on prerequisites or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already provide readOnlyHint, idempotentHint, openWorldHint. The description adds minor context about the API source and data scope but does not supplement notable behavioral traits (e.g., authentication, rate limits, response size).
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, front-loaded with action and resource. Mentions the API source, which is slightly redundant but not overly verbose. Efficient overall.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema exists, so description should compensate. It lists some fields (stock price, market cap, industry) but is vague ('much more') and does not specify return format or structure. Adequate but not comprehensive.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% for the single parameter, with a minimal description 'CIK number'. The description does not add extra meaning, format constraints, or examples beyond the schema, so baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it retrieves company profile data by CIK, and mentions specific data fields (stock price, market cap, industry). It uniquely identifies the tool's resource (CIK) and differentiates from siblings like getCompanyProfile (by symbol).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives (e.g., getCompanyProfile for symbol-based lookup). Agents are not told the context for preferring CIK over other identifiers.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate readOnlyHint=true, idempotentHint=true, and openWorldHint=true. The description adds that the tool evaluates market dynamics and potential reversals, which is helpful but does not disclose additional behavioral traits beyond the annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single concise sentence that front-loads the purpose. It is relatively efficient, though it could be slightly more structured for clarity.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description explains what the tool does but does not mention what the output contains (e.g., numeric indicators, text summaries). Since there is no output schema, the description should provide some indication of return values. This gap reduces completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema covers all parameters with descriptions (100% coverage). The description mentions 'specific date range' aligning with from_date and to, but adds no significant extra meaning beyond what the schema already provides.

Two concise sentences with front-loaded purpose. No wasted words, efficiently communicates the tool's function.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (single parameter, read-only) and supportive annotations, the description is mostly complete. However, it could better differentiate from similar sibling tools like getIndexQuotes.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100% for the single parameter. The description does not add additional meaning beyond the schema's example, so baseline score of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool accesses real-time stock index quotes and lists example metrics. It distinguishes from forex/crypto tools but does not differentiate from similar sibling tools like getIndexQuotes or getIndexShortQuote.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool vs. alternatives such as getIndexQuotes or getIndexShortQuote. No conditional context or exclusions provided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences that are efficient, though the second sentence is somewhat redundant. No unnecessary fluff, but could be slightly tighter.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With one well-documented parameter and good annotations, the description is largely complete. However, it omits details on pagination or result limits, which would be helpful for a search tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with a clear description for the 'name' parameter. The description echoes this without adding new semantics, so baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states the tool searches for equity offerings by company name or stock symbol, distinguishing it from other search tools like searchCompaniesByName or getLatestEquityOfferings.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use this tool versus alternatives such as getEquityOfferingsByCIK or getLatestEquityOfferings, nor when not to use it.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations (readOnlyHint=true, idempotentHint=true) already disclose core safety and idempotency. The description adds context about the kind of data but does not discuss additional behaviors like pagination, rate limits, or response structure, which could be expected for a data retrieval tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two concise sentences front-load the purpose and scope. No filler, but could be slightly sharper by eliminating the redundant 'Acquisition Ownership API' mention.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description explains the tool's domain and purpose but omits output details (e.g., fields returned), which is notable given the lack of an output schema. For a simple tool with strong annotations, it is adequate but not comprehensive.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 100% schema coverage, the schema already describes both parameters (symbol and limit). The description does not add extra meaning beyond the schema, so it meets the baseline without compensating for any gaps.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses a specific verb ('Track changes') and resource ('stock ownership during acquisitions'), clearly distinguishing this tool from siblings like getLatestMergersAcquisitions which likely list M&A events rather than ownership impacts.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for tracking ownership changes in acquisitions but provides no explicit guidance on when to use this tool vs. alternatives like searchMergersAcquisitions or getLatestMergersAcquisitions, nor does it mention exclusions or prerequisites.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations provide readOnlyHint, idempotentHint, and openWorldHint. The description adds value by detailing the data content (SIC codes, contact info) and specifying 'across all sectors'. No contradictions, and it provides useful behavioral context beyond the annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, front-loaded with the main purpose, no unnecessary words. Efficient and well-structured.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema and two parameters, the description adequately explains what the tool returns. It could mention pagination explicitly, but the schema implies it. Overall sufficient context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema has 100% coverage with descriptions for page and limit. The description does not add any additional semantics for parameters; it only describes the output. Baseline 3 applies.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states it accesses industry classification data and lists specific fields (SIC codes, industry titles, contact info). However, it does not explicitly distinguish itself from sibling tools like getIndustryClassificationList or searchIndustryClassification, which may have different scopes.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5

The description adds context about the data fields returned but does not disclose any additional behavioral traits beyond what annotations provide. It does not contradict annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description consists of two sentences, is front-loaded with the action verb 'retrieve', and contains no unnecessary words or information. Every word contributes to clarity.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (2 parameters, no output schema), the description adequately covers the purpose, input parameters, and output fields. The annotations provide safety information. There is no missing critical information like pagination or rate limits for this straightforward retrieval task.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 100% description coverage for two parameters (symbol and active). The description does not add any additional meaning or constraints beyond the schema, so it stays at the baseline of 3.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool retrieves detailed information on company executives, specifying fields like name, title, compensation, gender, and year of birth. The verb 'retrieve' and resource 'company executives' are precise, and it distinguishes itself from sibling tools like getExecutiveCompensation which focuses only on compensation.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description does not provide any guidance on when to use this tool versus alternatives such as getExecutiveCompensation, or any exclusions or prerequisites. It simply states what the tool does without contextual usage advice.

Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations (readOnlyHint, idempotentHint, openWorldHint) already indicate a safe, idempotent read operation. Description adds 'detailed information' but does not provide additional behavioral context such as rate limits, data freshness, or any side effects. With annotations present, the description adds only marginal value.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences containing only essential information. Front-loaded with verb and resource. No unnecessary words or repetition.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the single parameter and read-only nature, the description adequately covers the tool's purpose and example outputs. However, it lacks details on return structure (e.g., array or object), pagination, or whether all notes or only active ones are returned. Output schema is absent, so description could provide a bit more structure, but overall sufficient.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100% for the single parameter 'symbol', which is already described as 'Stock symbol'. The description mentions 'stock symbol' as part of the data but does not add new meaning or constraints. Baseline is 3 due to high schema coverage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states the tool retrieves detailed information about company-issued notes, lists specific data fields (CIK, symbol, title, exchange), and uses a specific verb 'Retrieve'. It distinguishes itself from sibling tools like getCompanyProfile which are about company profiles, not notes.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives. Description does not mention when not to use it or provide comparisons to similar tools. Agent must infer context from the name and siblings.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate read-only, idempotent, and open-world behavior. Description adds some example fields but no additional behavioral details like authentication, rate limits, or response structure beyond what annotations imply.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two concise sentences with no fluff. First sentence states the action, second provides key examples. Efficient and well-structured.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema, the description provides a reasonable list of example output fields (market cap, price, industry) and hints at more. Lacks details on data format or freshness, but sufficient for a simple tool with one parameter.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Parameter 'symbol' is fully described in the schema as 'Stock symbol'. The description does not add extra meaning, format constraints, or examples, so it adds no value beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
Clearly states the tool retrieves detailed company profile data for a stock symbol, listing example fields like market cap and industry. However, with many sibling tools, it does not explicitly differentiate itself from similar ones like getCompanyProfileByCIK or getCompanyExecutives.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?

Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is composed of two succinct sentences. The first sentence conveys the core purpose, and the second adds context about the API and market segments. It is front-loaded and contains no superfluous information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool has no parameters and no output schema. The description explains what data is accessible but does not describe the return structure or how to interpret the list. For a simple listing tool, it is adequate but leaves the agent without details on the output format.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With zero parameters and schema coverage at 100%, the description does not need to elaborate on parameter semantics. The mention of 'by commodity or futures contract' implies possible filtering but the schema has no properties, so the description is consistent and adds no confusion.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: 'Access a comprehensive list of available Commitment of Traders (COT) reports by commodity or futures contract.' It uses a specific verb ('access'), identifies the resource ('list of COT reports'), and differentiates from sibling tools like getCOTAnalysis and getCOTReports by focusing on the list.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?

Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two concise sentences with front-loaded purpose. No fluff or redundant content. Every sentence earns its place.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Without an output schema, the description should explain what data is returned (e.g., price, volume, timestamps). It only mentions 'real-time, intraday price data' but omits the response structure, which is a significant gap for a data API.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so the baseline is 3. The description adds no additional meaning to the parameters (symbol, from_date, to) beyond what the schema already provides.

Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool retrieves a comprehensive schedule of upcoming dividend events for all stocks, specifying record dates, payment dates, declaration dates, and dividend yields. This distinguishes it from sibling tools like getDividends (which likely returns data for a single stock) and other calendars.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies use for monitoring upcoming dividend events but does not explicitly state when to use this tool over alternatives like getDividends, getEarningsCalendar, or getStockSplitCalendar. No when-not guidance is provided, leaving the agent to infer from context among many sibling tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, openWorldHint. The description adds that it includes estimated and actual EPS, which is useful but minimal. No contradictions.

Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Input schema coverage is 100%, with both 'symbol' and 'limit' described clearly. The description adds minimal extra meaning beyond the schema; it mentions 'specific stock symbol' but that is already present. The limit parameter's default and max are in the schema but not in the description, so no additional value is provided.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it retrieves earnings information for a specific stock symbol, listing specific data types (dates, EPS estimates, revenue projections). This distinguishes it from sibling tools like getEarningsCalendar (which likely lists earnings dates for many stocks) and getEarningsTranscript (which provides full transcript text). The verb 'Retrieve' and resource 'earnings information' are specific and unambiguous.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description does not provide any guidance on when to use this tool versus alternative earnings-related tools in the sibling list (e.g., getEarningsCalendar, getEarningsSurprisesBulk, getEarningsTranscript).

Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Implied usage for analyzing financial performance via management communication, but no explicit guidance on when to use this tool over siblings or when not to use it.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Description aligns with annotations (readOnlyHint, idempotentHint) but adds no extra behavioral context such as pagination or output format beyond what annotations already convey.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, front-loaded with core function; some marketing language ('identify potential investment opportunities') is minor fluff but doesn't detract.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple one-param tool, description adequately states input and purpose but does not specify output fields or details, leaving some uncertainty about return value richness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% for the single parameter, and description adds no new meaning beyond the schema's 'CIK number to search for'; baseline 3 applies.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states the tool accesses detailed equity offering information for specific companies via CIK, distinct from sibling tools like 'searchEquityOfferings'.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use this tool versus alternatives like searchEquityOfferings; the description implies use for specific CIKs but lacks when-not-to-use or alternative comparisons.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate read-only, idempotent, open-world. Description adds content about returned data (assets, shares, weights, financial info) but does not disclose pagination details or other behavioral constraints beyond the schema.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, front-loaded with primary purpose, followed by a detail. No redundancy or unnecessary words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple bulk retrieval tool with one parameter and no output schema, the description adequately covers what data is returned. However, it could specify that results are for multiple ETFs or provide more context on pagination.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with a brief description for the 'part' parameter. The description does not add meaning beyond 'Part number (e.g., 0, 1, 2)', missing explanation of how parts combine to form the full bulk result.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool retrieves detailed information about assets and shares held by ETFs, including weight and financial info. It distinguishes from siblings like getFundHoldings by emphasizing 'bulk' retrieval.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use this tool versus alternatives like getFundHoldings or getETFList. The description merely states what it does, without exclusions or context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations (readOnlyHint, idempotentHint, openWorldHint) already communicate safe read-only behavior. The description adds value by specifying the output provides percentage allocations by country, which is not in annotations. No contradiction detected.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Three sentences: the first clearly states purpose, the second elaborates on the output, and the third is somewhat redundant ('helping you make informed investment decisions'). Could be slightly tighter but overall efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool is simple with one parameter and no output schema. While the description conveys the general purpose and output type (percentage allocations), it lacks details on the return format (e.g., array of country objects, data types). Adequate but not thorough.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Input schema has 100% coverage with a single 'symbol' parameter described as 'Fund symbol'. The description does not add any additional semantics beyond what the schema already provides, so baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool retrieves country allocation data for ETFs and mutual funds, using specific verbs ('Gain insight' implies retrieval) and specifies the resource. It differentiates from siblings like getFundSectorWeighting and getFundHoldings by mentioning countries and percentage of assets.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use this tool versus alternatives like getFundSectorWeighting or getFundHoldings. The description lacks context for when this is the appropriate tool and provides no exclusions or prerequisites.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate read-only, idempotent, and open-world traits. The description adds that it returns sector percentages, which is core behavior. However, it does not disclose any additional behavioral traits (e.g., data format, limits) beyond what annotations and schema imply.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences, with the second sentence being an illustrative example that adds little actionable guidance for an AI agent. It is slightly verbose but still efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With no output schema, the description should clarify the return format. It vaguely mentions 'breakdown of percentages per sector', which is adequate but could be more precise (e.g., list of objects with sector and weight). For a simple tool, it is marginally sufficient.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with a single parameter 'symbol' described as 'Fund symbol'. The description does not add any extra meaning or context for this parameter, so baseline score applies.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool provides a breakdown of ETF sector weightings, using a specific verb ('provides') and resource ('percentage of an ETF's assets invested in each sector'). This differentiates it from siblings like getFundCountryAllocation or getFundAssetExposure.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description gives an example scenario but does not explicitly state when to use this tool over alternatives or when not to use it. Siblings like getFundCountryAllocation and getFundAssetExposure are not mentioned, so guidance is only implied.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate readOnlyHint=true and idempotentHint=true. The description adds minimal extra behavior details (date, price, volume). No contradictory information, but lacks depth on rate limits, pagination, or data freshness.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, directly stated. No unnecessary words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple historical data tool with 3 parameters and no output schema, the description covers input and output data fields. However, it does not mention that 'to' is optional or default date ranges, and lacks detail on the 'light' aspect vs full chart.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
All three parameters are documented in the input schema with full coverage. The description does not add additional meaning beyond the schema, such as format constraints or default behaviors.

Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already provide readOnlyHint, idempotentHint, and openWorldHint, which cover the safety and side-effect profile. The description adds no behavioral traits beyond stating it accesses historical data. No conflicts with annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence and gets the point across. It includes a slightly redundant phrase 'using the Historical Market Sector Performance API' which could be omitted, but overall it is concise and well-front-loaded.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has 4 parameters (1 required), annotations present, and no output schema, the description is adequate but could be more complete. It does not mention what the response looks like (e.g., data granularity, time periods) or any important usage notes. Still sufficient for a simple data retrieval tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with descriptions for all 4 parameters. The description does not add any additional meaning beyond what the schema already provides. Baseline 3 is appropriate.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool has 2 parameters and no output schema. The description explains the purpose and use cases but does not describe the return structure or data fields in the income statement. This is adequate given the simplicity but leaves the agent guessing about the response format.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema describes both parameters (symbol, limit) with clear descriptions, achieving 100% schema description coverage. The description adds no additional parameter meaning beyond what the schema provides, so a baseline score of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool accesses real-time income statement data for public companies, private companies, and ETFs, with specific verbs like 'access' and 'track'. However, it does not differentiate from siblings like 'getIncomeStatement' or mention 'TTM' (trailing twelve months) in the description, which would help distinguish it.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for tracking profitability and trends but provides no explicit guidance on when to use this tool versus alternatives like 'getIncomeStatement' or 'getIncomeStatementGrowth'. With many sibling tools, more explicit direction would improve the score.

Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool calculates standard deviation for a stock using a specific API. It mentions analyzing volatility and risk, which helps understand its purpose. However, it does not differentiate from sibling technical indicator tools like getSMA or getRSI.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies using the tool for volatility and risk analysis of historical price data. It does not provide explicit when-to-use or when-not-to-use guidance, nor does it mention alternatives among the many sibling indicator tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and openWorldHint, covering safety and idempotency. The description adds that the tool returns counts of rating categories, which is useful context but does not disclose additional behavioral traits beyond what annotations provide.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is three sentences, each adding value: purpose, content, benefit. No redundant or filler words. Front-loaded with the key action 'access an overall view'.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (one required parameter, no output schema, read-only), the description sufficiently explains what the tool returns and its use case. It could optionally mention the data format (e.g., object with counts), but the current text is adequate for agent invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has one parameter 'symbol' described as 'Stock symbol'. The description does not add further semantics about the parameter (e.g., format, case-sensitivity). Since schema coverage is 100%, a baseline of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool provides a consolidated summary of analyst ratings (strong buy, buy, hold, sell, strong sell) for a stock symbol. It distinguishes from siblings like getStockGrades (which may provide individual grades) by emphasizing 'summary' and 'overall view', but does not explicitly contrast with sibling tools.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The phrase 'Quickly access an overall view' implies the tool is for quick summary retrieval, but there is no mention of scenarios where it should not be used or alternatives. Usage context is only implied.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and openWorldHint. The description adds that the tool returns 'split date and ratio' but does not disclose any additional behavioral traits like pagination or rate limits.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Description is three sentences, front-loaded with purpose. Could be slightly more concise (e.g., remove 'Stay informed about'), but no wasted words. Efficient for the information provided.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema, the description explains the core output (date and ratio). However, it lacks details on response structure, pagination, or any limitations. For a simple calendar tool, this is adequate but not complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with from_date and to described as dates. The description does not add meaning beyond the schema; it only mentions the output fields (date and ratio) without linking to parameters.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it provides 'upcoming stock splits' with 'split date and ratio', using specific verb 'provides' and resource 'Stock Splits Calendar'. It distinguishes from siblings like getStockSplits (likely historical) by specifying 'upcoming'.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies use for upcoming splits but does not explicitly state when to use this tool versus alternatives like getDividendsCalendar or getStockSplits. No when-not-to-use guidance is provided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and openWorldHint. The description adds types of changes but no extra behavioral context like pagination, rate limits, or response structure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences with no waste, but the first sentence is slightly promotional ('Stay informed...') rather than purely descriptive. Front-loads intent well.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema exists, so the description should explain return format. It mentions reasons for changes but lacks detail on output fields (e.g., old/new symbol, date). Adequate but not complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so the schema fully documents both parameters. The description does not add meaning beyond what the schema provides, meeting the baseline.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description explicitly states it tracks symbol changes due to mergers, acquisitions, stock splits, and name changes, which clearly distinguishes it from sibling tools like getHistoricalSP500Changes or getDelistedCompanies.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?

Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, and openWorldHint=true. The description adds that the tool returns open, high, low, close prices and volume, which is helpful but minimal beyond annotations. No mention of side effects, auth needs, or rate limits.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences, front-loading the main purpose. It is efficient with no fluff, though slightly verbose with repetitive 'without split-related changes'. Could be tighter but effectively concise.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema exists, so description must explain return data. It mentions OHLCV and volume, which is adequate for a chart tool. However, it lacks details on date range behavior (e.g., pagination, limits) and does not clarify that from_date and to are optional. Adequate but not complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Input schema has 100% coverage with descriptions for all three parameters (symbol, from_date, to). The description repeats the unadjusted nature but adds no new meaning or format details beyond the schema. Baseline 3 is appropriate as description does not compensate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool retrieves unadjusted stock price data, specifically 'without adjustments for stock splits,' and mentions the API source. It uses specific verbs ('access') and resource ('Unadjusted Stock Price Chart'), effectively distinguishing it from adjusted chart tools.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and openWorldHint. The description adds that results include headlines, snippets, and URLs but does not disclose pagination behavior, rate limits, or authentication needs. Adequate but minimal value beyond annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
A single, well-structured sentence that front-loads the purpose ('Stay informed with latest cryptocurrency news') and includes key result details. Every word earns its place.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool has 4 parameters and no output schema. The description mentions headline, snippet, and URL fields but omits details on pagination behavior and date range effect. Adequate for a simple tool but missing modest additional context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so baseline is 3. The description does not add any meaning beyond the schema parameter descriptions (from_date, to, page, limit). No elaboration on date format or pagination.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool retrieves cryptocurrency news with specific verbs ('stay informed' and 'access') and resource ('cryptocurrency news articles'). It distinguishes from siblings like searchCryptoNews (focused on search) and other news tools (forex, stock).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies general crypto news retrieval but does not explicitly state when to use this versus alternatives like searchCryptoNews, getGeneralNews, or stock-specific news tools. No exclusions or context are provided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, openWorldHint. The description adds context about dividend adjustments and end-of-day data but does not reveal further behavioral traits (e.g., rate limits, data granularity). It does not contradict annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences, front-loading the purpose and key benefit. Every sentence adds value without verbosity.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema exists, and the description only mentions 'price and volume data' without specifying the response structure or fields. For a data retrieval tool, this is an adequate but not complete specification.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with clear descriptions for symbol, from_date, and to. The description adds no additional meaning beyond what the schema provides, so baseline score of 3 is appropriate.

Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies use for dividend-adjusted trend analysis but does not explicitly state when to prefer this over alternatives like getUnadjustedChart, getFullChart, or getLightChart. No exclusions or alternative recommendations are provided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, openWorldHint=true, indicating safe, repeatable, cacheable behavior. The description adds that it returns a list with transcript count, but doesn't disclose additional behavioral traits like rate limits or data freshness.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, each conveying essential information without redundancy. Front-loaded with the core purpose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description is adequate for a parameterless list retrieval, but lacks detail on output structure (e.g., fields like symbol, companyName, count) and whether pagination exists. With no output schema, more clarity on return format would improve completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has zero parameters, so schema coverage is 100%. The description adds no parameter information, which is acceptable since there are none. A baseline of 4 is appropriate because the description doesn't need to compensate for missing schema details.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool accesses earnings transcripts and retrieves a list of companies with their transcript count. It uses specific verbs (access, retrieve) and resource (earnings transcripts), distinguishing it from related tools like getEarningsTranscript or getEarningsTranscriptDates.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives. Sibling tools like getEarningsTranscript, getEarningsTranscriptDates, and getLatestEarningsTranscripts exist, but no mention of when to prefer this tool.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and openWorldHint. The description adds marginal behavioral context (e.g., real-time, performance changes) but does not detail response format or limitations, which are not covered by annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise (two sentences) and front-loaded with purpose. The mention of 'with the FMP ETF Price Quotes API' is slightly redundant but not harmful.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (one optional param, no output schema) and annotations covering safety, the description is fairly complete. It mentions key aspects (real-time, performance changes) but could clarify output format slightly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with the boolean parameter 'short' already explained in the schema. The description adds no new parameter information, so baseline score of 3 applies.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool gets real-time price quotes for ETFs, using specific verbs and resource type. It distinguishes from siblings like getQuote (stocks) by explicitly focusing on ETFs.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for ETFs but does not explicitly differentiate from other quote tools (e.g., getIndexQuotes, getMutualFundQuotes). No when-to-use or when-not-to-use guidance is provided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate read-only, idempotent, open-world; description adds no additional behavioral context beyond that.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Implies usage for comparing industry benchmarks but does not explicitly state when to use versus alternatives or provide exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and openWorldHint. The description adds context about the data scope but no extra behavioral traits. No contradiction with annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Single concise sentence, front-loaded with verb and resource, no extraneous information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description is adequate given no output schema, but could be enhanced by hinting at the return structure or multiple periods. Sibling tools have similar detail.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with descriptions for all three parameters. The description adds no additional parameter meaning beyond what the schema provides.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb (retrieve), resource (financial statements as reported), and scope (comprehensive across income, balance sheet, cash flow). It distinguishes from sibling tools like getBalanceSheetStatementAsReported by emphasizing full combined statements.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies use for detailed analysis of original-form statements but does not explicitly differentiate from siblings like individual statement tools or provide when-not-to-use guidance.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate the tool is read-only, idempotent, and open-world. The description adds minor context about the list being 'comprehensive' and covering major global exchanges, but does not disclose any behavioral traits beyond what annotations provide.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two concise sentences, front-loaded with the core action. No unnecessary words or redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
While the tool has no parameters and annotations cover safety, the description is slightly misleading by suggesting the tool itself provides financial data (income statements, etc.), which may confuse agents. It lacks clarity on output format. Given low complexity, completeness is adequate but flawed.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
There are no parameters, and the schema coverage is 100%. The description adds meaning by explaining what the tool returns (list of symbols with financial statement availability), which is necessary since the schema provides no information. Baseline for 0 params is 4.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool accesses a list of companies with available financial statements, specifying its purpose as providing symbols for companies with such data. This distinguishes it from sibling tools that retrieve specific financial data or other symbol lists.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description does not explicitly state when to use this tool versus alternatives like getCompanySymbols or searchSymbol. Usage is only implied through the purpose, but no exclusions or context for choosing this tool are provided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and idempotentHint=true, so the description's mention of 'Access historical data' aligns with these traits. The description adds value by specifying the nature of the data (composition changes, performance), but does not contradict annotations or reveal additional behaviors beyond what annotations imply.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two concise sentences that front-load the action ('Access historical data') and efficiently convey the tool's purpose and capabilities with no extraneous words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description covers both primary aspects (composition changes and performance) of the return value despite having no output schema. It is sufficiently complete for a read-only, parameterless tool, though a bit more specificity about the output format would improve completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has zero parameters, so the description carries no parameter burden. Per guidelines, baseline is 4. The description does not attempt to describe parameters (none exist), so it meets the minimum expectation.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool accesses historical data for the Dow Jones Industrial Average, including composition changes and performance. The tool name already differentiates it from siblings like getHistoricalSP500Changes, but the description does not explicitly contrast them, leaving some ambiguity among the many similar historical index tools.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives like getHistoricalSP500Changes or getHistoricalNasdaqChanges. The description does not mention prerequisites, context, or exclusions, leaving the agent to infer usage solely from the tool name.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the simple parameters and absence of output schema, the description adequately sets expectations for what the tool returns, though it could mention how to find valid exchange codes.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 100% schema description coverage, the schema already explains all parameters. The description adds no additional meaning beyond what the schema provides.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'Access' and the resource 'holiday schedules for specific stock exchanges', distinguishing it from siblings like getExchangeMarketHours which focus on market hours.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description indicates when to use the tool (to get holiday schedules for a specific exchange) but does not mention when not to use it or provide alternative tools, leaving some ambiguity.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and idempotentHint=true, and the description is consistent with read-only behavior. However, the description adds no additional behavioral details (e.g., pagination defaults, date range handling) beyond what annotations imply, so it contributes little extra transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, succinctly front-loaded with the purpose. Every sentence is informative and non-redundant. Excellent conciseness.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With no output schema, the description could hint at the response structure (e.g., fields like transaction type, insider name, volume). The tool has many siblings; the description is adequate but not rich enough for an agent to fully understand what data is returned.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Input schema covers 100% of parameters with descriptions, so the baseline is 3. The description does not add extra meaning or context for the parameters (date, page, limit) beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses a specific verb ('Access') and clearly states the resource ('latest insider trading activity'). It distinguishes this tool from siblings like searchInsiderTrades or getInsiderTradeStatistics by emphasizing 'latest' and 'track which company insiders are buying or selling'.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies when to use (to get latest insider trades) but does not provide explicit guidance on when not to use it or mention alternatives. Given the many insider-trading sibling tools, the absence of exclusion criteria or comparative context is a gap.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate readOnly, idempotent, and openWorld hints. The description adds no behavioral details beyond these, such as pagination or rate limits. With annotations covering safety, the description adds minimal context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is short but somewhat vague (e.g., 'Access comprehensive data' is broad). It could be more concise by directly stating it returns Nasdaq constituents. The phrase 'Monitor real-time movements' may imply continuous monitoring, which is not a tool capability.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no parameters and no output schema, the description should specify what the tool returns (likely a list of constituents). It mentions 'companies listed' but does not explicitly state the return format. Sibling tools suggest it returns constituent data, but the description over-promises without detail.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
No parameters exist, so the input schema provides full coverage. The description does not explicitly state that no parameters are needed, but the lack of parameters is self-evident from the schema. Baseline 4 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states that the tool accesses comprehensive Nasdaq index data, including real-time movements and historical performance of listed companies. It is specific to the Nasdaq index, distinguishing it from sibling tools like getSP500Constituents or getDowJonesConstituents.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use this tool versus alternatives. The name is self-explanatory, but the description does not provide context or exclusions, leaving the agent to infer usage from the name alone.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already provide readOnlyHint and idempotentHint, so the description adds context about the data's nature (grading actions over time). No contradiction. However, no additional behavioral traits (e.g., pagination, rate limits) are disclosed beyond what annotations cover. The bar is lowered due to annotation richness, and the description complements well.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, front-loaded with the core purpose. Somewhat verbose with 'from top analysts and financial institutions with the FMP Grades API' but overall efficient and clear.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple single-parameter tool with no output schema and annotations covering safety, the description adequately explains what the tool returns (stock grades, grading actions). It could mention return format or scope, but is sufficiently complete for basic usage.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with a clear parameter description ('Stock symbol'). The description mentions 'specific stock symbols' but adds no syntax or constraints beyond the schema. Baseline 3 is appropriate as schema already documents the parameter.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it retrieves latest stock grades from analysts and financial institutions, explicitly mentioning grading actions (upgrades, downgrades, maintained). It distinguishes from sibling getHistoricalStockGrades by emphasizing 'latest'. Verb 'Access' + resource 'stock grades' provides specific purpose.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use this vs alternatives like getStockGradeSummary, getStockGradeLatestNews, or getStockGradeNews. The description implies it's for latest grades but does not contrast with similar tools or provide exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and idempotentHint=true, so the description's role in transparency is reduced. The description adds that it returns headlines, snippets, URLs, and tickers, but does not disclose pagination behavior, rate limits, or the fact that results are for all stock news without ticker filtering. No contradiction with annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, no redundant words. Front-loaded with the tool's purpose and what data is returned. Efficient and clear.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema exists, so the description should partially compensate. It lists return fields (headlines, snippets, URLs, tickers) but does not specify that the result is an array, nor does it mention that it returns news for all stocks (no ticker filter). Error handling or rate limits are not addressed. Adequate but not thorough.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Input schema covers 100% of parameters with descriptions, so baseline is 3. The description adds no additional meaning beyond the schema; it mentions 'latest' but does not explain date parameter format or defaults. No extra semantic guidance.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool gets the latest stock market news and lists the specific data returned (headlines, snippets, URLs, tickers). It uses a specific verb ('get') and resource ('stock market news'), and the name distinguishes it from sibling news tools for crypto, forex, or general news.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies use for stock news but does not explicitly state when to use this tool versus alternatives like getCryptoNews or getGeneralNews. No when-not-to-use or alternative recommendations are provided. Guidance on date range and pagination is implicit from the parameters but not articulated.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate readOnly and idempotent hints. The description adds context about the returned data (split date and ratio) and the purpose (understanding share structure changes), which is beyond the annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences, concise and front-loaded with the key action. Could be slightly more terse but is clear and efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple two-parameter tool with no output schema, the description adequately explains what data is returned and the purpose. No obvious gaps.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema covers both parameters with descriptions. The tool description does not add any additional meaning or usage details beyond what the input schema provides. Baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it provides stock split details including split date and ratio for a specific company. It distinguishes from the sibling 'getStockSplitCalendar' by focusing on historical details per company, but could be more explicit about the verb.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description tells what the API does but does not specify when to use this tool versus alternatives like getStockSplitCalendar. No explicit when-to-use or when-not-to-use guidance is given.

The description is two concise sentences that front-load the primary purpose and key metrics. Every sentence adds value, with no redundancy or filler. It is well-structured for quick agent comprehension.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has two parameters, no output schema, and annotations, the description covers the main purpose and key metrics. However, it lacks information on the time period (e.g., annual, TTM) and the exact output structure. For a simple data retrieval tool, it is nearly complete but could be slightly more explicit.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Both parameters (symbol and limit) are already described in the input schema with 100% coverage. The description does not add any additional meaning or context about parameter semantics, such as expected symbol format or behavior of the limit parameter, so it meets the baseline but does not exceed it.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool assesses financial strength using the Financial Health Scores API, and it explicitly names specific metrics (Altman Z-Score and Piotroski Score). This differentiates it from sibling tools like getFinancialRatiosTTM and getFinancialScoresBulk, making the purpose unambiguous.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives. It does not mention when not to use it, such as when bulk data is needed (use getFinancialScoresBulk) or when other ratios are required (use getFinancialRatiosTTM). This lack of usage context forces the agent to rely on name alone.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, openWorldHint. The description adds that data is real-time and 1-minute, which is useful but does not disclose other behavioral traits like rate limits or data range. The description adds some value beyond annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences, front-loaded with the core purpose, and contains no unnecessary words. It is concise and well-structured.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool is simple with 3 parameters, annotations, and no output schema, the description adequately explains the purpose and time interval. However, it could mention return format or data coverage to be more complete. It is sufficient for a straightforward data retrieval tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Input schema has 100% description coverage for all 3 parameters; the description does not add additional meaning beyond the schema. Baseline 3 is appropriate as the schema already documents the params well.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool provides real-time 1-minute intraday forex data, specifying the verb 'Access' and the resource '1-minute intraday forex data'. It distinguishes itself from siblings like getForex1HourData by explicitly mentioning the 1-minute interval.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies the tool is for short-term price movements but does not explicitly state when to use it versus other forex interval tools or provide exclusions. The usage context is implied but not directly compared to siblings.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and idempotentHint=true, and the description is consistent with a read-only list retrieval. However, the description adds no additional behavioral context beyond what annotations provide (e.g., rate limits, result size, or refresh frequency). With annotations covering safety, a score of 3 is appropriate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences and fairly concise. The first sentence clearly states the core purpose. The second sentence ('Analyze and track...') is slightly promotional and could be omitted, but it does not significantly bloat the description. Still front-loaded and readable.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has no parameters, no output schema, and a simple purpose (list all forex currency pairs), the description provides sufficient context. It tells the user exactly what the tool returns. No missing information is needed for correct invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The tool has zero parameters and the schema covers 100% of the interface. Per scoring rules, the baseline is 4. The description does not add parameter semantics because there are none, but it implicitly confirms no input is needed. No further explanation is required.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool returns a 'comprehensive list of all currency pairs traded on the forex market.' It specifies the verb ('access') and the resource ('list of all currency pairs'), and implicitly differentiates from sibling tools that retrieve quotes or historical data (e.g., getForexQuote, getForexHistoricalFullChart).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives. It does not mention when not to use it, prerequisites, or any exclusions. For a simple list tool, some context like 'Use this to get the full set of available currency symbols before querying specific pairs' would improve clarity.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and idempotentHint=true. The description aligns by stating 'Access historical employee count data', but adds minimal behavioral context beyond that, such as the mention of 'specific reporting periods'. It does not disclose details like rate limits or response format.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences: first sentence defines purpose, second adds value proposition. No redundant or extraneous information. Every sentence is purposeful and efficiently communicates key information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema and simple parameters with full coverage, the description adequately conveys what the tool does and why it is useful. It could briefly mention the return format (e.g., list of records) but is otherwise sufficient.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, with both parameters ('symbol' and 'limit') already described in the schema. The description does not add any additional meaning or context beyond what the schema provides.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'Access' and the resource 'historical employee count data', and specifies it is for a company based on reporting periods. The name itself includes 'Historical', distinguishing it from the sibling 'getEmployeeCount' which likely provides current data.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for analyzing growth trends and operational changes over time, but does not explicitly mention when to use this vs. 'getEmployeeCount' or other alternatives. No exclusion or conditionals are provided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already state readOnlyHint, idempotentHint, and openWorldHint, which cover safety and idempotency. The description adds value by indicating it provides historical data with key financial metric scores, but it doesn't detail pagination or date selection (since no date parameter exists).
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise (two sentences) and front-loaded with the primary purpose. Every sentence contributes value without redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the simple parameter set (2 params, 1 required) and no output schema, the description sufficiently covers the tool's purpose and data type. However, it omits how historical dates are selected (only limit is available), which may leave ambiguity for the agent.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% (both symbol and limit are described in the input schema). The description reiterates 'stock symbols' and 'optional limit on number of results' but does not add new meaning beyond the schema. Baseline score of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool provides historical financial ratings for stock symbols, with a verb ('track changes' or 'view') and resource ('ratings'). However, it does not differentiate from nearby sibling tools like getHistoricalStockGrades or getRatingsSnapshot, which may serve similar purposes.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?

Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple tool with one parameter and good annotations, the description covers the purpose and output content. However, it lacks information on error handling, multiple returns, or how to interpret the 'conflicts of interest' part. Still, it is largely complete for the tool's simplicity.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% (the only parameter 'name' has a description). The description's mention of 'first or last name' adds minor clarification, but the schema's description already says 'Senator name (first or last name)', so no significant added value.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's verb ('Search for') and resource ('Senate trading activity by Senator name'). It differentiates from siblings like 'getSenateTrades' by specifying the name filter and from 'getHouseTradesByName' by specifying Senate.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage when searching by name, but does not explicitly state when to use this tool over alternatives like 'getSenateTrades' (which may list all trades). No when-not-to-use or alternative guidance is provided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate read-only, idempotent, and open-world behavior. The description adds that rates are real-time and historical for all maturities, which provides extra context without contradicting annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two concise sentences that efficiently convey the tool's purpose and scope. No redundant or unnecessary information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool is simple with no required parameters and no output schema. The description covers the essential purpose and data type. Could mention return format, but not critical for basic selection.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5

Clearly states the tool accesses 'real-time and historical Treasury rates for all maturities' and mentions tracking key benchmarks. The purpose is specific and distinct from sibling tools, which cover other financial data.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives. It does not provide context for optimal use or when not to use it, relying on the agent to infer from the name.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already provide readOnlyHint, idempotentHint, openWorldHint. Description adds context on return fields (CIK, entity info, file number) but no additional behavioral traits like rate limits or authentication. Value added beyond annotations is moderate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences- front-loaded with primary purpose, second sentence adds useful return details. No extraneous text.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple search tool with one parameter and annotations covering safety, the description explains what is returned and references the API. It lacks pagination or limit info but is sufficient for a basic search. Slightly better than adequate.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% and describes 'name' as 'Name of the holder to search for'. Description reinforces 'by name' but does not add new semantic constraints or examples. Baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states 'search for mutual fund and ETF disclosures by name', with specific verb and resource. It distinguishes from sibling tools like getFundDisclosure by indicating it returns multiple disclosures based on name search, and lists expected details (CIK, entity info, file number).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Description implies usage when searching by fund name but does not provide explicit when-to-use or when-not-to-use guidance, nor names alternatives among the many sibling tools. Usage is implied but not differentiated.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations (readOnlyHint, idempotentHint) already declare safety. Description adds 'across multiple global markets' but no additional behavioral traits. Minimal extra value beyond annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
