Linear

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description discloses that the tool selects the best data source and fills arguments, which is behavioral. No annotations are provided, so the description carries the full burden. It does not mention any side effects, authorization needs, or rate limits, but the tool appears to be read-only and non-destructive, which is inferred.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is concise (two sentences plus examples) and front-loaded with the core purpose. Every sentence adds value. The examples are helpful but add length; still appropriate for clarity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the simple input schema (one string parameter), no output schema, and no annotations, the description is largely complete. It explains the tool's behavior and provides examples. It could mention that results are returned as text, but that is implied.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 100% coverage with a single 'question' parameter described as 'Your question or request in natural language'. The description adds context by specifying 'in plain English' and providing examples, but the schema already conveys the essential meaning. Baseline of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states that the tool answers natural language questions by selecting the appropriate data source and filling arguments. It specifies the verb ('Ask'), the resource ('Pipeworx'), and distinguishes it from sibling tools that are more specific (e.g., linear_* tools).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides explicit usage guidance: 'No need to browse tools or learn schemas — just describe what you need.' It gives examples of appropriate questions. However, it does not explicitly state when not to use this tool or mention alternatives.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided, so description carries full burden. Discloses that it returns paired data and resource URIs, and specifies data sources (SEC EDGAR for companies, FDA for drugs). Does not mention any destructive side effects, which is appropriate for a comparison tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Despite lacking output schema, description explains the output nature (paired data + resource URIs). Covers parameters, use cases, and benefit (efficiency). Complete for a straightforward comparison tool with two parameters.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%. Description adds significant meaning beyond schema: explains the 'type' enum values with context (company metrics vs drug metrics), and clarifies the 'values' format (tickers/CIKs for companies, drug names). This helps the agent construct valid inputs.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

Clearly states verb 'compare' with specific resource '2–5 entities side by side'. Distinguishes from siblings by mentioning it replaces 8–15 sequential calls, implying efficiency over repeated individual lookups. The two entity types (company, drug) and their specific metrics are explicitly listed.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 100% coverage with descriptions for both parameters. The description adds value by explaining the return type ('names and descriptions') and giving example queries, which helps the agent formulate effective queries. However, it does not add significant new meaning beyond the schema's parameter descriptions.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses specific verb+resource ('Search the Pipeworx tool catalog') and clearly distinguishes from siblings by stating 'Call this FIRST when you have 500+ tools available and need to find the right ones for your task.' This makes its purpose unique among sibling tools like ask_pipeworx or linear_search.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it returns a full profile of an entity across multiple Pipeworx packs, listing specific data types (SEC filings, XBRL, patents, news, LEI) and distinguishes itself from siblings like resolve_entity and compare_entities.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

It explicitly notes when not to use this tool (for federal contracts, call usa_recipient_profile) and implies using resolve_entity first if only a name is available, providing clear alternatives and context.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description must disclose behavioral traits. It confirms deletion (a destructive operation) but does not mention irreversibility, error handling, or authorization requirements. 'Delete' implies mutation, but the agent needs more context.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence with 6 words, no redundancy, and front-loaded verb 'Delete'. Every word earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's simplicity (1 required param, no output schema, no annotations), the description is adequate but could mention that deletion is irreversible or that the key must exist.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with a single required parameter 'key' described as 'Memory key to delete'. The description adds minimal extra meaning, but the schema already provides full coverage, so a baseline of 3 is adjusted up slightly because the description reiterates the parameter's purpose.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a clear verb 'Delete' with a specific resource 'stored memory' and the qualifier 'by key', distinguishing it from sibling tools like 'remember' (store) and 'recall' (retrieve).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

For a tool with no output schema, the description adequately explains return values (ticker, CIK, name, URIs) and the context that it replaces multiple calls. No missing critical information given the tool's simplicity and sibling tool set.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Input schema has full description coverage, but the description adds valuable examples (ticker, CIK, name) and usage context (v1 only supports company), enhancing understanding beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states 'resolve an entity to canonical IDs' with specific input formats and outputs, distinguishing it from sibling tools like Linear tools or memory tools by noting it replaces 2-3 lookup calls.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly says when to use: to get canonical IDs for a company in a single call, replacing multiple lookups. Implicitly tells agent to use instead of separate lookups, though no explicit 'when not to use' is needed given sibling tools are unrelated.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided, so the description carries full burden. It discloses the return structure (verdict, structured form, actual value with citation, percent delta) and the data source (SEC EDGAR + XBRL). It does not cover potential side effects, auth needs, or rate limits, but for a read-only tool this is acceptable.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Three well-structured sentences: purpose first, then scope and output, finally context. No redundant words; every sentence adds value.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description covers purpose, scope, output, and replacement benefit. It lacks explicit error handling or edge case behavior but is sufficient for a simple single-parameter tool. Could mention what happens if claim is out of scope.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The sole parameter 'claim' has 100% schema description coverage, including an example. The tool description adds further context by providing example formats and clarifying it is natural-language. This adds marginal value beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool fact-checks claims, specifies supported scope (company-financial claims for US public companies), and lists the verdicts returned. It distinguishes from siblings by explicitly replacing 4-6 sequential agent calls, highlighting its unique value.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description indicates when to use (for fact-checking financial claims) and implies limitations by stating 'v1 supports company-financial claims' and 'public US companies'. However, it does not explicitly mention when not to use or compare with sibling tools beyond stating it replaces sequential calls.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
