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

The description adds behavioral context beyond annotations: default model cost (free), BYO API key for Anthropic, and return structure. Annotations already declare readOnlyHint and idempotentHint, and the description complements them without contradiction.

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 (around 100 words), well-structured, and front-loaded with the core action. Every sentence adds value without redundancy.

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?

Despite no output schema, the description fully explains the return value (per-model {score, confidence, signals, raw_response} + combined view). It covers all aspects: purpose, parameters, usage, and results.

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%, and the description adds value by re-explaining parameters with examples (e.g., 'Boston restaurant' for context) and clarifying when _apiKey is needed. It goes beyond the schema definitions.

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's purpose: probing LLMs for knowledge about a business/brand/product/topic and returning a visibility score per model. It specifies the default model and optional Anthropic probing, which distinguishes it from sibling tools like scan_competitor_ai_presence.

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 specific use cases (AI-marketing audits, pre-launch brand checks, competitive monitoring), clearly indicating when to use the tool. However, it does not explicitly mention when not to use it or suggest alternative tools.

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?

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds valuable behavioral context beyond annotations: returns structured answers with 'stable pipeworx:// citation URIs', is 'one fast call', 'works on every tier', and can route to live news. This enriches the agent's understanding of what to expect.

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 longer than average but front-loaded with the key directive 'PREFER OVER WEB SEARCH'. Every sentence contributes value: purpose, examples, alternatives, and a pointer to better options. It could be trimmed slightly (e.g., the long list of domains) but remains well-structured.

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

For a meta-tool that routes to thousands of sources, the description covers purpose, usage triggers, alternatives, output characteristics (structured answer + citations), and examples. No output schema exists, but the description adequately conveys what the agent will receive. It is complete for the tool's complexity.

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 description coverage is 100%, so the baseline is 3. The description provides examples of valid questions ('What was Apple's revenue in 2024?') but does not add much beyond the schema's parameter descriptions. The alias information is in the schema, not the description, so the description adds only marginal value here.

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's function: 'Routes the question to the right one of 5,529 tools across 1455 verified sources, fills arguments, returns the structured answer with stable pipeworx:// citation URIs.'

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?

Provides explicit when-to-use guidance with concrete triggers ('when the user asks "what is", "look up", "find"...') and lists data domains (SEC filings, FDA, FRED, etc.). It also names alternatives and when to step up: 'for a hallucination-resistant single answer... use ask_pipeworx_grounded; for a broad/multi-part question... use deep_research.'

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?

Annotations already declare read-only, idempotent, and open-world hints. The description adds substantial context beyond these: the beta status, live candidate testing, current matching to the stable router, and the fact that results are compared against the stable router. It also clarifies there is no fallback, which is valuable behavioral information not present in annotations.

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?

Annotations already declare readOnlyHint=true, openWorldHint=true, idempotentHint=true, and destructiveHint=false. The description adds valuable behavioral context: data source (CF analytics-engine), privacy (no PII), output structure (pack, tool, count), and caching (5min-1h). No contradictions; enhances understanding 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.

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

Description is concise with front-loaded function statement, followed by bullet-point use cases, then technical notes. Every sentence adds value; no redundancy or filler.

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?

Despite no output schema, the description adequately explains what is returned (top tools, top packs, total call volume). Caching, data source, and privacy are covered. For a simple read-only tool with one optional parameter, this is complete and sufficient.

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 description for the only parameter 'window'. The tool description adds further meaning: 'Shorter windows surface what's hot right now; longer windows show steady-state demand.' This provides actionable guidance on parameter selection beyond the schema's enum.

Provides filtering guidance ('Filter by type and/or since'), mentions polling is fine, and gives an explicit alternative endpoint (registry.pipeworx.io/alerts.json) for scripts and dashboards. Could be more explicit about when not to use, but the alternatives are clear.

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?

Annotations already declare readOnlyHint, idempotentHint, and non-destructive. The description adds substantial behavioral context: fans out to multiple sources, fallback logic, soft-fail for patents, and what the return structure includes (grouped changes, count, citation URIs). No contradictions.

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 longer than ideal but well-structured with examples first, then internal details, then alternative. It front-loads key usage patterns. Could be slightly trimmed without losing substance, but each 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?

Given no output schema, the description explains the return format sufficiently (changes grouped by source, total count, citation URIs). It covers input parameters, data sources, and fallback behavior. However, the exact structure of individual change items is not specified, which might require the agent to infer.

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%, so the schema already documents all 3 parameters. The description adds minor useful context (e.g., recommendations like '30d' for monitoring, enum limitation to 'company'), but does not significantly enhance understanding beyond the schema 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 clearly states that the tool provides a change feed for a company (SEC, news, patents) in a given window. It opens with diverse examples that immediately convey scope, and explicitly distinguishes itself from the sibling 'entity_profile' tool. This makes purpose unambiguous.

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 when-to-use (change feed for recent activity) and when-not-to-use (use entity_profile for static profile). It also describes the fallback mechanism (GDELT→GNews) and soft-fail for patents. This gives clear guidance on tool selection and behavior.

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?

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint=false. Description adds behavioral context: it fetches fake data from DummyJSON and returns specific fields, which is valuable beyond annotations. No contradictions.

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?

Single sentence, no wasted words, front-loaded with action and returns. Efficient and clear.

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 has an output schema (so return details are covered), one parameter, and annotations indicating safe read, the description fully covers purpose, behavior, and parameter meaning. No gaps for the given complexity.

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 description coverage is 0% but description compensates by specifying 'numeric `id` from DummyJSON', giving context about the parameter meaning and source. For a single parameter, this provides sufficient semantics beyond the schema type.

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 it fetches a single fake recipe by numeric ID, listing returned fields (name, ingredients, instructions, etc.). This specifies the verb ('Fetch'), resource ('single fake recipe'), and key attributes, distinguishing it from sibling 'recipes' which likely fetches multiple.

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?

Implies usage for fetching one recipe by ID, but does not explicitly state when to use this vs alternatives like 'recipes'. No direct mention of when-not or alternative tools, leaving the agent to infer from sibling names.

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?

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and non-destructive behavior, covering safety and idempotency. The description adds minimal context by listing return fields (name, ingredients, etc.) but does not disclose additional behavioral traits 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.

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

The description is two sentences with no fluff, front-loading the main purpose and key features. Every sentence contributes meaning.

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?

With an output schema present, the description does not need to detail return values, but it mentions key fields. It covers pagination and field selection. However, it lacks details on default pagination behavior or ordering, which would be helpful for a complete understanding.

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 description coverage is 0%, and the description only names the three parameters (limit, skip, select) without explaining their meanings, constraints, or defaults. While parameter names are somewhat self-explanatory, the description fails to add significant value beyond the schema's property names.

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 fetches a paginated list of fake recipes from DummyJSON, specifying the resource and source. It distinguishes from sibling 'recipe' (singular) which likely retrieves a single recipe.

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 implies usage through list operations with pagination and field selection, but does not explicitly state when to use this tool versus alternatives like 'recipe'. It provides no exclusion criteria or 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.

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

Beyond annotations (idempotentHint, destructiveHint), the description adds critical behavioral context: scoping by identifier, persistence differences between authenticated (persistent) and anonymous (24 hours). No contradictions.

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?

Four sentences with no filler. The first sentence immediately states the purpose, followed by usage guidance and behavioral details. Every sentence 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 simplicity of the tool (2 required params, no output schema), the description covers purpose, usage, behavioral details, and pairing with siblings. No gaps for an agent to misuse it.

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 already describes both parameters (100% coverage). The description adds value by providing concrete examples for the 'key' parameter (e.g., 'subject_property', 'target_ticker') and clarifying the 'value' parameter as any text.

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 specific verb ('save') and resource ('data the agent will need to reuse later'), clearly distinguishing it from sibling tools 'recall' and 'forget' by naming them and explaining the pairing.

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?

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?

Beyond annotations (read-only, idempotent, open-world), the description discloses substantial behavior: internal cascading through multiple lookup endpoints, graceful degradation if GLEIF/OpenFIGI are unavailable, explicit labeling of identifier sources, and explicit reporting of unresolved identifiers. This gives agents a clear model of the tool's edge-case behavior and fallback semantics.

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 lengthy but well-structured, front-loading user-facing query examples and the core purpose. The SUPPORTED TYPES sections are dense with necessary details (source labeling, fallback, unresolved handling). While every sentence earns its place, the length and density could be slightly reduced without losing 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?

It covers return values per type, how unresolved identifiers are presented, source citations, and the internal cascading behavior, leaving few ambiguities for an agent.

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%, so the baseline is 3. The description enriches parameter meaning significantly by explaining what each type returns (e.g., company resolves to CIK, ticker, LEI, FIGI; drug to RxCUI) and by providing input examples. It clarifies expected value formats and output semantics beyond the schema's simple type/value 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 clearly states the tool resolves user-spoken names to canonical/official identifiers, with specific verbs and resource types.

Examples of user queries (e.g., 'What's the ticker for…') make the purpose immediately understandable.

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 gives explicit guidance on when to use the tool ('Use FIRST whenever you have a name but need an ID') and covers supported entity types and input formats. However, it does not explicitly state when not to use it or name alternative tools, so it stops short of full exclusion guidance.

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?

Annotations already indicate read-only, idempotent, non-destructive behavior. The description adds that it probes each entity and returns a ranked list, which is consistent and adds useful context beyond annotations.

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?

With no output schema, the description takes on the burden of explaining the return value (verdict, grounded/structured value with citation, reasoning) and does so thoroughly. It also covers error semantics (could_not_verify), unsupported meaning, and the fast-path/grounded routing, making it complete for a tool of this complexity.

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 already provides 100% coverage with rich descriptions for both claim and tolerance_pct, including examples and default behavior. The tool description does not add parameter-specific details beyond what the schema states, so the 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 identifies the tool as natural-language claim verification, with trigger phrases like 'fact check' and 'verify the claim that...'. It distinguishes itself from sibling tools by explicitly stating it replaces 4–6 sequential calls (NL parsing → entity resolution → data lookup → comparison). It also describes the two distinct processing paths (financial claims via SEC EDGAR/XBRL, other claims via grounded pipeline), making the scope concrete.

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 gives explicit usage context: 'Use whenever the agent needs to check whether something a user said is factually correct.' It also provides nuanced guidance on routing and warns about could_not_verify not being evidence, which is critical for correct invocation. However, it does not explicitly name alternative tools or state conditions where this tool should not be used, so it falls short of a 5.

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