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

Annotations already indicate read-only and idempotent. The description adds that the default model is free, Anthropic requires BYO key with direct payment, and returns per-model data with a combined view. 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?

Three to four sentences with no fluff. The main action and key details are front-loaded: probes, scores (0-100), default model, optional Anthropic, and return format.

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 clearly states the return structure: per-model {score, confidence, signals, raw_response} plus combined view. All four parameters are described sufficiently. No gaps.

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%, but the description adds value by giving examples for 'entity', listing supported models for 'models', explaining the key requirement for '_apiKey', and the disambiguation use for 'context'. Exceeds the baseline for high-coverage schemas.

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 'probe' and resource 'LLMs', clearly stating it scores visibility per model. It distinguishes from sibling tools by focusing on AI brand awareness, not general search or entity profiles.

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 states use cases: 'AI-marketing audits, pre-launch brand checks, competitive monitoring.' It gives context for when to use, though it doesn't explicitly mention when not to use or name 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?

Annotations already indicate readOnlyHint, openWorldHint, idempotentHint, and non-destructive nature. The description adds that the tool routes to thousands of tools and returns structured answers with stable citation URIs, providing additional context beyond annotations.

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

The description is well-structured, beginning with the key directive, then listing domains, explaining the mechanism, and providing usage cues and examples. Every sentence adds information, and the length is justified by the tool's broad scope.

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 complexity (3,745 tools, 884 sources, no output schema), the description thoroughly covers when and how to use it, what to expect (structured answer with URIs), and differentiates it from many siblings. It is complete for an agent's decision-making.

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 has six parameters but all are aliases for 'question' with full coverage. The description adds value by providing example queries, helping the agent understand the type of input expected, which goes beyond the schema's alias 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?

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. The description adds significant behavioral details beyond annotations: it explains refusal reasons (not_in_source, no_tool_match, etc.), return structure (answer, evidence, confidence, source, fetched_at, refusal_reason), and that it uses only the tool result. This enriches transparency well.

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 somewhat long but well-structured: it starts with the core purpose, explains the mechanism, lists the return format, gives usage guidelines, and ends with a cost trade-off. Every sentence adds value, though it could be slightly trimmed without losing 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 tool's complexity, the description is thorough: it covers purpose, routing, extraction process, return format (including refusal reasons), use cases, and trade-offs with the sibling tool. No output schema exists, but the description explicitly defines the return structure, making it complete for an agent to select and invoke correctly.

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 does not add additional meaning to the parameters beyond what the input schema already provides (e.g., the aliases for the question parameter are already documented in the schema). Thus, no extra value added.

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 defines the tool as a hallucination-resistant answer mode for high-stakes reads, distinct from the sibling ask_pipeworx tool. It specifies that it extracts answers only from tool results and refuses if data doesn't directly answer, making its 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?

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?

The description goes far beyond annotations, detailing internal processes like classifier selection, fan-out to specific data sources, response shapes, safety mechanisms (low_confidence_match, market_closed_or_inactive, illiquid_wide_spread), and resolution-rule risk. No contradictions with annotations; all disclosed behaviors align with readOnly, idempotent, and non-destructive hints.

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 long but well-organized with clear sections (CLASSIFIERS, FAN-OUT EXAMPLES, RESPONSE SHAPES, etc.). It front-loads the core purpose. While verbose, every section adds necessary context for a complex tool. It earns a 4 for structure and informativeness, though slight trimming could improve conciseness.

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 complexity (many classifiers, fan-out patterns, safety rules, and response fields) and no output schema, the description provides comprehensive coverage. It explains return shapes, evidence sources, edge cases, and resolution risks. An agent has all necessary context to invoke and interpret results correctly.

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 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: researching a Polymarket bet by pulling Pipeworx data in one call. It specifies input formats (slug, URL, question text) and output (evidence packet + comparison). This distinguishes it from sibling tools like polymarket_edges or polymarket_arbitrage, which focus on edge detection or arbitrage rather than comprehensive evidence gathering.

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 explicitly says 'Use for 'should I bet on X', 'what does the data say about Y', or 'is there edge in Z'', providing clear when-to-use guidance. It also warns about low-confidence matches and closed markets, but does not explicitly name alternatives or when not to use it. However, the context is strong enough for an agent to infer appropriate usage.

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 readOnlyHint=true, idempotentHint=true, destructiveHint=false. The description adds no behavioral context beyond annotations, such as return format or any limitations. It misses an opportunity to add value.

Schema coverage is 100% with both parameters described, but the description adds significant meaning: it provides concrete examples (e.g., 'AAPL', '0000320193', 'ozempic') and explains that for company, the tool accepts ticker, CIK, or name with auto-disambiguation. It also details what each type returns, which is not in 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 starts with concrete user queries ('What's the ticker for…') and explicitly states the tool's purpose: 'resolve a user-spoken NAME to the canonical/official identifier other tools require as input.' It clearly identifies the action (resolve) and resource (entity identifiers), and differentiates itself from siblings by focusing on name-to-ID resolution for other 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 includes explicit guidance: 'Use FIRST whenever you have a name but need an ID.' This tells the agent when to invoke this tool. It does not explicitly mention when not to use it, but the context is clear and it names alternatives implicitly by suggesting it replaces multiple lookups.

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, idempotentHint=true, destructiveHint=false. Description adds valuable context: it probes each entity with ai_visibility_check, ranks by score, and returns score/confidence/signal density. 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.

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

Two focused sentences that quickly convey purpose and behavior, followed by a relevant example. No wasted words; front-loads key information.

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 moderate complexity, lack of output schema, and rich annotations, the description sufficiently explains the return format (ranked list with score/confidence/signal density) and internal process. Nothing critical is missing.

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 covers all 4 parameters with descriptions (100% coverage). Description adds important semantic detail that the first entity in the array is treated as the subject for narrative, which aids correct usage.

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 explicitly states it compares AI visibility across multiple entities side-by-side, using ai_visibility_check internally. It clearly distinguishes from the single-entity sibling ai_visibility_check and provides a concrete use case for competitive audits.

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 a clear use case ('competitive AI-marketing audits') and implies it's for multi-entity comparison. However, it does not explicitly state when not to use it or mention alternatives like compare_entities.

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. Description adds timing details (bundlephobia first measurement takes 5-30s) and graceful degradation with sources_failed field.

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 efficient, front-loaded with core purpose, then structured details and usage guidance. No redundant sentences.

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, description fully explains return fields (summary block, per-advisory details, links, alternative versions) and partial failure behavior. Annotations cover safety and idempotency.

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 covers both parameters fully with descriptions. Description adds minimal extra info (scoped packages accepted, version defaults to latest), but does not significantly enhance understanding beyond 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 it performs a composite check for npm packages across deps.dev and bundlephobia, answering 'should I add this package?' It distinguishes itself from siblings 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?

Explicitly says 'Use whenever an agent asks "is X safe / popular / small"' and clarifies NPM-only in v1, with fallback to deps.dev for other ecosystems.

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, idempotentHint=true, etc. Description adds no additional behavioral details such as pagination, response format, or error conditions.

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 a single vague sentence that does not earn its place. It lacks necessary detail and structure, making it under-specified rather than concise.

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 having an output schema, the description omits usage context, parameter guidance, and differentiation from many sibling tools. With 4 parameters and numerous alternatives, more detail is required for completeness.

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?

Only 25% of parameters have schema descriptions (only 'resources' has one). The tool description fails to explain the other three parameters (query, page, limit) or their syntax, leaving the agent without guidance.

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 says 'Search across all resources' but does not specify which resources or how it differs from sibling 'search_within'. The schema lists resource types but the description fails to clarify scope, making it vague.

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?

No usage context provided. No mention of when to use this tool versus sibling search_within or other search 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?

Discloses beyond annotations: 'BGE-base-en embeddings + cosine over 500-char overlapping windows; cap is 200K chars (longer inputs are truncated and flagged).' Also mentions return format (character offsets, similarity scores). No contradiction with annotations (readOnlyHint, idempotentHint, openWorldHint).

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 (4 sentences), front-loaded with the core purpose, and every sentence adds value – usage guidance, behavioral detail, and pairing advice. No wasted words.

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 explains return values (top-N passages with character offsets and similarity scores), covers behavioral traits (embedding model, chunking, cap, truncation flag), and gives usage context. 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?

Schema coverage is 100%, so baseline is 3. The description adds no new parameter specifics beyond examples for the query. The schema already describes each parameter adequately. Description provides context but does not enrich parameter semantics.

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 is 'Semantic search INSIDE a fetched record' with specific examples like 'a SEC 10-K body, an article, a long tool result'. It distinguishes from sibling tools by focusing on searching within an already-fetched record, and explicitly pairs with ask_pipeworx_grounded for grounded responses.

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 states 'Use when the record is too big to cram into the prompt' and that it 'saves context, returns only the passages that matter'. It also mentions pairing with ask_pipeworx_grounded, but does not explicitly list when not to use or alternative sibling tools like 'search'.

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?

Disclosure goes well beyond annotations: returns new subscription id, explains persistence requirements, details each type's behavior, delivery channel limitations (10/day SMS cap), webhook signing process, and auto-disable after failures. Annotations only hint at idempotence and open-world, so description adds critical 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?

Well-structured and front-loaded with purpose, then details. Contains extensive examples and caveats. Could be slightly more concise, but the thoroughness is justified by the complexity of the tool.

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 complexity (multiple types, nested parameters, delivery options) and no output schema, the description covers prerequisites, return value, all type-specific filters, delivery channel behaviors, limitations, and error conditions (auto-disable). No obvious gaps.

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 covers 100% of parameters with descriptions, but the description adds significant value with concrete examples (ticker, items codes, topics), required field combinations (sponsor or condition for clinical_trial), and delivery format details. This goes beyond schema-only understanding.

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 creates a subscription to a live-data event stream. Uses specific verb 'Create' and resource 'monitoring subscription'. Distinguishes from siblings by enumerating supported types and delivery channels.

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 context on when to use (create subscription), prerequisites (Pipeworx OAuth account), and type-specific parameters. Does not explicitly mention when not to use or compare to siblings like list_subscriptions, but the examples and delivery details offer sufficient 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 provide readOnly, openWorld, idempotent, non-destructive. Description adds that it returns category-bucketed example questions with exact tool+argument shape from a live catalog, and behavior when no topic is given.

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?

Front-loaded with user questions, then explanation. Every sentence adds value but slightly verbose for a simple tool. Nonetheless clear and well-organized.

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?

No output schema, so description explains return structure (category-bucketed with tool+argument shape). Covers all contextual needs for an onboarding tool.

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 has 1 optional param with description. Description adds meaning by listing possible topic values (finance, pharma, etc.) and explaining effect of omission (full cross-category spread).

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 verbs (returns, call) and resources (example questions, category-bucketed). It clearly distinguishes itself from siblings by positioning as the onboarding entry point and referencing meta-tools like ask_pipeworx.

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 states 'Use this FIRST when you do not yet know what Pipeworx can do for you, or to learn how to call the meta-tools.' Also explains when to pass a topic vs omit.

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?

Discloses key behaviors: ownership enforcement, soft-deactivation (not deletion), impact on historical data. Annotations already indicate non-destructive and idempotent; description adds context 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?

Two sentences, each earning its place: first states purpose, second adds behavioral detail. No wasted words.

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?

Covers ownership, deactivation behavior, and historical data impact. No output schema, but description sufficiently explains what happens. Could mention response but not necessary for functionality.

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 description for 'id'. Description does not add further parameter meaning beyond schema. Baseline 3 applies.

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 the action (cancel) and resource (subscription by id), distinguishing from siblings like 'subscribe' and 'list_subscriptions' by specifying ownership enforcement and deactivation (not deletion).

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 clear context: ownership enforced (only own subscriptions), row deactivated not deleted, historical events stay available. Implicitly guides when to use vs deletion, but no explicit exclusions or 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?

Annotations already declare readOnly, idempotent, non-destructive. Description adds return format (verdict, structured form, citation, delta), source (SEC EDGAR+XBRL), and efficiency (replaces 4-6 calls). Adds 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.

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

Concise, front-loaded with trigger phrases, and informative without redundancy. 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?

Given single parameter and no output schema, the description fully explains functionality, domain, output structure, and use case. No gaps.

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 one parameter. Description adds domain context (company-financial claims) and examples via trigger phrases, going beyond the schema's example.

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 performs natural-language claim verification against authoritative sources, with specific trigger phrases. It scopes to company-financial claims, distinguishing it from siblings like ask_pipeworx.
