Two tightly written sentences, front-loaded with the action. No redundant or extraneous 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 simple tool with 2 params, no output schema, and rich annotations, description covers purpose and usage but lacks parameter explanations. Adequate but could be enhanced by describing the 'language' parameter.

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 0% description coverage for parameters. Description mentions 'stable ID' as concept but does not explain the 'id' or 'language' parameters, leaving their meaning and format unclear. Minimal value added 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?

Annotations already indicate readOnlyHint, openWorldHint, idempotentHint, destructiveHint. The description adds that calls cascade through several endpoints internally, which is useful behavioral context. 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 well-structured with examples, bullet-like sections for supported types, and front-loaded key uses. Every sentence provides value; no unnecessary 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 thoroughly covers return values for each entity type and explains internal cascading. It is complete for a resolution tool given the complexity and available annotations.

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 significant meaning: it explains return values for each type (e.g., ticker + CIK for company), provides input examples, and clarifies disambiguation. This goes well beyond 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 starts with clear examples ('What's the ticker for...') and explicitly states it resolves a user-spoken name to a canonical identifier. It distinguishes itself from siblings by noting it replaces 2-3 manual lookups.

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 FIRST whenever you have a name but need an ID.' It implies context for when to use but doesn't list explicit alternatives or when not to use, though the list of supported types gives clear boundaries.

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-destructiveHint. The description adds behavioral details: probes each entity, ranks by score, and returns a ranked list with score, confidence, signal density. No 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?

Three sentences: first states main action, second details process, third gives use case and output. Each sentence is valuable and front-loaded. 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?

With no output schema, the description explains return format (ranked list with metrics). Parameters are fully covered in schema. The description covers purpose, process, and use case. Could mention entity count limits, but overall adequate.

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 parameters are fully described. The description adds high-level context (e.g., first entity is 'subject') but does not provide additional semantic details 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 it compares AI visibility across multiple entities, probes each with ai_visibility_check, ranks results, and surfaces most/least recognized. It distinguishes from sibling tools like ai_visibility_check (single-entity) and compare_entities (generic) by focusing specifically on AI presence and ranking.

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?

Description gives clear context and an explicit use case ('competitive AI-marketing audits') with an example question. However, it does not explicitly state when not to use or mention alternative tools like ai_visibility_check for single-entity queries.

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 (readOnlyHint, idempotentHint), the description details fan-out to two services, bundlephobia timing (5-30s), graceful degradation, and sources_failed reporting. 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?

Well-structured and informative, but somewhat verbose. Could be tightened without losing clarity. Front-loaded with purpose and usage.

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 content (summary fields, advisories, links, versions) and edge cases (timeout, partial failure). Covers all necessary context.

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 description adds value: for 'package' it notes scoped packages are accepted; for 'version' it states default to latest. Slightly more detail would be ideal, but sufficient.

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 'Composite "should I add this npm package to my project" check in ONE call' and specifies it scans across deps.dev and bundlephobia, distinguishing it from sibling tools like scan_competitor_ai_presence or geocode.

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 guides when to use: 'Use whenever an agent asks "is X safe / popular / small"' and when not: 'NPM ecosystem only in v1; PyPI / Maven / Cargo / Go fall under deps.dev:version directly.' Also mentions partial failures and timing.

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 (readOnlyHint, idempotentHint, etc.), the description adds critical behavioral details: BGE-base-en embeddings, cosine similarity over 500-char overlapping windows, 200K char cap with truncation flag. 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.

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

The description is three sentences, each earning its place: first sentence states the core action, second explains when and why to use it, third adds technical details. No wasted words, front-loaded with purpose.

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?

For a tool with 3 parameters, no output schema, and comprehensive annotations, the description fully covers behavioral details, use cases, technical constraints, and pairing suggestions. It is complete and leaves no ambiguity.

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 value by specifying the max input length (~200K chars) for 'text', natural-language query examples for 'query', and the default and range for 'limit'.

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 performs semantic search inside a fetched record, with specific examples like SEC 10-K body or article. It distinguishes itself by explaining it returns passages with character offsets and similarity scores, which is unique among siblings.

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 tells when to use: when the record is too big for the prompt. It also mentions pairing with ask_pipeworx_grounded. However, it does not explicitly list alternatives or when not to use, slightly lowering the score.

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, and destructiveHint=false, so the safety profile is clear. The description adds that the tool returns a fetchable PNG URL and requires no interactive JS, which is consistent with annotations. It does not contradict annotations. The behavioral transparency is adequate given the annotation coverage.

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 extremely concise, with a single sentence that front-loads common usage patterns. Every phrase adds value, and there is no redundancy. The structure is efficient and easy to parse.

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 lacking an output schema, the description states that the tool returns a 'fetchable PNG URL', which is sufficient for understanding the return value. It covers the main inputs and outputs. The tool is simple, and the description provides enough context for correct usage, though it could mention that the URL is directly usable.

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%, so the description must compensate. It mentions 'style + coords + zoom + width/height' but does not elaborate on each parameter (e.g., marker, retina, attribution). The examples in the schema provide some context, but the description itself lacks detailed parameter semantics. This is a moderate compensation.

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: returns a MapTiler static-tile image URL for embedding. It uses specific verbs and resources ('returns a MapTiler static-tile image URL') and provides example use cases ('embed a map', 'map thumbnail', 'screenshot of map'). While sibling tools like 'tiles_json' might be related, the description sets it apart by focusing on static image URLs for embedding.

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 clear usage patterns ('embed a map', 'map thumbnail PNG', 'screenshot of map') but does not explicitly state when to avoid using this tool or mention alternatives like 'tiles_json' for interactive maps. It implies usage for static embedding scenarios, which is helpful but lacks exclusion criteria.

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 indicate idempotent, non-destructive, non-readonly. Description adds: requires OAuth, returns subscription id, SMS cap (10/day), webhook auto-disable after 10 failures, verification step for SMS. 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?

Well-structured: purpose first, then prerequisites, then type options, then delivery channels. Length is justified—every sentence adds value. Slightly verbose but efficient for a complex 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?

Complex tool with multiple types and delivery options; description covers prerequisites, type-specific params, delivery behaviors, limits, and return value. No output schema but declares subscription id return. Complete for agent selection and invocation.

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 100%, baseline 3. Description adds type-specific examples, delivery channel details (webhook signing, SMS verification, email). Significantly enriches param meaning.

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?

Clear verb+resource: 'Create a proactive monitoring subscription to a live-data event stream.' Returns subscription id. Distinguishes from siblings like list_subscriptions and unsubscribe.

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 prerequisite (Pipeworx OAuth account) and alternatives for each type and delivery channel. Implicitly not for one-off lookups—use siblings. Lacks explicit when-not-to-use but offers strong contextual 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 declare readOnly, openWorld, idempotent hints. Description adds valuable context: returns live catalog examples with tool+argument shapes, type of categories, and that it's drawn from thousands of tools. 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?

The description is thorough but somewhat lengthy. It is well-structured with a front-loaded purpose and detailed breakdown, though some repetitions could be trimmed. Still effective.

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 simple onboarding purpose, all necessary information is present: purpose, usage, parameter details, and what the response looks like. No output schema but description covers return format adequately.

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 topic parameter. The description adds more detail (list of topic values and the behavior when omitted), enhancing the schema info.

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 an onboarding entry point for Pipeworx, explaining it returns category-bucketed example questions. It distinguishes from siblings by noting it should be used first to learn what Pipeworx can do, with references to 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 when to use ('FIRST when you do not yet know what Pipeworx can do'), provides examples of queries, and outlines how to customize with optional topic parameter. Mentions alternatives indirectly via reference to meta-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, idempotentHint=true, and destructiveHint=false, so the agent knows this is a safe, read-only operation. The description adds context about returning TileJSON spec metadata but does not disclose additional behaviors such as rate limits, authentication requirements, or the full response format. Given the strong annotation coverage, 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.

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

The description consists of two concise sentences. The first sentence defines the tool's output, and the second provides usage guidance. Every sentence serves a clear purpose with no redundancy or filler. It is front-loaded with the core function.

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 (single parameter, extensive annotations, no output schema) and its niche audience (GIS integrators), the description covers the essential context: what the tool returns and when to use it. It could be improved by describing the 'tileset' parameter or the TileJSON schema, but the specialist audience may already know this. The example in the schema partially compensates.

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 only one parameter ('tileset') with 0% description coverage. The description mentions 'MapTiler tileset' but does not explain what valid values are, how to specify them, or any constraints (e.g., it only shows 'openstreetmap' in the example). With no schema description and minimal description guidance, the agent may struggle to invoke the tool correctly.

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 precisely states the tool returns TileJSON spec metadata (zoom range, bounds, layer schema) for a MapTiler tileset. It explicitly distinguishes the tool as a specialist tool for GIS integrators, contrasting with geocode/static_map_url for general users. This clearly communicates the tool's purpose and differentiates it from siblings like geocode and static_map_url.

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 clear guidance: use this tool when you need TileJSON metadata for GIS integration. It also advises that most users should use geocode/static_map_url instead, effectively telling the agent when not to use this tool. While it doesn't explicitly name other sibling tools for GIS tasks, the guidance is sufficient for decision-making.

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 that the row is deactivated (not deleted) and historical events remain available via recent_alerts. Annotations already indicate non-destructive and idempotent; description adds valuable detail 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, zero waste. Action is front-loaded and each sentence adds essential 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?

For a simple tool with one parameter, good annotations, and no output schema, the description fully covers the behavioral and usage context needed.

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 clear description of the id parameter. Description does not add new semantic information 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.

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

The description clearly states the action 'Cancel a subscription by id' and the resource 'subscription'. It distinguishes itself from sibling tools like subscribe and list_subscriptions.

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 mentions ownership enforcement ('you can only cancel your own subscriptions'), providing clear context for when to use. Does not explicitly state when not to use but implies it.

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, open-world, idempotent, and non-destructive behavior. The description adds value by detailing the output (verdict, actual value with citation, reasoning) and the two processing pipelines. It does not contradict annotations. Some aspects like rate limits or auth are omitted, but the description is sufficiently transparent given the annotation safety profile.

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 organized with clear sections: usage examples, purpose, two processing paths, and return values. It is slightly lengthy but every sentence adds useful information. Could be slightly more concise, but it's well-structured and front-loaded with 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 tool's complexity (2 parameters, no output schema), the description is quite complete. It explains the return format (verdict, value, citation, reasoning) despite no output schema. It covers both financial and non-financial claims. The annotations provide structural info, but the description compensates for the missing output schema well.

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 meaningful context beyond the schema: for 'tolerance_pct', it explains how it overrides implied tolerance and suggests values for hallucination detection. This enhances the parameter understanding beyond the schema's raw description.

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 explicitly states the tool's purpose as natural-language claim verification against authoritative sources, with specific examples (e.g., 'Is it true that...'). It clearly distinguishes between company financial claims and other factual claims, making its function unambiguous and distinct from sibling tools like ask_pipeworx_grounded.

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 directly says 'Use whenever the agent needs to check whether something a user said is factually correct.' It explains the two processing paths (financial vs. other claims) and mentions it replaces multiple sequential calls, providing clear context. However, it lacks explicit 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.
