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 deep context: 'text' is a previously fetched document, 'query' is natural-language with examples, 'limit' defaults and range. Adds meaning 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 'Semantic search INSIDE a fetched record' and explains the use case (large records). It distinguishes itself from siblings like ask_pipeworx_grounded by describing how they pair together.

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 when the record is too big to cram into the prompt' and contrasts with 'ask_pipeworx_grounded' for grounding. Provides clear when-to-use and pairing 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 are consistent (idempotentHint true, etc.). The description adds beyond annotations: requires OAuth account, returns subscription id, explains type-specific behaviors, delivery limits (SMS 10/day), webhook auto-disable, and HMAC signing. 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 dense but well-structured: purpose first, then prerequisites, then types, then delivery. All sentences add value, though it could be slightly more concise in delivery details.

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 parameters with nested objects, no output schema), the description is thorough: covers return value, all types, delivery channels, limitations, and verification steps. 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 significant meaning: examples for each type, delivery channel details (SMS verification, webhook signature), and required fields for clinical_trial. This goes well beyond the schema's brief 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 explicitly states the verb and resource: 'Create a proactive monitoring subscription to a live-data event stream.' It distinguishes from sibling tools like 'unsubscribe' and 'list_subscriptions' by focusing on creation.

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 context for when to use the tool (proactive monitoring) and prerequisites (Pipeworx OAuth account). It details supported types and delivery channels, but does not explicitly state when not to use or compare to alternatives like 'recent_alerts'.

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 as true and destructiveHint false. The description adds behavioral context such as returning 'category-bucketed example questions with exact tool + argument shape' and that it draws from a live catalog. This enriches understanding beyond the annotations.

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

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

The description is moderately long but front-loaded with common question phrases ('What can I ask Pipeworx?'). It is well-structured, first stating the use case, then listing categories, then usage instructions. Each sentence adds value; however, it could be slightly more 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?

Given the tool's role as an onboarding entry point with optional topic filtering and no output schema, the description is highly complete. It explains the return format (category-bucketed examples with tool+argument shapes), when to call it (first time), and how to use the optional parameter. It adequately 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% with one optional parameter 'topic' described as 'Optional focus area...'. The description adds value by explaining that omitting the parameter gives a 'cross-category spread' and lists possible values ('finance, pharma, ...'). This provides clarity beyond the schema's brief 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 clearly states that the tool serves as an onboarding entry point, returning category-bucketed example questions. It uses specific verbs like 'returns category-bucketed example questions' and distinguishes itself from siblings like 'discover_tools' by being the first call for new users.

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 advises to use this tool 'FIRST when you do not yet know what Pipeworx can do for you'. It also explains when to use the optional topic parameter ('to focus') and lists example scenarios like 'getting started'. It does not provide explicit when-not-to-use but the context is 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?

The description adds behavioral context beyond annotations: it clarifies that the row is deactivated (not deleted) so historical events remain available via 'recent_alerts', and it enforces ownership. 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?

Three concise sentences front-loaded with the main action. Each sentence provides new information: action, ownership, and side effect. 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?

Given a single parameter, no output schema, and clear annotations, the description covers purpose, behavior, and side effects comprehensively. It tells the agent everything needed to use the tool 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?

The schema already describes the 'id' parameter fully (uuid tied to subscribe). The description adds no new semantic meaning beyond reiterating 'by id'. With 100% schema coverage, 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 the action 'Cancel a subscription by id' and the resource (subscription). It distinguishes from sibling 'subscribe' by specifying cancellation and ownership enforcement.

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 when to use the tool (to cancel a subscription) and states ownership constraints. However, it does not explicitly mention when not to use it or provide alternative tools, though the sibling list includes 'subscribe' and 'list_subscriptions'.

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. The description adds valuable behavioral context: the tool returns a verdict with five enum values, extracted structured form, actual value with citation, and percent delta, and specifies the data source (SEC EDGAR + XBRL). The description is consistent with annotations and adds detail beyond them.

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: it opens with a clear statement of purpose, follows with usage guidance, then details scope, output, and added value. While slightly long, every sentence adds relevant information. It is front-loaded and avoids 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?

For a single-parameter tool with annotations and no output schema, the description is quite complete. It explains input, output format, domain (company-financial claims), and the advantage over multiple sequential calls. It could mention that only US public companies are supported, but the v1 notice implies limited 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?

Schema description coverage is 100% (the 'claim' parameter is described in the input schema). The description provides examples of the parameter's natural-language format but does not add significant meaning beyond the schema. With full schema coverage, a 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 tool's purpose: natural-language claim verification for company-financial claims using SEC EDGAR + XBRL. It provides specific verbs ('verify', 'fact check') and distinguishes itself by replacing multiple sequential calls, setting it apart from siblings like ask_pipeworx or deep_research.

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 whenever the agent needs to check whether something a user said is factually correct' and limits the domain to company-financial claims. It does not provide explicit when-not-to-use guidance, but the domain restriction and mention of replacing 4-6 calls imply appropriate context.

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