Annotations already declare readOnlyHint, idempotentHint, and non-destructive. The description adds value by specifying that it returns category-bucketed example questions with exact tool+argument shapes, and that it uses a live catalog. 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 front-loaded with purpose and includes multiple alternative phrasings, which is helpful for agent understanding. While slightly verbose, every sentence adds value and it remains focused.

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 onboarding tool, the description covers purpose, usage, parameters, and return value (category-bucketed examples). Without an output schema, it adequately describes the result. 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 optional parameter. The description adds meaning by explaining that omitting topic gives full spread and passing topic focuses on a category, plus listing example values. This enriches understanding beyond the schema.

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

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

The description clearly identifies the tool as an onboarding entry point that returns example questions about Pipeworx capabilities. It explicitly distinguishes itself from sibling tools like ask_pipeworx and discover_tools by advising to use this first when unsure what Pipeworx can do.

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 usage context: use when you do not yet know what Pipeworx can do or to learn how to call meta-tools. It does not explicitly list when not to use, but the context of being a first step implies 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?

The description adds meaningful behavioral context beyond annotations: ownership enforcement and deactivation (not deletion) with historical events remaining via recent_alerts. Annotations already indicate non-destructive, idempotent, and open-world behavior, but the description provides specific context.

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

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

The description is extremely concise at two sentences, front-loading the purpose ('Cancel a subscription by id') followed by key behavioral notes. Every sentence provides essential information with no waste.

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 (one parameter, no output schema, good annotations), the description fully covers the necessary context: what it does, ownership constraints, deactivation behavior, and linkage to recent_alerts for history.

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% (parameter 'id' is described as 'Subscription id (uuid) returned by subscribe'). The description adds no further semantics beyond stating 'by id', which is already clear from 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 tool cancels a subscription by id, with the verb 'cancel' and resource 'subscription'. It distinguishes from related tools like subscribe and list_subscriptions implicitly by being the reverse operation, but does not explicitly compare to sibling 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 implies usage for canceling subscriptions but does not provide explicit guidance on when to use this tool versus alternatives like subscribe or list_subscriptions. Ownership enforcement is mentioned but no when-not conditions or recommendations for 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 provide readOnlyHint, idempotentHint, etc. Description adds significant context: uses SEC EDGAR + XBRL, returns verdict with citation and delta, and replaces multiple sequential calls. 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?

Front-loaded with purpose and examples. Every sentence is informative, but the description is slightly long; however, the complexity justifies the length.

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 the return structure (verdict, extracted form, actual value, citation, delta). It covers supported claim types and sources, making it 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 coverage is 100% with a clear description for the single 'claim' parameter. Description adds minimal extra value beyond the schema, so 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 tool verifies natural-language claims against authoritative sources, with specific examples like 'Is it true that...' and 'fact check'. It distinguishes from siblings by noting it replaces multiple sequential calls.

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

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

Explicitly states 'Use whenever the agent needs to check whether something a user said is factually correct'. It specifies supported claims (company-financial for US public companies) but does not explicitly exclude other types.

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