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?

All necessary aspects covered: purpose, constraints (ownership), behavioral effect (deactivation), and link to related tool. No output schema needed for this simple parameter set. Annotations already cover safety.

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 clear description for the 'id' parameter. Description only redundantly says 'by id', adding no new semantic meaning beyond schema. Baseline 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?

Description clearly states 'Cancel a subscription by id' with specific verb and resource. It distinguishes from siblings by mentioning ownership enforcement and deactivation vs deletion, implicitly differentiating from '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?

Description provides clear context: ownership enforcement implies self-cancellation only. It explains the non-destructive effect and links to 'recent_alerts' for historical data. However, it lacks explicit when-not-to-use or alternative tool for full deletion.

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, openWorldHint, idempotentHint, and destructiveHint. The description adds significant behavioral context: it returns a verdict, structured form, actual value with citation, percent delta, and uses SEC EDGAR + XBRL. No contradictions with annotations; the description complements them 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 lengthy but front-loaded with query examples and a clear statement of purpose. Every sentence provides value, though it could be slightly more concise. Overall, it is well-structured.

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 a single parameter and no output schema, the description explains return types (verdict, structured form, citation, delta) and the underlying data source. This is complete enough for an agent to use 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 coverage is 100% for the single parameter 'claim', so baseline is 3. The description adds extra meaning by providing examples and specifying that claims should be natural-language and domain-specific (company-financial). This improves semantic 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 defines the tool as a natural-language claim verification against authoritative sources, with specific examples like 'Is it true that...' and 'fact check'. It explicitly states the domain (company-financial claims) and distinguishes from sibling tools by claiming 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?

The description says 'Use whenever the agent needs to check whether something a user said is factually correct', providing clear when-to-use guidance. It does not explicitly list when not to use or alternatives, but the domain specificity implies limitations. Sibling tools include similar ones, but no explicit exclusions are given.

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