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

The description discloses key behaviors: it returns the latest snapshot, includes stale flags based on freshness SLA, and provides signed receipts. However, with no annotations, it lacks details on error handling, authentication, or how outdated slugs are handled, leaving some behavioral ambiguity.

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 a single, well-structured sentence that first states the purpose and output components, then provides a concrete usage example. Every part is essential and there is no redundant 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 simple input schema (one required parameter) and no output schema, the description fairly captures what the tool returns. It lists all major output components and includes a usage hint. Minor gaps like missing return format or error cases are acceptable for a straightforward 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?

The schema has one required parameter (slug) with no description (0% coverage). The description offers an example ('Try slug 'govcon-demo'') which hints at slug being a feed identifier, but does not fully define its format or acceptable values, providing only partial semantic 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?

The description clearly states it returns 'the latest verification snapshot of a minted feed' and lists specific components (per-record status, as-of date, stale flags, signed receipts). This distinguishes it from siblings like verify_receipt, which focus on individual records.

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?

Although the description includes an example slug ('govcon-demo') implying a use case, it does not explicitly state when to use this tool versus the sibling tools (verify_receipt, verify_record, verify_subject). Usage context is implied but not clearly delineated.

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