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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so the safety profile is covered. The description adds that the record is returned complete and 'as published' (no summarization), which is useful, but it says nothing about behavior on an invalid/unknown id or lookup failure.

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 core action is front-loaded in the first clause, and the second sentence gives the id source. The long comma-list of record contents is a bit dense and overlaps the output schema, keeping it short of a 5.

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 one fully described required parameter, an output schema, and annotations covering the safety profile, the description is sufficient to invoke correctly. Only missing element is failure/not-found behavior for a bad id.

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% and the schema supplies a concrete example id, so the parameter is fully documented. The description adds only the provenance hint that the id comes from another tool's result, which is marginal but not zero value; baseline 3 applies.

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?

States a specific verb ('Get') and resource ('one apiwatch record') plus the scope 'in full, as published', and enumerates the payload (changes, remediation, search strings, uncovered ids, applicability, vendor source, review date). That distinguishes it clearly from list_upcoming, search_changes and mcp_server_changes, which are plural or change-oriented.

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?

'Use an id from another tool's result' implies the intended workflow (search/list first, then fetch details) but never names which sibling produces such ids or states when not to use this tool. Usage is inferable rather than spelled out.

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