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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered elsewhere. The description adds the concrete endpoint (GET /depot/details) and a hint at the returned content (per-part quantities), but says nothing about auth needs, rate limits, or pagination.

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?

Two short sentences with no filler; the core purpose and returned content are front-loaded, and the endpoint is a compact trailer.

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 read-only getter with full parameter coverage and annotations carrying the safety profile, the description is nearly sufficient, and its mention of per-part quantities compensates for the absence of an output schema. Only minor gaps remain around error cases and auth.

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% and the single id parameter is fully documented there, including its GUID source tool. The description only restates 'by id' and adds no format or constraint detail beyond the schema, so the 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?

The description names a specific verb and resource ('get depot') and states the payload contents ('quantity of each part it holds'), which an agent can act on without opening the schema. It does not explicitly contrast itself with the closest sibling synchroteam_list_depots, so it falls short of the top band.

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 phrase 'by id' implies the single-record lookup use case, but the description gives no explicit when-to-use guidance or naming of the alternative list_depots tool for broader queries. Usage is only inferable, which matches the minimum-viable band.

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