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

With no annotations, the description still conveys read semantics through 'Get' and 'current state,' and it discloses the return contents at a high level. It also explains a specific error-recovery behavior involving create_release, though it does not explicitly state read-only safety, permissions, or rate limits.

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 tightly written sentences with no waste. The core purpose is front-loaded, and the second sentence adds a specific operational scenario rather than repeating the schema.

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 read tool with no output schema, the description explains what is returned and when to use it. Required parameter details are fully covered by the rich schema, so the description is complete enough for correct invocation.

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%, so the schema already documents all five parameters thoroughly, including track_id and the account/app/developer ids. The description adds only that lookup is by track_id and does not supplement the remaining parameters.

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 gives a specific verb and resource: 'Get one release track's current state by track_id.' It also states what the result includes (every release with release_id, name, status, lifecycle state), which distinguishes it from get_release and list_tracks.

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?

It gives a clear use case: finding an existing draft release's id after create_release refuses a second draft. It does not explicitly name alternatives or exclusions, but the triggering context is concrete and useful.

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