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

Annotations already declare readOnlyHint=true, so safety is covered, but the description adds essentially no behavioral context beyond that: nothing about whether statuses are terminal, whether polling is expected, or whether the id is guaranteed to resolve. For a status-checking tool the polling/terminal-state behavior is the most valuable thing it could disclose.

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?

One short, front-loaded sentence with no filler. It earns its place but is arguably too clipped for the information an agent needs, so it stops 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?

For a single-parameter read tool with annotations covering safety and no output schema, the description is minimally adequate: it says what is returned conceptually (the request's status) and where the id comes from. It omits what a status value actually looks like (pending/succeeded/failed) and any polling guidance, which leaves the agent guessing about the response even though no output schema exists to compensate.

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 0% and the single `id` parameter is typed only as a bare string in the schema, so the description's 'by its id' and the link to the `request` tool do add real meaning: the id is the handle returned by the request-submission flow. It still does not say whether the id is required to be exact, or what happens with an unknown id.

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 the resource (a request) and the operation (where it stands = retrieve status) and explicitly ties it back to the `request` sibling, which is the tool that creates one. The phrasing 'where ... stands' is indirect rather than a clean verb like 'Returns the status of', but an agent can still distinguish this from siblings such as `request` or `thread_read`.

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?

Usage is implied: call this after submitting via `request` to check on that submission, and the reference to `request` supplies that pairing. There is no explicit when-to-use trigger, no when-not, and no guidance about polling or how long to wait.

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