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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds no behavioral context at all - not pagination, not ordering, not what the actions collection contains, not whether an unknown id errors or returns empty.

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?

Short, but the first two sentences are identical copies of the same path string - pure waste. The only non-redundant token is the operation ID, which is metadata rather than meaning.

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 no output schema, 0% schema coverage, a nested free-form 'query' object, and no annotations gaps filled by the description, an agent has essentially nothing to work with beyond the URL. It cannot tell what the response shape is, how to filter actions, or what to expect for a missing approval.

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 0%, so the description must compensate, and it largely does not. The ':id' path fragment hints that the required id parameter identifies an approval, but the optional 'query' object (which supports arbitrary properties) is completely unexplained.

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 text is a verbatim restatement of the endpoint path and duplicates the title, adding nothing an agent could not read from the name. It implies fetching the action list for a given approval via 'GET /api/approvals/:id/actions', but it never says what an 'action' is or how this differs from the sibling get_approvals_by_id.

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?

No when-to-use, when-not-to-use, or alternative is given. The only actionable pointer is 'describe_operation provides native request schemas', which is a schema-discovery tip rather than invocation guidance. Nothing tells the agent how this relates to get_approvals_by_id or get_approvals_progress.

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