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

Annotations already declare readOnly, idempotent, non-destructive, closed-world, so the safety profile is covered. The only added value is the pointer to describe_operation for native request schemas, which is a minor navigational hint rather than behavioral disclosure about the approval object, its states, or fields.

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 nearly identical sentences followed by an operation ID and a schema pointer; the duplication wastes the opening position that should carry the substantive explanation.

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 nested-object, 0%-documented-parameter tool with no output schema, the description provides no information about the returned approval shape, required id format, or errors. Only the describe_operation pointer gives the agent a path forward.

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% across 2 parameters, and the description only implies that 'id' is a path segment via the ':id' template. It says nothing about the arbitrary additionalProperties 'query' object, so it fails to compensate for the undocumented schema.

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 is essentially the HTTP method and path restated twice, which mirrors the tool name and title rather than explaining what an approval record is or what the response contains. It does distinguish the '/:id' single-resource form from list endpoints such as get_approvals_e70dd9642ffd2dec231cef2d, but only implicitly through the path template.

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 guidance on when to use this vs the many sibling approvals endpoints (get_approvals_by_id_actions, get_approvals_progress, get_approvals_workflows_by_id). No prerequisites, no mention of what id value is expected.

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