request_approval

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

With no annotations, the description carries the full burden, and it only discloses that the result is a pending request. It doesn't say whether a notification is sent to the manager, whether calling twice creates duplicate requests, whether the request can be rescinded, or what permissions are needed, all of which matter for a mutating approval tool.

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 tight sentences with the mock caveat and action front-loaded, followed by the return value. Nothing is wasted, though the brevity comes at the cost of the parameter detail noted above.

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?

A four-parameter mutation tool with no annotations, no output schema, and 0% schema coverage demands far more than two sentences. Missing side-effect disclosure, parameter meanings, and sequencing relative to sibling approval tools leave the definition well short of what an agent needs to invoke it reliably.

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 explain the four parameters, but it only loosely implies manager_id ('the claimant's manager') and item_id ('one item'). claim_id is never mentioned, and reason is completely unaddressed, leaving half the inputs opaque.

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?

States a specific verb and resource: asking the claimant's manager to approve one item. It clearly distinguishes this from read-only siblings like get_claim or find_approval_memo, though it doesn't explicitly contrast with the closest sibling draft_decision. The '(Mock)' marker also signals this is a demo-environment operation.

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 call this versus draft_decision or find_approval_memo, and no stated preconditions (must a claim exist, must a memo be found first?). The only implied context is that an approval flow exists, which an agent has to infer from the sibling names.

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