Time Delete Approval

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

Annotations already declare destructiveHint=true and readOnlyHint=false, so the safety profile is covered, but the description adds real value: the deletion is limited to "pending" records and the confirm=True precondition is disclosed. It still omits what happens on failure (e.g., non-pending record) or whether deletion is reversible, keeping it from a 5.

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?

A single tight sentence with the verb front-loaded and the constraint in a parenthetical; every clause earns its place with no redundancy.

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?

An output schema exists, so return values need no explanation, and the description covers the two things an agent most needs for a destructive operation: the pending-only scope and the confirm flag. It could still state irreversibility or error behavior, but nothing essential for correct invocation is missing.

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% for both parameters, so the description must compensate. It does document the critical confirm=True requirement, which is not in the schema, but says nothing about the required approval_id (format, accepted integer-or-string types), leaving half the parameters 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 description states a specific verb and resource ("Delete ... approval record") and narrows scope with "pending", so an agent knows it targets only pending approvals. However, it does not name or distinguish itself from nearby approval siblings (time_list_approvals, time_create_approval, time_update_time_approval_status), so it falls short of a 5.

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?

There is no when-to-use or when-not-to-use guidance and no named alternatives; the only guidance offered ("requires confirm=True") is a parameter precondition rather than routing advice. Usage is only weakly implied by the verb.

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