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

Annotations already flag destructiveHint=true and openWorldHint=true, but the description adds genuinely new context: the action is performed as the token's user and Talenox may notify the employee. It does not say whether a rejection can be reverted or whether a reason is recorded, which is the only meaningful omission for a destructive write.

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?

Three short sentences, front-loaded with the operation class and effect, then the safety protocol. No redundant restatement of the title or schema.

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 one-parameter destructive mutation with no output schema, the definition covers operation class, side effects, and the required read-and-confirm protocol. Only reversibility/undo behavior and reason handling are left unstated.

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 100% — the single 'id' parameter is documented as 'The leave application id.' The description adds no further semantics (e.g. where to obtain the id beyond the referenced get tool), so baseline 3 applies.

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 ('reject a leave application') and prefixes it with 'WRITE' to mark the operation class. The mirror sibling talenox_approve_leave_application is unambiguously distinguished by the verb alone.

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?

Explicitly prescribes the prerequisite flow: read the application with talenox_get_leave_application first, then confirm with the user before rejecting. It names a concrete alternative tool and the condition under which it must run first.

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