approve_change

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

With no annotations, the description carries the burden. It discloses the side effect (moving to Implement) and a known failure condition (Change Model governance), which is useful. However, it does not mention permissions, reversibility, or what happens if the approval is already processed, leaving gaps for a mutation 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 sentences with no filler. The primary action is front-loaded, and the critical failure note is appended succinctly. Every word earns its place.

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 simple tool with three parameters and no output schema, the description covers the core action and a key risk. It could be more explicit about prerequisites (e.g., change must be in pending approval status) but the 'pending approval record' phrasing implies this condition. Overall, it is mostly complete.

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 67% (change_id and approver_id have descriptions; approval_comments does not). The description does not add any parameter-specific meaning beyond the schema, so it sits at the baseline for moderate coverage.

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 ('Approve') and resource ('a change request's pending approval record') and includes the outcome ('move the change to Implement'). This clearly distinguishes it from siblings like reject_change (opposite action) and submit_change_for_approval (submission step).

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?

The description implies the use case (approving a pending approval) but does not explicitly contrast with alternatives such as reject_change or explain when to avoid this tool. The governance failure note is a caution, not a usage guideline, and no exclusions are provided.

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