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

Annotations already declare destructive, non-idempotent, non-read-only behavior. The description adds important context beyond annotations: user confirmation is required, server-side budget hard-limits still apply, and the result includes whether the change can be undone.

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 action and confirmation gate, then the operational constraint and return behavior. No wasted text.

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 destructive execution tool with an output schema and rich annotations, the description covers the key workflow gate, hard limits, and undoability signal. It leaves some failure-mode behavior unspecified, but is largely complete for correct invocation.

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?

With one parameter and 0% schema description coverage, the description partially compensates by explaining that the proposal comes from a propose_* tool. However, it does not explicitly say to pass the proposal_id returned by that tool or clarify identifier format.

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: execute a proposal produced by any propose_* tool. It distinguishes this tool from the propose_* family by framing it as the execution step after user confirmation.

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?

It explicitly says to use this after the user confirms a proposal from any propose_* tool, which is a clear workflow gate. It does not explicitly name undo_change as the reversal route, so the alternative is only implied by the mention of undoability.

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