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

Annotations already declare destructiveHint=true, idempotentHint=false and openWorldHint=true, so the safety profile is covered. The description adds real value beyond that: it names the external systems written to (Google, Meta), the required confirm flag, and the permission requirement for the acting user.

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 action and its constraints front-loaded and no filler. However, given 33 optional parameters it is arguably under-specified rather than optimally sized.

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, open-world tool with 33 parameters and zero schema descriptions, the description does not show how to identify which proposal is being executed or what dry_run does. The presence of an output schema covers return values, but the input-side guidance is far from sufficient.

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?

33 parameters, none required, and 0% schema description coverage, yet the description only clarifies one (confirm=true). It leaves the identity/selection parameters (action_id, name, scope, platform, client_id, rule_id) and the dry_run flag entirely unexplained, which is a substantial gap.

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 (execute) and resource (a pending pause or budget proposal), and names the two downstream platforms it writes to. It clearly pairs with the sibling propose_* tools, though it never names them explicitly.

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?

"Pending ... proposal" plus "Requires confirm=true and a user who can mutate data" communicates the precondition and the gate for calling it. There is no explicit when-not guidance or named alternative, but the context is clear enough to act on.

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