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

No annotations are provided, so the description carries the full burden. It discloses that the operation is idempotent by action_id and safe to retry, which is valuable behavioral context for a mutation tool. It does not detail side effects or reversibility, but the retry-safety and explicit confirmation guard meaningfully reduce the agent's uncertainty.

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 contain the essential information: what the tool does, its idempotency for safe retries, and the exact triggering condition. There is no filler and the most important usage constraint is clearly stated.

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 mutation tool with no annotations and no output schema, the description covers the key invocation concerns: what to pass, the source of action_id, the confirmation requirement, and retry safety. It does not describe the return value or error behavior, but those are less critical for selecting and safely invoking the tool correctly.

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?

The schema already documents both parameters with 100% coverage, so the baseline is 3. The description adds value by specifying that action_id comes from get_weekly_plan and that confirm is a guard against accidental dispatch, reinforcing the schema's meaning beyond raw field definitions.

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 ('execute'), a clear resource ('specific action from the merchant's weekly plan'), and gives concrete examples such as publish bundle, run mining job, and archive rule. It is easily distinguished from sibling tools like get_weekly_plan, which is about reading the plan rather than acting on it.

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 tells the agent when to use it: AFTER the merchant confirms which action from get_weekly_plan they want to run. It also gives a direct exclusion: 'do not call preemptively.' This is clear, actionable guidance with no ambiguity.

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