Delivery: cancel announcement [3PL]

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

Description adds 'Irreversibly cancels' confirming destructiveHint=true, and discloses that regular accounts get 403/404, which goes beyond annotations. No contradiction with annotations.

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 concise sentences, no fluff, front-loaded with purpose. Every sentence adds value.

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?

Covers purpose, irreversibility, access restrictions. With annotations and high schema coverage, it is nearly complete. Minor gap: no description of the response upon successful cancellation (no output schema mentioned).

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 coverage is 100% so schema already describes each parameter. Description does not add new meaning beyond what's in the schema, so baseline score of 3 is appropriate.

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?

Clearly states it cancels a previously created announcement and references the creation tool. However, among siblings there is delivery_v1_cancel_announcement which is similar, and the description does not differentiate between them.

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?

Implies usage after creation of an announcement via delivery_create_announcement_3pl, and notes it returns 403/404 on regular seller accounts, implying it's for 3PL accounts. Does not explicitly state when not to use or compare to similar cancel tools.

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