create_settings_jobs_by_job_id_cancel

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

Annotations already cover read-only and idempotency, and the description adds no behavioral context beyond repeating the endpoint and path parameter. It does not mention what happens to a running job, whether cancellation is reversible, or whether there are any side effects.

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?

The core purpose is front-loaded in a single clear sentence. The additional endpoint and Args lines are mostly redundant with the schema, but the overall length is minimal and scannable.

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 single-parameter endpoint with an output schema, the description is minimally sufficient to invoke it. However, it omits context such as when cancellation is valid, whether the job must be currently running, and any expected failure modes.

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 description coverage is 0%, so the description must compensate. It does add one useful semantic detail by labeling job_id as a path parameter, but it does not provide any format, source, or relationship to other job-related endpoints.

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 ('Cancel') and resource ('a specific job'), making the operation unmistakable. The sibling set includes run and schedule variants for jobs, and 'cancel' clearly distinguishes this tool from 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?

No guidance is given for when to use this tool versus alternatives such as run or schedule. The description simply says what it does, without explaining when cancellation is appropriate or any prerequisites.

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