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

Annotations already declare readOnlyHint=false and destructiveHint=false, so the write-but-safe profile is covered. The description adds the return content (job ID and result) but does not disclose whether the test job consumes quota/cost or has side effects on the pipeline state.

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, front-loaded with the action and goal, and the second sentence usefully covers the return value. Nothing extraneous.

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 two-parameter, non-destructive mutation tool with full schema coverage and no output schema, the description gives the essential action, onboarding position, and a return summary. It is nearly complete, missing only side-effect/cost context.

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 description coverage is 100% and both parameters (kernelId, deviceId) are already documented in the schema, including the optionality of deviceId. The description adds no syntax or format detail beyond the schema, so the baseline 3 applies.

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 (Submit) and resource (test job) plus the pipeline-verification goal, and anchors it as 'Step 4 of onboarding', which distinguishes it from get_job/list_jobs. It does not explicitly contrast with the other setup_* siblings, but the purpose is clear.

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?

The '(Step 4 of onboarding)' note implies when in the sequence this is called, giving usable context. However, it never states prerequisites or when NOT to use it versus setup_validate/setup_detect/setup_status, leaving the agent to infer.

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