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

Annotations cover the mutation profile (readOnlyHint=false, not idempotent, not destructive), and the description adds latency expectations (about 2, occasionally up to 4 minutes) plus the auto-approval behavior, which is genuinely useful beyond the structured fields. It does not mention duplicate-order or idempotency risks, which would be the remaining gap.

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 action and the approval/timing details are front-loaded in the first two sentences. The trailing sentence explaining Kilotest's purpose and result hierarchy is largely domain context that is already available elsewhere and slightly dilutes the tool-specific content.

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?

With an output schema present, the description need not explain return values, and it does not need to compensate for parameter gaps given full schema coverage. It is nearly complete; the only omission is explicit routing guidance against the requestRetest and orderNewTest siblings.

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%, so jobID, reason, and timeStamp are already fully documented with formats and constraints. The description adds no parameter-level meaning beyond the schema, so the baseline of 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?

The description states a specific verb (order a retest of a page) and resource, and distinguishes the auto-approval path from the manual one. It does not explicitly name the sibling requestRetest, so the differentiation from that sibling is implied rather than stated.

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?

It gives the condition for using this tool implicitly ('instead of waiting for manual approval', 'immediately and automatically approved'), which implies it is the fast path. It never names the alternative tool or states when this tool should NOT be used, leaving the routing inference to the agent.

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