deployment_readiness_check

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 does disclose one important behavioral trait: the tool returns a "structured prompt" rather than executing a check itself, implying a read-only, non-mutating operation. However, it omits permissions, whether it inspects live systems, and any side effects or rate limits.

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 tightly written sentences: the first states the action, the second the return. Zero filler and the essential purpose is front-loaded.

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?

There is no output schema, and the description compensates by characterizing the return (a structured prompt assessing risk, rollback, observability, and go/no-go gates). With only one required parameter and well-documented optional ones, an agent has enough to call it correctly; only the absence of precondition/permission detail keeps it from a 5.

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 80%, so the schema already documents changeSummary, blastRadius, observability, and rollbackMechanism. The description adds no per-parameter meaning beyond what the schema supplies (the enum riskLevel is self-explanatory), so the baseline of 3 is correct.

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 gives a specific verb+resource: "Perform a pre-deployment readiness check," and the second sentence enumerates what the check covers (risk, rollback, observability, go/no-go gates). This is clear. It does not name or contrast any sibling tool, so it falls short of 5, but no sibling (review_cicd_pipeline, review_infra_config) plainly overlaps in function.

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?

"Pre-deployment" implies the usage window, but there is no explicit when-to-use statement, no prerequisites, and no guidance on when a different tool (e.g. review_cicd_pipeline, review_infra_config) would be a better fit. Usage is implied rather than stated.

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