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

Annotations already cover the safety profile (readOnlyHint false, idempotent, non-destructive, openWorld). The description adds genuinely non-schema context: it is a paid x402 call costing 0.05 USDC with an X-Bazaar-Key header, plus a free sample report URL — exactly the kind of auth/payment prerequisite an agent must know before invoking. It stops short of describing the report's output structure beyond the six check names.

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 dense sentences that front-load the core purpose and the list of checks, then close with payment terms and the sample link. No filler, though the pricing/URL tail pushes it slightly past the essential purpose statement.

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 multi-check composite with no output schema, the description names all six constituent audits so an agent knows exactly what is evaluated, and discloses cost and payment mechanics. It could be fuller on how results are returned (per-check sections vs aggregate score), which is the only notable gap.

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?

Only one optional parameter (vm_size) and its schema description coverage is 100%. The description adds no meaning beyond 'Target VM size preset', but with complete schema coverage the baseline of 3 is appropriate and the burden is already met by the schema.

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 and resource ('Composite 6-check DevOps infrastructure audit') and then enumerates exactly what it chains: Dockerfile, fly.toml cost guard, Kubernetes pod security, Terraform HCL, Nginx TLS, and GitHub Actions pinning. An agent can distinguish this aggregate audit from the single-purpose siblings dockerfile_lint and fly_toml_lint without opening a schema.

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 composite nature and enumeration imply you call this when you want all six checks in one pass rather than the individual lint siblings, but that routing choice is never stated. No when-not conditions, prerequisites, or guidance about when the individual tools are preferable. The free sample link is a useful tangent but is not usage guidance.

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