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

The description adds real behavioral context beyond annotations: it is a paid call (0.05 USDC via x402 / X-Bazaar-Key) and a sample report exists, which annotations alone would not reveal. That is consistent with readOnlyHint=false and destructiveHint=false. The major undisclosed behavior is the target: with zero required parameters, it never explains what repo is audited or how the target is selected.

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 compact blocks: a bracketed price/auth tag followed by one dense sentence enumerating the checks, then a sample link. Front-loaded and nearly waste-free, though the pricing tag occupies prime position ahead of what the tool actually does.

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 paid composite with no output schema and no required inputs, the description covers what is checked and what it costs, but omits how the audited repository is identified, what the report structure/verdict looks like, and what a failed payment or partial scan produces. Those are material gaps an agent needs before invoking a $0.05 call.

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?

There is a single optional parameter with 100% schema description coverage (bom_format: CycloneDX or SPDX), so the schema already carries the semantics and baseline 3 applies. The description does not reference bom_format or explain whether the choice affects the audit output, and additionalProperties=true leaves the real targeting inputs entirely unexplained.

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 names a specific composite artifact (6-check supply-chain audit) and enumerates exactly what is chained: CycloneDX SBOM, package.json, pyproject.toml, Renovate/Dependabot, env secret-leak scan, and SemVer compatibility. That makes the scope obvious and separable from the other suite_* siblings. It stops short of stating explicitly how it differs from overlapping single-purpose siblings like semver_compat_check or suite_cloud_and_container_ops.

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?

Usage is implied rather than stated: an agent can infer 'use this for a full repo hygiene audit' from the check list, and the free sample report link gives a try-before-buy path. However, there is no explicit when-to-use/when-not guidance versus the single-check siblings or the other suites, and no prerequisites for obtaining the X-Bazaar-Key or paying.

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