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

No annotations are supplied, so the description carries the full behavioral burden, and it largely fails: it does not say what is returned, whether input complaints are modified or only inspected, or whether any external system is touched. The phrase "delivered as a copy-paste prompt pack with examples" hints at a template-delivery behavior, but that is the only concrete signal and it is confusing rather than clarifying.

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?

Only two sentences, but nearly all of it is positioning copy ("production-ready", "leaders", "run today") rather than capability. The front-loaded sentence should state the operation, not the sales pitch.

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 no annotations and no output schema, the description is the only source of behavioral information, and it omits the return shape and the actual checking logic. A caller cannot predict what comes back or what a successful invocation produces.

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 `query` parameter with 100% schema description coverage, so the schema already explains its purpose. The description adds nothing about how a query scopes the analysis, which is the one detail that would have helped; baseline 3 applies where the schema does the work.

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 text restates the name ("complaint check tool") and wraps it in marketing language ("production-ready ... system for marketing and operations leaders"), but never says what the tool actually does with a complaint — check it for what? compliance, tone, completeness, legal risk? With eight sibling complaint-* tools (audit, sort, audit, gen, polish, reply, rewrite, summary), this ambiguity is fatal for selection.

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?

"Get a structured, repeatable workflow you can run today" is promotional framing, not guidance. There is no statement of when to pick this over complaint-audit-tool, complaint-sort-tool, or complaint-check-tool's own siblings, and no prerequisites or exclusions.

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