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

With no annotations supplied, the description carries the full behavioral burden and fails to meet it. It does not disclose whether the tool only analyzes text, what permissions or inputs it requires, whether the result is a report, a rewritten text, or a prompt pack, or what happens when the optional query is omitted. The "copy-paste prompt pack" claim actively confuses the expected behavior of a callable tool.

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 both are marketing copy rather than specification; every phrase ("production-ready", "repeatable workflow you can run today", "copy-paste prompt pack") could be deleted without losing operational information. It is short but not front-loaded with anything an agent can act on.

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?

The tool is structurally simple (one optional parameter, no output schema, no annotations), so a brief description could be complete — but this one omits the essentials: what input is checked, what the response contains, and how it differs from the numerous sibling avoidance/check tools. An agent could not confidently decide to call it or predict its result from this text.

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% and the single optional `query` parameter is documented in the schema as scoping the analysis. The description adds no meaning about what scoping does, what text gets checked, or what a call without a query returns, so it neither compensates nor detracts — baseline 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 first clause restates the tool name ("forbidden word check") and the rest is promotional framing ("production-ready", "for marketing and operations leaders") rather than a statement of the operation. It never says what the tool actually does with the input or produces as output, and the phrase "delivered as a copy-paste prompt pack with examples" muddies whether this is a checker or a content deliverable.

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?

No when-to-use, when-not-to-use, or alternative is named, despite many plausible siblings in the catalog (xhs-avoid-kit, dy-avoid-kit, sph-avoid-kit, zh-avoid-kit, gzh-avoid-kit) that appear to cover the same avoidance/forbidden-word territory. The only contextual hint is an audience label ("marketing and operations leaders"), which does not tell an agent when to select this tool over those.

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