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

No annotations are supplied, so the description carries the full disclosure burden. It does add one genuinely useful behavioral fact beyond the name: the output is 'a copy-paste prompt pack with examples' rather than finished copy, which shapes how an agent should present results. It says nothing about length, format, iteration behavior, or whether the pack is tailored to the query.

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 sentences, front-loaded with the resource name, so it is easy to scan. However, 'production-ready' and 'you can run today' are marketing filler that consume space without informing an agent's decision, and the one concrete fact (prompt pack with examples) is buried at the end.

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 simple (one optional param, no output schema), so the description does not need much. It partially covers the key unknown by saying the output is a prompt pack, but leaves the actual deliverable structure and the role of the query unspecified, which is thin for a tool whose only differentiator among hundreds of siblings is its output shape.

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 it. The description never mentions the query at all, so it adds no meaning about how scoping the analysis changes the returned prompt pack. Baseline 3 is appropriate when 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 description names the resource (an xhs viral copywriter) and an audience (marketing and operations leaders), but the verb is fuzzy: it never says whether the tool writes copy, or returns a reusable prompt pack. 'Get a structured, repeatable workflow' suggests the deliverable is a template pack, which is unusual enough that it needed to be stated plainly. With dozens of near-identical xhs/viral siblings in the catalog, nothing here reliably separates it from viral-copywriter, xhs-hook-master, or baokuan-copywriter.

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?

There is no when-to-use or when-not-to-use guidance and no alternative tool is named, despite the catalog containing many close siblings (viral-copywriter, xhs-adcopy-kit, xhs-hook-master). The only usage cue is the audience label 'marketing and operations leaders', which does not tell an agent which task should route here.

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