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

No annotations are supplied, so the description carries the full burden. It hints at the deliverable form ("copy-paste prompt pack with examples"), which is the one real signal, but it says nothing about whether the call is read-only, whether it requires account or platform context, what volume/length of output to expect, or what happens with an empty 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 short sentences with no bloat, but nearly all of the text is benefit language ("production-ready", "you can run today") rather than specification. It is brief without being informative, so length is not the problem — content density is.

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 must carry the whole definition, and it omits the single most important fact: which platform/content domain "zh" denotes. In a sibling set of dozens of platform-prefixed kits, an agent cannot confidently select or invoke this tool from what is written.

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` param is already documented as scoping the analysis, so the baseline of 3 applies. The description adds no meaning about how the query affects the generated kit or what a scoped versus unscoped result looks like.

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 restates the name ("script kit") and wraps it in promotional language ("production-ready", "marketing and operations leaders") without saying what a script is for, what platform it targets, or what output is produced. Against ~30 near-identical siblings (zh-scriptlist-kit, zh-talk-kit, zh-story-kit, xhs-script-kit, dy-script-kit), nothing here lets an agent separate this tool from the pack.

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 guidance, no exclusions, and no named alternative. "Get a structured, repeatable workflow you can run today" is marketing copy, not a routing condition, so an agent has no basis for choosing this over the many sibling kits.

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