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

With no annotations, the description carries the full behavioral burden. The phrase 'delivered as a copy-paste prompt pack with examples' is the one genuinely useful disclosure about output form, but it says nothing about how the optional query changes the result, whether output is static boilerplate, or anything about length or safety.

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 structural bloat, but they are front-loaded with promotional framing ('production-ready', 'you can run today') rather than the concrete fact of what the tool returns. Length is fine, information density is low.

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 tool whose entire value is a templated prompt pack, the description never says what content the pack covers (live-stream scripts, run-of-show, talk tracks?) or for which platform. Given the huge sibling family of identical *-kit tools, that omission leaves the agent unable to disambiguate.

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 ('Optional user query to scope the analysis'), so the schema already carries the meaning and the baseline is 3. The description adds nothing about how the query scopes the generated pack.

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's 'live kit' concept in marketing language ('a production-ready live kit system') without ever stating concretely what the tool produces or which platform it serves. In a sibling set containing dy-live-kit, sph-live-kit, gzh-live-kit, xhs-live-kit and zh-live-kit, nothing here identifies this as the Zhihu variant, so an agent cannot pick it over its near-identical siblings.

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?

The only scoping is an audience label ('for marketing and operations leaders'), which is not a when-to-use condition. There is no explicit trigger, no exclusion, and no reference to any alternative tool such as dy-live-kit or live-script.

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