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 does disclose the pack's contents (complete prompt, usage guide, edge-case handling), which is useful, but says nothing about whether the call has side effects, what the response shape is, or whether the prompt pack is static versus generated per 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?

Three short sentences, but the opening ("Turn expertise into output") and the closing claim ("professional results in minutes") are marketing filler that consumes the front-loaded position without informing an agent. The middle sentence about contents is the only load-bearing one.

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 simple retrieval-style tool this could be adequate, but the definition omits the two things an agent most needs: the platform scope (Douyin) and what the returned prompt pack looks like. With 500+ siblings and no output schema, those omissions are material rather than cosmetic.

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?

Only one optional parameter exists and the schema documents it at 100% coverage ("Optional user query to scope the analysis"). The description adds no meaning about how the query influences the returned prompt pack, so the baseline 3 applies rather than a penalty or bonus.

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 with marketing framing ("Turn expertise into output", "unbox kit prompt pack") instead of stating a concrete verb and resource. It does narrow the audience to "restaurant and brand teams", but an agent cannot tell what artifact it actually gets or how this differs from the many platform-specific unbox siblings (xhs-unbox-kit, gzh-unbox-kit, sph-unbox-kit, zh-unbox-kit).

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 explicit when-to-use statement, no exclusions, and no routing to alternatives. In a namespace containing four near-identical unbox kits, the description never says this one is the Douyin variant or when to prefer it over the others, leaving the choice to inference from the "dy-" prefix alone.

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