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

No annotations are provided, so the description carries the full burden. It offers one genuine behavioral hint — that the deliverable is a 'copy-paste prompt pack with examples' rather than finished titles — but says nothing about output shape, whether any external WeChat access is needed, or what happens when the optional query is omitted.

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 promotional filler ('production-ready', 'you can run today') that consume the entire budget without front-loading the tool's actual function. The space is spent selling rather than informing.

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, no output schema, and no parameter explanation, the description is the only source of context — and it omits what the tool returns, what a prompt pack contains, and how it differs from the dozens of neighboring title and copy tools. An agent cannot confidently decide to call it.

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, so the schema already explains 'query'. The description adds no meaning about how the query scopes the workflow or what an unscoped call returns, leaving it at the baseline for fully-covered schemas.

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 tool name ("wechat title system") and wraps it in marketing language ("production-ready", "for marketing and operations leaders") without saying what the tool actually does or produces. It never states a concrete verb such as 'generate' or 'write' applied to titles, and gives no basis for distinguishing it from siblings like xhs-title, title-writer-pro, or viral-title-writer.

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 exclusion criteria, and no mention of any alternative tool. The only audience hint ('marketing and operations leaders') does not tell an agent which situations should route here versus the many other title/copywriting tools in the sibling list.

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