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

No annotations are supplied, so the description carries the full burden, and it mostly delivers marketing rather than behavior. The one useful hint is that it 'ships as a full prompt kit with step-by-step instructions', implying the call returns a reusable workflow artifact, but there is no disclosure of what is actually produced, whether state changes, or how long the output is.

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 space is spent on 'no prompt engineering needed' and a '30-day support promise' instead of the tool's behavior. The most informative content, that it is a prompt kit with step-by-step instructions, is buried behind the vague 'intelligence pack' framing.

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 callable tool with one input parameter, no annotations, and no output schema, an agent still cannot tell what invoking this returns or when it beats the dozens of similar gzh-* siblings. The description is a sales blurb rather than an operational definition.

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, 'query', and the input schema fully documents it at 100% coverage, so the schema does the heavy lifting. The description adds nothing about how the query scopes the generated workflow, so this sits at the baseline rather than above it.

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 opens with 'AI-powered restaurant & brand intelligence pack', which is confusingly unrelated to a WeChat (gzh) viral-article writer, and the actual action is only described circularly as 'generate a ready-to-use gzh baokuan writer workflow'. It restates the tool name in marketing terms rather than stating a concrete verb + resource outcome, and it does nothing to separate itself from the many gzh-* kit 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?

There is no guidance on when to call this tool, when not to, or which sibling (e.g. baokuan-copywriter, gzh-adcopy-kit, gzh-topic-kit) it should replace. The only usage-adjacent statement, 'no prompt engineering needed', is promotional rather than a routing condition.

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