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

No annotations are provided, so the description must carry the full behavioral burden, yet it only says the output is a 'prompt pack with examples'. It does not explain whether the tool generates content on demand, returns static assets, requires a query, or has side effects or limits.

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?

It is short, but the opening is a product pitch ('production-ready', 'you can run today') rather than useful front-loaded operational detail. The two sentences are concise in length but low in information density.

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 one-optional-parameter tool with no annotations and no output schema, an agent still needs to know what the tool returns and how it behaves. The description does not clarify whether this is a title generator, prompt library, or analysis tool, leaving a significant gap.

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%, so the optional query parameter is already documented in the schema. The description adds no meaning about how 'query' scopes the analysis or what kind of scope it accepts, so baseline 3 is appropriate.

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 names the XHS title domain and a deliverable ('prompt pack with examples'), but it never states a concrete action such as generating, reviewing, or scoring titles. It largely restates the tool name and adds audience/marketing framing rather than a specific verb+resource.

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 use this tool versus siblings such as xhs-viral-copywriter, title-writer-pro, or viral-title-writer. 'For marketing and operations leaders' identifies an audience, not a usage condition, and no exclusions or prerequisites are given.

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