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

With no annotations provided, the description carries the full burden of behavioral disclosure. It helpfully mentions specific limits ('tagline max 100 chars, features max 30 items, tags max 30') which are valuable behavioral constraints not evident from the schema. However, it doesn't describe file creation behavior (overwrite vs. create new), error handling, or output format details beyond mentioning it creates a 'formatted file.'

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?

The description is extremely efficient - two sentences that convey purpose, outcome, and key constraints. Every word earns its place, with the first sentence stating what the tool does and the second providing critical behavioral limits. No wasted words or redundant information.

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?

Given the complexity (10 parameters, file generation tool) and the presence of an output schema (which means return values are documented elsewhere), the description provides adequate but incomplete context. It covers the core purpose and key constraints but leaves many parameter meanings unexplained. For a tool with 10 parameters and no annotations, more guidance on parameter usage would be beneficial.

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?

With 0% schema description coverage for 10 parameters, the description provides minimal parameter information. It only mentions three parameters indirectly through limits (tagline, features, tags) but doesn't explain what 'project_dir', 'package_name', 'category', 'tools_summary' or other parameters mean or how they should be formatted. The description doesn't adequately compensate for the complete lack of schema descriptions.

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 clearly states the specific action ('Generate a LAUNCHGUIDE.md'), the resource ('for MCP Marketplace submission'), and the outcome ('Creates a formatted file ready to submit'). It distinguishes this tool from siblings like 'scaffold_server' or 'build_package' by focusing specifically on documentation generation for marketplace submission.

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 description provides clear context about when to use this tool ('for MCP Marketplace submission'), but doesn't explicitly state when NOT to use it or mention specific alternatives among the sibling tools. The context is sufficient to understand this is for preparing marketplace documentation, but lacks explicit comparison to other documentation or packaging tools.

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