comment_generate_system

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, but it only says 'generate' without explaining side effects, what files are created, whether existing code is overwritten, or what the output of generation looks like. It also gives no hint why the optional api_key might be needed.

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 a single short sentence with the key verb front-loaded, which is structurally simple. But the brevity reflects under-specification rather than deliberate conciseness; the redundant 'comment/discussion' phrasing does not save space while adding little clarity.

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 scaffolding tool with no output schema and no annotations, the description is incomplete: it fails to specify output locations, generated artifacts, language/framework assumptions, or behavior around existing files. The minimal purpose statement is a starting point but leaves too many operational details unknown.

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?

The input schema documents 'directory' as 'Project directory', but api_key has no schema description and the description adds no meaning for either parameter. With schema_description_coverage at 50%, the description was expected to compensate for the undocumented api_key and it does not.

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 states a specific action ('Generate') and a resource ('comment/discussion system'), so an agent can infer a scaffolding/generation task. However, 'comment/discussion' is loose and the description does not distinguish this from sibling tools such as comment_add_moderation or comment_add_threading, nor from the many other *_generate_system tools.

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 about when to use this tool versus alternatives like comment_add_threading or comment_add_moderation, and no prerequisites are mentioned. The only context is the tool name and the sibling list, which is not enough for an agent to select it confidently.

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