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 says 'Regenerate' which implies overwriting the existing CATALOG.md, but it does not explicitly state that this is a destructive operation, nor does it mention permission requirements or any other side effects. This is a significant gap.

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 sentence that is front-loaded with the action and purpose. It is concise with zero waste, conveying exactly what the tool does without extraneous detail.

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 tool with no parameters and an output schema, the description is relatively brief. It states the purpose but lacks usage context (when to call) and behavioral details (side effects). Given the simplicity of the tool, it is borderline adequate but could be more complete with guidance on when regeneration is appropriate.

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 tool has no parameters, and the schema coverage is trivially 100%. Per the rubric, 0 params gives a baseline of 4. The description adds no parameter information because none is needed.

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 verb 'Regenerate' and the resource 'CATALOG.md', and specifies the purpose 'for cross-conversation tool discovery'. It is specific and unambiguous, though it does not explicitly differentiate from sibling tools. No sibling appears to have the same function, so this is acceptable.

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 gives no guidance on when to use this tool versus alternatives, such as after adding new tools or when the catalog becomes stale. It does not mention any prerequisites or conditions that should trigger invocation.

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