validate_generated_mesh

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

No annotations provided. The description mentions validation checks but does not disclose if the tool modifies the file, whether it is read-only, or what the response format is. Without annotations, the description should provide more behavioral context.

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 concise with a clear opening sentence, a bulleted list of checks, and an Args section. The Args section slightly duplicates the schema but overall is well-structured and not verbose.

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?

No output schema is provided, and the description does not explain what the validation returns (e.g., pass/fail, detailed errors). It also omits prerequisites like file existence. For a single-parameter tool, more detail on outcomes is expected.

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 description explains that file_path is a path to an STL, OBJ, or GLB file, adding value beyond the schema's simple string type. With 0% schema description coverage, the description effectively compensates for the missing parameter documentation.

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 tool validates a 3D mesh for printing readiness, listing specific checks (file format, dimensions, polygon count, manifold). This is a specific verb+resource combination, but it does not explicitly distinguish from sibling tools like 'validate_and_prepare_mesh' or 'analyze_mesh_geometry'.

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?

No guidance on when to use this tool versus alternatives (e.g., 'repair_mesh', 'validate_and_prepare_mesh'). The description lacks context about prerequisites or exclusions.

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