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

No annotations provided, so description bears full burden. It mentions deterministic CadQuery and no network call, which are helpful. However, it does not disclose error handling, performance characteristics, or any side effects. More detail would improve transparency for a complex tool.

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, information-dense sentence that efficiently captures the tool's purpose, input constraints, and key features. It is front-loaded and free of fluff, though splitting into two sentences could improve readability.

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 tool's complexity (7 params, many shape options) and no output schema, the description covers input format, shape types, deterministic behavior, and no network use. It lacks explicit output description (e.g., format or file type) and has no annotations. Fairly complete but could add more context.

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 57% schema description coverage, the description adds value by summarizing shape types and mentioning tapered (hinting bottomShape is optional). It clarifies input format (JSON only). But many detailed constraints are left to the schema; description does not fully compensate for gaps.

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 generates a solid plug to fill holes/cavities, lists all supported shapes (circular, rectangular, stadium, polygon, freeform), and mentions uniform or tapered options. This distinguishes it from sibling tools like caps or meshes.

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 does not explicitly state when to use this tool versus alternatives. However, sibling tool names (caps, meshes, repairs) are distinct, and the description implies JSON-only input. No explicit when-not or alternative recommendations, but the shape-specific schema descriptions provide guidance within the tool.

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