protogen__describe

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

No annotations provided, so description carries full burden. 'Return' implies a safe, read-only operation with no side effects. It does not disclose any potential costs or rate limits, but nothing contradictory.

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?

Single sentence with a prefix tag. It is front-loaded and concise, though the tag adds minor clutter. One sentence is sufficient for the simple purpose.

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?

Minimal but acceptable for a describe tool with no parameters and no output schema. Could benefit from mentioning what 'capabilities' or 'status' entails, e.g., if it returns human-readable text or structured data.

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?

No parameters exist (schema coverage 100%, 0 params). Baseline of 4 for zero-parameter tools applies; no additional parameter description 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?

Description clearly states the tool returns 'ProtoGen capabilities and current CAD environment status'. Verb 'Return' with specific resource distinguishes it from sibling tools like protogen__create_cad_workspace or protogen__health.

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 explicit guidance on when to use this tool vs alternatives. The purpose is clear (introspection), but it does not mention when not to use it or suggest alternatives like protogen__health for health checks.

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