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

Annotations already disclose that the tool is not read-only, not idempotent, and not destructive. The description adds that it validates coverage with an actual drape, which is useful behavioral context beyond the annotations. It still does not explain side effects, persistence, cost, or what a 'seed' is, leaving meaningful gaps for a non-read-only operation.

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?

Two short sentences with no wasted words. The core action is front-loaded, and the secondary validation note is appropriately subordinate.

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?

An output schema exists, so return values need not be explained. However, with four parameters at 0% schema description coverage and no usage guidance, the description is too sparse for an agent to reliably invoke the tool. Annotations help with the safety profile, but key operational details are missing.

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?

Schema description coverage is 0%, and the description provides no explanation of workspace_id, mesh_id, angle, or lock_angle. With four undocumented parameters, the description fails to compensate for the complete lack of parameter semantics in the schema.

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?

States a specific verb and resource: suggesting a starting point (seed) on a mesh. It adds a validation step with an actual drape, giving clear domain purpose. However, it does not explicitly differentiate itself from sibling tools like run_drape or compare_drapes.

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 call this tool versus alternatives such as run_drape or compare_drapes. The phrase 'Validate its coverage with an actual drape' hints at a workflow but does not state prerequisites, sequencing, or when-not-to-use conditions.

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