C2.1/5.0
Behavior2/5

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

The annotations already declare destructiveHint=true and idempotentHint=true, so the destructive and idempotent behavior is known. However, the description adds nothing beyond the endpoint—no mention of side effects, irreversible deletion consequences, cascade effects, or any behavioral details that would help an agent understand what happens on delete. With annotations present, the bar is lower, but the description still contributes essentially zero behavioral context beyond what annotations already convey.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is short and front-loaded with the action, which is good for conciseness. The endpoint line and the Args line are structured clearly. However, brevity here is under-specification rather than efficient compression—each line is technically useful but the total content is thin, and the description is essentially a restatement of the tool name plus a schema echo.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool is simple (one required param) and has an output schema, so the bar for completeness is modest. But the description does not explain what a RemotePathMapping is, when deletion is appropriate, whether deletion is reversible, or anything about expected results. An agent would need to infer most context from the name and endpoint alone. The output schema presence reduces the return-format burden, but the semantic gaps remain significant.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must compensate. It states 'id: Path parameter,' which adds one small fact (that id is a path parameter rather than a body/query parameter) beyond the schema's integer type and title. This is minimal and does not explain what the id refers to, what values are valid, or any constraints. For a tool with a single required parameter, the compensation is weak.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose2/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description 'Delete RemotePathMapping' is essentially a tautology of the tool name 'delete_remotepathmapping_by_id'. The endpoint URL adds marginal context (the API path and that it uses an {id} path segment), but the description does not differentiate this tool from its many delete siblings (delete_movie_by_id, delete_tag_by_id, etc.) beyond the resource name. The verb and resource are stated, but nothing distinguishes it.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives. The sibling list includes update_remotepathmapping_by_id, create_remotepathmapping, and get_remotepathmapping_by_id, but the description never mentions them or any selection criteria. There are no when-to-use, when-not-to-use, or prerequisite instructions.

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