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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, so the safety profile is covered structurally. The description contributes nothing beyond that — no mention of pagination, response shape, error behavior (e.g., 404 for unknown version), or permission requirements.

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 same endpoint path is printed twice in adjacent sentences, which is pure waste. What remains is an operation ID and a pointer to describe_operation, so there is no front-loaded substance.

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?

This is a simple read-by-id endpoint with no output schema, so the description must at least convey what is returned and how the identifier is obtained. It does neither, and the nested 'query' object remains unexplained, leaving the agent to call describe_operation first.

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% for 2 parameters, so the description carries the burden and does not meet it. The ':id' placeholder weakly implies the path parameter is a version identifier, but the 'query' object parameter and the id's format/limits (minLength 1, maxLength 2000) are undocumented anywhere in prose.

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 only restates the HTTP path twice ('GET /api/negotiation/versions/:id'), which is a tautology of the title and name rather than a plain-language statement of what the tool returns. An agent can infer 'fetch a negotiation version by id' from the path, but the description adds no distinguishing detail versus siblings like get_negotiation_versions_by_versionId_* or get_versions_by_id_*.

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 statement of when to use this tool, when to prefer a sibling, or what prerequisites exist. The only directional hint is the note that describe_operation provides native request schemas, which is a meta-instruction rather than usage guidance for choosing this endpoint.

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