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

Annotations already declare readOnly, idempotent, non-destructive, non-open-world, so the safety profile is covered without the description. The description adds only the meta-detail that describe_operation supplies the native request schema; it says nothing about pagination, response shape, or what 'changes' are tracked against.

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?

Short, but the same sentence is duplicated verbatim, so a third of the content is pure waste. Nothing is front-loaded about purpose or behavior; the operation ID adds no value to an agent choosing the tool.

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?

With no output schema, a free-form query object, and 0% schema coverage, the agent cannot tell what this endpoint returns or what filters are valid. The single useful element is the redirect to describe_operation, which is insufficient for a parameterized version-scoped read endpoint.

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% across 2 parameters, including a free-form nested 'query' object with additionalProperties, so the description must compensate and does not. The path template only echoes the required versionId that the schema already marks required, and the free-form query filters remain entirely unexplained.

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 name/title ('GET /api/negotiation/versions/:versionId/changes') twice, with no plain-language statement of what a 'change' is or what the call returns. It does not differentiate this tool from its very close sibling get_negotiation_versions_by_versionId_d_aadb975315bfc2f5d2fe7dc6 or from get_negotiation_versions_by_id_comments.

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?

There is no statement of when to call this versus the other negotiation version sub-resource endpoints. The only actionable guidance is a pointer that describe_operation provides native request schemas, which is schema-discovery advice, not usage guidance.

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