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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds nothing beyond that — no indication of what the version list contains, ordering, pagination, or permission requirements — so it fails to exploit the lower bar.

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?

It is short, but the first sentence is duplicated verbatim, so half the content is waste. The remaining sentence is a generic pointer to describe_operation rather than tool-specific information.

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?

The tool has a nested params object, no output schema, and zero parameter documentation, yet the description explains nothing about inputs or expected results. Pointing at describe_operation is a partial mitigation for schema lookup but leaves an agent unable to call this tool confidently from the definition alone.

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 merely echoes the path placeholders ':entity' and ':id' without explaining what entity types are valid or which identifier 'id' refers to. With two nested, undocumented parameters, the description needed to compensate and does not.

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 is just the raw endpoint path repeated twice ('GET /api/negotiation/:entity/:id/versions'), which restates the title rather than explaining what the tool returns or what a 'version' of a negotiation is. It gives no basis for distinguishing it from the many sibling endpoints such as get_negotiation_versions_by_id or get_negotiation_by_entity_by_id_current.

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 use this endpoint rather than the current/draft/redline negotiation siblings or get_negotiation_versions_by_id. The only forward-looking hint is a pointer to describe_operation for request schemas, which is schema discovery, not usage guidance.

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