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

Annotations already declare readOnlyHint=true and idempotentHint=true, so the description is not required to state safety. It does add value by detailing what the change set contains (field, before/after values, status), which goes beyond the structured hints. However, it does not disclose potential pagination or the response structure, leaving some behavioral ambiguity. No contradiction with annotations.

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?

A single sentence that concisely states the tool's output without extraneous words. The key information is front-loaded: what is returned and its composition. No redundancy.

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?

For a simple read-only tool with one well-documented parameter and annotations covering safety, the description is mostly adequate. However, there is no output schema, and the description does not clarify whether the result is a list of changes, how pagination works (if any), or the exact structure of the response. The phrase 'per page' is ambiguous, leaving room for misinterpretation.

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?

The schema covers the only parameter (order_id) with a clear description ('The fix order id, as returned by list_tasks'). With 100% schema coverage, the description adds no further parameter detail, so a baseline of 3 applies per the rubric.

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 states a specific verb ('Return'), a clear resource ('change set of a fix order'), and elaborates on the content (per page: field, value before and after, status). This clearly distinguishes it from sibling tools like get_fix_catalog or get_fix_plan, which return different aspects of fix orders.

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?

The description implies its purpose (retrieving a fix order's changes) but provides no explicit guidance on when to use it versus alternatives such as get_fix_plan or get_fix_catalog. It neither states prerequisites nor mentions exclusion criteria, leaving the agent to infer from the tool name and sibling context.

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