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

With no annotations, the description carries the full burden. It discloses the cost ($0.05 USDC) but does not state whether the operation is read-only, if there are side effects, or what the output format is. For an audit tool, it likely doesn't mutate data, but this is not stated.

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 description is two short sentences: the first states the purpose, the second states the cost. No redundant information, no filler. It is front-loaded and efficient.

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 moderate complexity (arrays, matching logic, no output schema), but the description only covers purpose and cost. It omits what the tool returns, how results are presented, error conditions, and any usage examples. This is a substantial gap for an auditor tool.

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%, so the description must compensate. It implies that 'contracts' contain expected status, content-type, field, type, and stable-value rules, and that 'responses' are recorded API responses. However, it doesn't explain the id linking scheme, required fields, or additionalProperties, leaving gaps.

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 clearly states the tool's function with a specific verb 'Compare' and resource 'recorded API responses' against 'explicit status, content-type, field, type, and stable-value contracts'. It names the key contract dimensions, which differentiates it from sibling audit tools, though it doesn't explicitly name alternatives.

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 guidance on when to use this tool versus alternatives. It notes a cost but no prerequisites, constraints, or exclusions. The description does not mention any specific use case or conditions under which this tool is preferred over sibling auditors.

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