diff_responses

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

No annotations are provided, and the description fails to disclose behavioral traits: whether it modifies state, if it sends actual HTTP requests (which could be destructive), or if responses are persisted. Minimal transparency beyond stating it executes requests.

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?

Two sentences, front-loaded with action, second sentence adds use cases. No redundant information; every sentence earns its place.

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?

Despite complex nested parameters (two request objects with multiple subfields) and no output schema, the description omits crucial details: what the comparison output looks like, ordering of requests, and any limitations. Incomplete for a comparison tool handling possibly destructive operations.

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 100% with detailed property descriptions (labels, methods, auth types). The description adds no extra meaning beyond the schema, so baseline score of 3 applies.

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 it executes two requests and compares their responses, with specific use cases (detecting regressions, comparing environments). This distinguishes it from sibling tools like 'request' (single request) and 'assert' (assertions), but doesn't detail the comparison output format.

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 usage for regression detection and environment comparison but provides no explicit when-to-use vs. alternatives (e.g., 'request', 'bulk_test', 'assert'). No guidance on when not to use this tool.

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