diff_env_requirements

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

The description explains the output format (buckets and counts) which is sufficient for a read-only diff operation. However, it does not disclose whether the inputs are file paths or content, nor does it mention any side effects or error conditions. With no annotations, this is a moderate level of transparency.

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 sentences with no extraneous information. It is direct and front-loaded with the core action, making it highly efficient for an agent.

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 diff tool with two string inputs and no output schema, the description covers the essential behavior and output format. Minor missing details like order sensitivity or input type are outweighed by the tool's low complexity.

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 defines two string parameters ('left', 'right') without descriptions, and the tool description adds only that they are 'pip-style requirement files'. This leaves ambiguity about whether they are file paths or file contents, which is critical for correct usage. The low schema coverage (0%) makes the description insufficient.

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 verb 'diff' and the resource 'two pip-style requirement files', distinguishing it from sibling 'collection_diff' which applies to collections. The output buckets are also mentioned, making the purpose unambiguous.

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?

No information is provided about when to use this tool compared to alternatives like 'collection_diff' or other analysis tools. There is no guidance on prerequisites or context, leaving the agent to infer usage.

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