diff_diff_text

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

No annotations exist; description provides basic functional behavior and return type but omits edge cases, performance implications, or assumptions about input size. Adequate for a simple tool but lacking depth.

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, front-loading the purpose and return type. No wasted words, easily scannable.

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?

Given 5 parameters (some optional) and multiple sibling tools, the description lacks completeness. It does not explain optional parameters or contrast with siblings. The output schema is described, but overall it is under-specified.

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 does not mention any parameters. The agent must infer meaning from parameter names and types alone, which is insufficient for optional parameters like context and labels.

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 (compare two text strings) and resource, and details the return structure. It distinguishes from file- and word-based diff tools by specifying text strings and unified diff output.

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 does not provide any guidance on when to use this tool versus alternatives like diff_diff_words or diff_diff_stats. No context on prerequisites or preferred scenarios.

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