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

The description discloses key behavioral traits: it returns repair suggestions as corrected values with associated rules, provides PASS/FAIL/REVIEW verdicts with reasons and proof, and performs validation plus repair suggestion in a single call. It complements the annotations by clarifying that it only suggests repairs, not actually applies them. No contradiction with annotations found.

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 filler. The first sentence states the core functionality and the repair-suggestion behavior, and the second clarifies output verdicts. It is efficiently front-loaded and 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?

The description covers the core behavior, output verdicts, and the combined validation+repair nature of the tool. Given the absence of an output schema, it does a good job explaining return values. It could benefit from explicit guidance on choosing this tool over the separate validate/repair siblings, but it is otherwise complete.

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 coverage is 100%, with all three parameters described in detail (e.g., api_key format, blueprint default, structured_data keys open). The description adds no additional parameter-specific semantics beyond what the schema already provides, so the baseline score of 3 is appropriate.

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 validates structured data against a Blueprint and, on failure, provides repair suggestions (corrected values with rules) in the same call. It explicitly references 'validate' for comparison, distinguishing this combined validation+repair functionality from the basic validate tool.

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 when the user wants both validation and repair suggestions in one call, and mentions 'Same verdicts as validate' to align with validation expectations. However, it does not explicitly state when to prefer this over the separate 'validate' or 'repair' sibling tools, so guidance is clear but not fully explicit.

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