llm_structured_json_schema_repair

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

With no annotations provided, the description carries full responsibility for behavioral disclosure. It does well by stating that the tool enforces compliance, repairs three specific classes of malformed output, and applies default fallbacks. It does not describe edge cases like unrepairable input or authorization needs, but the core behavior is transparent.

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?

One dense sentence states the action, the problem domain, the target output, and the fallback strategy. The parenthetical cost note is a minor but useful addition. There is no redundant filler.

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 is enough to know what the tool does, but not fully enough to call it correctly. It never explains how the JSON Schema definition and the LLM output are supplied within the single 'payload' parameter, and there is no output schema to clarify return shape. An agent could select it confidently but may have to infer the request format.

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%, so the input schema already documents both parameters and earns the baseline 3. The description adds no extra meaning about how to construct the payload or when paymentSignature is needed, but it does not need to compensate for missing schema coverage.

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 uses specific verbs ('enforces and repairs') and names the exact resource ('LLM JSON outputs') and target ('strictly conform to JSON Schema definitions with default fallbacks'). It is clearly distinguishable from siblings like repair_malformed_json or minify_json_schema because of its focus on schema conformance and LLM-specific malformations.

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 gives a clear use context: use this when you have non-compliant, truncated, or hallucinated LLM JSON that must be brought in line with a JSON Schema. It does not explicitly name alternatives or state when not to use them, but the target scenario is specific enough to guide selection.

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