winops_json_read

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds the return format (including a success flag) and an example call, which gives behavioral insight beyond the annotations. It doesn't describe error behaviors (e.g., file not found), but the return format implies error handling via the success flag.

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 extremely concise: one sentence for purpose, a return format block, and a short example. Every sentence earns its place. No fluff.

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 single-parameter read tool, the description is complete. It specifies the purpose, return format, and provides an example. Since there's no output schema defined, the description appropriately documents the return shape. It lacks error-handling details, but that might be covered by the success flag. Overall, sufficient for the tool's simplicity.

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 already describes the parameter 'path' as 'Path to the JSON file.' The description provides an example with the path syntax, which adds a concrete usage pattern. This is a slight enhancement over the schema, so above baseline 3.

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 'Read and parse a JSON file,' which is a specific verb+resource. The sibling tools (json_write, json_validate, json_patch, etc.) make the unique purpose obvious, and the tool name itself is 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?

The description does not explicitly mention alternatives or exclusions, but the verb 'read' and the context of sibling tools make the intended use clear. It provides a usage example and return format, which gives practical guidance. Missing explicit 'when not to use' but adequate for such a simple tool.

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