generate_json2_payload

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

Annotations already indicate readOnlyHint, idempotentHint, and non-destructive. The description adds 'without network access', clarifying local execution. It does not contradict annotations. Additional context like auth needs or rate limits is not needed given the annotations.

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 a single concise sentence that effectively communicates the tool's purpose and key behavioral trait (no network access). It is well front-loaded with no unnecessary words.

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?

Despite having an output schema, the description lacks context about what JSON-2 is, what fields the preview includes, and how to correctly fill the 7 input parameters. The agent may struggle to invoke the tool correctly without additional guidance.

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%, so the description must compensate. It provides no information about parameter meanings, leaving the agent to infer from names alone. Generic parameters like 'args' and 'kwargs' are particularly ambiguous.

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 'Build', the resource 'JSON-2 request preview', and the constraint 'without network access'. It distinguishes the tool from siblings, none of which mention JSON-2 or payload preview.

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 the tool is used to generate a preview of a request payload, but it does not explicitly state when to use it vs alternatives or provide guidance on prerequisites or conflicts. Usage context is implied by the tool name and description.

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