fuzz_endpoint

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

No annotations are provided, so the description must carry the full burden. It explains the process (replay flow, substitute parameter, use payload categories) but does not disclose potential side effects, permission requirements, rate limits, or whether the original flow is modified. The presence of an output schema (not shown) partly compensates, but the description lacks depth on behavioral traits.

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 succinct, using a single sentence to state the purpose followed by a clear list of arguments. Every sentence adds value, and the structure is front-loaded with the core action.

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 the presence of an output schema (true) and the tool's moderate complexity, the description provides enough context for basic use. It explains the core parameters and payload categories, but misses details like the effect of timeout and whether results are streamed or batched. Overall, it is nearly 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?

With 0% schema description coverage, the description adds significant meaning by explaining each required parameter and providing examples for param_type ('query' or 'json_body') and payload_category ('sqli', 'xss', 'path_traversal'). However, it omits the 'timeout' parameter, leaving its purpose unexplained.

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 action ('Fuzz an endpoint'), the mechanism ('substituting a target parameter with a category of DAST payloads'), and the resource. It is specific and unambiguous, distinguishing the tool from its siblings which do not include fuzzing.

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 for fuzzing endpoints but provides no explicit guidance on when to use or not use this tool, nor does it mention alternatives. The context of sibling tools shows no other fuzzing tool, so the implicit usage is acceptable but lacks precision.

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