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

No annotations are provided, so the description must carry behavioral context. It describes the reasoning/combination behavior and gives examples, but does not disclose whether this is read-only, what input constraints apply, or what the returned output contains. The presence of an output schema partially mitigates the missing return-value detail.

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 compact and front-loaded with purpose and examples, followed by a brief parameter clarification. No filler or redundant repetition of schema fields.

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 tool with an output schema, the description covers the core purpose and input source. However, it lacks details about the finding object structure and any preconditions or result expectations, making it slightly incomplete for an agent invoking it in unusual contexts.

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 only says 'string' for findings_json, and schema description coverage is 0%. The description adds that it is a JSON array of finding objects from hunt/review/report, but does not specify the shape or required fields of those objects, so parameter semantics remain partially 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 uses a specific verb ('Reason') and identifies a clear resource ('findings for exploit CHAINS') with concrete examples of impact escalation. It clearly distinguishes this tool from sibling finding-generation tools like hunt/review by focusing on chaining existing findings.

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 states that input should come from hunt/review/report, strongly implying the right context for use. It does not explicitly name alternatives or exclusions, but the source hint provides sufficient guidance.

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