## GitHub Issue: Agent Lacks 'sweep_payloads' Primitive for Systematic Parameter Fuzzing
The current scan agent architecture operates on a one-shot-per-endpoint basis, delegating all systematic parameter variation to the internal logic of wrapped tools like sqlmap or nuclei. This creates a critical gap: the agent itself lacks a native primitive to command a targeted endpoint with dozens of payload variants and intelligently analyze which specific inputs trigger a successful hit. This limitation hinders autonomous reasoning and restricts the agent's ability to probe novel or unsupported attack surfaces effectively.

The proposed solution is a new agent-level tool called `sweep_payloads`. This primitive would accept parameters for an endpoint, a vulnerability class, HTTP method, and headers, then generate a curated set of N payload variants for systematic testing. Its core function is to move brute-force parameter exploration into the agent's own action space, providing direct, interpretable feedback on which variant succeeded. This is particularly vital for assessing custom APIs, GraphQL endpoints, gRPC methods, or other protocols not covered by mature, off-the-shelf fuzzing tools.

Implementing this primitive addresses a fundamental constraint in automated security scanning. It enables the agent to reason more granularly about exploit success, aligning with the principle of brute-forcing the action space at the appropriate architectural layer. The absence of such a capability currently forces a reliance on black-box tool output, obscuring the causal link between a specific payload and a vulnerability, thereby limiting the agent's adaptability and precision in complex testing environments.
