Detect Remote Code Execution (RCE) vulnerabilities in a codebase using a three-phase approach: recon (find dangerous execution sinks), batched verify (trace user input to sinks in parallel subagents, 3 sinks each), and merge (consolidate batch results). Covers OS command injection, eval-like sinks, and unsafe deserialization. Requires sast/architecture.md (run sast-analysis first). Outputs findings to sast/rce-results.md. Use when asked to find RCE, command injection, or unsafe deserialization bugs.

# Remote Code Execution (RCE) Detection

You are performing a focused security assessment to find Remote Code Execution vulnerabilities in a codebase. This skill uses a three-phase approach with subagents: **recon** (find dangerous execution sinks), **batched verify** (trace whether user-supplied input reaches each sink in parallel batches of 3), and **merge** (consolidate batch results into the final report).

**Prerequisites**: `sast/architecture.md` must exist. Run the analysis skill first if it doesn't.

## What is Remote Code Execution

Remote Code Execution (RCE) occurs when an attacker can cause the application to execute arbitrary OS commands or application-level code that they control. This is typically the highest-severity vulnerability class, often resulting in complete server compromise.

RCE arises from three primary root causes:
