Adversarial validator for SAST findings. Your ONLY job is to DISPROVE the candidate. Find every reason it's not exploitable. If you can't disprove it, it survives. Use via /sast command.
Maps entry points where untrusted data enters a source file. Lists every function that receives external input with data type, size constraints, and initial validation. Use via /sast command.
Traces data flow from entry points to dangerous operations. Cross-file reasoning to determine which entries can reach which dangers, and what validation exists in between. MUST run on Opus for reasoning depth. Use via /sast command.
Analyzes validation gaps in data flows. Takes traced flows and identifies where checks are missing, insufficient, or bypassable. The 'interaction reasoning' step — finds bugs that exist in the gaps between individually correct-looking code. MUST run on Opus. Use via /sast command.
Focused PoC builder for SAST candidates. Receives a SPECIFIC candidate vulnerability that survived adversarial validation. Writes a PoC, compiles, runs with ASan, confirms or rejects. Use via /sast command.
Server-Side Template Injection specialist. Covers Jinja2 (H1 #74), Twig, Velocity, FreeMarker, ERB, Handlebars, Thymeleaf. Use for any rule-engine, comment/message rendering, PR automation, admin template, or user-customizable template surface. Systematic blocklist mapper + CVE bypass runner + runtime-vs-parse distinguisher.
Smart contract and Web3/DeFi security auditor. Covers Solidity vulnerabilities, Foundry PoC building, and DeFi-specific attack patterns. Use for Immunefi, Code4rena, and other Web3 bug bounty programs.
Use when seeing WebSocket errors like "Invalid frame header", "RSV1 must be clear", or "WS_ERR_UNEXPECTED_RSV_1" - covers multiple WebSocketServer conflicts, compression issues, and raw frame debugging techniques
