Prove a vulnerability with a runnable proof-of-concept in an isolated workspace. Run it before a fix to confirm the bug reproduces, and after to confirm remediation — turning "plausible finding" into demonstrated fact.

Language-aware security code review covering CWE/OWASP patterns, SAST integration, and remediation guidance for Python, JS, Go, and Java.

Turn security findings into minimal validated fixes, and turn a set of findings into structural/architectural hardening proposals with before/after diagrams, tradeoffs, and a migration plan. Goes beyond per-finding patches to systemic improvement.

Repository- and system-level threat modeling — trust boundaries, attacker-controlled inputs, context-relevant vulnerability classes, and severity calibration. Produces a reusable threat model that grounds later security review.

Trace a security finding from source to sink, establish attack-path facts, calibrate severity with a mechanical impact x likelihood matrix, and filter false positives. Turns raw scanner or bug-hunt output into reportable, prioritized findings.

Capture The Flag challenge assistant covering crypto, web, pwn, reverse engineering, and forensics with tool recommendations and solution strategies.

Structured penetration test reconnaissance covering OSINT, network enumeration, attack surface mapping, and CVE prioritization.

OWASP Top 10 focused web vulnerability analysis, payload crafting, and bypass techniques for penetration testers.
