This specialized skill acts as an expert debugger, designed for deep root cause analysis of software errors, test failures, and unexpected behavior. It guides the user through systematic debugging processes, including capturing stack traces, isolating failure points, implementing minimal fixes, and providing comprehensive reports detailing the root cause, evidence, specific code patches, and prevention recommendations. Ideal for complex bug resolution and quality assurance.

This structured skill guides users through root-cause-first debugging when an implementer is blocked, verification fails, or repeated attempts at fixing do not converge. It mandates a systematic approach combining local evidence inspection, runtime analysis, and external documentation research to accurately classify the failure's true source (e.g., missing dependency, spec conflict). It prevents speculative patching and generates a clear, actionable fix plan.

This internal helper provides a language-neutral mechanism for investigating stack traces when the source language is unknown. It generates critical checks (e.g., contract checks, boundary checks), minimal reproduction steps, and potential patch targets based solely on the provided trace data, ensuring robust and comprehensive failure analysis regardless of the underlying language.

This internal utility probes JavaScript or TypeScript stack traces to provide deep diagnostic insights. It identifies potential language-specific checks (e.g., async boundaries, type contracts), generates minimal reproduction commands for environments like Node.js, npm, or Jest, and highlights targeted patch areas for efficient debugging and bug fixing.

A comprehensive, structured guide for reverse engineering and analyzing managed .NET/C# binaries. This skill covers the full workflow, including initial identification (CLR check), deobfuscation (using tools like de4dot), static analysis via IL view (dnSpyEx), and dynamic debugging. It is essential for analyzing malware, red team tools, and patching compiled C# applications.

Analyze binaries with radare2/r2 from the command line, including reverse engineering, disassembly, function analysis, imports/strings inspection, patching, binary diffing, hex inspection, and r2 scripting. Supports PE/ELF/Mach-O/DEX/WASM files and sub-tools like rabin2, rasm2, radiff2, and r2pipe.

Delegates coding and analysis tasks from Claude Code to OpenAI Codex CLI or Google Antigravity CLI, maintains topic-aware sessions, and critiques returned results.

This skill covers .NET/C# binary reverse engineering, including managed PE analysis, debugging with dnSpyEx, deobfuscation using de4dot for tools like ConfuserEx, and IL patching. It supports analyzing red-team Sharp* tooling and distinguishing between managed and native binaries.

This skill focuses on reversing JavaScript-based custom DSL and Virtual Machine interpreters, commonly found in risk-control and captcha engines. It involves identifying IIFE and switch-based opcode dispatch patterns, extracting opcode tables, and capturing runtime semantics. The workflow includes static analysis for variable mapping and opcode classification, as well as runtime injection techniques to understand exported functions. It excludes standard WASM and typical Webpack bundles.

Locate vulnerability fixes in vendor patches, diff binaries across versions, and build N-day PoCs. This skill complements binary-diff for authorized security research, helping identify patched bugs and create proof-of-concept exploits for unpatched versions.

A command-line interface skill for radare2, enabling binary reconnaissance, disassembly, analysis, function locating, and lightweight patching without a GUI. Supports various formats like exe, dll, elf, and apk. Ideal for scripting automation and quick terminal-based reverse engineering tasks using r2, rabin2, rasm2, and radiff2.
