x64dbg/x32dbg Reverse Engineering

x64dbg/x32dbg Reverse Engineering is a skill for Claude Code from SetsunaYukiOvO/x64dbg-mcp. It costs 66 tokens per session (2,165 once invoked), scanned A, original, MIT.

A guide for using x64dbg and x32dbg, Windows debuggers for examining running programs and their machine-code instructions. It covers binary analysis, reverse engineering, unpacking, and vulnerability research.

In plain words
What is it for?
Use it to debug Windows executables, trace API calls, analyze algorithms or protocols, unpack protected programs, patch binaries, or investigate vulnerabilities.
Why use it?
It gives the coding agent a structured way to inspect program execution, memory, registers, modules, and system behavior.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

x64dbg/x32dbg Reverse Engineering scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
