Vibe-Reverse-Engineering AGENTS.md

Instructions for analysing Windows executable files and game behaviour using both code inspection and runtime tracing. The toolkit records discoveries in knowledge-base files that guide later analysis.

In plain words
What is it for?
Use them to inspect .exe and .dll files, observe programs while they run, trace Direct3D 9 frames, query stored discoveries, and investigate game behaviour.
Why use it?
They tell an agent which analysis method and tool to use for different questions and how to preserve findings across investigations.

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

Vibe-Reverse-Engineering AGENTS.md 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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 124 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Vibe Reverse Engineering — Agent Instructions

LLM-friendly static and dynamic analysis toolkit for x86/x64 PE binaries (.exe / .dll), combining static analysis (retools), dynamic analysis (livetools via Frida), and D3D9 frame tracing. Work is organized around per-game knowledge base files (kb.h) that accumulate discoveries and feed back into richer decompilation.

This file is the canonical, harness-agnostic instruction set. Claude Code loads it via .claude/CLAUDE.md; Cursor, Copilot, Codex, and other agents read it directly. Deeper references live under .claude/ and apply to every harness:

  • Tool catalog (every retools / livetools / dx9tracer command, syntax, caveats): .claude/references/tool-catalog.md
  • Tool dispatch (which tool for which question; what runs inline vs delegated): .claude/rules/tool-dispatch.md
  • Analysis workflow (bootstrap ordering, Ghidra backend, index/query, parallel patterns): .claude/rules/subagent-workflow.md
  • Skills (dx9-ffp-port, dynamic-analysis): .claude/skills/ — canonical copies. Non-Claude harnesses self-install them (see "Skill Setup" below).
  • Custom agents (static-analyzer): .claude/agents/ — canonical definitions. .cursor/agents/, .github/agents/, and .kiro/agents/ hold thin harness-native mirrors that defer to the canonical files, so only the .claude/agents/ copies get edited.

Skill Setup (do this first on non-Claude harnesses)

Claude Code reads .claude/skills/ natively — skip this section. Every other harness: check whether the dx9-ffp-port and dynamic-analysis skills are available to you. If not, install them into your own skills directory before starting work:

npx skills add ./.claude/skills -a <your-agent> -y   # e.g. -a cursor, -a copilot, -a kiro-cli

Omit -a to let the CLI auto-detect your harness. The source path must be ./.claude/skills — a bare . finds nothing (the CLI skips the current project's agent directories).

If npx is unavailable or your harness isn't supported by the CLI, copy manually: each .claude/skills/<name>/ folder goes verbatim into your harness's skills directory (Cursor: .cursor/skills/, Copilot: .github/skills/, Kiro: .kiro/skills/, .agents/skills/ for agents following that convention).

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.

Vibe-Reverse-Engineering AGENTS.md is an instructions file published in the GitHub repository Ekozmaster/Vibe-Reverse-Engineering (46 stars, last pushed 1mo ago), licensed MIT. It adds 2,209 tokens to every session, about $0.0110 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
