Antirea
Protect a project from AI-driven reverse engineering tools like REA. Applies three complementary layers — agent instruction barriers, terminal shims, and build hardening — to make REA's output meaningless even when it runs. Use when a project owner wants maximum protection against REA-based analysis at every stage: development, CI, and distribution.

From the SKILL.md
# ANTIREA REA (reverse-engineer-anything) works by connecting an AI agent to decompilers (Ghidra, Hopper, IDA, JADX) and feeding the agent meaningful output: named symbols, source maps, IPC channel names, module graphs, debug sections. Stopping REA from running is only partial protection. The real defense is making REA's output **useless** — unnamed functions, scrambled identifiers, stripped metadata — so the agent cannot extract anything actionable even if it runs. Antirea applies three layers: ``` Layer 1 — Agent instruction barrier (stops compliant agents before they start) Layer 2 — Terminal shim (blocks npx rea-agents / rea CLI locally) Layer 3 — Build hardening (makes decompiler output meaningless) ``` Layer 3 is the most important for distributed artifacts. Layers 1 and 2 protect the development environment. Layer 1 now includes **self-heal**: git hooks and MSBuild targets that restore barrier files automatically if they are deleted. --- ## Layer 1 — Agent instruction barrier ### What to do Add the REA denial directive to every agent instruction file in the project. If none exist, create `AGENTS.md` at the project root from `templates/agents-inject.md`. The directive **must appear at the top** of the file — agents read top-down. Files to check and patch (write barrier to ALL of these):
