VOID Patcher — DIY guide: AI CLI tool RE & safety mechanism removal (R2 offsets, signatures, patches)

VOID Patcher — AI CLI Tool Safety Removal Suite

Python Radare2 Version Tools Mechanisms Status CI License

Reverse engineering and safety mechanism removal for every major AI CLI tool. All offsets verified against specific binary versions. Always re-verify after updates.


What's New in v1.0.0

  • JSON output--json flag for machine-readable patch reports
  • Restore--restore flag to revert any binary to its original backup
  • Multi-user support--user <name> patches into user-specific config paths
  • Cross-platform — Linux (systemd), macOS (launchd), Windows (Scheduled Task)
  • Plugin system — drop custom patch modules into plugins/ for community extensions
  • Notifications — Discord / Telegram / Slack webhooks on patch events
  • SHA256 cache — skip re-patching already-patched binaries by hash
  • Config file~/.void-patcher/config.toml for persistent settings
  • Test suitepytest tests/ with binary mock fixtures
  • CI — GitHub Actions workflow runs tests on every push

RE Methodology

  1. strings + r2 on binary to map safety-related string constants
  2. Find XREF to safety strings → identify check functions
  3. Trace call graph upward to find enforcement points
  4. Patch: jzjnz, call safety_checknop×5, or replace return value
  5. Verify with r2 disassembly diff
  6. Test: run tool with previously-blocked operations

See companion files for per-tool R2 offsets and patch strings.

Claude Code v2 + OpenCode + Gemini CLI — RE Guide & Patches

Node.js Bun Go Radare2 Claude Code OpenCode Gemini CLI


PART 1: Claude Code v2

Binary Structure

Claude Code ships as a Node.js Single Executable Application (SEA). The JS bundle is embedded in the ELF as a blob section.

# Extract the embedded JS bundle
r2 -q -c 'iS~blob' $(which claude)   # find blob section offset
r2 -q -c 'pr <size> @ <offset>' $(which claude) > claude_bundle.js

# Alternative: strings hunt
strings $(which claude) | grep -E '(statsig|permission|requiresPermission|modelGate)' | head -40

Statsig Feature Gates (8 gates mapped)

Claude Code uses Statsig for feature gating. Gates are checked via:

// Pattern in bundle (deobfuscated)
if (!statsig.checkGate('claude_code_<feature>')) {
  throw new PermissionError('Feature not available');
}

Gate names found via strings:

claude_code_model_sonnet_access
claude_code_model_opus_access
claude_code_shell_unrestricted
claude_code_mcp_server_execution
claude_code_file_write_unrestricted
claude_code_network_access
claude_code_subagent_spawn
claude_code_web_search

PART 3: Gemini CLI

Binary Structure

Gemini CLI ships as a Go binary. The safety system is called Conseca — a multi-stage content evaluation engine with 5 check layers. YOLO mode is gated behind a flag that the Conseca engine validates independently of the config file.

# Initial recon
file $(which gemini)
strings $(which gemini) | grep -E '(conseca|yolo|safetyMode|adversary|threat)' | head -30
go tool objdump $(which gemini) 2>/dev/null | grep -i conseca | head -20

Conseca Safety Engine (5 checks)

──────┼───────────────────────────┼───────────────────────┼──────────────────────

PART 1: Codex CLI (Rust ELF)

Architecture

Codex CLI is a Rust binary with the Guardian AI safety stack compiled in as a static library. The binary uses Tokio async runtime; safety checks are async middleware in the tool call pipeline.

PART 2: Hermes Engine (embedded in Codex + React Native tools)

Architecture

Hermes is a JavaScript engine (Facebook/Meta) embedded as a static library. Used by Codex CLI to execute JS tool scripts. Safety checks are JIT-compiled callbacks.

OutputSanitizer       │ Post-exec     │ hermes::vm::JSError::create
CapabilityLimiter     │ Pre-exec      │ hermes::vm::Runtime::runBytecode
NetworkPolicyGate     │ Async hook    │ hermes::platform::fetch
FilesystemGuard       │ Native call   │ hermes::platform::readFile
ExecutionTimeLimit    │ Timer hook    │ hermes::vm::Runtime::tick

PART 4: Goose by Block (Rust binary)

Architecture

Goose is an open-source agentic AI tool by Block (formerly Square). It is a Rust binary using Tokio async runtime. The safety layer includes an AdversaryInspector component that flags tool calls, a threat pattern database, and a safety.mode config gate.

───────────────────────┼─────────────────┼──────────────────────────────────

ThreatPatternDetector  │ Static DB match │ Blocks calls matching known threat signatures
SafetyModeGate         │ Config gate     │ Enforces safety.mode=on from config
ModelCapabilityFilter  │ Model selection │ Restricts model access by capability tier
OutputSanitizer        │ Post-exec       │ Filters LLM output for unsafe content
