Claude Code - Auto Mode Fixed

Automated patcher that enables Auto Mode (claude --enable-auto-mode) in Claude Code for users running through a proxy (ANTHROPIC_BASE_URL).

A GitHub Actions workflow checks for new Claude Code releases every 6 hours, patches the binaries for all platforms, and publishes them as a GitHub Release.

---

Why is this needed?

Claude Code gates Auto Mode behind a server-side feature flag (tengu_auto_mode_config) fetched via GrowthBook remote evaluation at api.anthropic.com.

When you point Claude Code at a proxy (via ANTHROPIC_BASE_URL), the GrowthBook client cannot establish trust with Anthropic's servers. It falls back to a hardcoded default: "disabled". This triggers the circuit breaker:

auto mode temporarily unavailable

This repo patches that default from "disabled" to "enabled".

How the patch works

Inside the compiled binary, the minified JS contains a function parseAutoModeEnabledState that validates the feature flag value:

function XX(Y) {
  if (Y === "enabled" || Y === "disabled" || Y === "opt-in") return Y;
  return DEFAULT_VAR;  // DEFAULT_VAR = "disabled"
}

The patcher locates DEFAULT_VAR by anchoring on the unique "opt-in" string literal, then replaces the declaration (same byte length):

VARNAME="disabled";var  ->  VARNAME="enabled"; var

When GrowthBook skips the fetch (no trust), the function now returns "enabled" instead of "disabled", and the circuit breaker stays off.

Real Anthropic users are unaffected -- their value comes from the live GrowthBook response.

Downloads

Go to Releases and grab the binary for your platform:

Platform	File
Linux x64	claude-linux-x64
Linux ARM64	claude-linux-arm64
Linux x64 (musl/Alpine)	claude-linux-x64-musl
macOS x64 (Intel)	claude-macos-x64
macOS ARM64 (Apple Silicon)	claude-macos-arm64
Windows x64	claude-windows-x64.exe

Installation

Replace your existing claude binary:

# Linux / macOS
cp claude-linux-x64 ~/.local/bin/claude   # adjust filename for your platform
chmod +x ~/.local/bin/claude

# Windows
copy claude-windows-x64.exe %USERPROFILE%\.local\bin\claude.exe

Then launch Claude Code with auto mode:

claude --enable-auto-mode

Manual patching

python scripts/patch_binary.py /path/to/claude /path/to/claude-patched

Workflow

The GitHub Actions workflow (.github/workflows/patch-and-release.yml):

1. Runs every 6 hours (+ manual dispatch)
2. Reads the latest version from the GCS distribution bucket
3. Downloads platform binaries from GCS (Linux, macOS) and npm (Windows)
4. Applies the patch via scripts/patch_binary.py
5. Publishes a GitHub Release with all patched binaries
