How to Prevent Claude Code from Overcharging When Your Commits Include 'OpenClaw'

Introduction

Using Claude Code for AI-assisted development can boost productivity, but a known quirk exists: if your commit messages reference the word "OpenClaw", the tool may either reject the request or apply an unexpected surcharge. This guide explains why this happens and provides clear, actionable steps to avoid these issues while still using similar terminology in your version control workflow. By following these steps, you can keep your commits descriptive and your costs predictable.

What You Need

• An active Claude Code subscription or API key
• Access to your project's Git repository
• Basic familiarity with commit message formatting
• A text editor or terminal for editing configuration files
• Optional: A test repository to try changes safely

Step-by-Step Instructions

Step 1: Understand the Trigger

The issue occurs when the word "OpenClaw" appears in any commit message. Claude Code's billing system treats this term as a trigger for premium features, possibly because it resembles a dependency name or a reserved keyword. To avoid charges, you must stop using that exact string in commits.

Step 2: Identify Existing Offending Commits

Search your repository for any commit messages containing "OpenClaw". Use the following command in your terminal:

git log --all --grep='OpenClaw' --oneline

Make a list of commit hashes and the messages. This helps you understand how often the trigger appears.

Step 3: Rewrite Recent Commit Messages (Local Only)

If the offending commits are not yet pushed to a shared remote, you can rewrite them. Use interactive rebase to edit messages:

1. Run git rebase -i HEAD~N where N is the number of recent commits to review. For older commits, use a commit hash: git rebase -i commit-hash^.
2. In the editor, change the word pick to reword for each commit that contains "OpenClaw". Save and close.
3. For each commit, Git will open an editor with the original message. Replace "OpenClaw" with an alternative such as "OpenClaw-compatible" or simply "claw" (without the prefix). Save and continue.
4. Finish the rebase with git rebase --continue after each message edit.

If the commits have already been pushed, do NOT rewrite them unless you coordinate with your team. Instead, skip to Step 5 to prevent future occurrences.

Step 4: Set Up a Commit Message Hook

Prevent the trigger from appearing in new commits by adding a pre-commit hook. Create a file named .git/hooks/pre-commit in your repository with the following content:

#!/bin/sh
commit_msg_file="$1"
if grep -qi 'OpenClaw' "$commit_msg_file"; then
  echo "ERROR: Commit message contains 'OpenClaw', which may trigger extra charges. Please replace it." >&2
  exit 1
fi

Make the hook executable with chmod +x .git/hooks/pre-commit.

For a team-wide solution, commit the hook script to a hooks folder in your repo and ask everyone to run git config core.hooksPath hooks.

Step 5: Use Environment Variables or Aliases

If you frequently write commits with terms similar to "OpenClaw", create a Git alias that replaces the word automatically in your commit command. Add this to your Git configuration:

git config --global alias.safecommit '!f() { local msg="$*"; msg="${msg//OpenClaw/OpenClaw-alt}"; git commit -m "$msg"; }; f'

Now use git safecommit "your message" and the alias will substitute any occurrence of "OpenClaw" with "OpenClaw-alt" before running the actual commit.

Step 6: Test with a Dry Run

Before deploying changes, run a dry commit in a test branch to confirm the fix works:

1. Create a test branch: git checkout -b test-openclaw-fix
2. Make a trivial change (e.g., edit a readme).
3. Stage the change and run git commit -m "Test OpenClaw message". Your hook should block it.
4. Now run git commit -m "Test OpenClaw-alt message" – this should succeed.
5. After verifying, delete the test branch: git branch -D test-openclaw-fix.

Step 7: Monitor Claude Code Billing

After implementing the fix, watch your Claude Code usage for a few days to ensure no unexpected charges appear. Log into the Claude dashboard and review the request logs. If you still see rejections, check if the term "OpenClaw" appears in file contents, branch names, or commit messages that might be read by the AI tool – sometimes logs include the full commit context.

Tips & Best Practices

Communicate with your team – If you share a repository, inform everyone about this potential charge trigger. Update your contribution guidelines to discourage usage of the term in commit messages.

Consider a comprehensive filter – In addition to the pre-commit hook, set up a server-side hook (e.g., in a CI pipeline) that rejects any push containing "OpenClaw" in commit messages. This provides a safety net.

Use alternative language – Instead of "OpenClaw", use terms like "opening claw mechanism", "claw-based logic", or simply reference the feature by a different internal code name.

Review your billing plan – If you frequently need to use the premium features that "OpenClaw" triggers, consider adjusting your Claude Code subscription to a plan that includes those features, so you’re not surprised by extra costs.

Keep your hooks updated – If Claude Code changes its trigger words in the future, you’ll need to update your hooks accordingly. Subscribe to official announcements or join user forums to stay informed.
