What problem does it solve?

Claude Code Edit tool calls can fail silently when your repo uses tabs but the model patches with spaces.

Who is it for?

Indie devs on tab-indented codebases who rely on Claude Code Edit for daily implementation.

Skip if: Projects that only use space indentation or editors where this hook conflicts with custom PreToolUse chains.

BuildAgent skills & templates

Silent Edit failures block implementation mid-build, so this marketplace sits on Build as agent-side reliability tooling. Agent-tooling is the right shelf for hooks that normalize Claude Code Edit tool behavior before patches apply.

How it compares

Edit-tool hook fix, not a formatter skill or MCP integration.

Common Questions / FAQ

Who is Claude Tab Fix for?

Claude Code users whose repositories use tab indentation and who see failed or silent Edit operations from the agent.

When should I use Claude Tab Fix?

Enable it when you are in active build work and agent edits on tab-based files consistently do not apply.

How do I add Claude Tab Fix to my agent?

Add the WithHolm/Claude Tab Fix marketplace in Claude Code and turn on the Claude Tab Fix plugin so the PreToolUse hook runs on Edit.
