Keybindings Customizer

Use when the user wants to customize Claude Code keybindings, rebind shortcuts, add chords, or edit `~/.claude/keybindings.json` safely.

Use this skill for shortcut rebinding, unbinding, or chord creation.

Workflow

1. Read the current keybindings file first.
2. Merge changes instead of replacing the entire file.
3. Keep schema and docs fields intact.
4. Validate against reserved and non-rebindable shortcuts.
5. Explain any conflicts or terminal-level limitations.

Guardrails

• Never overwrite the full file blindly.
• Preserve unrelated existing bindings.
• Flag OS or terminal-reserved shortcuts before saving.

Example Requests

• Rebind the external editor shortcut.
• Add a chord to toggle todos without overwriting my keybindings file.

Inputs

• Requested key changes
• Existing keybindings file
• OS or terminal constraints

Outputs

• Merged keybinding config
• Conflict explanations

Success Criteria

• The file was merged, not clobbered.
• Reserved shortcuts were handled correctly.
• Schema and docs fields remain intact.

Non-Goals

• Whole-file replacement for a small binding change
