Set up Claude Code hooks to block dangerous git commands (push, reset --hard, clean, branch -D, etc.) before they execute. Use when user wants to prevent destructive git operations, add git safety hooks, or block git push/reset in Claude Code.
インストールする前に、エージェントに与えられる指示の中身を確認できます。
Sets up a PreToolUse hook that intercepts and blocks dangerous git commands before Claude executes them.
git push (all variants including --force)git reset --hardgit clean -f / git clean -fdgit branch -Dgit checkout . / git restore .When blocked, Claude sees a message telling it that it does not have authority to access these commands.
Ask the user: install for this project only (.claude/settings.json) or all projects (~/.claude/settings.json)?
The bundled script is at: scripts/block-dangerous-git.sh
Copy it to the target location based on scope:
.claude/hooks/block-dangerous-git.sh~/.claude/hooks/block-dangerous-git.shMake it executable with chmod +x.
Add to the appropriate settings file:
Project (.claude/settings.json):
{
"hooks": {
"PreToolUse": [
{
"matcher": "Bash",
"hooks": [
{
"type": "command",
"command": "\"$CLAUDE_PROJECT_DIR\"/.claude/hooks/block-dangerous-git.sh"
}
]
}
]
}
}
Global (~/.claude/settings.json):
{
"hooks": {
"PreToolUse": [
{
"matcher": "Bash",
"hooks": [
{
"type": "command",
"command": "~/.claude/hooks/block-dangerous-git.sh"
}
]
}
]
}
}
If the settings file already exists, merge the hook into existing hooks.PreToolUse array — don't overwrite other settings.
Ask if user wants to add or remove any patterns from the blocked list. Edit the copied script accordingly.
Run a quick test:
echo '{"tool_input":{"command":"git push origin main"}}' | <path-to-script>
Should exit with code 2 and print a BLOCKED message to stderr.

概要と使いどころ
Create or review an AGENTS.md file so coding agents get stable repo-local instructions: environment setup, testing, style, security boundaries, PR policy, and handoff rules. Use when a repo lacks durable agent guidance or when a custom harness needs a predictable context file.

Decision guide for delegating to caveman-style subagents. Tells the main thread WHEN to spawn `cavecrew-investigator` (locate code), `cavecrew-builder` (1-2 file edit), or `cavecrew-reviewer` (diff review) instead of doing the work inline or using vanilla `Explore`. Subagent output is caveman-compressed so the tool-result injected back into main context is ~60% smaller — main context lasts longer across long sessions. Trigger: "delegate to subagent", "use cavecrew", "spawn investigator/builder/reviewer", "save context", "compressed agent output".

Ultra-compressed communication mode. Cuts token usage ~75% by dropping filler, articles, and pleasantries while keeping full technical accuracy. Use when user says "caveman mode", "talk like caveman", "use caveman", "less tokens", "be brief", or invokes /caveman.

Ultra-compressed communication mode. Cuts token usage ~75% by speaking like caveman while keeping full technical accuracy. Supports intensity levels: lite, full (default), ultra, wenyan-lite, wenyan-full, wenyan-ultra. Use when user says "caveman mode", "talk like caveman", "use caveman", "less tokens", "be brief", or invokes /caveman. Also auto-triggers when token efficiency is requested.

Ultra-compressed commit message generator. Cuts noise from commit messages while preserving intent and reasoning. Conventional Commits format. Subject ≤50 chars, body only when "why" isn't obvious. Use when user says "write a commit", "commit message", "generate commit", "/commit", or invokes /caveman-commit. Auto-triggers when staging changes.
