Guard Git

guard-git

Block dangerous git commands (push, force push, reset --hard, clean, branch -D, checkout/restore .) and enforce Conventional Commits & Branch Protection before an AI agent runs them. Installs hook scripts for Claude Code, Cursor, Cursor CLI, and Gemini CLI; documents Google Antigravity Terminal deny lists. Use when the user wants git safety hooks, to block git push or destructive git in agents, or to mirror the same policy across AI coding tools.

Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
3 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by danielvm-git on GitHub. Read the source before you install it.

Installation

Install the Guard Git AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
Enable the skill in any chat where you want it available.

Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/danielvm-git/bigpowers.git /tmp/bigpowers
mkdir -p .claude/skills
cp -r /tmp/bigpowers/skills/guard-git .claude/skills/guard-git

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Guard Git in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Guard Git on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Guard Git is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Guard Git

HARD GATE — HARD GATE — Before committing, verify: branch is not main/master, author is correct, git user is configured. Bad commits are hard to fix.

Installs a shared hook that blocks destructive git operations and enforces workflow discipline. Requires jq on the agent's PATH when the hook runs.

What gets blocked/enforced

Safety: git push --force, git reset --hard, git clean -f, git branch -D, git checkout ., git restore ..
Discipline: Blocks direct commits or pushes to protected branches (main, master) unless GIT_BIGPOWERS_LAND=1 (set only by scripts/land-branch.sh).
Allows: git push origin <feature-branch> for backup/CI; solo land push to main only inside land-branch.sh.
Standardization: Enforces Conventional Commits for all git commit commands.
Secrets: Blocks commits containing common secret patterns (sk-, ghp_, AKIA, xoxb-, -----BEGIN private keys) — see REFERENCE.md.

Quick start

Scope: ask project-only vs global (paths differ per product).
Write the hook bundle from REFERENCE.md into the client's hooks directory.
Run chmod +x on pre-tool-use.sh.
Merge the hook snippet from REFERENCE.md into the right settings file — do not wipe unrelated keys.
Verify with the tests in REFERENCE.md.

Client	Mechanism	Config
Claude Code	`PreToolUse` (Bash)	`.claude/settings.json` or `~/.claude/settings.json`
Cursor / Cursor CLI	`beforeShellExecution`	`.cursor/hooks.json` or `~/.cursor/hooks.json`
Gemini CLI	`BeforeTool` + `run_shell_command`	`.gemini/settings.json` or `~/.gemini/settings.json`
Google Antigravity	Built-in Terminal Deny list	Settings UI (no shell hook)

Modes (env on the hook command): GIT_GUARDRAILS_MODE is claude (default) or cursor → stderr + exit 2 on block. Set gemini for Gemini CLI → JSON decision on stdout.

Customization

To add or remove patterns or protected branches, edit pre-tool-use.sh.

Advanced

Full JSON examples, merge rules, Antigravity deny-list entries, and test commands: REFERENCE.md.

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Frequently asked questions

What does the Guard Git AI skill do?

Why use Guard Git on TypingMind?

Because you install it once and use it with any model. Guard Git is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Guard Git in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/danielvm-git/bigpowers/tree/main/skills/guard-git. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Guard Git?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Guard Git?

As many as you like. As long as a model supports skills, you can use Guard Git with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Guard Git AI skill free?

Yes. It is published on GitHub by danielvm-git under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
