+# Git Branching Workflow Extension
+
+Git repository initialization, feature branch creation, numbering (sequential/timestamp), validation, remote detection, and auto-commit for Spec Kit.
+
+## Overview
+
+This extension provides Git operations as an optional, self-contained module. It manages:
+
+- **Repository initialization** with configurable commit messages
+- **Feature branch creation** with sequential (`001-feature-name`) or timestamp (`20260319-143022-feature-name`) numbering
+- **Branch validation** to ensure branches follow naming conventions
+- **Git remote detection** for GitHub integration (e.g., issue creation)
+- **Auto-commit** after core commands (configurable per-command with custom messages)
+
+## Commands
+
+| Command | Description |
+|---------|-------------|
+| `speckit.git.initialize` | Initialize a Git repository with a configurable commit message |
+| `speckit.git.feature` | Create a feature branch with sequential or timestamp numbering |
+| `speckit.git.validate` | Validate current branch follows feature branch naming conventions |
+| `speckit.git.remote` | Detect Git remote URL for GitHub integration |
+| `speckit.git.commit` | Auto-commit changes (configurable per-command enable/disable and messages) |
+
+## Hooks
+
+| Event | Command | Optional | Description |
+|-------|---------|----------|-------------|
+| `before_constitution` | `speckit.git.initialize` | No | Init git repo before constitution |
+| `before_specify` | `speckit.git.feature` | No | Create feature branch before specification |
+| `before_clarify` | `speckit.git.commit` | Yes | Commit outstanding changes before clarification |
+| `before_plan` | `speckit.git.commit` | Yes | Commit outstanding changes before planning |
+| `before_tasks` | `speckit.git.commit` | Yes | Commit outstanding changes before task generation |
+| `before_implement` | `speckit.git.commit` | Yes | Commit outstanding changes before implementation |
+| `before_checklist` | `speckit.git.commit` | Yes | Commit outstanding changes before checklist |
+| `before_analyze` | `speckit.git.commit` | Yes | Commit outstanding changes before analysis |
+| `before_taskstoissues` | `speckit.git.commit` | Yes | Commit outstanding changes before issue sync |
+| `after_constitution` | `speckit.git.commit` | Yes | Auto-commit after constitution update |
+| `after_specify` | `speckit.git.commit` | Yes | Auto-commit after specification |
+| `after_clarify` | `speckit.git.commit` | Yes | Auto-commit after clarification |
+| `after_plan` | `speckit.git.commit` | Yes | Auto-commit after planning |
+| `after_tasks` | `speckit.git.commit` | Yes | Auto-commit after task generation |
+| `after_implement` | `speckit.git.commit` | Yes | Auto-commit after implementation |
+| `after_checklist` | `speckit.git.commit` | Yes | Auto-commit after checklist |
+| `after_analyze` | `speckit.git.commit` | Yes | Auto-commit after analysis |
+| `after_taskstoissues` | `speckit.git.commit` | Yes | Auto-commit after issue sync |
+
+## Configuration
+
+Configuration is stored in `.specify/extensions/git/git-config.yml`:
+
+```yaml
+# Branch numbering strategy: "sequential" or "timestamp"
+branch_numbering: sequential
+
+# Custom commit message for git init
+init_commit_message: "[Spec Kit] Initial commit"
+
+# Auto-commit per command (all disabled by default)
+# Example: enable auto-commit after specify
+auto_commit:
+  default: false
+  after_specify:
+    enabled: true
+    message: "[Spec Kit] Add specification"
+```
+
+## Installation
+
+```bash
+# Install the bundled git extension (no network required)
+specify extension add git
+```
+
+## Disabling
+
+```bash
+# Disable the git extension (spec creation continues without branching)
+specify extension disable git
+
+# Re-enable it
+specify extension enable git
+```
+
+## Graceful Degradation
+
+When Git is not installed or the directory is not a Git repository:
+- Spec directories are still created under `specs/`
+- Branch creation is skipped with a warning
+- Branch validation is skipped with a warning
+- Remote detection returns empty results
+
+## Scripts
+
+The extension bundles cross-platform scripts:
+
+- `scripts/bash/create-new-feature.sh` — Bash implementation
+- `scripts/bash/git-common.sh` — Shared Git utilities (Bash)
+- `scripts/powershell/create-new-feature.ps1` — PowerShell implementation
+- `scripts/powershell/git-common.ps1` — Shared Git utilities (PowerShell)

+
+# Auto-Commit Changes
+
+Automatically stage and commit all changes after a Spec Kit command completes.
+
+## Behavior
+
+This command is invoked as a hook after (or before) core commands. It:
+
+1. Determines the event name from the hook context (e.g., if invoked as an `after_specify` hook, the event is `after_specify`; if `before_plan`, the event is `before_plan`)
+2. Checks `.specify/extensions/git/git-config.yml` for the `auto_commit` section
+3. Looks up the specific event key to see if auto-commit is enabled
+4. Falls back to `auto_commit.default` if no event-specific key exists
+5. Uses the per-command `message` if configured, otherwise a default message
+6. If enabled and there are uncommitted changes, runs `git add .` + `git commit`
+
+## Execution
+
+Determine the event name from the hook that triggered this command, then run the script:
+
+- **Bash**: `.specify/extensions/git/scripts/bash/auto-commit.sh <event_name>`
+- **PowerShell**: `.specify/extensions/git/scripts/powershell/auto-commit.ps1 <event_name>`
+
+Replace `<event_name>` with the actual hook event (e.g., `after_specify`, `before_plan`, `after_implement`).
+
+## Configuration
+
+In `.specify/extensions/git/git-config.yml`:
+
+```yaml
+auto_commit:
+  default: false          # Global toggle — set true to enable for all commands
+  after_specify:
+    enabled: true          # Override per-command
+    message: "[Spec Kit] Add specification"
+  after_plan:
+    enabled: false
+    message: "[Spec Kit] Add implementation plan"
+```
+
+## Graceful Degradation
+
+- If Git is not available or the current directory is not a repository: skips with a warning
+- If no config file exists: skips (disabled by default)
+- If no changes to commit: skips with a message
