description: Create detailed git commit with comprehensive commit message
---

Please create a comprehensive git checkpoint with the following steps:

## Part 1: Git Checkpoint

1. **Initialize Git if needed**: Run `git init` if git has not been instantiated for the project yet.

2. **Analyze all changes**:

   - Run `git status` to see all tracked and untracked files
   - Run `git diff` to see detailed changes in tracked files
   - Run `git log -5 --oneline` to understand the commit message style of this repository

3. **Decide what will be staged** (do NOT stage yet):

   - Identify all tracked changes (modified/deleted) and untracked (new) files via `git status`.
   - Staging is done **atomically with the commit, under the repo lock, in step 5** — do not run a separate `git add` here. This prevents a concurrent session in a shared worktree (e.g. ClaudeTools) from having its dirty files swept into this checkpoint.

4. **Draft commit message body via Ollama** (documentation engine):

   ```bash
   # Resolve Ollama
   if curl -s -m 2 http://localhost:11434/api/tags >/dev/null 2>&1; then OLLAMA="http://localhost:11434"
   elif curl -s -m 3 http://100.92.127.64:11434/api/tags >/dev/null 2>&1; then OLLAMA="http://100.92.127.64:11434"
   else OLLAMA=""; fi

   # Capture diff summary for Ollama prompt
   { git diff --stat HEAD; echo "---"; git diff HEAD | head -200; } \
     > "C:/Users/guru/AppData/Local/Temp/checkpoint_diff.txt"

   # Ollama drafts the body; fallback to Claude if unavailable
   if [ -n "$OLLAMA" ]; then
     BODY=$(py -c "
import urllib.request, json
diff = open('C:/Users/guru/AppData/Local/Temp/checkpoint_diff.txt', encoding='utf-8').read()
prompt = 'Write a git commit message BODY only (not the summary line). Imperative mood. What changed and why. No filler. Under 150 words.\n\nDIFF:\n' + diff
body = json.dumps({'model':'qwen3:14b','messages':[{'role':'user','content':prompt}],'stream':False,'think':False}).encode()
res = json.loads(urllib.request.urlopen(urllib.request.Request('$OLLAMA/api/chat', body), timeout=60).read())
print(res['message']['content'])
")
   fi
   ```

   - **Summary line** (first line): Claude writes — 50-72 chars, imperative mood, from `git diff --stat`
   - **Body**: Ollama draft (Claude reviews); Claude writes directly if Ollama unavailable
   - **Footer**: `Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>`

5. **Execute the commit (locked)**: Write the final message (summary line + body + footer) to a temp file, then stage + commit **atomically under the repo's commit lock** so concurrent sessions can't interleave or get swept in:

   ```bash
   # MSG = path to the composed commit-message file; LOCK = the shared lock wrapper
   LOCK="${CLAUDETOOLS_ROOT:-/d/claudetools}/.claude/scripts/sync-lock.sh"
   bash "$LOCK" run bash -c 'git add -A && git commit -F "$1"' _ "$MSG"
   ```
   - The lock is scoped to the **current repo** (`git rev-parse --show-toplevel`/.git), so this serializes correctly whether the checkpoint is in ClaudeTools (shares the same lock as `/sync` and `/scc`) or in a project repo (its own lock). The wrapper errors out (exit 2) if you're not in a git repo.
   - If it **exits 75**, another commit/sync holds the lock — wait briefly and retry, or report "checkpoint deferred".
   - This is a **local commit only** (no push), matching checkpoint's purpose.
   - `$CLAUDETOOLS_ROOT` should be set per-machine; the `/d/claudetools` fallback is for this box only — on Mac/Linux it resolves from the env var.

## Part 2: Verify Git Checkpoint

6. **Verify commit**:
   - Confirm git commit succeeded by running `git log -1`
   - Report commit status to user

## Benefits of Git Checkpoint

**Git Checkpoint provides:**
- Code versioning
- Change history
- Rollback capability
- Complete project memory over time
- Collaboration support through detailed commit messages

## IMPORTANT

- Do NOT skip any files - include everything
- Make the commit message descriptive enough that someone reviewing the git log can understand what was accomplished
- Follow the project's existing commit message conventions (check git log first)
- Include the Claude Code co-author attribution in the commit message
