 ## Security & Configuration Tips
 Do not commit secrets. Copy `.env.example` to `.env` locally.  
 Restrict Slack access with `SLACK_ALLOWED_USER_ID` and `SLACK_ALLOWED_CHANNEL_ID` before running in shared workspaces.
+
+## Git & Gitea Workflow Notes
+Use `tea` (Gitea CLI), not `gh`.
+
+Hard rule:
+- Never implement changes, stage files, or commit on `main`.
+- Always create/use a feature branch first, and merge via PR.
+
+- Check login:
+  - `tea login ls`
+  - `tea whoami`
+- Create/update feature branch:
+  - `git checkout -b <branch>` (or `git checkout <branch>`)
+  - `git add <files>`
+  - `git commit -m "<message>"`
+- Push to Gitea:
+  - Normal: `git push -u origin <branch>`
+  - If HTTP username prompt fails in this environment, use the token from `~/.config/tea/config.yml`:
+    - `TOKEN=$(sed -n 's/^[[:space:]]*token: //p' ~/.config/tea/config.yml | head -n1)`
+    - `git push "http://agentson:${TOKEN}@localhost:3000/jihoson/LazyEnter.git" <branch>`
+- After token-based push, ensure tracking is on `origin/<branch>` (not token URL):
+  - `git fetch origin <branch>:refs/remotes/origin/<branch>`
+  - `git branch --set-upstream-to=origin/<branch> <branch>`
+- Create PR on Gitea:
+  - `tea pr create --base main --head <branch> --title "<title>" --description "<body>"`
+  - If PR body includes backticks (`` ` ``), slash commands, or markdown that can be shell-expanded, do not pass it directly in double quotes.
+  - Preferred safe flow:
+    - `cat > /tmp/pr_body.md <<'EOF'` ... `EOF`
+    - `tea pr create --base main --head <branch> --title "<title>" --description "$(cat /tmp/pr_body.md)"`
+  - If the body is malformed after creation, patch it with API:
+    - `tea api -X PATCH repos/{owner}/{repo}/pulls/<number> -F body=@/tmp/pr_body.md`
+- Sync local main:
+  - `git checkout main`
+  - `git pull --ff-only`
+  - When user confirms the PR is merged, always run this sync immediately to keep local `main` up to date before any next task.
+
+Safety:
+- Do not commit or print tokens in logs/docs.
+- Keep unrelated local files (for example `uv.lock`) out of PRs unless intentionally changed.
