+description: |
+  Use this skill whenever you need to interact with Gitea: creating pull requests,
+  listing issues, managing branches, checking PR status, or any other Gitea repo
+  operations in this project. The CLI tool is `tea`, already configured with login
+  `allanjsouza` pointing to `gitea.allanjsouza.cloud`. Use this skill any time the
+  user mentions PRs, pull requests, issues, Gitea, or asks you to open/create/list
+  anything on the remote repo — even if they don't say "tea" explicitly.

+
+# Gitea CLI Skill (`tea`)
+
+Gitea instance: `gitea.allanjsouza.cloud`  
+Login configured: `allanjsouza`  
+Repo remote: `ssh://git@gitea.allanjsouza.cloud:2222/allanjsouza/ctgwf.git`
+
+## Critical: No-TTY Mode
+
+`tea` tries to open an interactive TTY for some operations. This always fails in
+Claude Code. Always pass all required fields as flags — never rely on interactive
+prompts. When in doubt, check `tea <cmd> -h` and supply every required flag
+explicitly.
+
+## Creating a Pull Request
+
+```bash
+tea pulls create \
+  --title "feat: short description" \
+  --description "$(cat <<'EOF'
+## Summary
+- bullet 1
+- bullet 2
+
+## Test plan
+- [ ] item
+EOF
+)" \
+  --base main \
+  --head <current-branch>
+```
+
+Key flags:
+- `--base` — target branch (usually `main`)
+- `--head` — source branch (current feature branch; defaults to current if omitted)
+- `--title` — PR title (follow repo commit style: `type: description`)
+- `--description` — PR body (use a heredoc to avoid quoting issues)
+- `--assignees allanjsouza` — optionally assign to user
+- `--labels "label1,label2"` — optionally add labels
+
+**Always verify the current branch before creating a PR:**
+```bash
+git branch --show-current
+```
+
+**Push the branch first if not yet on remote:**
+```bash
+git push -u origin <branch>
+```
+
+## Listing PRs
+
+```bash
+tea pulls list                        # open PRs
+tea pulls list --state all            # all PRs
+tea pulls list --output json          # JSON output
+```
+
+## Listing Issues
+
+```bash
+tea issues list                       # open issues
+tea issues list --state all
+```
+
+## Other Useful Commands
+
+```bash
+tea pulls list --fields index,title,state,author,updated
+tea repo                              # show repo info
+tea branches list                     # list branches
+tea comment <issue-index> --body "…" # add comment
+```
+
+## Advanced API Operations (Review)
+
+`tea api` handles the construction of a JSON body when using `-f` (string) and `-F` (typed) flags. It also automatically replaces `{owner}` and `{repo}` placeholders with values from the current repository context.
+
+### Fetch PR Diff
+```bash
+tea api /repos/<owner>/<repo>/pulls/<index>.diff
+```
+
+### Submit a Review with Comments
+```bash
+tea api -X POST /repos/<owner>/<repo>/pulls/<index>/reviews \
+  -f "body=Automated Review" \
+  -f "event=COMMENT" \
+  -F "comments=@-" <<'EOF'
+[
+  {
+    "path": "app/models/user.rb",
+    "body": "Suggestion content",
+    "new_position": 42,
+    "old_position": 0
+  }
+]
+EOF
+```
+
+## Workflow for PR Creation
+
+1. Confirm all changes are committed: `git status`
+2. Push branch: `git push -u origin <branch>`
+3. Build PR title from commit history: `git log main.. --oneline`
+4. Create PR with `tea pulls create` (all flags explicit, no prompts)
+5. Return the PR URL from the `tea` output
