+# Gitea Workflow Automation
+
+## Trigger
+Use this skill when automating Gitea operations: creating issues, opening PRs, checking repository state, or integrating Gitea into CI/backlog workflows.
+
+## Prerequisites
+- `GITEA_URL` environment variable set (e.g., `https://forge.alexanderwhitestone.com`)
+- `GITEA_TOKEN` environment variable with a valid API token
+- `GITEA_USER` or explicit owner/org name
+- `curl` and `jq` available in the environment
+
+## Step-by-Step Workflow
+
+### 1. Verify Environment
+```bash
+: "${GITEA_URL?}" "${GITEA_TOKEN?}" "${GITEA_USER?}"
+echo "Gitea env OK"
+```
+
+### 2. List Issues in a Repository
+```bash
+curl -s -H "Authorization: token ${GITEA_TOKEN}" \
+  "${GITEA_URL}/api/v1/repos/${OWNER}/${REPO}/issues?state=open&limit=50" | jq '.[] | {number, title, state}'
+```
+
+### 3. Create an Issue
+```bash
+curl -s -X POST -H "Authorization: token ${GITEA_TOKEN}" \
+  -H "Content-Type: application/json" \
+  "${GITEA_URL}/api/v1/repos/${OWNER}/${REPO}/issues" \
+  -d "{\"title\":\"${TITLE}\",\"body\":\"${BODY}\",\"assignees\":[\"${ASSIGNEE}\"]}
+```
+- Escape newlines in `BODY` if passing inline; prefer a JSON file for multi-line bodies.
+
+### 4. Create a Pull Request
+```bash
+curl -s -X POST -H "Authorization: token ${GITEA_TOKEN}" \
+  -H "Content-Type: application/json" \
+  "${GITEA_URL}/api/v1/repos/${OWNER}/${REPO}/pulls" \
+  -d "{\"title\":\"${TITLE}\",\"body\":\"${BODY}\",\"head\":\"${BRANCH}\",\"base\":\"${BASE_BRANCH}\"}"
+```
+
+### 5. Check PR Status / Diff
+```bash
+curl -s -H "Authorization: token ${GITEA_TOKEN}" \
+  "${GITEA_URL}/api/v1/repos/${OWNER}/${REPO}/pulls/${PR_NUMBER}" | jq '{number, title, state, mergeable}'
+```
+
+### 6. Push Code Before Opening PR
+```bash
+git checkout -b "${BRANCH}"
+git add .
+git commit -m "${COMMIT_MSG}"
+git push origin "${BRANCH}"
+```
+
+### 7. Add Comments to Issues/PRs
+```bash
+curl -s -X POST -H "Authorization: token ${GITEA_TOKEN}" \
+  -H "Content-Type: application/json" \
+  "${GITEA_URL}/api/v1/repos/${OWNER}/${REPO}/issues/${NUMBER}/comments" \
+  -d "{\"body\":\"${COMMENT_BODY}\"}"
+```
+
+## Verification Checklist
+- [ ] Environment variables are exported and non-empty
+- [ ] API responses are parsed with `jq` to confirm success
+- [ ] Issue/PR numbers are captured from the JSON response for cross-linking
+- [ ] Branch exists on remote before creating a PR
+- [ ] Multi-line bodies are written to a temp JSON file to avoid escaping hell
+
+## Pitfalls
+- **Trailing slashes in `GITEA_URL`:** Ensure `GITEA_URL` does not end with `/` or double slashes break URLs.
+- **Branch not pushed:** Creating a PR for a local-only branch returns 422.
+- **Escape hell:** For multi-line issue/PR bodies, write JSON to a file with `cat <<EOF > /tmp/payload.json` and pass `@/tmp/payload.json` to curl instead of inline strings.
+- **Token scope:** If operations fail with 403, verify the token has `repo` or `write:issue` scope.
+- **Pagination:** Default limit is 30 issues; use `?limit=100` or paginate with `page=` for large backlogs.
+
+## Example: Full Issue Creation with File Body
+```bash
+cat <<'EOF' > /tmp/issue.json
+{
+  "title": "[Bezalel] Forge Health Check",
+  "body": "Build a diagnostic scanner for artifact integrity and permissions.\n\n- Detect .pyc without .py source\n- Detect world-readable sensitive files\n- Output JSON for CI consumption",
+  "assignees": ["bezalel"],
+  "labels": ["enhancement", "security"]
+}
+EOF
+curl -s -X POST -H "Authorization: token ${GITEA_TOKEN}" \
+  -H "Content-Type: application/json" \
+  "${GITEA_URL}/api/v1/repos/Timmy_Foundation/hermes-agent/issues" \
+  -d @/tmp/issue.json | jq '.number'
+```
