reusable skill files:
- 4d-methodology.md: Core 4-phase clarification process
- nd-accommodations.md: Neurodivergent-friendly question patterns
- clarification-techniques.md: Anti-patterns and question templates
- escalation-patterns.md: Mode switching guidelines

+# Setup Workflow
+
+## Configuration Hierarchy
+
+| Level | Location | Contents |
+|-------|----------|----------|
+| System | `~/.config/claude/gitea.env` | API URL, token (shared across projects) |
+| Project | `.env` in project root | Org, repo name (per project) |
+
+## System Configuration
+
+### Check Existing
+
+```bash
+cat ~/.config/claude/gitea.env 2>/dev/null | grep -v "^#" | grep "GITEA_API_TOKEN=" && echo "OK" || echo "MISSING"
+```
+
+### Create New
+
+```bash
+mkdir -p ~/.config/claude
+cat > ~/.config/claude/gitea.env << 'EOF'
+# Gitea API Configuration
+GITEA_API_URL=https://your-gitea-server.com
+GITEA_API_TOKEN=PASTE_YOUR_TOKEN_HERE
+EOF
+chmod 600 ~/.config/claude/gitea.env
+```
+
+### Token Generation
+
+1. Gitea: Settings > Applications > Generate New Token
+2. Required scopes: `repo`, `read:org`, `read:user`
+
+## Project Configuration
+
+### Auto-Detect from Git Remote
+
+Extract organization:
+```bash
+git remote get-url origin 2>/dev/null | sed 's/.*[:/]\([^/]*\)\/[^/]*$/\1/'
+```
+
+Extract repository:
+```bash
+git remote get-url origin 2>/dev/null | sed 's/.*[:/]\([^/]*\)\.git$/\1/' | sed 's/.*\/\([^/]*\)$/\1/'
+```
+
+### Validate via API
+
+```bash
+source ~/.config/claude/gitea.env
+curl -s -o /dev/null -w "%{http_code}" -H "Authorization: token $GITEA_API_TOKEN" "$GITEA_API_URL/repos/<org>/<repo>"
+```
+
+| Code | Meaning |
+|------|---------|
+| 200 | Repository verified |
+| 404 | Not found - check org/repo names |
+| 401/403 | Auth issue - check token |
+
+### Create/Update .env
+
+```bash
+# New file
+cat > .env << EOF
+GITEA_ORG=<org>
+GITEA_REPO=<repo>
+EOF
+
+# Or append to existing
+echo "GITEA_ORG=<org>" >> .env
+echo "GITEA_REPO=<repo>" >> .env
+```
+
+## PR Review Settings (Optional)
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `PR_REVIEW_CONFIDENCE_THRESHOLD` | `0.7` | Minimum confidence to report |
+| `PR_REVIEW_AUTO_SUBMIT` | `false` | Auto-submit reviews to Gitea |
+
+## Sync Workflow
+
+When git remote changes:
+
+1. Detect new org/repo from git remote
+2. Compare with .env values
+3. Validate new values via API
+4. Update .env with sed:
+
+```bash
+sed -i 's/^GITEA_ORG=.*/GITEA_ORG=<new_org>/' .env
+sed -i 's/^GITEA_REPO=.*/GITEA_REPO=<new_repo>/' .env
+```
+
+## Shared with projman
+
+The Gitea MCP server is shared with the projman plugin. If projman is already configured, system-level setup can be skipped.
+
+Check for projman:
+```bash
+find ~/.claude ~/.config/claude -name "projman" -type d 2>/dev/null | head -1
+```
