-Updates project configuration when the git remote URL has changed.
+## Purpose
 
-**Use this when:**
-- Repository was moved to a different organization
-- Repository was renamed
-- Git remote URL changed
-- SessionStart hook detected a mismatch
+Updates config when git remote URL changed.
 
----
+**Use when:** Repo moved/renamed, SessionStart detected mismatch
 
-## Step 1: Verify System Configuration
+## Workflow
 
-```bash
-cat ~/.config/claude/gitea.env 2>/dev/null | grep -v "^#" | grep -v "PASTE_YOUR" | grep "GITEA_API_TOKEN=" && echo "SYSTEM_OK" || echo "SYSTEM_MISSING"
-```
+Execute `skills/setup-workflow.md` Sync Workflow:
 
-**If SYSTEM_MISSING:** Run `/initial-setup` first.
-
----
-
-## Step 2: Read Current .env
-
-```bash
-cat .env 2>/dev/null
-```
-
-Extract `GITEA_ORG` and `GITEA_REPO` values.
-
-**If missing:** Redirect to `/project-init`.
-
----
-
-## Step 3: Detect Git Remote
-
-```bash
-git remote get-url origin 2>/dev/null
-```
-
-Extract organization and repository from URL.
-
----
-
-## Step 4: Compare Values
-
-| Scenario | Action |
-|----------|--------|
-| **Match** | "Configuration in sync" - exit |
-| **Mismatch** | Show diff, proceed to validation |
-
----
-
-## Step 5: Validate via Gitea 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/<NEW_ORG>/<NEW_REPO>"
-```
-
-| Code | Action |
-|------|--------|
-| **200** | Verified - proceed to update |
-| **404** | Not found - ask to confirm |
-| **401/403** | Permission issue - warn |
-
----
-
-## Step 6: Confirm and Update
-
-Use AskUserQuestion to confirm, then update .env:
-
-```bash
-sed -i 's/^GITEA_ORG=.*/GITEA_ORG=<NEW_ORG>/' .env
-sed -i 's/^GITEA_REPO=.*/GITEA_REPO=<NEW_REPO>/' .env
-```
-

-## Step 7: Confirm Success

+1. Verify system config exists
+2. Read current .env values
+3. Detect org/repo from git remote
+4. Compare - if match, exit; if mismatch, continue
+5. Validate new values via API
+6. Update .env with sed
+7. Display confirmation from `skills/output-formats.md`
