Application Frontend Cleanup Skill

HARD RULES (NEVER VIOLATE)

1. Never run any destructive command without explicit user confirmation. Every destructive step requires a separate confirmation.
2. Never delete the source/original project directory. Only delete the appfront-migrated/ folder (migration output) or the scaffolded project folder (create output). Never touch the original input project.
3. Never skip the undeploy step before deleting local files. Always undeploy from CF first (if the app was deployed), then clean up local files.

Phase 0 — Identify Project Type and Output Folder

Determine what kind of appFront project this is:

# Check for migration output folder
ls -d appfront-migrated/ 2>/dev/null && echo "MIGRATED" || echo "NOT_MIGRATED"

Check for mta.yaml to find the MTA ID

find . -maxdepth 3 -name "mta.yaml" 2>/dev/null

**Project type determination:**

| Condition | Project type | Local folder to delete |
|-----------|-------------|----------------------|
| `appfront-migrated/` exists alongside original project | Migration output | `appfront-migrated/` only |
| Neither applies | Unknown — ask user | Ask user which folder to remove |

Extract the MTA ID from the relevant `mta.yaml`:
```bash
grep "^ID:" appfront-migrated/mta.yaml 2>/dev/null || grep "^ID:" mta.yaml 2>/dev/null

Phase 1 — Undeploy from Cloud Foundry

Step 1 — Confirm undeploy

Ask the user:

Should I undeploy the appFront application <mta-id> from Cloud Foundry?

⛔ STOP if the user says no. Do not proceed to local file deletion without undeploying first (unless the user explicitly confirms the app was never deployed).

Step 2 — Confirm service deletion

Ask the user:

Should service instances and service keys also be deleted? ⚠️ This will permanently remove all provisioned services (e.g. app-front, xsuaa). This cannot be undone.

• No → undeploy only:

  cf undeploy <mta-id>
  

• Yes → undeploy and delete services:

  cf undeploy <mta-id> --delete-services --delete-service-keys
  

Wait for the undeploy to complete successfully before proceeding.

Phase 2 — Remove Local Output Folder

Only proceed after Phase 1 completes (or user confirms app was never deployed).

Ask the user:

Should I also delete the local <output-folder> directory?

If yes:

rm -rf <output-folder>

Where <output-folder> is:

• appfront-migrated/ — for migration output
• The scaffolded project folder — for apps created from scratch (confirm the exact folder name with the user before deleting)

---

Phase 3 — Cleanup Summary

Persist the summary before presenting it to the user:

mkdir -p .claude/appfront
date +"%Y%m%d-%H%M%S"

Write the full summary to .claude/appfront/<timestamp>-cleanup.md.
