A controlled way to remove a Microsoft App from the cloud service. It does not delete the local project files.

Use it when permanently deleting a cloud-hosted Microsoft App while keeping the local workspace available for separate cleanup.

It helps prevent accidental deletion by showing the app details and requiring explicit confirmation, including a second confirmation if a forced removal is needed.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00028	$0.00919
Opus 5.5	$0.00011	$0.00368

Security

Grade C, and why

delete-app scanned grade C with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

📋 Shared Instructions: shared-instructions.md — Cross-cutting concerns. Two confirmations required; never auto---force.

Delete App

Removes the app from the service. The local workspace is NOT deleted by this skill — the user can clean it up afterward (this skill suggests the command but doesn't run it).

Workflow

Memory Bank → 2. Resolve App ID → 3. Verify with Show → 4. First Confirmation → 5. Try Non-Force Delete → 6. If Service Says Force Required: Second Confirmation → 7. Suggest Local Cleanup → 8. Update Memory Bank

Step 1: Check Memory Bank

Read memory-bank.md for app slug + GUID + environment.

Step 2: Resolve App ID

test -f ms.config.json && APP_ID=$(node -p "require('./ms.config.json').appId" 2>/dev/null) || true

If no ms.config.json, ask the user for the app slug or GUID. Optionally invoke /list-apps to discover.

Step 3: Verify with Show

Before the destructive call, fetch the app metadata so the user sees what they're about to delete:

BIN=ms
$BIN app show --app "$APP_ID" --json

Display: display name, slug, app GUID, environment, version, creation date, last modified, share count if available.

Step 4: First Confirmation

"About to delete the app <display-name> (slug <slug>, GUID <guid>) from environment <env-name>. This removes the app from the service for all users — playing the app stops working immediately. Continue?"

Wait for explicit yes. If no, STOP — do not delete.

Step 5: Try Non-Force Delete

$BIN app delete --app "$APP_ID" --non-interactive

ms app delete is idempotent: if the app is already gone (HTTP 204) it emits a warning rather than erroring. Treat both existed: true and existed: false outcomes as success.

Step 6: If Service Says Force Required

If the service returns a non-2xx with a message like "delete requires --force" (the app has active shares, child resources, etc.), DO NOT auto-add --force. Instead, ask a second confirmation:
