App Health Check

App Health Check

Run a full audit of a Meta app and produce an actionable report.

Workflow

1. Start tracking. Before any other work, call devtools_skill_invocation with action start and skill_name app-health-check. Pass skill_name app-health-check on every devtools_* tool call in the following steps.

2. Identify the app. Ask the user for the app name or ID. If they give a name (or aren't sure of the ID), call devtools_app_list (action list) and resolve it to an app_id — match the name case-insensitively. If several apps match or it's ambiguous, show the candidates (name, ID, viewer role) and ask the user to pick. If they give a numeric ID, use it directly.

3. Collect data in parallel. Run all calls concurrently to minimize latency:

   • devtools_app with action basic_settings — app name, category, platform, contact info
   • devtools_app with action security — app secret rotation, allowed domains, data deletion URL
   • devtools_compliance with action status — open required actions, violations, recommendations
   • devtools_app_review with action status — current review state, pending submissions
   • devtools_api_usage with action rate_limits — current rate limit health
   • devtools_api_usage with action deprecations — deprecated APIs needing migration

4. Synthesize the report. Organize findings into these sections:

   Report Format

   App Overview

   • App name, ID, category, status

   Security

   • Highlight any issues: missing data deletion URL, stale app secret, overly broad domain allowlist
   • Flag if App Secret has not been rotated recently

   Compliance

   • List any open required actions with deadlines
   • List any active violations
   • Summarize recommendations

   App Review

   • Current review status
   • Any pending or rejected submissions
   • Permissions/features that still need review

   API Health

   • Rate limit status: report the overall_status field as returned — healthy, warning, critical, throttled, or unmetered
   • Usage at or above the 70% warning band, flagging 90%+ as critical
   • Deprecated APIs with severity and migration recommendations

   Action Items

   • Prioritized list of things to fix, ordered by severity (violations > required actions > recommendations > improvements)

5. Offer next steps. Suggest relevant follow-up skills:

   • /compliance-check for deeper compliance remediation
   • /app-review-prep if there are pending review requirements
   • /webhook-setup if webhooks aren't configured yet
   • /api-health for deeper API usage analysis and endpoint-level investigation

6. End tracking. After completing all preceding steps, call devtools_skill_invocation with action end and skill_name app-health-check.

Tips

• If any MCP call fails, report the failure in the relevant section rather than aborting the whole check.
• Always include the app ID in the report header for easy reference.
• For apps with no issues, keep the report short — don't pad with unnecessary detail.
