Debug Webhooks

Diagnose and fix webhook delivery issues for a Meta app.

Workflow

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

2. Get context. Ask the user for:

   • The app name or ID — if they give a name (or aren't sure of the ID), resolve it to an app_id via devtools_app_list (action list); if several apps match or it's ambiguous, show the candidates (name, ID, viewer role) and ask the user to pick
   • What's going wrong (not receiving events? wrong data? specific topic?)

   • devtools_webhook_list with action list_topics — all available topics (for comparison)

4. Diagnose. Check for common issues:
