Pick your task mode first

Mode What you're doing Where to go
New piece Building an integration for an app that has no piece yet Full 5-step workflow below
Add action / trigger An existing piece needs another operation or event Skip Steps 1–3. Open the existing piece, match its conventions (its common/ helpers, auth access, file naming, error handling), then jump to Step 4 IMPLEMENT and Step 5 WIRE & VERIFY. Bump the piece version.
Fix a bug An existing action/trigger misbehaves Reproduce → read the offending file and its common/ helpers → smallest fix that matches surrounding style → Step 5 VERIFY. Bump the piece version.

Golden rule for existing-piece modes: the piece you're editing is the source of truth, not these templates. If the piece already has a helper, a particular auth access pattern, or a way of shaping output, follow that. Reach into the reference files only for a pattern the piece doesn't already demonstrate.
