Journey Auth Agent Skill
Use as the auth build stage of the Butterbase journey, after journey-schema (and rls if separate). Implements the Auth section of 02-plan.md by delegating to auth-setup. Calls manage_oauth (configure) for providers and optionally manage_auth_config (configure_auth_hook, update_jwt). Skipped if the plan has no end-user auth.

7 sections, as written by the authorJourney: Auth
Stage 3c of the guided journey. Configure OAuth providers and (optionally) auth hooks.
When to use
- Dispatched by
journeywhencurrent_stage: auth. - Directly via
/butterbase-skills:journey-auth. - Skipped (annotated
(n/a)in00-state.md) if the plan has no end-user auth.
Preflight
If docs/butterbase/03-preflight.md is missing, older than 24 hours, or 00-state.md has app_id: null, invoke butterbase-skills:journey-preflight first. Wait for it to return successfully before proceeding.
Inputs
docs/butterbase/02-plan.md— the Auth section.docs/butterbase/00-state.md— forapp_id.
Procedure
- Refresh docs. Call
butterbase_docswithtopic: "auth". For provider-specific setup (Google/GitHub/Apple), also WebFetchhttps://docs.butterbase.ai/auth. Skip if cache is fresh.
- Read the Auth section of
02-plan.md. Print it back:"About to configure auth: providers=<list>, demo_user=<yes/no>. Proceed?". Wait foryes. - Invoke
butterbase-skills:auth-setupvia the Skill tool, passing the Auth plan andapp_id. The wrapped skill will prompt for each provider's client ID/secret and callmanage_oauth action: configure. If a demo user is requested, it seeds one viainsert_rowon the users table. - After it returns, run
manage_oauth action: getto confirm and print the redirect URLs the user must register with each provider. - Append one line to
docs/butterbase/04-build-log.md:
<ISO timestamp> auth manage_oauth ok
- Tick
- [x] authin00-state.md, setcurrent_stage:to the next unchecked stage. - Return to
journeyorchestrator (or ask"Continue to the next stage? (yes/no)").
Outputs
- Configured OAuth providers.
- Optional seed user.
- One line in
04-build-log.md.
Anti-patterns
- ❌ Echoing OAuth client secrets back to the user.
- ❌ Forgetting to give the user the provider-side redirect URL — auth will silently fail without it.
