Journey: Deploy verification

Stage 4 of the guided journey. Verify the deployed app actually works end-to-end.

When to use

• Dispatched by journey when current_stage: deploy.
• Directly via /butterbase-skills:journey-deploy.

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/00-state.md — for app_id, deployed_url.
• docs/butterbase/02-plan.md — for the function list to smoke.
• docs/butterbase/04-build-log.md — to know what shipped.

Procedure

0. Refresh docs. Call butterbase_docs with topic: "frontend". For end-to-end smoke patterns, also WebFetch https://docs.butterbase.ai/deploy. Skip if cache is fresh.

For each check, log a one-line result to 04-build-log.md. Halt on the first ✗ and ask the user to fix or skip.

1. Frontend reachable. If deployed_url is set, fetch it via Bash curl -sS -o /dev/null -w "%{http_code}" <url>. Expect 200. Log <ISO> deploy curl 200 ok or ... <code> fail.

2. Functions respond. For each function in the plan with HTTP trigger, call mcp__butterbase__invoke_function with a representative payload. Expect 2xx. Log per function.

3. Auth round-trip (if configured). If the plan included OAuth, prompt the user: "Open <deployed_url>, click 'Sign in with <provider>', and confirm you land logged-in. Did it work? (yes/no)". Log the answer.

4. Function logs clean. Call mcp__butterbase__manage_function action: get_logs for the most recent invocations. Show the user any error-level lines. Ask: "Anything concerning here? (no → continue, yes → fix and re-run)".

5. If all checks pass, tick - [x] deploy in 00-state.md, set current_stage: submit (if hackathon_mode: true) or current_stage: done (otherwise).

6. Return to journey orchestrator.

Outputs

• Multiple lines in 04-build-log.md.
• Updated 00-state.md.

Anti-patterns

• ❌ Treating a 200 from the frontend root as proof the app works — actually invoke a function.
• ❌ Skipping the auth round-trip check just because OAuth is configured server-side — judges will try to log in.
