Journey Storage

Use as the storage build stage of the Butterbase journey. Implements the Storage section of 02-plan.md by delegating to the storage skill. Calls manage_storage (update_config) for bucket setup; uploads are exercised at frontend integration time, not here. Skipped if the plan has no file uploads.

File contents

Journey: Storage

Stage 3d of the guided journey. Configure storage buckets/ACLs from the plan.

When to use

Dispatched by journey when current_stage: storage.
Directly via /butterbase-skills:journey-storage.
Skipped (annotated (n/a)) if the plan has no Storage section.

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 Storage section.
docs/butterbase/00-state.md — for app_id.

Procedure

Refresh docs. Call butterbase_docs with topic: "storage". For presigned URL patterns, also WebFetch https://docs.butterbase.ai/storage. Skip if cache is fresh.
Read the Storage section of 02-plan.md. Print it back: "About to configure storage: <buckets>. Proceed?". Wait for yes.
Invoke butterbase-skills:storage via the Skill tool, passing the Storage plan and app_id. The wrapped skill calls manage_storage action: update_config per bucket (visibility, max object size).
Smoke: request an upload URL via manage_storage action: upload_url and a matching download_url to confirm presigned URL minting works.
Append one line to docs/butterbase/04-build-log.md: <ISO timestamp> storage manage_storage ok
Tick - [x] storage in 00-state.md, set current_stage: to the next unchecked stage.
Return to journey orchestrator (or ask "Continue to the next stage? (yes/no)").

Outputs

Configured storage buckets.
One line in 04-build-log.md.

Anti-patterns

❌ Persisting s3_key in app data — always persist object_id. The wrapped skill handles this; do not override it.
