What it does
Journey Schema is an agent skill from butterbase-ai/butterbase-skills. Use as the schema build stage of the Butterbase journey, after journey-plan and journey-preflight. Implements the Tables section of 02-plan.md by delegating to schema-design, previewing the diff (manageschema dryrun) and applying it (manageschema apply). In hackathonmode, also folds in the RLS stage by invoking journey-rls inline before returning.
Its SKILL.md is about 720 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Databases, covering Database schema design. The repository describes itself as: Plugin for Butterbase.ai. The licence is MIT.
When your agent uses it
- Tasks that involve Database schema design
Example prompts
- “/journey-schema”
Workflow steps
8 steps, taken from the first numbered list in SKILL.md.
- Refresh docs. Call butterbase_docs with topic: "schema". If the plan calls for advanced schema features (vectors, partial indexes…
- Read the Tables section of 02-plan.md. Print it back: "About to apply schema: . Proceed?". Wait for yes.
- Invoke butterbase-skills:schema-design via the Skill tool, passing the Tables section and app_id. The wrapped skill will build the…
- After it returns, optionally run a sanity manage_schema action: get and show the user the live shape.
- Hackathon mode only: if 00-state.md has hackathon_mode: true, also invoke butterbase-skills:journey-rls inline now. After it returns, mark…
- Append one line to docs/butterbase/04-build-log.md (create if absent)
- Tick - [x] schema in 00-state.md, set current_stage: to the next unchecked stage (typically rls outside hackathon mode, otherwise the…
- Return to journey orchestrator (or, if invoked directly, ask: "Continue to the next stage? (yes/no)").
What it can do on your machine
Read from SKILL.md and the folder at commit aa8ae69. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
docs.butterbase.ai
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Journey Schema loads about 720 tokens when it runs. Until then it costs about 92 tokens; SKILL.md has 309 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- Use as the schema build stage of the Butterbase journey, after journey-plan and journey-preflight. Implements the Tables section of 02-plan.md by delegating to schema-design, previewing the diff (manage_schema dry_run) and applying it (manage_schema apply). In hackathon_mode, also folds in the RLS stage by invoking journey-rls inline before returning.
Journey: Schema
Stage 3a of the guided journey. Apply the declarative table definitions from the plan.
When to use
- Dispatched by
journeywhencurrent_stage: schema. - Directly via
/butterbase-skills:journey-schema.
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 Tables section.docs/butterbase/00-state.md— forapp_id,hackathon_mode.
Procedure
Refresh docs. Call
butterbase_docswithtopic: "schema". If the plan calls for advanced schema features (vectors, partial indexes, generated columns), also WebFetchhttps://docs.butterbase.ai/schema. Skip this step ifdocs/butterbase/03b-docs-cache.mdwas written less than 30 minutes ago and already coversschema.Read the Tables section of
02-plan.md. Print it back:"About to apply schema: <N tables>. Proceed?". Wait foryes.Invoke
butterbase-skills:schema-designvia the Skill tool, passing the Tables section andapp_id. The wrapped skill will build the declarative schema, dry-run it withmanage_schema action: dry_run, then apply withaction: applyafter user approval of the diff.After it returns, optionally run a sanity
manage_schema action: getand show the user the live shape.Hackathon mode only: if
00-state.mdhashackathon_mode: true, also invokebutterbase-skills:journey-rlsinline now. After it returns, mark the rls checkbox as(folded)in00-state.mdrather than leaving it unchecked.Append one line to

- [x] schemain00-state.md, setcurrent_stage:to the next unchecked stage (typicallyrlsoutside hackathon mode, otherwise the stage after rls), bumplast_updated.Return to
journeyorchestrator (or, if invoked directly, ask:"Continue to the next stage? (yes/no)").
Outputs
- Live schema in the Butterbase app.
- One line in
04-build-log.md. - Updated
00-state.md.
Anti-patterns
- ❌ Calling
manage_schema action: applywithout showing the user the dry-run diff. - ❌ Forgetting
_drop:/_dropColumns:are needed for destructive changes — never set them without explicit user confirmation. - ❌ Forgetting the hackathon-mode RLS fold.
