journey-docs

journey-docs is a skill for Claude Code from butterbase-ai/butterbase-skills. It costs 62 tokens per session (531 once invoked), scanned A, original, MIT.

A preparation stage that reads an app plan and loads the relevant Butterbase documentation before building begins. It stores short documentation summaries for later stages to use.

In plain words
What is it for?
Use it after project preflight and whenever the plan changes, especially for apps using databases, authentication, storage, functions, AI, search, real-time features, payments, or integrations.
Why use it?
It reduces the chance of implementing an API incorrectly because the build stages start with current guidance for the planned capabilities.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

journey-docs scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Journey Docs Gate

A short, mechanical priming step. The goal is that every downstream stage starts with the relevant docs already in the conversation, so the model doesn't invent API shapes.

When to use

Invoke automatically after journey-preflight returns. Also invoke standalone (/butterbase-skills:journey-docs) any time the user changes the plan or you realize a stage is using a capability you haven't refreshed this session.

Procedure

  1. Read the plan. Open docs/butterbase/02-plan.md. Identify every Butterbase capability in use (Tables → schema; RLS → auth; Auth → auth; Storage → storage; Functions → functions; AI → ai; RAG → rag; Realtime → realtime; Durable → functions; Frontend → frontend; Integrations → integrations; Substrate → substrate; Payments → billing).

  2. Call butterbase_docs per topic. For each unique topic from step 1, call butterbase_docs with that topic argument. Skip duplicates.

  3. Write the cache file. Create docs/butterbase/03b-docs-cache.md with this structure:

    ---
    primed_at: <ISO timestamp>
    topics: [<comma-separated list>]
    ---
    
    # Docs Cache
    
    ## <topic-1>
    <one-paragraph summary of what the MCP doc says — key endpoints, common patterns, gotchas>
    URL: https://docs.butterbase.ai/<area>
    
    ## <topic-2>
    ...
    
  4. Update 00-state.md. Tick the docs row.

  5. Return. One-line summary: "Primed docs for: schema, auth, storage, functions. Cache at docs/butterbase/03b-docs-cache.md."

Anti-patterns

  • ❌ Calling butterbase_docs with topic: "all". Burns context. Call once per relevant topic instead.
  • ❌ Skipping the cache file. Other stages re-read it; in-memory only doesn't survive context compression.
  • ❌ Calling for topics not in the plan. We're priming, not exhaustive.
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
