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-durable 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 13d 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: Durable Objects

Stage 3i of the guided journey. Deploy stateful per-key actors.

When to use

  • Dispatched by journey when current_stage: durable.
  • Directly via /butterbase-skills:journey-durable.
  • Skipped (annotated (n/a)) if the plan has no Durable 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 Durable section.
  • docs/butterbase/00-state.md — for app_id.

Procedure

  1. Refresh docs. Call butterbase_docs with topic: "functions". For Durable Object class structure, also WebFetch https://docs.butterbase.ai/durable-objects. Skip if cache is fresh.

For each Durable Object class in the plan:

  1. Print: "About to deploy Durable Object: <name>. Proceed?". Wait for yes.
  2. Invoke butterbase-skills:durable-objects via the Skill tool with the DO spec and app_id. The wrapped skill calls manage_durable_objects action: deploy, sets env via set_env if needed.
  3. Verify with manage_durable_objects action: list and action: get.
  4. Append one line per DO to docs/butterbase/04-build-log.md: <ISO timestamp> durable manage_durable_objects <do-name> ok
  5. After all DOs are done, tick - [x] durable in 00-state.md, set current_stage: to the next unchecked stage.
  6. Return to journey orchestrator (or ask "Continue to the next stage? (yes/no)").

Outputs

  • Deployed Durable Object classes.
  • One line per DO in 04-build-log.md.

Anti-patterns

  • ❌ Sharing state across users via a single DO key — keys should be naturally per-room / per-user / per-resource.
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.
