journey-agents

journey-agents is a skill for Claude Code from butterbase-ai/butterbase-skills. It costs 71 tokens per session (1,215 once invoked), scanned A, original, MIT.

A guided setup stage for creating the AI agents described in a Butterbase app plan. It registers the outside tool servers they need, validates each agent's workflow description, and runs a basic check.

In plain words
What is it for?
Use it when an app plan includes agents—automated assistants that can follow a defined workflow and use connected tools.
Why use it?
It ensures required tools are available before agents refer to them and catches configuration problems before use.

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-agents scanned grade A with 1 finding 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 12d 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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

- ❌ Smoking with `visibility: 'private'` and calling it good for a `public` agent. After the smoke, change visibility and re-test with an unauthenticated curl to confirm the public path works.

How it starts

The opening of the file, as written. The whole thing — 64 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Journey: Agents

Build the agents described in 02-plan.md. Order: MCP servers first (probe must pass before any agent references them) → agents → smoke runs.

When to use

  • Dispatched by journey when current_stage: agents.
  • Directly via /butterbase-skills:journey-agents.
  • Skipped (annotated (n/a)) if the plan lists no agents.

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 Agents section (names, purpose, tool list, visibility, MCP servers needed).
  • docs/butterbase/00-state.md — for app_id.
  • Any handcrafted spec files under agents/ in the project (preferred — version-controlled and survives clones).

Procedure

  1. Refresh docs. Call butterbase_docs with topic: "agents". If the cache (docs/butterbase/03b-docs-cache.md) already covers agents, skip.

  2. Register MCP servers first. For each MCP server in the plan:

    • Print: "Registering MCP server '<label>' at <url> (transport=<sse|http|streamable_http>). Proceed?". Wait for yes.
    • Call the MCP-servers registration route (or the dashboard's MCP Servers page if a wrapping MCP tool is not yet available — check butterbase_docs topic agents for the current preferred path).
    • Wait for probe result. If status: unhealthy, surface the error and ask the user to fix (URL, auth header, transport mismatch) before continuing. Do not create agents that reference an unhealthy server.

  3. Build each agent. For each agent in the plan, in order: a. Print: "About to build agent: <name> (visibility=<v>, tools=<n builtin / m mcp / k function>). Proceed?". Wait for yes. b. Invoke butterbase-skills:agents via the Skill tool with: agent name, intended behaviour, plan-derived tool list, model preference, visibility/limits. The wrapped skill drafts the graph_spec, writes it to agents/<name>.json in the project repo, and calls validate_agent_spec. c. If validation fails, surface the Zod issues and loop the agents skill to fix. d. Safety gate. If visibility != 'private' AND any node can reach a write tool (insert_row, update_row, delete_row, write_storage, or any read_write-mode MCP/function tool), explicitly ask: "This agent is reachable by <visibility> callers and can write data. Set safety_acknowledged=true? (yes / change to private / reduce tools)". Do not proceed silently. e. create_agent with the validated spec. f. Smoke: invoke_agent with a representative input. Poll get_agent_run until terminal. If the run errors, debug per the agents skill's debugging procedure; otherwise show the user the final output. g. Append one line per agent to docs/butterbase/04-build-log.md: <ISO timestamp> agents create_agent <agent-name> ok (run smoke=<run_id>)

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.

It adds 71 tokens to every session and 1,215 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
