                            Claude runs to idle on Anthropic infra

/cma-webhook ◀── session.status_idled ◀───────┘
      │
      └──▶ sessions.retrieve → read metadata → chat.postMessage

The CMA session's metadata (slack_channel, slack_thread_ts) is the entire routing state.

Quickstart

bash

cd managed_agents/slack
bun install
claude

Then ask: "walk me through setting this up." Claude reads skill.md and drives the config — Slack app, Anthropic agent + webhook, env vars, bun run dev — in the order that actually works.
