@juli-os/agents — the execution substrate (L0)

The bottom layer of the juli-os ladder: a tmux-based agent session runtime. Everything an agent host needs to run sessions reliably and nothing it doesn't — zero npm dependencies, Node built-ins only.

What you get

• tmux client with confirmed delivery (sendTextConfirmed polls the input box reset — a swallowed Enter is re-sent, never the text), session provisioning, and a startup-time binary resolver that survives GUI-launched processes with a gutted PATH (the homebrew ENOENT class of failure)
• PTY attach — expect-wrapped interactive terminals for xterm-style frontends
• Provisioning dispatch — create-or-reuse session, cold-start claude pull-up, pane probes to tell "awaiting input" from "still working"
• Self-healing — snapshot/recover loop, zombie fingerprints, context gate (auto-compact on threshold with cooldown)
• Claude Code hooks — spec-driven install of Stop/SessionStart/PermissionRequest/ UserPromptSubmit/Notification/PostToolUse hooks so agent events flow back to your service
• Skills — markdown skill registry with prompt expansion
• ACP executor — protocol-level completion, preferred over tmux async when present
• Orchestrator & voice-call scaffolding — hook manager, command registry, session assessor, and the staged-plan (discuss → proposed → confirmed) call flow

Install

npm install @juli-os/agents

Node ≥ 22.5 (type-stripping). TypeScript source in this repo, compiled JS on npm.

Usage

import { createTmuxClient, resolveTmuxBin } from '@juli-os/agents';

const tmux = createTmuxClient({ socketPath: '/tmp/my.sock' });
if (!(await tmux.hasSession('worker-1'))) {
  await tmux.newSession('worker-1', '/srv/work');
}
// Confirmed delivery: polls the input box; a swallowed Enter is retried, not the text.
const res = await tmux.sendTextConfirmed('worker-1', 'claude "fix the failing test"');

CLI inspector (no side effects):

npx juli-agents bin                  # which tmux binary the runtime resolved
npx juli-agents sessions -S /tmp/my.sock
npx juli-agents has worker-1 -S /tmp/my.sock && echo alive

Where it sits

consumes	provides
nothing (zero deps)	tmux/PTY sessions, confirmed delivery, dispatch, hooks, snapshots, skills, ACP

Up the ladder: @juli-os/ledger records what agents do, @juli-os/routing decides where work goes, @juli-os/artifacts registers what they produce.

Locale note

Comments and a few operator-facing strings (e.g. the staged-plan voice prompt contract) are Chinese in this first release — they are runtime behavior, not chrome, and are translated via the export pipeline rather than by editing source.
