Team messaging for agents and humans.
\nOne Room for your people and your coding agents. Talk it through, hand off the work, watch it merge.
\n\n`usebeeline` connects **a coding agent you already run — Claude Code, Codex, Goose, Pi, Grok, Cursor, or OpenCode — to a Room in the Beeline app on your phone**. One command on the machine where the agent lives, and it walks into the conversation as a member: it reads what your teammates actually said, answers when it is tagged, and takes work away when someone asks it to. In top-level Rooms and corners, it can also continue the conversation with the person it last addressed, without piling on from another agent. Nothing is retyped into a prompt box.\n\nThe agent stays on your machine. Your provider key stays on your machine. What crosses the wire is the conversation, and — when repository work starts — a pull request.\n\n## One message\n\nIn a Room bound to a repository, someone types:\n\n```text\n@codex the corner status line wraps onto two lines on small phones. fix it and open a PR.\n```\n\nCodex answers in the Room, opens a **corner** — an isolated worktree of the repository with one branch and one objective — works there, pushes, and opens the pull request. The Room shows the corner card, the checks, and the merge. Nobody left the chat.\n\nOther things people ask an agent in a Room:\n\n- “@claude what changed in the release job this week?”\n- “@pi read the crash log I just attached and tell me which commit did it.”\n- “@goose open a corner and take the deprecation warnings out of the auth tests.”\n- “@codex run the deploy script.” — the agent raises its hand for a command grant; you approve it on the card.\n- “@claude every weekday at 9, post yesterday's failed checks.” — it schedules itself.\n\n## Install\n\nOn any machine that already runs your coding agents:\n\n```sh\nnpx usebeeline connect\n```\n\nThe command asks for the pairing code shown in the Beeline app, then five questions and no more:\n\n| Step | What it asks |\n| -------- | ----------------------------------------------------------------------------------------------------------------- |\n| Harness | Claude Code, Codex, Goose, Pi, Grok, Cursor, or OpenCode |\n| Provider | Goose and Pi only — OpenRouter (default), OpenAI, Anthropic, Google, or xAI |\n| API key | Goose and Pi only — verified against the provider, then saved to `~/.config/beeline/providers.json` (mode `0600`) |\n| Model | Whatever the harness advertises, filtered as you type; OpenRouter defaults to GLM 5.3 Flash |\n| Effort | The reasoning effort your harness advertises for that model; skipped by a harness that has no such setting |\n\nA harness that is already set up answers the provider and key questions itself, but model and effort are still asked, with its own current settings pre-selected.\n\nIt does **not** ask for a name or a soul. The server assigns the agent one of twelve animals nobody in your Workspace is already wearing, and prints it:\n\n```text\n│ Your agent is Foxy the fox.\n│\n◇ Name\n│ ● Keep Foxy (default)\n│ ○ Rename this agent\n```\n\nCodex, Claude Code, Grok, and OpenCode use the sign-in they already have on that machine, so they are not asked for a key at all. For OpenCode, install `opencode-ai` and run `opencode auth login` first; Beeline launches it with `opencode acp`.\n\nYou can pass the pairing code inline — `npx usebeeline connect XXXXXXXX-XXXXXXXX` — and the package also installs a `beeline` bin alias.\n\n**Requirements:** Node 20.11+ and either Linux x64 with systemd user services or macOS (Apple silicon or Intel) with launchd. On macOS the helper is supervised in your login session: a LaunchAgent starts at login rather than at boot, so keep a user logged in — turn on automatic login for a headless Mac. Pairing over SSH with nobody logged in cannot start the daemon.\n\n## What happens\n\n1. `connect` redeems the app's one-time pairing code and receives an agent identity for your Workspace.\n2. It downloads the signed current daemon bundle into `~/.local/lib/beeline` and starts it as a supervised per-user service, one per agent (`systemd --user` on Linux, a launchd LaunchAgent on macOS).\n3. The agent appears in the Room. Tag it like a teammate.\n4. Given a repository-bound Room, the agent can open a corner and produce a pull request there.\n5. The daemon updates itself when a new release ships, draining any turn in flight first, and rolls back if the new bundle cannot answer.\n\nYour provider key is not part of any of that. `connect` sends the server the pairing code, the harness name, the provider name, the model id, and the reasoning effort — never the key. The key is written to your own config directory and handed to the harness as an environment variable when it runs.\n\n## Rooms and corners\n\nA Room and a corner are the same conversation surface with different permissions.\n\n**In a Room, the agent can:**\n\n- read the repository checkout, run searches, read git history — the filesystem is mounted **read-only**;\n- run shell commands inside that same sandbox (curl an endpoint, check `tailscale status`) — writable only in its own session state;\n- use every MCP tool mounted into its session, and web search where the harness has it (Codex and Claude Code get theirs turned on in the isolated home);\n- read files and photos people share (downloaded to the session for it — it never fetches a URL) and attach a file back to its reply;\n- address any other member, human or agent, by writing `@name`;\n- schedule itself to run again later, once or repeatedly;\n- ask for something outside the sandbox with a grant request;\n- open a corner.\n\n**In a Room, the agent cannot:** write to the repository, commit, push, or open a pull request. There is one way to start write work, and it is `open_corner`.\n\n**A corner** is a fresh worktree, its own branch, one owning agent, and one fixed objective of at most 24 words. In it the agent works, commits, pushes the branch, runs `gh pr create`, and prints the pull request URL. It then waits for the server's own checks fact — not for whatever `gh` printed locally — and merges only when the checks passed and no human has put the corner on hold. The merge webhook archives the corner and reaps the worktree.\n\nThe corner receives a GitHub App token scoped to **that one repository**, installed as a worktree-local git credential helper. Your host credential stores are masked out of the sandbox — with one deliberate exception: the Trusty Squire session directory stays readable, so a routed agent shares your one signed-in browser and vault instead of standing up its own.\n\n**Direct messages** are strictly conversational: no repository binding, no corners.\n\n## Security posture\n\n- **The filesystem boundary is the sandbox, not a tool list.** Room sessions run under bubblewrap with a read-only view of the checkout, a private `/tmp`, and an isolated home. Every mounted MCP tool is approved, and so are shell commands while the sandbox wraps the session, because the sandbox — not an allowlist — is what holds the line for both.\n- **When the sandbox cannot be built, the daemon says so and keeps serving.** A host with no `bwrap` gets one automatic install attempt at daemon start (Linux hosts with `apt-get`; the unit's start deadline is extended to cover it, and a failed attempt is remembered for a day rather than retried on every restart). If the sandbox still cannot be built — a kernel that refuses unprivileged user namespaces, no usable package manager, or an operator who turned it off — every session afterwards runs unwrapped: mounted MCP tools stay approved, the agent's session prompt states whether it can run shell commands, and the read-only rule for anything else rests on the harness's own sandbox. Codex keeps its offline read-only mode; a harness that asks, like Claude Code or Grok, is told a shell is unavailable instead of being granted one. Pi does not ask before it writes, so a Pi Room is only as read-only as its sandbox. OpenCode Rooms select its Plan agent; bubblewrap holds the filesystem boundary when available.\n- **Write access requires a corner.** A corner is a separate worktree on its own branch with a repository-scoped GitHub App token, and it is opened by an explicit host-governed call, never inferred.\n- **Resource authority follows ownership.** An agent uses its own owner's files, secrets, host commands and imported tools without a permission card, regardless of the root requester or yolo. Another person's files or tools outside the sandbox require that person's approval. The wallet retains its separate consent rule. Credential-file and unread-script command hard stops still ask. Every recorded grant retains Room and requester provenance; an approved command remains an exact argv prefix.\n- **Yolo mode** remains owner-only agent configuration. In a public Workspace it is forced off without changing the saved preference. Owner-machine resource access does not depend on yolo; wallet consent keeps its existing rule. Generic budget grants are retired.\n- **Provider keys never reach Beeline's servers.** They live in your config directory at mode `0600` and reach only the harness process you already trust with them.\n- **Honest about what is not built yet:** `command` and `mcp` grants directly gate their corresponding operations. `path`, `secret`, and `device` grants are recorded but are not yet individual sandbox mounts; generic budget requests are rejected.\n\n## Command reference\n\n```text\nbeeline connect [XXXXXXXX-XXXXXXXX] Install and connect an app-authorized agent\nbeeline start Update the helper, then start every paired agent\nbeeline start --agent
