It carries no authority…\n```\n\n## Why\n\nRunning several sessions on one repository means one of them regularly learns\nsomething another needs — a branch landed, a test is red, a question got\nanswered. Today that travels through you: read one terminal, retype it in\nanother.\n\nA message is text and nothing else. Never conversation history, never files.\nThat constraint is the design: it keeps the channel cheap, keeps it auditable,\nand makes it useless as a way to smuggle state between sessions.\n\n## What a session gets\n\n**Two tools.** `list_peers` shows the other sessions, their working directory,\nand whether each is idle, working, unresponsive, or not running.\n`message_peer` sends plain text to one of them by name. The model decides when\nto reach for them; you can also ask it to.\n\n**A mailbox that outlives the process.** The address is derived from the\nworking directory and pi's session id, so it survives restarts. Mail sent to a\nsession that is not running waits on disk and is read when the session resumes\nwith `pi -c`.\n\n**A receipt that means something.** The receiver deletes the letter when it\ntakes it, so the sender learns the difference between *delivered* and *queued*\nrather than being told a transport accepted the bytes.\n\n**A boundary on every delivery.** Each message arrives with a statement that it\ncame from a peer and carries no authority: it cannot approve anything, cannot\nchange configuration, and any slash command in it is inert text.\n\n## Install\n\n```bash\npi install npm:@shift-labs\u002Fpi-peer\n```\n\nNothing to enable. Every session registers itself on startup.\n\n## Use\n\nAsk for it in words; the model picks the tool.\n\n```text\nTell the session working on the dashboard that main moved.\nAsk the other sessions whether anyone is mid-migration.\n```\n\n`\u002Fpeers` prints the same listing `list_peers` returns.\n\n## Configuration\n\n| Variable | Default | Meaning |\n| --- | --- | --- |\n| `PI_PEER_INBOUND` | `accept` | `accept` delivers, `ask` prompts you per message, `refuse` drops everything |\n| `PI_PEER_DIR` | `~\u002F.pi\u002Fagent\u002Fpeers` | Where records and mailboxes live |\n\nThe directory is created `0700` and every file `0600`, so sessions belonging to\nother users on the machine cannot read or write them.\n\n## Remote: messaging your teammates' sessions\n\nPoint every machine on the team at one Redis server and the listing grows a\nsecond kind of peer:\n\n```\n ✓ list_peers   3 other pi sessions:\n     vex-2                 \u002FProjects\u002Fvex-2   [idle]\n     api@dan@dans-mbp      \u002Fhome\u002Fdan\u002Fapi     [working]\n     dashboard@noa@noas-mbp  \u002FUsers\u002Fnoa\u002Fdashboard  [not running]\n```\n\nA name containing `@` is a teammate's session on their machine. Message it\nexactly like a local one; mail for a session that is not running waits on the\nserver, up to 30 days, and is read when they resume.\n\n### Turning it on\n\nInteractively, from inside pi:\n\n```\n\u002Fpeer-remote\n```\n\nThe menu enables or disables the feature, sets the server URL, namespace,\nidentity, and the inbound policy for teammates' mail. Choices are written to\n`~\u002F.pi\u002Fagent\u002Fpi-peer.json` and applied to the running session immediately —\nno restart. (`ioredis` must be installed next to pi-peer; it is loaded only\nwhen remote is enabled.)\n\nOr from the environment, which **always overrides the file** — so scripts and\nCI jobs are never at the mercy of what was last clicked in a menu:\n\n```bash\nexport PI_PEER_REMOTE=redis          # or \"off\" to force-disable over the file\nexport PI_PEER_REDIS_URL=rediss:\u002F\u002F:password@redis.internal:6380\n```\n\n| Variable | Default | Meaning |\n| --- | --- | --- |\n| `PI_PEER_REMOTE` | *(unset)* = the file decides | `redis` forces on, `off` forces off |\n| `PI_PEER_REDIS_URL` | file's `url` | `redis:\u002F\u002F` or `rediss:\u002F\u002F` URL; auth and TLS travel in the URL |\n| `PI_PEER_NAMESPACE` | file's, else `pi-peer` | Keys are prefixed with this, so one server can carry several teams |\n| `PI_PEER_IDENTITY` | file's, else `user@hostname` | The qualifier teammates see after your session's name |\n| `PI_PEER_INBOUND_REMOTE` | file's, else `PI_PEER_INBOUND` | Separate `accept` \u002F `ask` \u002F `refuse` for mail from teammates |\n| `PI_PEER_CONFIG` | `~\u002F.pi\u002Fagent\u002Fpi-peer.json` | Where `\u002Fpeer-remote` keeps its choices |\n\nEverything degrades rather than breaks: a wrong setting, a missing `ioredis`,\nor an unreachable server is reported once at startup and local messaging\ncontinues exactly as if the setting were off.\n\n**What remote changes about trust.** A local message comes from your own\nsessions; a remote one comes from a teammate's machine. Deliveries say so, and\nthe boundary text warns the model that paths and commands in the message\ndescribe the sender's environment. Identity is *claimed, not proven* — anyone\nwho can reach the Redis can claim any name — so keep the server private (VPN,\nTLS, Redis ACLs) and consider `PI_PEER_INBOUND_REMOTE=ask` if you want to see\nteammates' messages before the model does.\n\n**What remote weakens, honestly stated.** Locally, “delivered” means the\nreceiving agent unlinked the file. Remotely, it means the receiving extension\npopped the letter and acknowledged it — a claim about their process, not about\nthe network in between. “Queued” still means what it always meant: the letter\nis spooled and waiting.\n\n## Limits\n\n**Plain text only**, capped at 32 KB. Send a summary and a path, not a payload.\n\n**One machine, unless remote is enabled.** Local delivery is a file landing in\na directory, so two sessions can reach each other exactly when they can see the\nsame filesystem. A container and its host cannot — unless both are pointed at\nthe same Redis (see below).\n\n**Loops are broken structurally.** Identical text from the same sender inside\nten seconds is dropped, a sender is throttled past eight messages in thirty\nseconds, and a backlog the agent has not read stops growing at fifty. Two\nagents answering each other therefore stop on their own.\n\n## How it works\n\nEach session writes a record into a shared directory and watches an inbox\nbeside it. Sending is a file appearing in someone else's inbox; receiving is\nthat file being taken and handed to the agent. There is no daemon, no socket,\nand no connection.\n\n[ARCHITECTURE.md](ARCHITECTURE.md) covers the design and the reasoning behind\nit.\n\n## Development\n\n```bash\nbun run check      # typecheck, lint, and the full suite — the gate\nbun test           # tests only\nbun run typecheck  # tsc --noEmit\nbun run format     # biome\n```\n\nThe test suite is the specification. Each case states the guarantee it pins and\nwhy that guarantee exists; read it before changing behaviour, and never weaken\na case to make a change pass.\n\n## Layout\n\n```\nsrc\u002Fpeer\u002F          the mechanism, with no pi dependency\n  registry.ts      addresses, records, presence, sweeping\n  mailbox.ts       depositing, draining, watching, receipts\n  transport.ts     the contract both transports meet; the local one\n  redis.ts         the remote transport, over a team's shared Redis\n  policy.ts        what to do with mail that arrives\n  format.ts        the text the model reads\nsrc\u002Fextension\u002F\n  index.ts         pi wiring: lifecycle, tools, delivery, transport composition\n```\n","pi-peer 是一个为 pi 命令行 AI 工具设计的轻量级会话通信扩展，支持本地及跨机器的终端会话间发现与纯文本消息传递。核心功能包括自动注册会话、`list_peers` 实时查看其他会话状态（工作目录、活跃度）、`message_peer` 发送无权限文本消息，并提供可靠投递语义（已送达\u002F已排队）与进程无关的持久化邮箱。所有消息明确标记为“来自对等会话”，不携带执行权限或状态变更能力，确保安全隔离。适用于多终端协同开发场景，如团队共享代码仓库时同步分支更新、测试状态或临时提醒，无需依赖外部聊天工具或复杂配置。",2,"2026-08-13 02:30:03","CREATED_QUERY"]
