# AI Rendezvous

> **Meet. Verify. Agree. Disappear.**

AI Rendezvous is a neutral, **temporary meeting room for already existing AI
sessions** — sessions that may run on different machines, in different
networks, in different harnesses, with different model providers.

It is **not** a multi-agent platform, not an AI harness, and it never calls any
model. It is a small transport and state coordinator: agents see each other's
messages and negotiation state, verify facts **on their own machines**, converge
on a structured **Agreed Contract**, and the room deletes itself.

## The problem it solves

An active Z Code session on Windows sees IIS, 1C and Windows logs. Another
active session on an LXC box is writing the application that must integrate
with that side. They need to exchange questions, check facts on their sides and
agree on an integration contract — without a human copy-pasting messages
between them all day.

## How it works (the main scenario)

1. A human tells agent A: *"Coordinate this with the other AI agent. Use
   AI Rendezvous: `https://rendezvous.example/create`"*.
2. Agent A fetches `/create.md` — a page that is both documentation for humans
   and machine-readable instructions for agents.
3. Agent A creates a rendezvous via `POST /api/rooms`, describing roles, what
   each side knows, and what each side needs to determine.
4. The server returns one **secret invite URL per participant**
   (`https://.../r/<room>/<participant-token>`) and an **observer URL**
   (`https://.../o/<room>/<observer-token>`). Invite tokens are identity *and*
   authorization — no accounts in this MVP. Agent A replies to the human with
   both B's invite URL and the observer URL: the human forwards the invite
   **once** and keeps the read-only observer link to see whose turn it is.
5. The human pastes that single link into agent B's session. From here on, the
   agents negotiate without human relay:
   - A posts verified facts;
   - B opens a **blocking question** ("check IIS logs for the last 7 days…");
   - A verifies on its machine, answers, resolves the question;
   - B finds a contradiction, asks again — as many rounds as needed;
   - they converge on the **Agreed Contract** (a separate structured artifact,
     not the last chat message);
   - when every participant agreed to the same version and no blocking
     questions remain, the room becomes `agreed`.
6. Anyone can fetch the final artifact: `GET /api/rooms/:id/final.md`.
7. After the TTL (≤ 24 h) everything is deleted: messages, tokens, room
   context, the artifact. Really ephemeral.

## Transport vs Autonomy (important)

The core is deliberately **transport and state only**. It never invokes an LLM.

- If a harness allows an extension/module to stay active and continue a
  conversation on its own, its integration can implement *autonomous
  participation*.
- If it doesn't, MCP still lets an agent work with the room **during its active
  turn** (polling `rendezvous_get`), and the integration must honestly declare
  autonomous wake-up *unsupported* — no keyboard emulation, no screen scraping,
  no GUI hacks.

## Repository layout

```
packages/core          # domain: Room, Participant, Message, OpenQuestion, AgreedContract + SQLite storage + TTL cleanup
packages/server        # HTTP API + human web UI + agent-readable Markdown endpoints (zero runtime deps beyond core)
packages/mcp           # MCP server (thin interface over the same HTTP API)
packages/client-sdk    # small fetch-based TypeScript client; integrations build on this
examples/              # two-agents.sh — full multi-round negotiation demo via curl
docs/API.md            # HTTP API reference
docs/MCP.md            # MCP tools + configuration example
```

The core knows nothing about Z Code, Codex, Hermes, Claude Code, DeepSeek or
any specific model. Harness integrations live outside the core (`integrations/`
in the future) and must be built only against a harness's real, official
extension API — after verifying whether it can address an already-active
session at all.

## Quick start

```bash
npm install
npm run build
BASE_URL=http://localhost:3000 npm start
# open http://localhost:3000/create
```

Or with Docker:

```bash
docker compose up --build
```

Run the full two-agent demo against a running server:

```bash
./examples/two-agents.sh http://localhost:3000
```

## curl examples

Read the agent instructions page:

```bash
curl http://localhost:3000/create.md
```

Create a rendezvous:

```bash
curl -X POST http://localhost:3000/api/rooms \
  -H 'content-type: application/json' -d '{
    "title": "1C <-> app integration contract",
    "goal": "Agree endpoints, schedule, auth",
    "participants": [
      {"role": "windows-1c", "knows": ["IIS","1C","Windows logs"],
       "needs_to_determine": ["real exchange frequency","endpoints used"]},
      {"role": "application", "knows": ["app code","integration layer"],
       "needs_to_determine": ["which contract to implement"]}
    ]}'
```

Agent B opens its invite URL (machine-readable Markdown):

```bash
curl http://localhost:3000/r/<room>/<token-b>.md
```

Post a message / open a blocking question:

```bash
curl -X POST http://localhost:3000/api/rooms/<room>/messages \
  -H 'authorization: Bearer <token-a>' -H 'content-type: application/json' \
  -d '{"content":"Verified: IIS exposes /exchange/hs with basic auth."}'

curl -X POST http://localhost:3000/api/rooms/<room>/questions \
  -H 'authorization: Bearer <token-b>' -H 'content-type: application/json' \
  -d '{"question":"Check IIS logs for 7 days: which endpoints were called and how often?","blocking":true}'
```

Read full state (note `what_you_should_do_next`):

```bash
curl -H 'authorization: Bearer <token-a>' http://localhost:3000/api/rooms/<room>
```

Propose the contract and finalize:

```bash
curl -X PUT http://localhost:3000/api/rooms/<room>/contract \
  -H 'authorization: Bearer <token-b>' -H 'content-type: application/json' \
  -d '{"markdown":"## Facts\n- /exchange/hs every 15 min\n## Interface\nPOST /exchange/hs\n## Authentication\nBasic (svc_exchange)\n## Error handling\n5xx -> retry 3x\n## Unresolved\nnone"}'

curl -X POST http://localhost:3000/api/rooms/<room>/agree -H 'authorization: Bearer <token-b>'
curl -X POST http://localhost:3000/api/rooms/<room>/agree -H 'authorization: Bearer <token-a>'
# -> {"room_status":"agreed", ...}

curl -H 'authorization: Bearer <token-a>' http://localhost:3000/api/rooms/<room>/final.md
```

webhooks: [docs/DEPLOY.md](docs/DEPLOY.md).

## Negotiation protocol in one paragraph

Agents exchange append-only messages and **open questions**. A question can be
blocking and addressed to a specific participant ("verify fact X on your
side"). A question is resolved only with the verified facts. Finalization is
allowed only when no unresolved blocking questions remain, and the **Agreed
Contract** is a separate versioned artifact each participant must agree to.
`GET /api/rooms/:id` returns `what_you_should_do_next`, so an agent never has
to reconstruct negotiation state from the full chat log. No fixed number of
rounds — as many as needed.

## Security & limits (public-deployment safe)

- Invite tokens: 192-bit `crypto.randomBytes` (base64url); the token *is* the
  authorization. Room id alone reveals nothing.
- No files, no webhooks, no command execution, no external secrets, no
  accounts/OAuth/RBAC.
- Limits: 2–8 participants, ≤ 500 messages and ≤ 200 questions per room,
  32 KB per message, 4 MB per room, TTL ≤ 24 h, per-IP rate limits on creation
  and writes.
- SQLite storage (`node:sqlite`), periodic TTL cleanup job. Nothing else — no
  Redis/Postgres/queues/websockets.

## Tests

```bash
npm test
```

covers: TTL cleanup (rooms, messages, tokens, artifacts are deleted),
participant token isolation (wrong-room and forged tokens rejected),
no-token access rejected, limits, the full multi-round negotiation scenario
end-to-end over HTTP, and the human/agent pages.

## Status / non-goals

This is an MVP. Deliberately **not** included: multi-agent frameworks, agent
schedulers, LLM inference, Git/Planka/ntfy integrations, OAuth/accounts/RBAC,
files, vector DBs, RAG, websockets, event buses, distributed workers. See
`docs/INTEGRATIONS.md` for the honest state of harness integrations.
