Bohan Jiang f1082b10a4 feat(cli): add --assignee-id / --to-id / --user-id for unambiguous targeting (#2114)
* feat(cli): add --assignee-id / --to-id / --user-id for unambiguous targeting

`multica issue {create,update,list}`, `issue assign`, and `issue subscriber
{add,remove}` accepted only fuzzy name matching, which fails in workspaces
where one user's name is a substring of another (e.g. agent "J" vs
"Cursor - J" / member "Jiayuan"). #1642 added UUID acceptance through the
existing flags, but there was still no explicit path that signals "this is a
UUID, not a name" — important for scripts that read IDs from
`multica workspace members --output json`.

Adds an `-id`-suffixed counterpart for every assignee-taking flag:

- `issue list`     : --assignee-id
- `issue create`   : --assignee-id
- `issue update`   : --assignee-id
- `issue assign`   : --to-id
- `issue subscriber {add,remove}` : --user-id

The new flags route through `resolveAssigneeByID`, a strict resolver that
requires a canonical UUID and fails with a clear error when the entity is
not in the workspace (no name fallback). A shared `pickAssigneeFromFlags`
helper enforces mutual exclusion between the name and id flags so a script
that accidentally sets both never silently applies one over the other.

Refs MUL-1254.

* fix(cli): detect assignee flag presence via Changed, not value-emptiness

`pickAssigneeFromFlags` previously branched on `flag value != ""`, so
explicitly passing an empty UUID silently routed through the "no flag set"
path:

  multica issue list --assignee-id ""        # listed every issue
  multica issue create --assignee-id ""      # created an unassigned issue
  multica issue subscriber add --user-id ""  # subscribed the caller

This is exactly the failure mode the strict-UUID flag was added to prevent —
a script interpolating `--assignee-id "$MAYBE_UUID"` against a missing env
var should fail loudly, not silently degrade to a different operation.

Switch the picker (and the assign-command top-level guard) to use
`Flags().Changed`, so an explicit empty value reaches `resolveAssigneeByID`
/ `resolveAssignee` and surfaces a clear "expected a canonical UUID" /
"no member or agent found matching" error.

* docs(cli): cover --assignee-id / --to-id in user docs and quick-create prompt

Follow-up to the --*-id flag rollout: surface the new flags everywhere the
old ones are documented so users (and agents) can discover them.

- assigning-issues.{mdx,zh.mdx}: the page explicitly calls out the
  duplicate-name footgun ("first one listed wins, so rename before
  assigning") — replace that workaround with a --to-id <uuid> example
- cloud-quickstart.{mdx,zh.mdx}: add a --to-id hint after the substring-
  match callout so first-time users learn about the strict path
- internal/daemon/prompt.go (quick-create injected prompt):
  - default-to-self: pass --assignee-id <task.Agent.ID> instead of
    --assignee <name>; the picker agent's UUID is already in scope and
    UUID matching is unambiguous in workspaces with overlapping agent
    names (J / Cursor - J / Pi - J etc.)
  - user-named: tell the agent to prefer --assignee-id <uuid> using the
    user_id/id from the JSON it already fetched; --assignee <name> stays
    a fallback for unambiguous workspaces

title: Cloud quickstart
description: From sign-up to assigning your first task to an agent in 5 minutes.

import { Callout } from "fumadocs-ui/components/callout";
This page walks you end-to-end through Multica Cloud — **sign up → install the [CLI](/cli) → start the [daemon](/daemon-runtimes) → create an [agent](/agents) → assign your first [task](/tasks)**. Takes about 5 minutes.
One prerequisite: you already have at least one [AI coding tool](/providers) installed locally ([Claude Code](/providers#claude-code), [Codex](/providers#codex), [Cursor](/providers#cursor), [Copilot](/providers#copilot), [Gemini](/providers#gemini), [Hermes](/providers#hermes), [Kimi](/providers#kimi), [Kiro CLI](/providers#kiro-cli), [OpenCode](/providers#opencode), [OpenClaw](/providers#openclaw), or [Pi](/providers#pi)). The daemon auto-detects them on startup and refuses to start if none are present.
## 1. Create an account
Sign up at [multica.ai](https://multica.ai). You can log in with email (6-digit verification code) or Google.
After sign-up you're automatically placed in a default workspace (generated from your account name). You can rename it later, or create new workspaces.
## 2. Install the Multica CLI
**macOS / Linux (Homebrew recommended)**:
```bash
brew install multica-ai/tap/multica
```
**macOS / Linux (no Homebrew)**:
```bash
curl -fsSL https://raw.githubusercontent.com/multica-ai/multica/main/scripts/install.sh | bash
```
**Windows (PowerShell)**:
```powershell
irm https://raw.githubusercontent.com/multica-ai/multica/main/scripts/install.ps1 | iex
```
Verify the install:
```bash
multica version
```
## 3. Log in + start the daemon
A single command handles login and starts the daemon:
```bash
multica setup
```
`multica setup` will:
1. Configure the CLI to connect to Multica Cloud
2. Open your browser for login (same email verification code / Google OAuth as the web)
3. Store the generated PAT in `~/.multica/config.json`
4. **Start the daemon automatically** — it begins polling for tasks every 3 seconds and sending heartbeats every 15 seconds
<Callout type="info">
**Using the desktop app?** The desktop app **starts the daemon automatically** on launch — no need to run `multica setup` by hand. See [Desktop app](/desktop-app).
</Callout>
Verify the daemon is running:
```bash
multica daemon status
```
`online` means it has registered with the server.
## 4. Verify the runtime is online
In the web UI, go to **Settings → Runtimes**. The daemon you just started should appear as one or more active runtimes — one per AI coding tool installed locally.
If it shows as offline, don't panic — see [Troubleshooting → Daemon can't reach the server](/troubleshooting#daemon-cant-reach-the-server).
## 5. Create an agent
In the web UI, go to **Settings → Agents** and click **New Agent**:
- **Name** — the name shown for this agent on boards and in comments. Pick something you like
- **Provider** — choose an AI coding tool you have installed locally (the dropdown only lists tools detected by your runtimes)
- **Model** (optional) — the model selection inside that tool (a static list or dynamic discovery, depending on the provider)
- **Instructions** (optional) — system prompt for this agent
Once created, the agent shows up in your workspace member list and can be assigned work like a human member.
## 6. Assign your first task
Create an issue in the web UI, or from the CLI:
```bash
multica issue create --title "Add an ASCII architecture diagram to the README"
```
Assign the issue to the agent you just created — click its avatar in the web UI, or use the CLI:
```bash
multica issue assign MUL-1 --to my-agent-name
```
`--to` takes the **name** of an agent or member. A substring match works — if the agent is called `my-code-reviewer`, `reviewer` resolves to it. If your workspace has overlapping names, pass `--to-id <uuid>` instead (mutually exclusive with `--to`); look up the UUID via `multica agent list --output json` or `multica workspace members --output json`.
**What happens next from the daemon**:
1. It picks up the task within 3 seconds (status goes from `queued` to `dispatched`)
2. It invokes the matching AI coding tool to start work (status becomes `running`)
3. The AI works locally — it may read your code directory, run commands, edit files
4. When done, it reports the result back to Multica (status becomes `completed` or `failed`, depending on whether auto-retry kicks in)
The web UI updates in **real time** (via WebSocket) — no refresh needed.
## Next steps
- [Daemon and runtimes](/daemon-runtimes) — how the daemon operates and what runtimes mean
- [Tasks](/tasks) — task lifecycle and retry rules
- [AI coding tools compared](/providers) — capability differences across the 11 tools
- [Desktop app](/desktop-app) — if you'd rather not run the daemon yourself
- [Self-host quickstart](/self-host-quickstart) — run your own backend
