LinYushen b5de04da59 fix(daemon): platform-aware Codex sandbox config to unbreak macOS network (MUL-963) (#1246)
* fix(daemon): platform-aware Codex sandbox config to unbreak macOS network

On macOS, Codex's Seatbelt sandbox in workspace-write mode silently
ignores '[sandbox_workspace_write] network_access = true' (see
openai/codex#10390). That blocks DNS inside the sandbox, so 'multica
issue get' and other CLI calls fail with 'dial tcp: lookup ...: no such
host' — this is what caused MUL-963.

Changes:

- New server/internal/daemon/execenv/codex_sandbox.go: picks a sandbox
  policy based on runtime.GOOS and the detected Codex CLI version.
  Non-darwin or darwin with a known-fixed version keeps workspace-write
  + network_access=true; older darwin falls back to danger-full-access
  and logs a warn with upgrade hint. The fix-version threshold is a
  single constant (CodexDarwinNetworkAccessFixedVersion) so it's easy
  to bump once upstream ships.
- Per-task config.toml now gets a 'multica-managed' marker block
  (BEGIN/END comments) rewritten idempotently; user-owned keys outside
  the markers are preserved. Legacy inline sandbox directives from
  earlier daemon versions are stripped on migration.
- execenv.PrepareParams gains CodexVersion; execenv.Reuse takes a
  codexVersion arg; daemon.go caches detected versions at registration
  and threads them through to Prepare/Reuse.
- Replaces the old ensureCodexNetworkAccess tests with
  platform-parameterised coverage (linux vs darwin, idempotency,
  legacy-migration, policy matrix).
- docs/codex-sandbox-troubleshooting.md: symptom fingerprint table,
  decision matrix, self-check commands, trade-offs.

* fix(daemon): hoist managed sandbox block above user tables (MUL-963)

Review on #1246 flagged that upsertMulticaManagedBlock appended the
managed block to EOF. If the user's config.toml ends inside a TOML table
(e.g. [permissions.multica] or [profiles.foo]), a trailing bare
sandbox_mode = "..." is parsed as a key of that preceding table, so
Codex silently ignores the policy the daemon meant to apply.

Two changes make the block position-independent:

- renderMulticaManagedBlock now emits only top-level key=value lines and
  uses TOML dotted-key form (sandbox_workspace_write.network_access =
  true) instead of opening a [sandbox_workspace_write] header. The block
  therefore neither inherits from nor leaks into any surrounding table.
- upsertMulticaManagedBlock always hoists the block to the top of the
  file (stripping any previously written managed block first), so the
  sandbox_mode line is always at the TOML root regardless of what the
  user put below it. This also migrates configs written by the original
  PR #1246 logic where the block was trapped behind a user table.

Added tests for the regression scenario (pre-existing [permissions.*]
table) and the legacy-trailing-block migration; updated the existing
Linux default test and the troubleshooting runbook to reflect the
dotted-key form.

What is Multica?

Multica turns coding agents into real teammates. Assign issues to an agent like you'd assign to a colleague — they'll pick up the work, write code, report blockers, and update statuses autonomously.

No more copy-pasting prompts. No more babysitting runs. Your agents show up on the board, participate in conversations, and compound reusable skills over time. Think of it as open-source infrastructure for managed agents — vendor-neutral, self-hosted, and designed for human + AI teams. Works with Claude Code, Codex, OpenClaw, OpenCode, Hermes, Gemini, Pi, and Cursor Agent.

Features

Multica manages the full agent lifecycle: from task assignment to execution monitoring to skill reuse.

  • Agents as Teammates — assign to an agent like you'd assign to a colleague. They have profiles, show up on the board, post comments, create issues, and report blockers proactively.
  • Autonomous Execution — set it and forget it. Full task lifecycle management (enqueue, claim, start, complete/fail) with real-time progress streaming via WebSocket.
  • Reusable Skills — every solution becomes a reusable skill for the whole team. Deployments, migrations, code reviews — skills compound your team's capabilities over time.
  • Unified Runtimes — one dashboard for all your compute. Local daemons and cloud runtimes, auto-detection of available CLIs, real-time monitoring.
  • Multi-Workspace — organize work across teams with workspace-level isolation. Each workspace has its own agents, issues, and settings.

Quick Install

brew install multica-ai/tap/multica

Use brew upgrade multica-ai/tap/multica to keep the CLI current.

macOS / Linux (install script)

curl -fsSL https://raw.githubusercontent.com/multica-ai/multica/main/scripts/install.sh | bash

Use this if Homebrew is not available. The script installs the Multica CLI on macOS and Linux by using Homebrew when it is on PATH, otherwise it downloads the binary directly.

Windows (PowerShell)

irm https://raw.githubusercontent.com/multica-ai/multica/main/scripts/install.ps1 | iex

Then configure, authenticate, and start the daemon in one command:

multica setup          # Connect to Multica Cloud, log in, start daemon

Self-hosting? Add --with-server to deploy a full Multica server on your machine:

curl -fsSL https://raw.githubusercontent.com/multica-ai/multica/main/scripts/install.sh | bash -s -- --with-server
multica setup self-host

Requires Docker. See the Self-Hosting Guide for details.


Getting Started

1. Set up and start the daemon

multica setup           # Configure, authenticate, and start the daemon

The daemon runs in the background and auto-detects agent CLIs (claude, codex, openclaw, opencode, hermes, gemini, pi, cursor-agent) on your PATH.

2. Verify your runtime

Open your workspace in the Multica web app. Navigate to Settings → Runtimes — you should see your machine listed as an active Runtime.

What is a Runtime? A Runtime is a compute environment that can execute agent tasks. It can be your local machine (via the daemon) or a cloud instance. Each runtime reports which agent CLIs are available, so Multica knows where to route work.

3. Create an agent

Go to Settings → Agents and click New Agent. Pick the runtime you just connected and choose a provider (Claude Code, Codex, OpenClaw, OpenCode, Hermes, Gemini, Pi, or Cursor Agent). Give your agent a name — this is how it will appear on the board, in comments, and in assignments.

4. Assign your first task

Create an issue from the board (or via multica issue create), then assign it to your new agent. The agent will automatically pick up the task, execute it on your runtime, and report progress — just like a human teammate.


Multica vs Paperclip

Multica Paperclip
Focus Team AI agent collaboration platform Solo AI agent company simulator
User model Multi-user teams with roles & permissions Single board operator
Agent interaction Issues + Chat conversations Issues + Heartbeat
Deployment Cloud-first Local-first
Management depth Lightweight (Issues / Projects / Labels) Heavy governance (Org chart / Approvals / Budgets)
Extensibility Skills system Skills + Plugin system

TL;DR — Multica is built for teams that want to collaborate with AI agents on real projects together.


CLI

The multica CLI connects your local machine to Multica — authenticate, manage workspaces, and run the agent daemon.

Command Description
multica login Authenticate (opens browser)
multica daemon start Start the local agent runtime

Development

For contributors working on the Multica codebase, see the Contributing Guide.

Prerequisites: Node.js v20+, pnpm v10.28+, Go v1.26+, Docker

make dev

make dev auto-detects your environment (main checkout or worktree), creates the env file, installs dependencies, sets up the database, runs migrations, and starts all services.

See CONTRIBUTING.md for the full development workflow, worktree support, testing, and troubleshooting.
