* fix(daemon): keep the runtime brief byte-stable across triggers (MUL-5377) Claude Code loads the runtime brief (CLAUDE.md / AGENTS.md) into messages[0], ahead of the entire conversation. A cache breakpoint is all-or-nothing, so a single differing byte there invalidates the prompt cache for the whole history on every `--resume`. InjectRuntimeConfig rewrites that file on every run and interpolated nine per-run values into it, so in practice the cache was thrown away on the first comment that landed on any issue. Measured on one issue over three runs: run 1 (cold) spent 89.9k cache-write tokens building 105k of context; runs 2 and 3 each spent ~425k re-creating a prefix they should have read. 842k of 946.5k cache-write tokens (89%) went into re-creation, with only tools[]+system[] surviving each resume (a constant 18,085 tokens both times). Fix: the brief now carries only what is stable for the lifetime of a resumed session, and per-run state travels in the per-turn user message, which is appended after the cached prefix. - Merge kindCommentTriggered + kindAssignmentTriggered into kindIssue, and stop reading TriggerCommentID in classifyTask. The brief can no longer diverge by trigger type structurally, rather than by convention. - Replace writeWorkflowComment/writeWorkflowAssignment with one writeWorkflowIssue that routes on the per-turn message. The mode-specific status rules live inside their own mode block, so "own the status arc" and "do not touch the status" can never be read as unarbitrated peers. - Move Task Initiator, Session Continuity Notice and Connected Apps out of the brief into BuildPrompt via BuildTaskInitiatorBlock / SessionContinuityNotice / BuildConnectedAppsBlock. - Drop TriggerCommentID, TriggerThreadID, NewCommentsSince, NewCommentCount, PriorSessionResumed and CommentReplyTargets from the brief; BuildPrompt already emitted all six from the same helpers, so this is de-duplication. - Set PriorSessionResumeUnavailable on `task` as well as `taskCtx` in both local resume gates, or the notice would silently vanish on exactly the failure path it exists to disclose. Tests: TestInjectRuntimeConfigByteIdenticalAcrossTriggers renders the brief across nine per-run variants (trigger type, differing comment/thread ids, resume delta, resume-unavailable, cross-thread fan-out, member/agent initiator, connected apps) for two providers and requires bytes.Equal, with a non-vacuity guard so it cannot pass on a function that ignores its input. Daemon-side tests assert the moved sections still reach the agent through the per-turn prompt. Co-authored-by: multica-agent <github@multica.ai> * fix(daemon): route the issue workflow on an explicit turn-mode marker Review follow-up on the mode router. The brief said Reply mode applies when the per-turn message "opens with a [NEW COMMENT] block", but buildCommentPrompt writes two paragraphs before that block and only emits it when TriggerCommentContent is non-empty. Two ways to get it wrong: - The message never literally opens with the block, so the router's own wording did not match the prompt it describes. - A comment-triggered run with an empty comment body — or an older server that does not send one — emitted no block at all. An agent following the brief would fall through to Ownership mode and change the issue status on a turn whose rule is "do NOT change the issue status". BuildPrompt now emits an unconditional `**Turn mode: Reply.**` / `**Turn mode: Ownership.**` line from the same branches it uses to pick a code path, and the brief routes on that marker. Brief and prompt can no longer disagree about the mode, because the value that selects the path also states it. The router also names a safe fallback (treat an unlabelled turn as Reply mode and leave the status alone). Tests: TestTurnModeMarkerAlwaysPresent covers comment-triggered with and without comment content, plus both assignment shapes; TestTurnModeMarkerAbsentOnIssuelessKinds keeps the marker off chat / quick-create / autopilot; TestBriefModeRouterMatchesPromptMarkers fails if the brief ever describes a marker the prompt does not emit.

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, CodeBuddy, GitHub Copilot CLI, OpenCode, OpenClaw, Hermes, Pi, Cursor Agent, Kimi, Kiro CLI, Antigravity, Qoder CLI, and Trae CLI.
For larger teams, Squads add a stable routing layer: assign work to a group led by an agent, and the leader delegates to the right member.
Why "Multica"?
Multica — Multiplexed Information and Computing Agent.
The name is a nod to Multics, the pioneering operating system of the 1960s that introduced time-sharing — letting multiple users share a single machine as if each had it to themselves. Unix was born as a deliberate simplification of Multics: one user, one task, one elegant philosophy.
We think the same inflection is happening again. For decades, software teams have been single-threaded — one engineer, one task, one context switch at a time. AI agents change that equation. Multica brings time-sharing back, but for an era where the "users" multiplexing the system are both humans and autonomous agents.
In Multica, agents are first-class teammates. They get assigned issues, report progress, raise blockers, and ship code — just like their human colleagues. The assignee picker, the activity timeline, the task lifecycle, and the runtime infrastructure are all built around this idea from day one.
Like Multics before it, the bet is on multiplexing: a small team shouldn't feel small. With the right system, two engineers and a fleet of agents can move like twenty.
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.
- Squads — group agents (and humans) under a leader agent and assign work to the squad. The leader decides who should pick it up, so routing stays stable as the team grows.
@FrontendTeaminstead of@alice-or-bob-or-carol. - Autonomous Execution — set it and forget it. Full task lifecycle management (enqueue, claim, start, complete/fail) with real-time progress streaming via WebSocket.
- Autopilots — schedule recurring work for agents. Cron triggers, webhooks, or manual runs — each autopilot creates the issue and routes it to an agent automatically, so daily standups, weekly reports, and periodic audits run themselves.
- 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
macOS / Linux
Homebrew (recommended)
brew install multica-ai/tap/multica
Use brew upgrade multica-ai/tap/multica to keep the CLI current.
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.
Then configure, authenticate, and start the daemon in one command:
multica setup # Connect to Multica Cloud, log in, start daemon

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, codebuddy, copilot, opencode, openclaw, hermes, pi, cursor-agent, kimi, kiro-cli, agy, qodercli, traecli) 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, CodeBuddy, GitHub Copilot CLI, OpenCode, OpenClaw, Hermes, Pi, Cursor Agent, Kimi, Kiro CLI, Antigravity, Qoder CLI, or Trae CLI). 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.
