* feat(agent): enable ACP thinking_level for the hermes provider (jcode) The reporter confirmed from jcode source (v0.71.1 and v0.73.0) that its advertised effort is genuinely applied, not just echoed: session/set_config_option waits for an `effort_changed` ack, and the provider request carries `reasoning.effort` upstream. That was the one open question blocking this half of GitHub #6720. The wrinkle is that `hermes` is one provider type over two unrelated binaries with opposite answers here: - jcode advertises option id `reasoning_effort` under category `thought_level` and applies it. The shared parser already matches on category, so the id being unrecognised costs nothing and the id we send back is jcode's own. - Hermes Agent has no effort surface on ACP at all. Re-verified against v0.20.0 today by driving `hermes acp` directly: session/new still returns only `_meta`, `models`, `modes`, `sessionId`, unchanged from the v0.18.2 finding in MUL-5770. A version gate cannot separate those — they are different projects, not different releases. The catalog can, and does: an empty catalog means no picker and no set_config_option call, so admitting `hermes` to acpCatalogThinkingProviders is safe for both. This is the case the catalog-driven design was built for. Also corrects the docs that stated hermes has no reasoning control. That is now binary-specific rather than universally true, and Copilot takes over as the example of a runtime with no effort dial at all. Co-authored-by: multica-agent <[email protected]> * test(handler): retarget the no-reasoning-control fixture from hermes to copilot These tests used hermes as the canonical runtime with no effort dial, so enabling it broke them in CI — they passed locally only because the handler suite skips without a database. Copilot takes over the role: it discovers over ACP but executes through its own CLI, so there is genuinely no live ACP session to carry an effort. The behavior being pinned is unchanged — a capability gap must not be reported as an unrecognised token. Adds the inverse assertion in the same test: hermes now accepts a level at the provider gate, since jcode applies one. Whether a picker appears is settled per session by the discovered catalog, not here. Verified against a real Postgres this time rather than the skip path. Co-authored-by: multica-agent <[email protected]> * fix(agent): keep the capability 400 for hermes runtimes with no effort dial Opening the thinking_level gate for the hermes provider regressed the majority of that provider's users. Hermes Agent, not jcode, is what most people run there, and it advertises no effort option — so a CLI `--thinking-level high` went from an immediate, accurate 400 to a 201 followed by the daemon silently dropping the level at task time. The provider name cannot distinguish the two binaries, but the model catalog the daemon already reports can: a hermes runtime whose catalog advertises no thinking levels is a Hermes Agent install. Consult it in the create and update paths and restore the capability message for that case, leaving jcode unaffected. Fails open on purpose. A cold cache, an offline daemon, or a never-discovered runtime all skip the check, so a valid jcode agent is never blocked before its first discovery; the daemon's pre-execution guard remains the backstop. Verified against a real Postgres, including the fail-open paths. Co-authored-by: multica-agent <[email protected]> * fix(agent): refuse a thinking level on an undiscovered hermes runtime Review caught that the fail-open branch was not the transient cold start I assumed. The model catalog is written only by ReportModelListResult, i.e. only after a client explicitly asks for a model list, so a caller who works through the CLI and never opens a model picker stays undiscovered indefinitely. Reading "unknown" as "supported" therefore left the majority Hermes Agent case exactly where it started: `--thinking-level high` accepted and persisted, then silently dropped by the daemon at task time. Replace the boolean with three states — present / absent / unknown — and refuse on unknown, but only for providers whose name does not determine the binary. `hermes` is the sole member; reasonix names one binary that does support an effort, so an undiscovered reasonix runtime stays allowed rather than being blocked before its first discovery. Unknown gets its own message rather than reusing "does not support a per-agent reasoning effort". That sentence would be actively false for a jcode runtime, sending its owner to look for a limitation that isn't there; naming the missing evidence points at what actually resolves it. Also adds the execution-chain coverage the review asked for: jcode-shaped ACP stubs prove set_config_option(reasoning_effort) goes out before session/prompt on both session/new and session/resume, and a Hermes Agent-shaped payload produces no config call at all. That is the substitute evidence for having no real jcode to test against. Skill and source map updated so the documented guarantee matches the code rather than being stronger than it. Co-authored-by: multica-agent <[email protected]> * fix(agent): word the undiscovered-runtime 400 for create as well as update The message pointed at "the agent's model picker", which does not exist on the create path — the agent is not created yet. "the model picker for this runtime" is accurate on both paths (review nit, PR #6814).

Multica
Agents that show up on the board.
Multica is an open-source workspace where you assign work to AI coding agents the way you'd assign it to a teammate — they pick up the issue, report progress, raise blockers, and hand it back for review. Self-hostable, works with 20 agent CLIs, no lock-in.
Website · Docs · Quickstart · Download · Vision · Self-Hosting · Discord · X
English | 简体中文
Your next 10 hires won't be human.
What is Multica?
You already run Claude Code, Codex, and three other agents. Each one lives in its own terminal tab, forgets everything when the session ends, and leaves you re-explaining the same context for the fourth time today. The more agents you add, the more of your day goes to babysitting them.
Multica puts those agents and your teammates in one workspace. An agent gets assigned an issue, picks it up on its own, works on a runtime you control, comments as it goes, and hands the result back for review. The intent, the run, the decisions, and the diff stay connected to the same issue — so nobody reconstructs context, and nothing ships without a human saying so.
Build the team.
Claude Code, Codex, Cursor, Kimi — you don't pick one. You hire them all.
- 20 agent CLIs → Claude Code, Codex, Cursor, Copilot, Kimi, OpenCode, and more.
- Agents as teammates → Give each one a name, a provider, and a runtime — they show up on the board like anyone else.
- Squads → Put agents and people on one team; the leader routes the work.
- Skills → Turn a solved problem into a playbook every agent reuses.
- Your own runtime → Their desk is your machine — a daemon on your laptop or cloud box. Code never leaves it.
Hand off the work.
It starts as three rough sentences in an issue. It ends as a pull request.
- Assign an issue → Pick an agent as assignee the way you'd pick a colleague — it takes the work from there.
- Autopilots → Run standups, audits, and reports on a cron — nobody to remind.
- Chat → Ask your workspace a question, or start work without filing anything.
- Projects → Group work and attach the repos and docs agents need as context.
Stay in the loop.
Which agent touched this? What did it run? What did it cost? Open the run.
- Execution log → Replay every tool call, command, and error, timestamped.
- Token usage → See what each run cost, per agent and per issue.
- Review gates → Work lands in review, not in main. You decide what ships.
- Inbox → Get pinged when an agent needs a call, not for every step.
- Retries and timeouts → Failed runs retry on their own, or stop and tell you why.
Make it yours.
Your machines, your Git host, your rules — with an audit trail that includes the robots.
- Self-host everything → Docker Compose or Helm, on your own infrastructure.
- Any Git host → GitHub, GitLab, Gitea, or Forgejo — self-hosted included.
- Workspaces → Separate agents, issues, and settings per team.
- Roles and access scopes →
owner,admin, andmember— and exactly which agents each member can run. - Security model → What an agent can reach, and what it can't.
- Slack, Lark, DingTalk, and WeCom → Trigger and follow agent work where your team already talks. DingTalk and WeCom are community-maintained.
- Web, desktop, and mobile → The same workspace on macOS, Windows, Linux, and iPhone — iOS builds from source today, not yet on the App Store.
- CLI and API → Every surface is scriptable. Agents drive Multica through the same CLI you do.
Get started
No terminal required: sign up at multica.ai, or download Multica Desktop for macOS, Windows, and Linux — it connects the computer it runs on as a runtime automatically.
The one prerequisite: the machine that will run agents needs at least one supported agent CLI installed and signed in — Claude Code, Codex, Cursor, and friends. Multica drives them; it doesn't ship them.
Self-hosting the whole thing
curl -fsSL https://raw.githubusercontent.com/multica-ai/multica/main/scripts/install.sh | bash -s -- --with-server
multica setup self-host
On Windows, set $env:MULTICA_MODE="with-server", then run the PowerShell installer:
irm https://raw.githubusercontent.com/multica-ai/multica/main/scripts/install.ps1 | iex.
This pulls the official images from GHCR and requires Docker. See the
Self-Hosting Guide; if the selected GHCR tag has not been published yet,
fall back to make selfhost-build from a checkout.
Your first agent in five minutes
1. Sign in. multica.ai in the browser, or open Multica Desktop.
2. Connect a computer. A runtime is any machine agents can work on — your laptop, or a cloud box. Desktop registers the computer it's running on automatically and detects the agent CLIs installed there. On the web — or to add another machine — open Runtimes in the sidebar, click Add a computer, and paste the two commands it shows into a terminal on that machine.
3. Create an agent. Open Agents in the sidebar and click New agent. Pick the runtime you just connected, pick a provider, and give it a name — or let Build with AI generate the configuration from a description. That name is how it shows up on the board and in comments.
4. Assign it something. File an issue and set the agent as assignee. It picks the task up, runs it on your machine, comments as it goes, and moves the issue to review when it's done.

Runtimes
Multica does not ship a model. It drives the agent CLIs you already have installed and authenticated, so switching providers is a dropdown, not a migration.

Development
Contributors: start with 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 every service.
See CONTRIBUTING.md for the full workflow, worktree support, testing, and
troubleshooting. The iOS client lives in apps/mobile/ — its
README covers building it onto your own iPhone.
We release most weekdays, so main moves quickly — pull often.
Why "Multica"?
Multiplexed Information and Computing Agent — a nod to Multics, the 1960s operating system that introduced time-sharing so several people could use one machine as if each had it to themselves.
Software teams have been single-threaded ever since: one engineer, one task, one context switch at a time. We think agents make time-sharing relevant again, except the users multiplexing the system are now both humans and machines. A small team shouldn't feel small.
The longer argument, and where we think this goes: VISION.md.
