Multi-Agent Relay Control is a plugin for Claude Code or Google Antigravity that runs a complete team of AI engineering agents in your terminal.
You can install the cross-repo team of agents as a user-level plugin. Once installed, running /marc:tech-lead brings in the coordinator, who automatically dispatches specialized agents like @dev, @sre, @design, and @sec to handle coding, infrastructure setups, and pre-merge audits.
who's in the channel
-
@techleadchannel op
Leader & router.
Reads the request, breaks it down, and convenes exactly the specialists the job needs. The only skill you invoke by hand:
/marc:tech-lead. - @devengineering Feature work, refactors, tests. Ships code across repos, including implementation, bug fixes, and the regression tests that keep them fixed.
- @srereliability Infra, deploys, observability. Owns runtime health, which includes pipelines, containers, logs/metrics, and self-healing diagnostics.
- @designfront-end UI, UX, and the screens. Builds the user-facing surfaces and flows, wired to real APIs, backed by the tests to guard them.
- @secsecurity Review & the merge gate. Audits changes before they land, serving as the pre-merge security pass that guards the tree.
what's on the server
-
one-command@techlead
Running
/marc:tech-leadhandles the entire lifecycle, including spec validation, project board updates, parallel task execution, and final tracking. - every-repouser-scope You install the team once as a user-scope plugin. The agents will follow you automatically into any workspace you open.
- the-boardboard sync Every task maps directly to an issue on your GitHub project board, tracking status categories like todo, in progress, blocked, and done.
-
zero-configruntime
No hardcoded configuration is required. The team finds your repo, organization, and project board at runtime using the
ghCLI. -
marc-initopt-in
Run
/marc:initto scaffold your local configuration. The command writes.agents/team.tomlon Google Antigravity, or.claude/team.tomlon Claude Code. It prints the planned content first so you can review it. - merge-gate@sec A read-only pre-merge diff review runs on every pull request, flagging high or critical security concerns before they land.
- lessonstwo-tier Self-improvement details accumulate in local memory buffers before flushing into versioned skills through a standard pull request.
- install-shauditable The install script runs completely locally. It outputs every command before running, uses no remote downloads, and relies on built-in plugin mechanisms.

/marc:tech-lead
git clone https://github.com/NexaDuo/mARC && cd mARC && ./install.sh
The shell path runs the repo's own install.sh. It echoes every command before running it, fetches no remote code, and uses only Claude Code's built-in plugin mechanism. Read it before you run it.

agy /marc:tech-lead
This registers the mARC plugin on the Google Antigravity harness. The agent team runs locally in your environment, utilizing the configured workspace directory.
