Ultraswarm
Let Claude orchestrate multiple external coding CLIs in isolated git worktrees with workflows, tiered QA, and Claude-only merge while workers write the code.
Overview
ultraswarm is a plugin marketplace for the Build phase that orchestrates external AI coding CLIs in git worktrees while Claude authors workflows, QAs, and merges.
What is this marketplace?
- Single-plugin marketplace (ultraswarm v0.4.0) for Claude-orchestrated multi-CLI swarms
- Workers: external AI coding CLIs (codex, gemini, grok, agy, droid, opencode) in isolated git worktrees
- Claude decomposes work, authors a Workflow, runs tiered QA, and performs merge—workers implement code
- Isolated worktrees reduce cross-agent filesystem conflicts on one repo
- Explicit split: CLIs write code; Claude owns orchestration, QA, and merge
- Marketplace bundles 1 plugin (ultraswarm v0.4.0)
- Named worker CLIs include codex, gemini, grok, agy, droid, opencode
- Orchestration model: Claude decomposes, QAs, merges; CLIs write code
Community signal: 3 GitHub stars.
What problem does it solve?
One Claude session cannot cheaply parallelize large implementation work across multiple coding agents without branch chaos and unclear ownership of merge.
Who is it for?
Experienced solo builders who already use multiple AI coding CLIs and want Claude-managed worktrees plus a defined QA and merge path.
Skip if: Beginners on a single small feature, or anyone unwilling to manage git worktrees and several external CLI installs.
What do I get? / Deliverables
After installing ultraswarm, Claude delegates coding to isolated CLI workers under a written Workflow, runs tiered QA, and merges from a single orchestrator.
- Installed ultraswarm plugin (v0.4.0)
- Claude-authored Workflow driving CLI workers in isolated worktrees
- Tiered QA pass and Claude-controlled merge into the target branch

Journey fit
Ultraswarm sits in Build as agent orchestration infrastructure, though decomposition and QA also touch Ship review habits. Agent-tooling captures CLI worker orchestration, worktree isolation, and workflow authoring—not shipping checkout or SEO.
How it compares
Multi-CLI orchestration plugin marketplace, not a single-model skill or a hosted CI-only test runner.
Common Questions / FAQ
Who is Ultraswarm for?
Ultraswarm is for advanced builders who want Claude to coordinate several external coding CLIs as parallel workers while retaining Claude-only merge control.
When should I use Ultraswarm?
Use Ultraswarm during Build when a task is large enough to split across codex, gemini, grok, or similar CLIs and you need isolated worktrees plus tiered QA before merge.
How do I add Ultraswarm to my agent?
Add the fubak/Ultraswarm marketplace to Claude Code, install the Ultraswarm plugin, ensure target external CLIs and git worktree tooling are available, then let Claude decompose work and author a Workflow for the swarm.
