Summon other agents.

You have a favorite coding agent already. Jam Session lets it call Codex, Claude, Cursor, Grok, Copilot, Devin, and Muse, and have them plan, argue, review, and build together.

macOS · Linux · WSL — totally free, MIT licensed.

Getting started

Let your agent install Jam Session. Paste this prompt into your coding agent:

Install Jam Session by following https://jamsession.jamon.dev/install.md, then onboard.

Your agent installs it, reads the docs, and teaches you the ropes. That’s the whole onboarding.

Prefer to install it yourself?

curl -fsSL https://jamsession.jamon.dev/install.sh | sh

A coding agent using Jam Session skills to plan awards and medals with Claude, Codex, and Grok, then orchestrate implementation on another computer over SSH. — One jam: your agent conducts sessions across several providers — using Jam Session skills to plan, review, orchestrate, and work remotely.

No added dependencies.

No added packages

Jam Session is a few shell scripts, one standard-library Python terminal reader for Grok and Copilot usage, and Markdown skill files. It needs no database or added packages.

Use your favorite agent

This isn’t an app or a TUI. Your favorite coding agent uses the CLI to call and coordinate agents from other providers — you keep working the way you already do.

Skills in the box

These are the workflows you’ll ask for. Jam Session handles the supporting machinery.

Summon agent Starts or resumes a provider-native agent session. jamsession-summon-agent
Ping-pong planning Agents challenge and refine a plan in sequence. jamsession-ping-pong-planning
Contrarian review An adversarial reviewer tries hard to break the work. jamsession-contrarian-review
Agent panels Independent agents answer, then your agent synthesizes. jamsession-ask-agent-panel
Orchestrator Runs managers and workers for autonomous, parallel work. jamsession-orchestrate-agent-work
Agent usage Shows provider quotas, remaining capacity, and reset times. jamsession-get-agent-usage
Model recommendations Chooses Jamon’s preferred model for each kind of work. jamsession-model-recommendations

The orchestrator also has supporting skills for worksheets, worker discipline, and SSH. Your agent uses them when the work calls for them.

Easy to extend

If your favorite agent isn’t on the roster yet, a provider adapter is small enough that your agent can scaffold and fill one in. Paste this into your agent:

Use the jamsession CLI to add a new provider adapter. Ask me which provider CLI I want to add, and make sure it is already installed and authenticated. Run jamsession help make-adapter first, then create and test the adapter.

If your Jam Session provider adapter is working well for you, please have your agent open a pull request! I’d love to support more agent providers.
