symphony

Symphony marketplace

A Claude Code plugin marketplace that distributes Symphony — autonomous Linear → GitHub bug fixing, built on Claude Code's Workflow (multi-agent orchestration) engine.

Install

# 1. Add this marketplace (owner/repo — owner is the GitHub user or org that hosts it)
/plugin marketplace add gmilano/symphony-marketplace

# 2. Install the plugin
/plugin install symphony@symphony-marketplace

You can also add it from a git URL or a local checkout:

/plugin marketplace add https://github.com/gmilano/symphony-marketplace.git
/plugin marketplace add ./symphony-marketplace        # local path

Replace gmilano with your own GitHub user/org if you fork or re-host this repo.

marketplace add and install are two separate steps. Adding the marketplace only makes the plugin available; you still have to run /plugin install symphony@symphony-marketplace. If you installed it in the current session, run /reload-plugins to register it without restarting.

Once installed, run it with /symphony:symphony from inside the repository whose Linear bugs you want to fix. (Plugin skills are namespaced /<plugin>:<skill>, so the command is /symphony:symphony, not /symphony — you can also just say "run symphony".) See the plugin's own docs for full configuration: plugins/symphony/skills/symphony/README.md.

Requirements

• Linear (work queue) via the Linear MCP server — the launcher runs OAuth if needed.
• GitHub + the gh CLI, authenticated with push + PR rights on the target repo(s).
• A test suite the agent can run (auto-detected, or pin a command via the tests arg).

Updating

/plugin marketplace update symphony-marketplace

Bump the version in both marketplace.json and plugins/symphony/.claude-plugin/plugin.json when you publish changes.
