Claude Code

systemg ships an official Claude Code plugin and skill so coding agents can drive sysg correctly — writing valid manifests, starting and inspecting stacks, and reading logs — without you pasting docs into every session. The plugin is distributed from a self-hosted marketplace in the systemg repository, so you install it straight from GitHub.

​
What you get

  • A plugin (systemg) that registers the systemg skill with Claude Code.
  • A skill that teaches Claude the sysg CLI, the YAML config schema, deployments, cron units, and log inspection — including the agent-friendly --plain conventions.

​
Install

Add the marketplace, then install the plugin: 
/plugin marketplace add ra0x3/systemg
/plugin install systemg
/plugin marketplace add ra0x3/systemg points Claude Code at the .claude-plugin/marketplace.json at the repository root; /plugin install systemg installs the plugin from it. You can also browse and install interactively from the /plugin menu once the marketplace is added.

​
Updating

The plugin version is kept in lockstep with the systemg release. CI stamps .claude-plugin/plugin.json with the crate version from Cargo.toml on every release, so the marketplace always advertises the current version. Refresh the marketplace to pick up new releases: 
/plugin marketplace update systemg
Claude Code surfaces available updates for installed plugins, so in practice you are prompted to update rather than having to check by hand.

​
Using the skill

Once installed, the skill activates automatically whenever you ask Claude to work with systemg — for example:
  • “Write a sysg.yaml for a Postgres + API stack with a health check.”
  • “Start this stack and show me the status as JSON.”
  • “Tail the api service logs and grep for errors in the last hour.”
Under the hood the skill instructs Claude to use --plain in non-interactive contexts, to prefer --format json for parsing, and to run sysg validate before starting a stack so config mistakes are caught early with precise, fixable diagnostics.
