Claude Code plugin & skills

If you live in Claude Code, this is the fastest way to use Jetty. The plugin bundles four skills and the MCP server together, so a single install gives you natural-language commands, a guided setup wizard, and the runbook-authoring loop without leaving your editor.

Install

Two commands add the marketplace and install the plugin:

claude plugin marketplace add jettyio/jettyio-skills
claude plugin install jetty@jetty

Then run the setup wizard once. It creates or links your account, writes your token to ~/.config/jetty/token, and checks that your model provider keys are in place:

/jetty-setup

That's it. The token it writes is the same one every other on-ramp reads, so the MCP server, the SDK, and the CLI are all configured at the same time.

The four skills

jetty: natural-language workflow control

Talk to Jetty in plain English. The skill maps your request onto the underlying API, so you don't have to remember endpoints or JSON shapes.

/jetty list collections
/jetty list tasks in acme
/jetty run triage in acme with ticket="customer can't log in"
/jetty show the last trajectory for triage

jetty-setup: first-run onboarding

The wizard you run once. Handles account creation, token storage, and a provider-key pre-flight so your first runbook doesn't fail on a missing key.

create-runbook: author a new runbook

Guided authoring for a brand-new runbook: it asks what you want done, what “done” looks like, and what to check, then writes a structured RUNBOOK.md with frontmatter and evals. See Writing runbooks for the anatomy.

optimize-runbook: hill-climb an existing one

The retention loop. It reads your prior trajectories, finds where runs fall short of the runbook's evals, proposes targeted edits, and re-runs to confirm the score moved. Walkthrough in Evaluating & optimizing.

What's under the hood

The plugin ships the same MCP server the rest of the editors use, so when you run /jetty run …, Claude Code is calling the run-workflow MCP tool against flows-api.jetty.io. The skills are the Claude-Code-specific layer on top; the MCP tools work in every editor.

No install? Use the shell CLI

The same repo ships a dependency-free shell CLI. Source it and you get a set of jetty_* functions for quick checks and scripts:

source jetty-cli.sh   # from the jettyio-skills repo
jetty_collections
jetty_run_sync acme triage '{"ticket":"can'\''t log in"}'

Source: jettyio/jettyio-skills. Next: add the MCP server to another editor →
