Introduction

Telvine is the eval-and-improve control plane for agent plugins and Skills. Plugins are the installable apps distributed through agent harnesses such as Claude, Codex, and Copilot Cowork. A plugin may include one or more SKILL.md capabilities plus connectors, apps, hooks, agents, and runtime-specific components. Telvine records the plugin package inventory, accepts metadata-only production traces for components that a runtime, hook, wrapper, or integration can observe, and helps teams improve plugin and Skill versions with outcomes, feedback, evals, and release evidence.

What you can do in v0

• Install the CLI from npm: @telvine/cli@0.1.0, using npm i -g @telvine/cli@0.1.0
• Publish a plugin directory and record its component inventory, Skills, and evals
• Receive skill.invocation.{start,end,error}, skill.script.invoked, feedback.submitted, and skill.modified events
• Register plugin versions and their component inventory through /v1/plugins/:id/versions
• Receive plugin.install, plugin.update.applied, and plugin.component.{invoked,error} events when observable
• Forward events to any HTTPS endpoint via signed webhooks
• Export CSV / pull metrics via a REST API
• Keep PM-authored eval suites with plugin repos as versioned assets while wiring their results into the plugin and Skill improvement loop

Start with the quickstart, then use the production onboarding checklist when you are ready to put a plugin in front of real users.
