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 ChatGPT, Codex, Claude, 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
• Run native Promptfoo suites locally or in CI with telvine eval run
• Import metadata-only results with telvine eval import
• Review immutable suite revisions, repeated trials, calibration, and release checks
• Mark versions stable only after required evaluation policies pass

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