Harnesskit

plugin

Adaptive harness for vibe coders — automatically detects your repo stack, applies experience-level guardrails (beginner/intermediate/advanced), observes sessions via zero-token shell hooks, and continuously improves your workflow by proposing custom skills, agents, and hooks based on real usage data. Marketplace-first: uses existing plugins, customizes only when data shows a gap.

Works with: Claude Code (native)
native: this artifact type is that client's own format

Install (Claude Code):

/plugin marketplace add anthropics/claude-plugins-community
/plugin install harnesskit@claude-community

Security audit

Not scanned yet. We audit npm-published capabilities for known advisories, install-time scripts and permission surface; this one has no npm package we can resolve, or has not reached the queue.

You searched for one. Check the rest of your stack:

npx tashan-cli doctor

Reads the config already on your machine and names what is dead, deprecated or running code at install time. No account, nothing uploaded.

Everything on this page is public evidence and free. What it cannot know is whether you run this — check your whole config, free, in the browser. tashan Pro adds the series behind each row and names a replacement for anything dying.

Already running this? Check your whole config — free, in your browser, nothing installed. Or npx tashan-cli doctor locally, which sends nothing at all.
