Harness Architect

plugin

harness-architect is a meta-tool that scans any target project and builds an end-to-end Claude Code harness — CLAUDE.md, settings, rules, agents, playbooks, hooks, and MCP — through a 9-phase orchestrated workflow. The plugin enforces a strict Agent-Playbook separation (WHO / HOW): agents define identity and hand off methodology to sub-agent-only playbooks, preventing the main session from bypassing guardrails. Every phase is reviewed by an independent red-team advisor that produces BLOCK / ASK

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

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.
