About

harness-architect is a plugin bundle for AI coding tools published by leee880619-commits. Marketplaces we read that list it: 1 (Claude Code: claude-plugins-community). We first saw it on 2026-10-11 and have recorded no change since. As of our marketplace pass on 2026-10-14.

In its own words, on Claude Code: claude-plugins-community:

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 / NOTE classifications, and cross-phase state is persisted to `docs/{request}/` so interrupted sessions resume deterministically. Target users: anyone — including non-developers — who wants a correct-from-day-one Claude Code setup on every new project without re-deriving the same 30-decision matrix each time. The plugin ships a 6-step "strict-coding" preset for complex coding projects and three Phase 1-2 branches (fresh setup / Cursor migration / harness audit).

Is this your plugin?

Add it to your projects and prove you maintain it with a file in its repository, a file on your domain or a DNS record. You get alerts when a marketplace lists it, drops it, changes its verified mark or what it asks for, and its remote endpoint goes on monitoring as a web service.

Data comes from the public marketplace file https://github.com/anthropics/claude-plugins-community/blob/HEAD/.claude-plugin/marketplace.json. Figures come from our own regular passes over the marketplaces, last read on . We publish no contact details for plugin publishers.
