Constellation Harness

Constellation Harness

A multi-agent software delivery workflow for [Claude Code](https://code.claude.com), packaged as plugins. An orchestrator classifies every request, routes it through specialist persona agents (architect → engineer → parallel reviewers → SDET/writer → devops), and enforces quality gates, workflow state, and review memory along the way.

Extracted from a markdown-based `.agentic` workflow system and reworked to use native Claude Code plugin primitives: subagents, skills, commands, and hooks.

Installation

The mental model: **install once per machine, then enable + init once per repo.** Installing a plugin only makes it *available* — i
