Agent Arche

Agent Arche is an agentic orchestration framework for GitHub Copilot that installs a full multi-agent system into any project's .github/ folder via a single npx command. It includes ten specialist agents (Orchestrator, Planner, Researcher, Coder, Designer, Code Reviewer, Security Auditor, UX Reviewer, Tester, Docs Updater), each with a defined role and strict scope. The Orchestrator classifies requests, builds a phased pipeline, confirms with the user, then delegates, never writing code itself. Over twenty skills cover planning workflows (grill-me, to-prd, to-issues, TDD), design aesthetics (design, soft, minimalist, brutalist, redesign, animate, GSAP), code quality (coding-standards, api-design, architecture, ui-audit, SEO), and git conventions (commit-conventions, branch-conventions, pr-standards). Hooks enforce safety automatically: session-start injects universal rules, pre-tool-safety warns before destructive shell commands and scans for hardcoded secrets, changelog-reminder prompts after every source file edit. Auto-injected instructions activate by file type, covering TypeScript strict mode, Svelte 5 runes syntax, test structure, and API route input validation. A persistent memory vault at .github/memory/ is Obsidian-compatible with color-coded note types (decisions, patterns, learnings, sessions, reviews) linked via wiki-links, seeded by the analyze-codebase skill on first run.
