Show HN: Agent Architect Skill for building agentic systems

A developer released Agent Architect, a skill for Claude Code and Codex that evaluates and designs multi-agent AI systems, offering AUDIT, REVIEW, and DESIGN modes. The tool scores systems across 11 dimensions including prompt architecture, tool design, context management, and production readiness, and installs into both ~/.claude/skills and ~/.agents/skills via a setup script.

Claude Code and Codex skills for evaluating and designing multi-agent systems. Senior architect review for agent systems, prompt engineering, and harness design. Three modes: AUDIT — Full 11-dimension evaluation of an existing agent system. Scores prompt architecture, tool design, context management, multi-agent orchestration, eval infrastructure, production readiness, model awareness, agent security, memory architecture, harness architecture, and multimodal architecture. Produces a maturity score with prioritized recommendations. REVIEW — Focused teardown of a specific prompt, skill file, or tool definition. Line-by-line findings with confidence scores. DESIGN — Architect a new agent system from scratch. Produces system prompt drafts, tool specs, failure mode maps, eval plans, and implementation checklists. The current agent-architect version is built for production AI systems, not just prompt review. It evaluates runtime API contracts, tool harness boundaries, MCP/tool governance, background task execution, trace-based evaluation, and voice/image/video surfaces when those modalities are present. ./setup installs each skill into both ~/.claude/skills and ~/.agents/skills . git clone git@github.com:YOUR ORG/agent-skills.git ~/.claude/skills/agent-skills cd ~/.claude/skills/agent-skills ./setup Or install from any location: git clone git@github.com:YOUR ORG/agent-skills.git ~/path/to/agent-skills cd ~/path/to/agent-skills ./setup In Claude Code: /agent-architect In Codex, once installed under ~/.agents/skills , reference agent-architect by name in your request. The skill auto-detects your codebase and selects the appropriate mode.
