machine-os

23 engineering skills across 3 tiers (Engineering, Security & Operations, Intelligence) for AI IDEs. Includes code-review, architecture-review, security-review, threat-model, rag-review, document-extraction, hallucination-audit, task-decomposition, and more. Every skill follows a shared contract (machine_output + skill graph), works standalone, and gets supercharged when you connect your tools (see CONNECTORS.md and SKILL-CONTRACT.md).

Optional MCP tool backends for the ai-engineering skills, powered by Machine OS engines. Spokes: code-graph blast radius (agent-context) supercharges /code-review and /tech-debt; agent-memory (mcp-agent-toolkit) gives /debug and /incident-response SCAR failure memory and /agent-design a shared blackboard; agent-extractor (Python, via uvx) gives /document-extraction real PDF→JSON extraction with validation. Install only if you want the tools; the skills work standalone without them.
