AI agent skills (Claude Code, Cursor, OpenCode) are markdown files that look portable but aren't. A skill depending on bash or web_search silently fails on other platforms. Skills Compat Manager = CLI + MCP server: discovers skills from 6+ platforms, scans 4 dependency dims (pip/CLI/env/caps), AI-generates COMPAT.yaml (OpenAI/Claude/rules fallback), cross-platform matrix showing exactly what breaks where, MCP mode auto-injects compat info into every skill fetch. MIT, Python 3.11+, free.
Most AI coding tools give you autocomplete. /dev gives you an engineering process. A 6-phase SOP turning Claude Code into a Tech Lead with parallel Worker Agents in isolated worktrees: PRD alignment, architecture, coding, QA, code review, and iteration. Includes conflict detection, counterexample checks, mandatory security audits, and DB migration guards. Open source, MIT.
