ctx

ctx とは？

ctx gives AI coding agents project memory. Actx/ folder in your project root with plain markdown files that any agent reads on startup. It knows where the project stands, what patterns work, what mistakes to avoid, and what was in progress when the last session crashed. Loads ~80 lines instead of re-reading everything. Ships 12 dev workflow skills (TDD, debugging, code review, design intelligence). Works on Claude Code, Codex, Cursor, Windsurf, Gemini, Antigravity. Zero dependencies.
