SuperCtx is a Claude Code marketplace plugin that centralizes project context in .ctx/SUPERCTX.md so developers can keep multiple AI coding tools aligned through generated instruction shims.
About
SuperCtx is a Claude Code marketplace plugin that centralizes project instructions in .ctx/SUPERCTX.md and keeps tool-specific files as generated shims. Developers reach for it when one repository uses Claude Code, Codex, Gemini, or other assistants and CLAUDE.md-style files start drifting apart. Install from the marketplace and run the plugin to back up originals and regenerate aligned instruction files.
- Single .ctx/SUPERCTX.md hub backs up originals and emits tool-specific shims
- Supports Claude Code, Codex, Gemini, Copilot, Cursor, and Antigravity paths
- Install via marketplace add and plugin install superctx@superctx
- Prevents instruction-file drift when one repo uses multiple AI assistants

How do you stop CLAUDE.md, AGENTS.md, and GEMINI.md from drifting when one repository uses several AI coding assistants?
Unify CLAUDE.md, AGENTS.md, and GEMINI.md into one .ctx/SUPERCTX.md hub with generated shims so every AI coding tool shares the same project context.
Who is it for?
Teams using multiple AI coding tools on the same repo who want one local source of truth for project instructions.
Skip if: Repositories that standardize on a single assistant with one instruction file and no cross-tool sync needs.
What you get
A shared SUPERCTX.md hub, backed-up originals under .ctx/sources/, and generated shims at each tool's expected instruction paths.
Plugins in this marketplace
