What is cx?

cx is a thin wrapper around Claude Code that applies modular, opt-in patches at runtime via AST transformation. The original claude binary is never modified — cx parses the bundle, applies your selected patches, caches the result, and spawns it. Everything else passes through untouched.

Why cx?

Claude Code is great. But some things can't be configured with settings alone:

• Message queue — Ctrl+Q lets you steer Claude mid-response. Buffer your next instruction while it's still working — it gets injected as a user turn immediately.
• Persistent max effort — Claude resets effort level every session. cx saves "max" to settings so you don't have to /model it back every time.
• See your pasted text — Voice dictation and large pastes get collapsed into [Pasted text #N] which hides what you actually said. cx shows it inline so you can verify what was sent.
• No attribution — No more Co-authored-by: Claude in your commits and PRs.
• Swap Enter / Option+Enter — Enter inserts a newline, Option+Enter submits. Essential if you're on SSH, a non-English keyboard, or just prefer multiline-first input.
• Context usage, always visible — See how much context you've used at all times, not just when you're about to hit the wall.
• Hot reload — Change patches, tweak config, update Claude Code — press Ctrl+X Ctrl+R and the session restarts with fresh patches. Your conversation continues via --continue.
• Quiet mode — No spinner tips, no feedback surveys, no npm-to-native-installer nag.
