what is crux?
.crux/ is a directory that stores everything your AI learns —
corrections, patterns, session state, safety rules.
it travels with you. no matter what tool you use.
$ crux switch opencodestart in Claude Code at work. pick up in OpenCode at home. same knowledge. same corrections. same context.
features
- tool-agnostic intelligence — works with every AI coding tool, switch freely
- 7-gate safety pipeline — preflight, TDD, security audit, adversarial LLM review, human approval
- 24 specialized modes — build-py, debug, security, design-ui, psych, legal, and more
- seamless tool switching — your context travels with you between tools
- 66-tool MCP server — single 6.6MB Rust binary, zero dependencies, every tool connects
- mid-session onboarding — start using crux on existing projects without losing context
- session recovery — recover context from corrupted Claude Code sessions
- compare with competitors — see how Crux works alongside Cursor, Claude Code, Aider, and more
latest from the build log
- crux 0.1: 66-tool rust binary with autonomous evolution
- Test plan - verify BIP end-to-end flow triggers blog generation and site deploy
- Wire BIP end-to-end: plan_implemented event → escalation check → coordinated_publish (blog + X + deploy). Currently detection and publishing exist but are not connected.
