Built for the
AI-native engineer

Every tool we ship targets a concrete inefficiency in how AI agents consume compute. No dashboards, no configuration, no fluff.


PRECC Live

An under-3ms pre-execution hook that intercepts every bash command Claude issues, rewrites it through a staged skill pipeline, and returns the optimised version — saving up to 66% on API costs with zero workflow changes.

Note: Real savings will depend heavily on how you use Claude Code and what kind of commands you're running.

🧠

Skill Portfolio Engine

Applies ALL compatible skills per command. Context fix + warning ranking + RTK compression compound on every call.

🔀

jj Auto-Translation

Detects Jujutsu repos (.jj/) and auto-translates git commands. git add . saves ~40 tokens per call.

📦

RTK Compression

30+ rewrite rules reduce verbose commands to token-minimal equivalents. Community-driven.

🛡️

Fail-Open Guarantee

Hook error? PRECC exits 0 instantly. Claude Code is never blocked or delayed. Zero risk to your workflow.

🔧

Zero Config Install

One curl command installs and registers the hook. Works immediately with existing Claude Code sessions.
