Skillbox
Keeps agent skills out of context until they're needed
Rust · Clap · Cargo 
Homebrew Coding agents drown in their own context. Skillbox keeps reusable skills in a registry outside the context window — agents search for what they need and fetch only that, instead of carrying every instruction everywhere.
One registry works across Claude Code, Codex, Pi, Cursor, and OpenCode. It’s a single Rust binary with tagged releases for macOS, Linux, and Windows: brew install hhushhas/tap/skillbox or cargo install.
