snip

snip is a command-line proxy that sits between AI coding assistants and the shell, filtering verbose output through declarative YAML pipelines before it reaches the LLM's context window. It works with Claude Code, Cursor, Copilot, Gemini, and other AI coding tools that run shell commands.

The tool addresses token waste from verbose command output—like full test logs or git metadata—that adds little value to the LLM. Users define filters in simple YAML files without compiling code. A real Claude Code session showed 2.3M tokens saved across 128 commands with 99.8% average reduction per command. Installation is straightforward via Homebrew, curl, or Go.
