Snip

OpenCode plugin that automatically prefixes shell commands with snip to reduce LLM token consumption by 60-90%.

What is snip?

snip is a CLI proxy that filters shell output before it reaches your LLM context window.

Command	Before	After	Savings
go test ./...	689 tokens	16 tokens	97.7%
git log	371 tokens	53 tokens	85.7%
cargo test	591 tokens	5 tokens	99.2%

Installation

1. Install snip

brew install edouard-claude/tap/snip
# or
go install github.com/edouard-claude/snip/cmd/snip@latest

2. Configure OpenCode

Add the plugin to your OpenCode config (~/.config/opencode/opencode.json):

{
  "$schema": "https://opencode.ai/config.json",
  "plugins": ["opencode-snip@latest"]
}

The plugin targets OpenCode v2. On OpenCode v1, use opencode-snip@2.

How It Works

The plugin uses the tool execute.before hook to forward each shell command to snip hook, the same rewrite engine snip uses for Claude Code and other agents (tested with snip v0.25.2):

• only commands snip has a filter for are rewritten to snip run -- <command>, each segment of &&, ||, ; chains separately
• commands whose output feeds a pipe or a file redirection, heredocs, shell blocks and command substitutions are left untouched
• if snip hook fails, the command runs unchanged
