tags	rtk, token-saving, compression, cli, shell, devtools

Save 60-90% of LLM tokens on shell commands, file reads, and test outputs.

This skill wraps rtk (Rust Token Killer) — a CLI proxy that filters and compresses command outputs before they reach your LLM context.

Install

# 1. Install rtk
brew install rtk          # macOS
# or: curl -fsSL https://raw.githubusercontent.com/rtk-ai/rtk/refs/heads/master/install.sh | sh

# 2. Verify
rtk gain  # Should show token savings stats

Then copy this SKILL.md to your agent's skills directory.

Token Savings Analytics

rtk gain                               # Summary stats
rtk gain --graph                       # ASCII graph (last 30 days)
rtk gain --history                     # Recent command history
rtk gain --daily                       # Day-by-day breakdown
rtk gain --all --format json            # JSON export for dashboards
rtk discover                            # Find missed savings opportunities
rtk discover --all --since 7           # All projects, last 7 days

Rules for the Agent

Use rtk <command> instead of bare commands whenever possible:

Always use rtk for:

• rtk git status / rtk git log / rtk git diff
• rtk ls -la / rtk cat <file>
• rtk npm test / rtk pytest / rtk cargo test
• rtk npm run build / rtk ruff check

Don't use rtk for:

• Commands whose output is piped to other tools (e.g., git log | grep ...)
• Scripts that parse raw output
• Commands where you need the exact full output

If rtk fails:

Fall back to the bare command. Never block a task because of compression.

Check savings:

rtk gain           # current session
rtk gain --global  # all-time stats
