RTK Optimizer Skill

Purpose: Automatically suggest RTK wrappers for high-verbosity commands to reduce token consumption.

How It Works

  1. Detect high-verbosity commands in user requests
  2. Suggest RTK wrapper if applicable
  3. Execute with RTK when user confirms
  4. Track savings over session

Supported Commands

Git (>70% reduction)

  • git log
    → 
    rtk git log
    (92.3% reduction)
  • git status
    → 
    rtk git status
    (76.0% reduction)
  • find
    → 
    rtk find
    (76.3% reduction)

Medium-Value (50-70% reduction)

  • git diff
    → 
    rtk git diff
    (55.9% reduction)
  • cat <large-file>
    → 
    rtk read <file>
    (62.5% reduction)

JS/TS Stack (70-90% reduction)

  • pnpm list
    → 
    rtk pnpm list
    (82% reduction)
  • pnpm test
    / 
    vitest run
    → 
    rtk vitest run
    (90% reduction)

Rust Toolchain (80-90% reduction)

  • cargo test
    → 
    rtk cargo test
    (90% reduction)
  • cargo build
    → 
    rtk cargo build
    (80% reduction)
  • cargo clippy
    → 
    rtk cargo clippy
    (80% reduction)

Python & Go (90% reduction)

  • pytest
    → 
    rtk python pytest
    (90% reduction)
  • go test
    → 
    rtk go test
    (90% reduction)

GitHub CLI (79-87% reduction)

  • gh pr view
    → 
    rtk gh pr view
    (87% reduction)
  • gh pr checks
    → 
    rtk gh pr checks
    (79% reduction)

File Operations

  • ls
    → 
    rtk ls
    (condensed output)
  • grep
    → 
    rtk grep
    (filtered output)

Activation Examples

User: "Show me the git history" Skill: Detects 
git log
→ Suggests 
rtk git log
→ Explains 92.3% token savings
User: "Find all markdown files" Skill: Detects 
find
→ Suggests 
rtk find "*.md" .
→ Explains 76.3% savings

Installation Check

Before first use, verify RTK is installed:
bash
rtk --version  # Should output: rtk 0.16.0+
If not installed:
bash
# Homebrew (macOS/Linux)
brew install rtk-ai/tap/rtk

# Cargo (all platforms)
cargo install rtk

Usage Pattern

markdown
# When user requests high-verbosity command:

1. Acknowledge request
2. Suggest RTK optimization:
   "I'll use `rtk git log` to reduce token usage by ~92%"
3. Execute RTK command
4. Track savings (optional):
   "Saved ~13K tokens (baseline: 14K, RTK: 1K)"

Session Tracking

Optional: Track cumulative savings across session:
bash
# At session end
rtk gain  # Shows total token savings for session (SQLite-backed)

Edge Cases

  • Small outputs (<100 chars): Skip RTK (overhead not worth it)
  • Already using Claude tools: Grep/Read tools are already optimized
  • Multiple commands: Batch with RTK wrapper once, not per command

Configuration

Enable via CLAUDE.md:
markdown
## Token Optimization

Use RTK (Rust Token Killer) for high-verbosity commands:
- git operations (log, status, diff)
- package managers (pnpm, npm)
- build tools (cargo, go)
- test frameworks (vitest, pytest)
- file finding and reading

Metrics (Verified)

Based on real-world testing:
  • git log
    : 13,994 chars → 1,076 chars (92.3% reduction)
  • git status
    : 100 chars → 24 chars (76.0% reduction)
  • find
    : 780 chars → 185 chars (76.3% reduction)
  • git diff
    : 15,815 chars → 6,982 chars (55.9% reduction)
  • read file
    : 163,587 chars → 61,339 chars (62.5% reduction)
Average: 72.6% token reduction

Limitations

  • 446 stars on GitHub, actively maintained (30 releases in 23 days)
  • Not suitable for interactive commands
  • Rapid development cadence (check for breaking changes)

Recommendation

Use RTK for: git workflows, file operations, test frameworks, build tools, package managers Skip RTK for: small outputs, quick exploration, interactive commands
