# RTK Integration Analysis & Implementation Plan

## Executive Summary

**RTK (Rust Token Killer)** is a high-performance CLI proxy that reduces LLM token consumption by **60-90%** on common development commands. It achieves this through intelligent output filtering, compression, and smart routing of CLI commands.

### Key Metrics

- **Token Savings**: 60-90% average (up to 99% for specific commands)
- **Performance**: <10ms overhead per command
- **Architecture**: Single Rust binary, zero dependencies
- **Ecosystem**: 30+ command modules covering Git, JS/TS, Python, Go, Containers, and more

---

## Current UAP Status vs RTK Capabilities

### What UAP Already Has (v2.0.1)

✅ **MCP Router** - Token reduction via hierarchical routing (~98% token reduction)

- Exposes 2 meta-tools: `discover_tools`, `execute_tool`
- Hides individual tool definitions from LLM context
- Works at the MCP protocol level

### What RTK Brings (Complementary Layer)

✅ **CLI Output Filtering** - Direct command output compression

- Filters raw stdout/stderr before it reaches LLM
- Applies language-specific strategies (stats extraction, error grouping, deduplication)
- Works at the shell command execution level

---

## Strategic Integration Options

### Option 1: Parallel Implementation (Recommended)

```
┌────────────────────────────────────────────────────────────────────────┐
│                    TWO-LAYER TOKEN OPTIMIZATION                        │
└────────────────────────────────────────────────────────────────────────┘

Layer 1: MCP Router (UAP v2.0.1)
────────────────────────────────
LLM → [Discover Tools] → [Execute Tool] → Backend Services
           ↓                    ↓
      ~483 tokens        ~700 tokens
      Total: ~1,200 tokens

Layer 2: RTK CLI Proxy (New)
─────────────────────────────
Command Execution:
LLM → rtk git status → [Filter/Compress] → Shell → Git
                     ↓
              ~200 tokens (vs ~2,000 raw)
```

**Benefits**:

- **Synergy**: MCP Router reduces tool definition overhead; RTK reduces command output overhead
- **Coverage**: All token consumption vectors addressed (tool discovery + command execution)
- **Zero Conflict**: Independent layers with different scopes
- **Best of Both**: Rust performance (RTK) + TypeScript ecosystem (UAP)

**Estimated Combined Savings**: 95%+ total token reduction

---

### Option 2: RTK as UAP Subcommand

```bash
# Proposed syntax
uap rtk git status          # Uses RTK binary internally
uap rtk install             # Install RTK to ~/.local/bin/rtk
uap rtk gain              # Show token savings analytics
```

**Benefits**:

- Unified CLI experience
- Single installation command
- Integrated analytics dashboard

**Implementation Complexity**: Medium (requires bundling Rust binary)

---

### Option 3: Pure TypeScript Implementation

Re-implement RTK filtering logic in TypeScript/Node.js within UAP.

**Benefits**:

- No Rust dependency
- Easier maintenance for JS/TS team
- Single codebase

**Drawbacks**:

- Slower performance (Node.js vs Rust)
- Loss of <10ms overhead guarantee
- Larger binary size

**Estimated Performance**: ~50-100ms overhead (vs <10ms in RTK)

---

## Recommended Implementation: Option 1 (Parallel)

### Architecture Overview

```
┌────────────────────────────────────────────────────────────────────────┐
│                    UAP + RTK Integration                               │
└────────────────────────────────────────────────────────────────────────┘

User Workflow:

1. Install RTK via Homebrew or cargo
   $ brew install rtk

2. Initialize hook for Claude Code
   $ rtk init --global
   # Registers PreToolUse hook in ~/.claude/settings.json

3. UAP MCP Router runs in background
   $ uap mcp-router start &

4. All commands transparently optimized:
   - Git operations → RTK git (85-99% savings)
   - Tool discovery → MCP Router (~98% savings)
   - Test output → RTK test (90%+ savings)
```

## Performance Benchmarks (RTK)

### Typical Command Savings

| Command                   | Raw Tokens | RTK Tokens | Savings |
| ------------------------- | ---------- | ---------- | ------- |
| `git status`              | 2,000      | 400        | **80%** |
| `cat file.rs` (100 lines) | 40,000     | 12,000     | **70%** |
| `cargo test`              | 25,000     | 2,500      | **90%** |
| `npm test`                | 25,000     | 2,500      | **90%** |
| `git diff`                | 10,000     | 2,500      | **75%** |
| `docker logs <container>` | 8,000      | 800        | **90%** |

### Overhead Analysis

```
Command Execution Time:
┌───────────────────────────────────────────────────────────────┐
│ git status (raw)           │ 5ms execution + 2,000 tokens     │
│ rtk git status             │ 15ms execution + 400 tokens      │
│ Overhead                   │ +10ms (~2x slower, but 80% less │
│                           │               context)            │
└───────────────────────────────────────────────────────────────┘

Trade-off: 10ms delay vs 1,600 token savings = ~$0.003 cost reduction
(per million tokens @ $0.03/M)
```

uap mcp-router start &

# Step 5: Verify installation
uap token-savings  # Unified analytics
rtk gain           # RTK-specific stats
```

### Configuration Files

**RTK**: `~/.config/rtk/config.toml`

```toml
[tracking]
database_path = "~/.local/share/rtk/history.db"

[hooks]
exclude_commands = ["curl", "wget"]  # Skip these commands

[tee]
enabled = true  # Save full output on failure
mode = "failures"
```

**UAP**: `~/.opencode/config.json` (auto-created by `uap install opencode`)

```json
{
  "uapEnabled": true,
  "mcpRouterEnabled": true,
  "rtkIntegration": {
    "enabled": true,
    "path": "~/.local/bin/rtk",
    "autoDetect": true
  }
}
```

## Risk Assessment

### Low Risk Items ✅

- **Documentation Updates**: Safe to add RTK references
- **Installation Scripts**: Non-invasive, easy to revert
- **Analytics Dashboard**: Read-only integration with RTK data

### Medium Risk Items ⚠️

- **CLI Wrappers**: Requires careful error handling for missing RTK binary
- **Auto-detection**: May fail if RTK installed in non-standard location

### High Risk Items ❌

- **Custom UAP RTK Modules**: Could conflict with existing RTK modules
- **Bundling Rust Binary**: Increases package size, complicates distribution

---

## Recommendation & Next Steps

### Immediate Actions (Week 1)

1. **Update Documentation**
   - Add "RTK Integration" section to UAP README
   - Create installation guide for both tools
   - Document token savings expectations

2. **Create Installation Helper**

   ```bash
   # scripts/install-rtk.sh
   # Auto-detects OS and installs RTK via Homebrew/cargo
   ```

3. **Add `uap install rtk` Command**
   ```typescript
   // src/cli/rtk.ts
   export async function installRtk() {
     const installer = detectOS();
     await installer.run();
   }
   ```

### Short-term Goals (Weeks 2-4)

4. **Implement `uap rtk` Wrapper**
   - Pass-through to RTK binary
   - Auto-detection and installation prompts

5. **Create Unified Analytics**
   - Merge MCP Router + RTK stats
   - Add export functionality

### Long-term Vision (Months 2-3)

6. **Custom UAP RTK Modules**
   - Memory operations, task management, droid coordination

7. **Advanced Features**
   - Smart command suggestions based on usage patterns
   - Custom filter strategies for UAP-specific workflows

---

## Conclusion

**RTK and UAP MCP Router are complementary tools** that address different layers of token optimization:

- **MCP Router**: Reduces tool definition overhead at the protocol level (~98% savings)
- **RTK**: Compresses CLI command output before it reaches the LLM (60-90% savings)

**Recommended Approach**: Parallel implementation with unified analytics and CLI integration. This provides maximum token savings without architectural complexity or risk.

**Estimated Combined Savings**: 95%+ total token reduction across all LLM interactions.
