🛡️ Token Shield

AI token optimizer — compress prompts, enhance Flash model, smart routing. Save 80% tokens. Make free models work like paid ones.

🚀 Install

npm install -g token-shield

⚡ Quick Start

# 1. Initialize in your project
cd your-project
token-shield init

# 2. Hook into your AI tools (Claude Code, Cursor, Windsurf, Cline, Antigravity...)
token-shield install

# 3. Compress a prompt
token-shield compress "Hey could you please help me fix this JavaScript bug?"

# 4. View status + quota dashboard
token-shield status

🎯 Two Problems Solved

| Problem | Solution | |---------|----------| | Claude token limit finishes in 1-2 days | Prompt compression → limit lasts 4-5× longer | | Flash model (free, 5h reset) gives weak results | Flash Enhancer → 50% → 85% quality |

🧩 6-Layer System

| Layer | What it does | Saving | |-------|-------------|--------| | 1. Input Compression | Remove filler, prune history, extract relevant code | 40-80% input tokens | | 2. Project Intelligence | anatomy.md file index + mistake memory (cerebrum.md) | 80% file-reading tokens | | 3. Smart Routing | Flash (free) → Claude → escalate based on quota | Max free usage | | 4. CLI Proxy Wrapper | rtk-ai | Intercept console commands (npm test, git log) & summarize | ~90% terminal output tokens | | 5. Flash Enhancer | Add expert role + step-by-step + format for Flash model | +35% Flash quality | | 6. Caveman Mode | AI responds in compressed style (Lite/Full/Ultra) | 40-75% output tokens | | 7. Quality + Escalation | Score responses, auto-escalate bad Flash answers | Zero wasted tokens |

💻 Commands

token-shield init                    # Create .token-shield/ intelligence files
token-shield install                 # Inject hooks into AI tools

token-shield proxy "npm run test"    # Wraps noisy commands to suppress terminal token spam
                                   # Try wrapping git log, ls, or pytest!

token-shield compress "prompt"       # Compress + Flash enhance + route
token-shield status                  # Live quota + savings dashboard
token-shield dashboard               # Web dashboard at localhost:4242
token-shield uninstall               # Uninstall token-shield

🪝 AI Tool Support

token-shield install auto-detects and injects compression rules into:

| Tool | Config file | |------|------------| | Claude Code | CLAUDE.md | | Antigravity (Gemini) | GEMINI.md | | Cursor | .cursorrules | | Windsurf | .windsurf/rules.md | | Cline / Roo | .clinerules | | Any tool | AGENTS.md |

📁 Project Intelligence (.token-shield/)

After token-shield init, every project gets:

.token-shield/
├── anatomy.md    ← File index with token estimates (AI reads this, not source files)
├── cerebrum.md   ← Mistake memory (AI never repeats the same error)
├── memory.md     ← Session learnings
├── ledger.json   ← Lifetime token savings log
└── config.json   ← Settings (caveman level, quota timers)

anatomy.md tells AI what each file contains before reading it → 6-49× fewer file reads. cerebrum.md prevents the same mistake from happening twice → zero repeated errors.

🪨 Caveman Mode

Inspired by caveman (36k ⭐) — makes AI respond in compressed style:

Normal AI: "The reason your React component is re-rendering is likely because
            you're creating a new object reference on each render cycle..."
           → 69 tokens

🪶 Lite:   "Component re-renders: new object ref each render. Use useMemo."
           → 41 tokens  (40% saved)

🪨 Full:   "New obj ref each render. Inline prop = new ref = re-render. useMemo."
           → 24 tokens  (65% saved)

🔥 Ultra:  "Inline obj → new ref → re-render. useMemo."
           → 17 tokens  (75% saved)

⚡ Flash Model Enhancer

Flash model is free (resets every 5h) but gives weaker results than Claude. Token Shield enhances prompts for Flash automatically:

Before → Flash:  "Fix my React bug"
After  → Flash:  "You are a Senior React/Next.js developer.
                  Think step by step before answering.
                  Format: (1) Root cause (2) Fix with code (3) One-line explanation.
                  Fix my React bug"

Result: Flash quality goes from ~50% → ~85% of Claude quality. Free.

📊 Expected Results

| Metric | Before | After | |--------|--------|-------| | Claude limit duration | 1-2 days | 5-7 days | | Input tokens per prompt | 847 avg | ~150 avg | | Flash result quality | 50% | 85% | | Output tokens (Ultra) | 200 avg | ~50 avg |

🏗️ Built With Inspiration From

• caveman — output compression
• openwolf — project anatomy + memory
• code-review-graph — codebase indexing

Token Shield adds: Flash Enhancer + Smart Routing + Model Escalation — features none of them have.

🔐 Privacy

• 100% local processing — no server, no cloud
• API keys never transmitted anywhere
• .token-shield/ stays in your project folder
• Zero telemetry, zero tracking
