Token Optimizer

OpenClaw Token Optimizer

Reduce OpenClaw token usage and API costs by 50-80%

An OpenClaw skill for smart model routing, lazy context loading, optimized heartbeats, budget tracking, and native OpenClaw 2026.2.15 features (session pruning, bootstrap size limits, cache TTL alignment).

    "load": {
      "extraDirs": ["~/.openclaw/skills/openclaw-token-optimizer"]
    }
  }
}

One-line install prompt for your agent

"Install the OpenClaw Token Optimizer skill from https://clawhub.ai/Asif2BD/openclaw-token-optimizer — or if ClawHub isn't available, clone https://github.com/Asif2BD/OpenClaw-Token-Optimizer and add the path to skills.load.extraDirs in openclaw.json"

✨ What's New in v1.4.x (OpenClaw 2026.2.15)

Three native config patches that work today with zero external dependencies:

Session Pruning

Auto-trim old tool results when the Anthropic cache TTL expires — reduces cache re-write costs.

{ "agents": { "defaults": { "contextPruning": { "mode": "cache-ttl", "ttl": "5m" } } } }

Bootstrap Size Limits

Cap workspace file injection into the system prompt (20-40% reduction for large workspaces).

{ "agents": { "defaults": { "bootstrapMaxChars": 10000, "bootstrapTotalMaxChars": 15000 } } }

Cache Retention for Opus

Amortize cache write costs on long Opus sessions.

{ "agents": { "defaults": { "models": { "anthropic/claude-opus-4-5": { "params": { "cacheRetention": "long" } } } } } }

Cache TTL Heartbeat Alignment

Keep the Anthropic 1h prompt cache warm — avoid the re-write penalty.

python3 scripts/heartbeat_optimizer.py cache-ttl
# → recommended_interval: 55min (3300s)

---

🛠️ Quick Start

1. Context optimization (biggest win):

python3 scripts/context_optimizer.py recommend "hi, how are you?"
# → Load only 2 files, skip everything else → ~80% savings

2. Model routing:

python3 scripts/model_router.py "design a microservices architecture"
# → Complex task → Opus
python3 scripts/model_router.py "thanks!"
# → Simple ack → Sonnet (cheapest available)

3. Optimized heartbeat:

cp assets/HEARTBEAT.template.md ~/.openclaw/workspace/HEARTBEAT.md
python3 scripts/heartbeat_optimizer.py plan

4. Token budget check:

python3 scripts/token_tracker.py check

5. Cache TTL alignment:

python3 scripts/heartbeat_optimizer.py cache-ttl
# Set heartbeat to 55min to keep Anthropic 1h cache warm

🔒 Security

All scripts are local-only — no network calls, no subprocess spawning, no system modifications. See SECURITY.md for full per-script audit.

Verify integrity:

cd ~/.openclaw/skills/openclaw-token-optimizer
sha256sum -c .clawhubsafe

Quick audit (should return nothing):

grep -r "urllib\|requests\|socket\|subprocess\|curl\|wget" scripts/
