TokenQrusher

Token optimization system for OpenClaw reducing costs 50-80%

tokenQrusher Skill

Overview

tokenQrusher reduces OpenClaw API costs by 50-80% through:

1. Context Filtering – Loads only necessary workspace files (up to 99% reduction for simple messages)
2. Heartbeat Optimization – Reduces heartbeat API calls by 75%

This is the simplified, production-ready core. Non-functional advisory components have been removed.

Components

1. Context Hook (token-context)

Event: agent:bootstrap

Filters which workspace files are loaded based on message complexity.

Config: ~/.openclaw/hooks/token-context/config.json

json

{
  "enabled": true,
  "logLevel": "info",
  "dryRun": false,
  "files": {
    "simple": ["SOUL.md", "IDENTITY.md"],
    "standard": ["SOUL.md", "IDENTITY.md", "USER.md"],
    "complex": ["SOUL.md", "IDENTITY.md", "USER.md", "TOOLS.md", "AGENTS.md", "MEMORY.md", "HEARTBEAT.md"]
  }
}

How it works:

• Extracts the user's latest message
• Classifies complexity (simple/standard/complex)
• Keeps only allowed files, discards the rest
• Sets context.bootstrapFiles to the filtered list

Savings:

• Simple greetings → 2 files (99% token reduction)
• Standard tasks → 3 files (90%+ reduction)
• Complex tasks → all files (full context)

Rationale: Simple messages don’t need documentation, memory logs, or tool references. Only identity and personality are required.

2. Heartbeat Optimizer (token-heartbeat)

Event: agent:bootstrap (for heartbeat polls)

Optimizes heartbeat check schedule to dramatically reduce API calls.

Config: ~/.openclaw/hooks/token-heartbeat/config.json

json

{
  "enabled": true,
  "intervals": {
    "email": 7200,
    "calendar": 14400,
    "weather": 14400,
    "monitoring": 7200
  },
  "quietHours": { "start": 23, "end": 8 }
}

How it works:

• Determines if enough time has elapsed since last check
• Skips checks that are not due
• Honors quiet hours (23:00–08:00 by default)
• Returns HEARTBEAT_OK when nothing needs checking

Optimization Table:

Check	Default Interval	Optimized	Reduction
Email	60 min	120 min	50%
Calendar	60 min	240 min	75%
Weather	60 min	240 min	75%
Monitoring	30 min	120 min	75%

Result: 48 checks/day → 12 checks/day (75% fewer API calls)

3. Shared Module (token-shared)

Pure functions used by both hooks:

• classifyComplexity(message) → complexity level
• getAllowedFiles(level, config) → file list
• isValidFileName(name) → path traversal protection
• loadConfigCached(logFn) → 60s TTL config caching
• Maybe/Either patterns (no exceptions for control flow)

External Endpoints

This skill does not call any external network endpoints. All operations are local to your machine.

---

Security & Privacy

• 100% local execution – No data leaves your system.
• No external telemetry – No calls to third‑party servers.
• Configuration read only from local hook configs.
• File validation prevents path traversal attacks.
• No environment secrets required.

---

Model Invocation Note

Hooks run automatically:

• token-context runs on every agent:bootstrap (every user message).
• token-heartbeat runs on heartbeat polls. No manual intervention needed after enabling the hooks.

---

Trust Statement

By installing this skill, you trust that the code operates locally and does not transmit your workspace data. Review the open‑source implementation on GitHub before installing.

---

CLI Commands

After installation, the tokenqrusher command is available.

tokenqrusher context <prompt>

Recommends which context files should be loaded for a given prompt.

bash

$ tokenqrusher context "hi"
Complexity: simple (confidence: 95%)
Files: SOUL.md, IDENTITY.md
Savings: 71%

tokenqrusher status [--verbose]

Shows system status.

bash

$ tokenqrusher status
=== tokenQrusher Status ===

Hooks:
  ✓ token-context   (Filters context)
  ✓ token-heartbeat (Optimizes heartbeat)

tokenqrusher install [--hooks] [--all]

Installs/enables hooks.

bash

$ tokenqrusher install --hooks
✓ Enabled: token-context
✓ Enabled: token-heartbeat

---

Configuration

All hook configs are JSON files stored in: ~/.openclaw/hooks/<hook-name>/config.json

You can edit these to customize behavior (e.g., adjust file lists, intervals, or quiet hours). Changes are reloaded after 60 seconds (config cache TTL).

---

Design Principles

• Deterministic – Same input → same output.
• Pure functions – No hidden side effects.
• Immutability – Frozen data structures.
• No exceptions for control flow – Uses Result/Either types.
• Thread‑safe – RLock protected shared state.
• Exhaustive typing – Full type hints.

---

Performance

Operation	Latency	Memory
Context classification	<1 ms	<1 MB
Heartbeat check	<0.5 ms	<0.5 MB

Negligible overhead per agent message.

---

Troubleshooting

Hook not loading?

bash

# Check status
openclaw hooks list

# Should show "✓ ready" next to token-context and token-heartbeat

# Enable if missing
openclaw hooks enable token-context
openclaw hooks enable token-heartbeat

# Restart gateway
openclaw gateway restart

Changes not taking effect?

Config cache TTL is 60 seconds. Restart the gateway for immediate effect.

Migration from v2.0.x

v2.1.0 removes non‑functional components. If upgrading:

1. Disable and remove old hooks:

   bash

   openclaw hooks disable token-model
   openclaw hooks disable token-usage
   openclaw hooks disable token-cron
   rm -rf ~/.openclaw/hooks/token-model
   rm -rf ~/.openclaw/hooks/token-usage
   rm -rf ~/.openclaw/hooks/token-cron
   

2. Update the skill:

   bash

   clawhub update tokenQrusher
   

3. Re‑install remaining hooks:

   bash

   tokenqrusher install --hooks
   

4. Restart gateway:

   bash

   openclaw gateway restart
   

Removed commands: tokenqrusher model, budget, usage, optimize. They no longer exist.
