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

{
  "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

{
  "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:

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.

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

tokenqrusher status [--verbose]

Shows system status.

$ tokenqrusher status
=== tokenQrusher Status ===

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

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

Installs/enables hooks.

$ 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

Negligible overhead per agent message.

Troubleshooting

Hook not loading?

# 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:

   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:

   clawhub update tokenQrusher
   

3. Re‑install remaining hooks:

   tokenqrusher install --hooks
   

4. Restart gateway:

   openclaw gateway restart
   

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