Non-functional advisory components have been removed.\n\n---\n\n## Components\n\n### 1. Context Hook (`token-context`)\n\n**Event:** `agent:bootstrap`\n\nFilters which workspace files are loaded based on message complexity.\n\n**Config:** `~/.openclaw/hooks/token-context/config.json`\n\n```json\n{\n  \"enabled\": true,\n  \"logLevel\": \"info\",\n  \"dryRun\": false,\n  \"files\": {\n    \"simple\": [\"SOUL.md\", \"IDENTITY.md\"],\n    \"standard\": [\"SOUL.md\", \"IDENTITY.md\", \"USER.md\"],\n    \"complex\": [\"SOUL.md\", \"IDENTITY.md\", \"USER.md\", \"TOOLS.md\", \"AGENTS.md\", \"MEMORY.md\", \"HEARTBEAT.md\"]\n  }\n}\n```\n\n**How it works:**\n- Extracts the user's latest message\n- Classifies complexity (simple/standard/complex)\n- Keeps only allowed files, discards the rest\n- Sets `context.bootstrapFiles` to the filtered list\n\n**Savings:**\n- Simple greetings → 2 files (99% token reduction)\n- Standard tasks → 3 files (90%+ reduction)\n- Complex tasks → all files (full context)\n\n**Rationale:** Simple messages don’t need documentation, memory logs, or tool references. Only identity and personality are required.\n\n### 2. Heartbeat Optimizer (`token-heartbeat`)\n\n**Event:** `agent:bootstrap` (for heartbeat polls)\n\nOptimizes heartbeat check schedule to dramatically reduce API calls.\n\n**Config:** `~/.openclaw/hooks/token-heartbeat/config.json`\n\n```json\n{\n  \"enabled\": true,\n  \"intervals\": {\n    \"email\": 7200,\n    \"calendar\": 14400,\n    \"weather\": 14400,\n    \"monitoring\": 7200\n  },\n  \"quietHours\": { \"start\": 23, \"end\": 8 }\n}\n```\n\n**How it works:**\n- Determines if enough time has elapsed since last check\n- Skips checks that are not due\n- Honors quiet hours (23:00–08:00 by default)\n- Returns `HEARTBEAT_OK` when nothing needs checking\n\n**Optimization Table:**\n\n| Check | Default Interval | Optimized | Reduction |\n|-------|------------------|-----------|-----------|\n| Email | 60 min | 120 min | 50% |\n| Calendar | 60 min | 240 min | 75% |\n| Weather | 60 min | 240 min | 75% |\n| Monitoring | 30 min | 120 min | 75% |\n\n**Result:** 48 checks/day → 12 checks/day (**75% fewer API calls**)\n\n### 3. Shared Module (`token-shared`)\n\nPure functions used by both hooks:\n- `classifyComplexity(message)` → complexity level\n- `getAllowedFiles(level, config)` → file list\n- `isValidFileName(name)` → path traversal protection\n- `loadConfigCached(logFn)` → 60s TTL config caching\n- Maybe/Either patterns (no exceptions for control flow)\n\n---\n\n## External Endpoints\n\nThis skill does **not** call any external network endpoints. All operations are local to your machine.\n\n---\n\n## Security & Privacy\n\n- **100% local execution** – No data leaves your system.\n- **No external telemetry** – No calls to third‑party servers.\n- **Configuration** read only from local hook configs.\n- **File validation** prevents path traversal attacks.\n- **No environment secrets** required.\n\n---\n\n## Model Invocation Note\n\nHooks run automatically:\n\n- `token-context` runs on every `agent:bootstrap` (every user message).\n- `token-heartbeat` runs on heartbeat polls.\nNo manual intervention needed after enabling the hooks.\n\n---\n\n## Trust Statement\n\nBy 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.\n\n---\n\n## CLI Commands\n\nAfter installation, the `tokenqrusher` command is available.\n\n### `tokenqrusher context <prompt>`\n\nRecommends which context files should be loaded for a given prompt.\n\n```bash\n$ tokenqrusher context \"hi\"\nComplexity: simple (confidence: 95%)\nFiles: SOUL.md, IDENTITY.md\nSavings: 71%\n```\n\n### `tokenqrusher status [--verbose]`\n\nShows system status.\n\n```bash\n$ tokenqrusher status\n=== tokenQrusher Status ===\n\nHooks:\n  ✓ token-context   (Filters context)\n  ✓ token-heartbeat (Optimizes heartbeat)\n```\n\n### `tokenqrusher install [--hooks] [--all]`\n\nInstalls/enables hooks.\n\n```bash\n$ tokenqrusher install --hooks\n✓ Enabled: token-context\n✓ Enabled: token-heartbeat\n```\n\n---\n\n## Configuration\n\nAll hook configs are JSON files stored in:\n`~/.openclaw/hooks/<hook-name>/config.json`\n\nYou can edit these to customize behavior (e.g., adjust file lists, intervals, or quiet hours). Changes are reloaded after 60 seconds (config cache TTL).\n\n---\n\n## Design Principles\n\n- **Deterministic** – Same input → same output.\n- **Pure functions** – No hidden side effects.\n- **Immutability** – Frozen data structures.\n- **No exceptions for control flow** – Uses Result/Either types.\n- **Thread‑safe** – RLock protected shared state.\n- **Exhaustive typing** – Full type hints.\n\n---\n\n## Performance\n\n| Operation | Latency | Memory |\n|-----------|---------|--------|\n| Context classification | <1 ms | <1 MB |\n| Heartbeat check | <0.5 ms | <0.5 MB |\n\nNegligible overhead per agent message.\n\n---\n\n## Troubleshooting\n\n### Hook not loading?\n\n```bash\n# Check status\nopenclaw hooks list\n\n# Should show \"✓ ready\" next to token-context and token-heartbeat\n\n# Enable if missing\nopenclaw hooks enable token-context\nopenclaw hooks enable token-heartbeat\n\n# Restart gateway\nopenclaw gateway restart\n```\n\n### Changes not taking effect?\n\nConfig cache TTL is 60 seconds. Restart the gateway for immediate effect.\n\n---\n\n## Migration from v2.0.x\n\nv2.1.0 removes non‑functional components. If upgrading:\n\n1. Disable and remove old hooks:\n   ```bash\n   openclaw hooks disable token-model\n   openclaw hooks disable token-usage\n   openclaw hooks disable token-cron\n   rm -rf ~/.openclaw/hooks/token-model\n   rm -rf ~/.openclaw/hooks/token-usage\n   rm -rf ~/.openclaw/hooks/token-cron\n   ```\n\n2. Update the skill:\n   ```bash\n   clawhub update tokenQrusher\n   ```\n\n3. Re‑install remaining hooks:\n   ```bash\n   tokenqrusher install --hooks\n   ```\n\n4. Restart gateway:\n   ```bash\n   openclaw gateway restart\n   ```\n\n**Removed commands:** `tokenqrusher model`, `budget`, `usage`, `optimize`. They no longer exist.\n\n---\n\n## License\n\nMIT.
