# Hex Cost Tuning

## Overview

Hex pricing combines per-seat licensing with compute-based charges for notebook runs and data connections. Each scheduled or ad-hoc notebook execution consumes compute credits proportional to query complexity and data volume processed. Organizations running dozens of notebooks on hourly schedules — many producing identical results from unchanged data — accumulate unnecessary compute costs. Caching run results, optimizing schedules, and consolidating redundant notebooks are the highest-leverage cost reduction strategies.

## Cost Breakdown

| Component | Cost Driver | Optimization |
|-----------|------------|--------------|
| Seat licenses | Per-user/month (Team: $28/user) | Audit active editors quarterly; move viewers to free tier |
| Notebook runs | Compute per scheduled or manual execution | Cache results for unchanged data; extend run intervals |
| Data connections | Active warehouse/database connections | Consolidate overlapping connections; remove unused ones |
| Scheduled runs | Cron-triggered executions across all projects | Audit schedules — reduce frequency for stable data |
| API calls | Admin and Run API requests | Batch API operations; use cached results endpoint |

## API Call Reduction

```typescript
class HexRunOptimizer {
  private resultCache = new Map<string, { data: any; timestamp: number }>();
  private dataHashes = new Map<string, string>();

  async runIfChanged(projectId: string, runFn: () => Promise<any>): Promise<any> {
    const currentHash = await this.getSourceDataHash(projectId);
    if (this.dataHashes.get(projectId) === currentHash) {
      const cached = this.resultCache.get(projectId);
      if (cached) return cached.data; // Source unchanged — serve cached result
    }
    const result = await runFn();
    this.resultCache.set(projectId, { data: result, timestamp: Date.now() });
    this.dataHashes.set(projectId, currentHash);
    return result;
  }

  private async getSourceDataHash(projectId: string): Promise<string> {
    const res = await fetch(`/api/v1/project/${projectId}/status`);
    return (await res.json()).sourceDataHash;
  }
}
```

## Usage Monitoring

```typescript
class HexCostMonitor {
  private runs = new Map<string, number[]>();
  private weeklyBudget = 500; // max runs per week

  recordRun(projectId: string): void {
    const timestamps = this.runs.get(projectId) || [];
    timestamps.push(Date.now());
    this.runs.set(projectId, timestamps);
  }

  getWeeklyReport(): { totalRuns: number; byProject: Record<string, number> } {
    const weekAgo = Date.now() - 7 * 24 * 60 * 60 * 1000;
    const byProject: Record<string, number> = {};
    let total = 0;
    for (const [id, stamps] of this.runs) {
      const count = stamps.filter(t => t > weekAgo).length;
      byProject[id] = count;
      total += count;
    }
    return { totalRuns: total, byProject };
  }
}
```

## Cost Optimization Checklist

- [ ] Cache notebook results with `updateCacheResult: true`
- [ ] Skip re-runs when source data is unchanged
- [ ] Audit scheduled run frequencies — extend intervals for stable data
- [ ] Move read-only users from Team to free viewer tier
- [ ] Consolidate duplicate notebooks querying the same data
- [ ] Remove unused data connections
- [ ] Set weekly run budget alerts at 80% threshold
- [ ] Identify overrun projects (>20 runs/week) for schedule review

## Error Handling

| Issue | Cause | Fix |
|-------|-------|-----|
| Compute costs spiking | Hourly schedules on notebooks with daily-changing data | Extend schedule to match data refresh cadence |
| Stale cached results | Source data changed but cache not invalidated | Use source data hash comparison before serving cache |
| API rate limit (429) | Too many concurrent run triggers | Queue runs with concurrency limit of 3 |
| Unused notebooks accruing runs | Abandoned projects still on schedule | Audit and disable schedules for inactive projects |
| Connection pool exhausted | Too many simultaneous data source queries | Consolidate connections; stagger scheduled run times |

cupynumeric-migration-readiness

Included

Pre-migration readiness assessor for porting NumPy to cuPyNumeric. Use BEFORE substantial porting work begins when the user asks whether code will scale on GPU, whether they should migrate to cuPyNumeric, which NumPy patterns transfer cleanly, what must be refactored before porting, or mentions pre-port assessment, scaling analysis, or refactor planning. Inspect the user's source code, look up NumPy usage, cross-reference the cuPyNumeric API support manifest, and distinguish distributed-scaling-friendly patterns from blockers such as unsupported APIs, scalar synchronization, host round-trips, Python/object-heavy control flow, shape/data-dependent branching, and in-place mutation hazards. Produce a verdict of READY, LIGHT REFACTOR, SIGNIFICANT REFACTOR, or NOT RECOMMENDED, with concrete refactor pointers.

token-optimizer

Included

Reduce OpenClaw token usage and API costs through smart model routing, heartbeat optimization, budget tracking, and native 2026.2.15 features (session pruning, bootstrap size limits, cache TTL alignment). Use when token costs are high, API rate limits are being hit, or hosting multiple agents at scale. The 4 executable scripts (context_optimizer, model_router, heartbeat_optimizer, token_tracker) are local-only — no network requests, no subprocess calls, no system modifications. Reference files (PROVIDERS.md, config-patches.json) document optional multi-provider strategies that require external API keys and network access if you choose to use them. See SECURITY.md for full breakdown.
