What this skill does

# Flexport Performance Tuning

## Overview

Optimize Flexport API integration performance. The API is rate-limited and serves logistics data that changes infrequently (shipments update hourly, products rarely). Cache aggressively for reads, batch writes, and use maximum page sizes.

## Instructions

### Step 1: Maximize Page Size

```typescript
// Default per=25. Use per=100 (max) to reduce API calls by 4x
async function fetchAllShipments(): Promise<Shipment[]> {
  const all: Shipment[] = [];
  let page = 1;
  while (true) {
    const res = await flexport(`/shipments?per=100&page=${page}`);
    all.push(...res.data.records);
    if (res.data.records.length < 100) break;
    page++;
  }
  return all;
  // 1000 shipments = 10 API calls instead of 40
}
```

### Step 2: Cache Responses

```typescript
import { LRUCache } from 'lru-cache';

const cache = new LRUCache<string, any>({
  max: 500,
  ttl: 5 * 60 * 1000,  // 5 min for shipment data
});

// Products change rarely — cache longer
const productCache = new LRUCache<string, any>({
  max: 1000,
  ttl: 60 * 60 * 1000,  // 1 hour
});

async function cachedFlexport(path: string, ttlCache = cache): Promise<any> {
  const cached = ttlCache.get(path);
  if (cached) return cached;
  const data = await flexport(path);
  ttlCache.set(path, data);
  return data;
}
```

### Step 3: Parallel Requests with Concurrency Control

```typescript
import PQueue from 'p-queue';

const queue = new PQueue({ concurrency: 5, interval: 1000, intervalCap: 10 });

// Fetch details for multiple shipments in parallel
async function enrichShipments(ids: string[]) {
  return Promise.all(
    ids.map(id => queue.add(() => flexport(`/shipments/${id}`)))
  );
}
```

### Step 4: Webhook-Driven Cache Invalidation

```typescript
// Instead of polling, invalidate cache on webhook events
async function handleWebhook(event: any) {
  if (event.type.startsWith('shipment.')) {
    cache.delete(`/shipments/${event.data.shipment_id}`);
    cache.delete('/shipments');  // Invalidate list cache
  }
  if (event.type.startsWith('product.')) {
    productCache.delete(`/products/${event.data.product_id}`);
  }
}
```

## Performance Targets

| Metric | Target | Strategy |
|--------|--------|----------|
| Shipment list load | < 500ms | Cache with 5min TTL |
| Product lookup | < 100ms | Cache with 1hr TTL |
| Bulk shipment fetch | < 3s for 100 | Parallel with p-queue |
| Dashboard refresh | < 2s | Stale-while-revalidate |

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.

Included

Invoke Alibaba Cloud Apsara Data Agent for Analytics via CLI to perform natural language-driven data analysis on enterprise databases. Data Agent for Analytics is an intelligent data analysis agent developed by Alibaba Cloud Database team for enterprise users. It automatically completes requirement analysis, data understanding, analysis insights, and report generation based on natural language descriptions. This tool supports: discovering data resources (instances/databases/tables) managed in DMS, initiating query or deep analysis sessions, real-time progress tracking, and retrieving analysis conclusions and generated reports. Use this Skill when users need to query databases, analyze data trends, generate data reports, ask questions in natural language, or mention "Data Agent", "data analysis", "database query", "SQL analysis", "data insights".

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.
