What this skill does

# Flexport Common Errors

## Overview

Quick reference for the most common Flexport API v2 errors. The API returns standard HTTP codes with JSON error bodies containing `code`, `message`, and sometimes `details` fields.

## Error Reference

### 401 Unauthorized — Invalid or Missing API Key

```json
{ "error": { "code": "UNAUTHORIZED", "message": "Invalid API key" } }
```

**Causes:** Missing `Authorization` header, expired JWT token, revoked API key.

**Fix:**

```bash
# Verify key is set
echo $FLEXPORT_API_KEY | head -c 10
# Test with cURL
curl -s -o /dev/null -w "%{http_code}" \
  -H "Authorization: Bearer $FLEXPORT_API_KEY" \
  -H "Flexport-Version: 2" \
  https://api.flexport.com/shipments?per=1
```

### 403 Forbidden — Insufficient Permissions

**Causes:** API key lacks required scope, IP whitelist blocking, sandbox key used on production.

**Fix:** Check key permissions in Flexport Portal > Settings > Developer. Ensure key scope includes the endpoint you are calling.

### 404 Not Found — Resource Does Not Exist

```json
{ "error": { "code": "NOT_FOUND", "message": "Shipment shp_xxx not found" } }
```

**Causes:** Wrong ID format, resource deleted, using test ID in production.

**Fix:** List resources first to get valid IDs:

```bash
curl -s -H "Authorization: Bearer $FLEXPORT_API_KEY" \
     -H "Flexport-Version: 2" \
     https://api.flexport.com/shipments?per=1 | jq '.data.records[0].id'
```

### 422 Unprocessable Entity — Validation Failed

```json
{ "error": { "code": "VALIDATION_ERROR", "message": "Invalid port code", "details": [...] } }
```

**Common validation failures:**

| Field | Issue | Fix |
|-------|-------|-----|
| `origin_port.code` | Not a valid UN/LOCODE | Use `CNSHA`, `USLAX`, `DEHAM` format |
| `hs_code` | Wrong format | Use 6-10 digit codes like `8479.89` |
| `cargo_ready_date` | In the past | Use future ISO date |
| `freight_type` | Unsupported value | Use `ocean`, `air`, or `trucking` |
| `incoterm` | Invalid | Use `FOB`, `CIF`, `EXW`, `DDP` |

### 429 Too Many Requests — Rate Limited

```json
{ "error": { "code": "RATE_LIMITED", "message": "Rate limit exceeded" } }
```

**Fix:** Check response headers and back off:

```typescript
function handleRateLimit(res: Response): number {
  const retryAfter = res.headers.get('Retry-After');
  const remaining = res.headers.get('X-RateLimit-Remaining');
  console.log(`Rate limited. Remaining: ${remaining}. Retry after: ${retryAfter}s`);
  return parseInt(retryAfter || '60') * 1000;
}
```

### 500/502/503 — Server Errors

**Causes:** Flexport internal issue, maintenance window, upstream provider failure.

**Fix:**

```bash
# Check Flexport status page
curl -s https://status.flexport.com/api/v2/status.json | jq '.status'
```

Retry with exponential backoff for transient 5xx errors. See `flexport-rate-limits`.

## Diagnostic Script

```bash
#!/bin/bash
echo "=== Flexport Diagnostics ==="
echo "API Key set: ${FLEXPORT_API_KEY:+YES}"
echo "Key prefix: ${FLEXPORT_API_KEY:0:8}..."
echo -n "API status: "
curl -s -o /dev/null -w "%{http_code}" \
  -H "Authorization: Bearer $FLEXPORT_API_KEY" \
  -H "Flexport-Version: 2" \
  https://api.flexport.com/shipments?per=1
echo ""
echo -n "Status page: "
curl -s https://status.flexport.com/api/v2/status.json | jq -r '.status.description'
```

## Escalation Path

1. Run diagnostic script above
2. Collect request ID from response headers (`X-Request-Id`)
3. Check [Flexport Status](https://status.flexport.com)
4. Contact Flexport support with request ID and error details

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.

alibabacloud-data-agent-skill

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.
