Validate and debug Vercel AI SDK provider configurations including API keys, environment setup, model compatibility, and rate limiting. Use when encountering provider errors, authentication failures, API key issues, missing environment variables, model compatibility problems, rate limiting errors, or when user mentions provider setup, configuration debugging, or SDK connection issues.

What this skill does


# Provider Configuration Validator

**Purpose:** Autonomously validate, diagnose, and fix Vercel AI SDK provider configurations.

**Activation Triggers:**
- API errors (401, 403, 429, 404)
- Missing/invalid API keys
- Package installation issues
- Model compatibility errors
- Environment variable problems
- Import/connection failures

**Key Resources:**
- `scripts/validate-provider.sh` - Full validation (packages, keys, env)
- `scripts/check-model-compatibility.sh` - Validate model names
- `scripts/generate-fix.sh` - Generate fixes for common issues
- `scripts/test-provider-connection.sh` - Test real API connection
- `examples/troubleshooting-guide.md` - Comprehensive troubleshooting (10+ scenarios)
- `templates/` - .env, .gitignore, error handler code templates

## Diagnostic Workflow

### 1. Detect Issue Type

Identify error from symptoms:
- **401/403**: Invalid API key → Check key format and env var
- **429**: Rate limiting → Add retry logic
- **404/model_not_found**: Invalid model → Validate model name
- **Cannot find module**: Missing package → Install provider SDK
- **Missing env var**: No .env → Create .env file
- **Import error**: Wrong syntax → Fix imports for framework

### 2. Run Validation Script

```bash
# Main validation - checks everything
./scripts/validate-provider.sh <provider>

# Examples:
./scripts/validate-provider.sh openai
./scripts/validate-provider.sh anthropic
```

**Checks performed:**
- ✅ Provider package installed (correct version)
- ✅ Core SDK (`ai`) installed
- ✅ .env file exists
- ✅ API key set with correct format
- ✅ .env in .gitignore (security)

### 3. Validate Model Name (if applicable)

```bash
./scripts/check-model-compatibility.sh <provider> <model>

# Examples:
./scripts/check-model-compatibility.sh openai gpt-4o
./scripts/check-model-compatibility.sh anthropic claude-sonnet-4-5-20250929
```

Shows valid models if name is wrong, suggests closest matches.

### 4. Generate Fixes

```bash
./scripts/generate-fix.sh <issue-type> <provider>

# Issue types:
# - missing-api-key      → Creates .env with correct format
# - wrong-format         → Shows valid key format
# - missing-package      → Installs provider package
# - model-compatibility  → Lists valid models
# - rate-limiting        → Adds retry helper with exponential backoff
# - import-error         → Fixes import statements
```

### 5. Test Connection

```bash
# Verify API credentials work
./scripts/test-provider-connection.sh <provider>
```

Makes real API call with minimal tokens to verify setup.

## Provider-Specific Info

**OpenAI:**
- Package: `@ai-sdk/openai`
- Env: `OPENAI_API_KEY`
- Format: `sk-proj-...` or `sk-...`
- Models: gpt-4o, gpt-4o-mini, gpt-4, gpt-3.5-turbo

**Anthropic:**
- Package: `@ai-sdk/anthropic`
- Env: `ANTHROPIC_API_KEY`
- Format: `sk-ant-api03-...`
- Models: claude-sonnet-4-5-20250929, claude-opus-4-20250514

**Google:**
- Package: `@ai-sdk/google`
- Env: `GOOGLE_GENERATIVE_AI_API_KEY`
- Format: `AIza...`
- Models: gemini-1.5-pro, gemini-1.5-flash

**xAI:**
- Package: `@ai-sdk/xai`
- Env: `XAI_API_KEY`
- Format: `xai-...`
- Models: grok-beta, grok-vision-beta

## Common Fixes

### Missing API Key
```bash
# Create .env with correct structure
./scripts/generate-fix.sh missing-api-key openai

# Then add actual key from provider dashboard
```

### Wrong Model Name
```bash
# Check valid models
./scripts/check-model-compatibility.sh anthropic claude-v3-opus
# Shows: Did you mean? → claude-opus-4-20250514
```

### Rate Limiting
```bash
# Generate retry helper
./scripts/generate-fix.sh rate-limiting openai
# Creates retryHelper.ts with exponential backoff
```

### Package Not Installed
```bash
# Install provider package
./scripts/generate-fix.sh missing-package anthropic
# Runs: npm install ai @ai-sdk/anthropic
```

## Resources

**Scripts:** All scripts in `scripts/` directory are executable and documented in README.md

**Templates:** `templates/` contains .env, .gitignore, and error-handler-template.ts

**Examples:** `examples/troubleshooting-guide.md` has detailed solutions for 10+ scenarios including CORS, streaming, TypeScript, and provider-specific issues

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.
