OpenRouter Config Validator

Comprehensive validation and testing utilities for OpenRouter API configuration, model availability, routing setup, and cost monitoring.

What This Skill Provides

1. API Key Validation: Format checking and connectivity testing
2. Model Availability Checking: Verify requested models are accessible
3. Routing Configuration Testing: Validate model routing and fallback chains
4. Environment Validation: Check .env file completeness and correctness
5. Fallback Testing: Test fallback chain execution and behavior
6. Provider Status Checking: Monitor provider availability and health
7. Usage Analysis: Track API usage patterns and cost optimization
8. Troubleshooting: Comprehensive diagnostic tools for common issues

Instructions

Phase 1: Identify Validation Need

Determine what needs validation:

• API key format and connectivity
• Model availability and access
• Routing configuration correctness
• Environment variable completeness
• Fallback chain behavior
• Provider health status
• Usage patterns and costs
• General troubleshooting

Phase 2: Run Appropriate Validation Script

Execute the relevant validation script from scripts/ directory:

API Key Validation:

bash scripts/validate-api-key.sh <api-key>

Model Availability Check:

bash scripts/check-model-availability.sh <model-id>

Routing Configuration Test:

bash scripts/test-routing.sh <config-file>

Environment Validation:

bash scripts/validate-env-config.sh <env-file>

Fallback Chain Testing:

bash scripts/test-fallback.sh <fallback-config>

Provider Status Check:

bash scripts/check-provider-status.sh <provider-name>

Usage Analysis:

bash scripts/analyze-usage.sh <date-range>

Comprehensive Troubleshooting:

bash scripts/troubleshoot.sh

Phase 3: Load Appropriate Template

Use templates from templates/ directory for configuration:

Environment Setup:

• templates/.env.template - Complete configuration template
• templates/.env.example - Minimal configuration example

Monitoring Configuration:

• templates/monitoring-config.json - X-Title and HTTP-Referer setup
• templates/budget-alerts.json - Cost alert configuration

Provider Preferences:

• templates/provider-preferences.json - Provider routing preferences

Phase 4: Reference Troubleshooting Examples

Check examples/ directory for common issue resolutions:

• examples/api-key-troubleshooting.md - API key issues
• examples/model-not-found.md - Model availability problems
• examples/rate-limiting.md - Rate limit handling
• examples/fallback-issues.md - Fallback chain debugging
• examples/cost-optimization.md - Cost reduction strategies
• examples/provider-errors.md - Provider-specific errors

Phase 5: Report Results

Summarize validation results:

• What was tested
• Issues found (if any)
• Recommended fixes
• Next steps

When Agents Should Use This Skill

Automatic triggers:

• Setting up new OpenRouter integration
• Debugging API connection failures
• Validating configuration before deployment
• Troubleshooting model access issues
• Analyzing unexpected API costs
• Testing fallback chain behavior
• Monitoring provider health

User-requested scenarios:

• "Validate my OpenRouter configuration"
• "Test if model X is available"
• "Why is my fallback chain not working?"
• "Check my API usage costs"
• "Troubleshoot OpenRouter connection"
• "Verify my routing configuration"

Validation Capabilities

API Key Validation

Routing Validation

• Model routing configuration
• Fallback chain structure
• Provider preference validation
• Cost optimization checks

Usage Analysis

• Request volume tracking
• Cost breakdowns by model
• Provider distribution
• Rate limit monitoring
• Budget alert configuration
