name: check-live-stations description: Analyze live weather station integrations, validate data sources, and identify spots missing live conditions

Check Live Stations Skill

Analyze live weather data sources in FetchCurrentConditions strategies and cross-reference with spots.json to identify coverage and issues.

Instructions

Perform the following analysis and report all findings.

1. Discover All Strategies

Scan src/main/java/com/github/pwittchen/varun/service/live/strategy/ for all FetchCurrentConditionsStrategy*.java files.

For each strategy, extract:

• Class name
• Windguru ID(s) it handles (from canProcess() method or ID constants/maps)
• Data source URL(s)
• Data format (JSON, plain text, HTML scraping)
• Provider name (from class comments or URL domain)

2. Load Spots Data

Read src/main/resources/spots.json and extract:

• Spot name
• Country
• Windguru ID (from windguruUrl, extract numeric ID)
• Fallback Windguru ID if present (from windguruFallbackUrl)

3. Cross-Reference Coverage

For each spot in spots.json:

1. Determine if any strategy can process its Windguru ID
2. Mark spots as "has live data" or "no live data"

4. Test Live Data Sources

For each unique data source URL found in strategies:

1. Attempt to fetch the URL using curl (with 10s timeout)
2. Check HTTP response code
3. Verify response contains expected data markers (non-empty, valid format)

5. Analyze Strategy Patterns

For each strategy, document:

• Parsing method (regex, JSON, HTML table extraction)
• Fields extracted (wind speed, gusts, direction, temperature, timestamp)
• Unit conversions performed (m/s to knots, etc.)
• Error handling approach

Output Format

Generate a report in this format:

Copy## Live Weather Stations Analysis Report

### Summary
- Total strategies: X
- Total spots: Y
- Spots with live data: Z (W%)
- Spots without live data: N

### Strategy Inventory

| Strategy Class | Provider | WG IDs | Data URL | Format |
|----------------|----------|--------|----------|--------|
| ...            | ...      | ...    | ...      | ...    |

### Coverage by Country

| Country | Total Spots | With Live Data | Without Live Data |
|---------|-------------|----------------|-------------------|
| Poland  | X           | Y              | Z                 |
| ...     | ...         | ...            | ...               |

### Spots WITH Live Data Integration

| Spot Name | Country | WG ID | Strategy | Data Source |
|-----------|---------|-------|----------|-------------|
| ...       | ...     | ...   | ...      | ...         |

### Spots WITHOUT Live Data Integration

These spots only have forecast data and could benefit from live weather station integration:

| Spot Name | Country | WG ID | Potential Sources |
|-----------|---------|-------|-------------------|
| ...       | ...     | ...   | (suggest if known) |

### Data Source Health Check

| URL | Status | Response Time | Notes |
|-----|--------|---------------|-------|
| ... | OK/FAIL| Xms           | ...   |

### Issues Found

#### Critical (data sources unreachable)
- [Strategy] URL not responding: url

#### Warnings (potential improvements)
- [Spot] Could add live data from nearby station
- [Strategy] Missing gust data extraction

### Recommendations

1. Priority spots for live data integration (high-traffic locations)
2. Nearby stations that could be leveraged
3. Strategy improvements or consolidation opportunities

Execution Steps

1. Use Glob to find all strategy files in the strategy directory
2. Use Read to analyze each strategy file
3. Use Read to load spots.json
4. Use Bash with curl to test each data source URL
5. Cross-reference and generate the report
6. Provide actionable recommendations

Notes

• Windguru IDs are extracted from URLs like https://www.windguru.cz/500760 -> 500760
• Some spots use windguruFallbackUrl when windguruUrl is empty (generated IDs)
• Strategies may handle multiple spots (e.g., WiatrKadynyStations handles 4 spots)
• Data sources may be temporarily offline; distinguish between transient and permanent failures
