Identify Top Key Values

This skill is used to inspect the actual data flowing into RT 2.0 event tables and analyze the distribution of stitching key values. It helps debug ID stitching issues by showing the most common values for each configured stitching key, including nulls and empty values that might cause problems. This is what's seen in plazma and may not be different than what the rt system ignores by configuration.

Use this skill when you want to understand:

• What ID values are actually present in your event data
• Distribution patterns of stitching keys
• Data quality issues (nulls, test values, invalid formats)

Requirements

In order to analyze key values we need:

1. Parent segment ID - The RT-enabled parent segment to inspect
2. Correctly configured tdx CLI or Treasure Data MCP server (@treasuredata/mcp-server)
3. API key with database access to query the event tables
4. Existing RT configuration with event tables and stitching keys configured
