When is the best time to run the recce-mcp-e2e skill?

It should be triggered after modifying recce/mcp_server.py, updating tool handlers, changing error classification logic, or as a final check before merging MCP-related PRs.

Do I need an existing dbt project to use this skill?

Yes, the skill requires a dbt project directory containing both target/manifest.json and target-base/manifest.json to perform comparative analysis.

What specifically does this skill verify in Recce?

It performs a full-stack verification of all 8 core MCP tools: lineage_diff, schema_diff, row_count_diff, query, query_diff, profile_diff, list_checks, and run_check.

How does it handle conflicts between local code and installed packages?

The skill automatically detects if recce-nightly is installed and configures the PYTHONPATH to prioritize the local repository source code during testing.

Seguridad y Pruebas

Automates full end-to-end verification of Recce MCP server tools against dbt projects to ensure data validation accuracy during PR reviews.

The Recce MCP E2E skill provides a comprehensive testing suite for developers working on the Recce data validation toolkit. It automates the verification of all eight MCP tools—including lineage diffs, schema comparisons, and row count checks—against live dbt projects. By validating both full-stack and single-environment modes, the skill ensures that code changes to the MCP server, tool handlers, or error classification logic are robust before merging, preventing regressions in data building and validation workflows.
