This is a solid, actionable skill with excellent executable code examples covering multiple patterns and both recommended approaches. Its main weaknesses are the lack of validation/verification steps (how to confirm extractors are working correctly) and the monolithic structure that could benefit from splitting common patterns into separate files. Some redundancy between the decision table and the 'Two Approaches' summary section adds unnecessary tokens.
Suggestions
Add a verification/validation section showing how to confirm an extractor is registered and producing lineage events (e.g., checking Airflow logs for OpenLineage output, using the OpenLineage API, or inspecting the Astro Lineage tab).
Extract the 'Common Patterns' section (SQL, file transfer, dynamic lineage) into a separate PATTERNS.md file and reference it from the main skill to improve progressive disclosure.
Remove the redundant 'Two Approaches' section since the decision table already covers when to use each approach — just link directly to the detailed sections.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is reasonably well-structured but includes some unnecessary verbosity: the introductory sentence restates the description, the 'Two Approaches' section redundantly summarizes what was already covered in the decision table, and some patterns (like the SQL parsing example with placeholder logic) add bulk without full value. The Astro-specific paragraph is tangential. | 2 / 3 |
Actionability | The skill provides fully executable, copy-paste-ready code examples for both approaches (OpenLineage methods and custom extractors), concrete registration commands, unit test examples, and specific import paths. The common pitfalls section includes concrete bad/good code comparisons. | 3 / 3 |
Workflow Clarity | The decision table and precedence rules provide good guidance on which approach to use, and the extraction methods are clearly sequenced. However, there are no explicit validation/verification steps — no guidance on how to verify the extractor is working, no feedback loop for testing lineage events appear correctly, and no checkpoint after registration to confirm the extractor is picked up. | 2 / 3 |
Progressive Disclosure | The content is well-organized with clear sections and tables, but it's a long monolithic document (~300 lines) with no bundle files to offload detailed patterns or reference material. The common patterns section (SQL, file transfer, dynamic) could be split into separate reference files. The external link to the OpenLineage developer guide is helpful but the skill itself could benefit from splitting. | 2 / 3 |
