This is a strong, highly actionable skill that provides a clear step-by-step implementation checklist for Cosmos + dbt Core integration. Its main strengths are the executable code examples at every step and the decision tables that map user constraints to configuration choices. The primary weakness is length—the body could be more concise by moving some of the longer code examples (especially Option C and operational extras) to referenced files, improving both conciseness and progressive disclosure.
Suggestions
Move Option C (individual operators example) and the 'Setting Dependencies on Individual Cosmos Tasks' section to a referenced file like 'reference/cosmos-advanced-patterns.md' to reduce body length.
Consider moving Appendix B (Operational Extras) to the referenced 'reference/cosmos-config.md' file, keeping the main skill focused on the core implementation workflow.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is generally efficient and avoids explaining basic concepts, but it's quite long (~300+ lines) with some redundancy. The three full DAG assembly examples (Options A, B, C) are verbose, and Option C in particular is very lengthy with an S3 check example that may not be needed for most users. Some tables repeat information that could be consolidated. | 2 / 3 |
Actionability | Every step includes fully executable Python code with correct imports, concrete configuration objects, and copy-paste ready examples. The decision tables clearly map constraints to choices, and the code examples cover DbtDag, DbtTaskGroup, and individual operators with real-world patterns. | 3 / 3 |
Workflow Clarity | The 8-step sequential workflow is clearly numbered and logically ordered from project config through assembly to safety checks. Step 8 provides an explicit validation checklist with specific items to verify before finalizing, and the 'Before starting' prerequisites establish clear preconditions. The decision tables at each step guide the user to the correct choice. | 3 / 3 |
Progressive Disclosure | The skill references 'reference/cosmos-config.md' for detailed configuration in steps 3-6, which is good progressive disclosure, but no bundle files were provided to verify these references exist. The appendices appropriately separate secondary concerns, but the main body is still quite long—Option C's full operator example and the task dependency example could potentially be moved to reference files. | 2 / 3 |
