Quick Review

The skill provides a basic ETL workflow for loading CSV/XLSX files into DuckDB with validation reporting. However, the description lacks critical details: where to place input files, how to specify them, what validation rules are applied, and what the '以묐떒' table contains. A CLI agent would struggle to invoke this skill without knowing input file locations or parameters. The task knowledge is minimal in SKILL.md (references run.ps1 which presumably contains the logic). Structure is acceptable for a simple skill but could benefit from explicit parameter documentation. Novelty is moderate—while ETL + DuckDB integration has value, the skill appears relatively straightforward for a CLI agent with access to DuckDB libraries. The fail-safe mechanism and evidence requirements are good additions but don't compensate for the lack of invocation clarity.
