huashu-excel: Adding a Reconciliation Gate for AI Excel Analysis

huashu-excel is a data analysis and Excel full-process skill maintained by alchaincyf, and is also a plugin for DeepSeek Harness. It employs an eight-step process (health check, cleaning, alignment, analysis, reconciliation, delivery, verification, quality control) to address the issue where AI makes calculation errors without raising alerts during data analysis. Specifically, it inspects raw cells before manipulating pandas, treats the total row within the table as a checksum, runs a master check before delivery, and halts delivery if mismatches are found. It is accompanied by eight independent scripts and a set of chart honesty constraints, relies solely on openpyxl, and is universally applicable across agents. The article provides DSH installation commands, script commands, and the applicable scope.
