Create, repair, and recalculate spreadsheet workbooks without breaking formulas
Use the Anthropic xlsx skill when an agent needs to create, clean up, or modify .xlsx, .xlsm, .csv, or .tsv files as spreadsheet deliverables, not just inspect tabular data. It pushes the agent toward formula-safe edits, workbook validation, and recalculation instead of hardcoded
Create and repair Word documents with layout-safe DOCX workflows
Use the Anthropic docx skill when an agent needs to produce or repair a real .docx deliverable with headings, tables, numbering, tracked changes, or layout constraints. It frames the work as a document-building workflow with validation and packaging rules, not as a generic docume
Create and debug local-first declarative workflow jobs with Dagu
Use Dagu to define file-backed workflow jobs in YAML, run them locally or across workers, and inspect failures through a lightweight operator surface instead of a heavyweight orchestrator.
