Analyze and improve performance, throughput, latency, and concurrency behavior in Kotlin plus Spring services using real evidence from metrics, traces, SQL, thread or heap signals, and code paths.

Translate between Excel (.xlsx) files and Markdown with high-fidelity round-trip. Use this skill whenever the user wants to convert a spreadsheet to Markdown, review or diff a workbook as text, edit cell values or formulas in Markdown and regenerate the .xlsx, or keep a canonical text version of a workbook alongside the .xlsx. Triggers: 'xlsx to markdown', 'excel to md', 'convert this workbook to markdown', 'edit this spreadsheet as text', 'rebuild this xlsx from markdown', 'export spreadsheet as markdown tables', 'round-trip my excel file'. Preserves sheets, formulas, merged cells, number formats, fills, fonts, column widths, freeze panes, named ranges, data validations, and charts via a sidecar meta.json. Not a replacement for the base xlsx skill when building a complex financial model from scratch — use that skill for new models, and use this one for round-trip translation.
