dr-drilldown

@datarails Updated 2026-09-22

Drill down on a cell in the Datarails Excel Add-in to see underlying detail — also the skill to use when the user asks to "explain the variance", "explain this number", "what's driving this", "what's behind this cell", or break a figure into its line items. In a live Excel context (add-in agent bridge available) DR formula cells drill through the add-in's own drill-down; with an .xlsx file (Claude Code) it resolves DR.GET formulas, reads hidden "dr control" filters, queries Datarails, and validates totals; with no workbook at all, the user can paste a DR.GET formula or give structured filters (no-file mode). Self-contained — discovers the client's financials table and fields on its own, no profile or setup step required.

Install

With your agent

Install OMGSkills skill "datarails/dr-claude-code-plugins-re:skills/drilldown" into this agent's normal skills directory: call the OMGSkills MCP get_install_plan tool for your agent and run the script it returns (it installs only the pinned commit and verifies SKILL.md), and stop if MCP or the pin is unavailable. Do not overwrite or change existing skills without asking me.

Manual command

git clone https://github.com/Datarails/dr-claude-code-plugins-re /tmp/dr-claude-code-plugins-re && ln -s /tmp/dr-claude-code-plugins-re/skills/drilldown ~/.claude/skills/dr-drilldown

From README

DR.GET Drill-Down Drill into any cell that contains Datarails data to see the underlying line-item detail. Works with: Cells containing a DR formula directly (DR.GET/DR.QTD/DR.YTD/DR.MTD/… — any DR function) Cells containing an Excel formula (SUM, +, -, etc.) whose precedents are DR formula cells Three paths. In a live Excel context (add-in agent bridge available — Claude for Excel / an open workbook with the add-in), drilling a DR formula cell goes through the add-in's own drill-down via the agent bridge (Step 0 below) — the add-in resolves filters, dates, and totals natively. (Excel context is about the bridge being present, not whether the workbook is connected.) The MCP/openpyxl workflow (Phases 0–5) is the file fallback for Claude Code with an .xlsx file and no bridge. And with no workbook at all, no-file mode (below) takes a pasted DR.GET formula, a plain-language description, or structured filters straight from chat.
