ingridleiria Skill

Takes raw files to an analysis-ready .dta that can be defended line by line. Covers import from csv, Excel and fixed width, the encode and destring decision, variable and value labels, Stata's numeric date representation, merge with reported match rates and a rule for every _merge value, joinby, append, reshape in both directions, duplicates and isid, missing value codes including extended missing, collapse against egen by group, xtset and panel structure checks including gaps and unbalanced panels, compress and saving with notes, and the rule that a raw file is never overwritten. Use this skill when someone is importing data into Stata, merging files, reshaping a panel, fixing identifiers that will not match, converting strings to numbers, handling missing value codes, building a panel dataset, or says the numbers changed after a merge, the observation count is wrong, or the data will not xtset. Trigger also on vague requests such as "get this into Stata", "my merge is dropping observations", or "why is my s

ingridleiria Skill

Builds and audits driver-based financial models in a spreadsheet, covering three-statement, operating, unit-economics, and runway models, with every assumption in a labelled input cell, one scenario switch that moves every output, a visible checks block, and a reconciliation cell that reads zero. Enforces the rule that no number exists anywhere except as a labelled input or a live formula, so any output traces back to its drivers in under two minutes. Use this skill whenever someone wants to build, extend, or check a financial model, budget, cash flow projection, runway model, unit economics, or business case in a spreadsheet, or says model this out, what does the profit and loss look like if, build me a scenario, check my model, how long is our runway, sanity check these numbers, or asks what happens to the plan when one assumption moves. Trigger for any spreadsheet whose purpose is projecting money over time.

ingridleiria Skill

The discipline for analysing someone else's spreadsheet without breaking it and without trusting it blindly. Read the structure before touching anything, audit columns and existing formulas, establish one ground truth figure, build every analysis cell as a live formula reading the raw sheet, compute complements by subtraction, close a visible reconciliation cell to zero, and spot-check before delivering. This is the foundation the other workbook skills assume rather than repeat. Use it whenever a workbook, CSV export, accounting extract, or data file arrives and the task is to analyse it, add tabs, check someone else's numbers, rebuild a sheet that broke, or answer a question from it, including vague requests like "can you just pull the total", "does this add up", or "have a look at this file".
