⚠️ Platform note — read before running any command. The shell snippets in this skill are written for macOS / Linux (bash/zsh). Always check which OS you are on first. On Windows do not run them verbatim — the underlying tool/CLI commands are usually cross-platform, but the surrounding shell syntax is not. Translate it to PowerShell before running:

bash (macOS / Linux)	PowerShell (Windows)
a && b	run as two steps, or a; if ($?) { b }
cat <<'EOF' | tool … (heredoc)	write the text to a temp file, then pipe/pass that file to the tool
VAR=$(cmd) … $VAR	$VAR = cmd … $VAR
cmd > /dev/null	cmd > $null
… | grep PAT	… | Select-String PAT
… | jq …	… | ConvertFrom-Json, then read the fields
python3 x.py	python x.py (or py x.py)
~/dir, /tmp	$env:USERPROFILE\dir, $env:TEMP
cp / mkdir -p / rm -rf	Copy-Item / New-Item -ItemType Directory -Force / Remove-Item -Recurse -Force

If a command has no obvious Windows equivalent, prefer the built-in file/HTTP tools over raw shell.

OfficeCLI Financial-Model Skill

This skill is a scene layer on top of officecli-xlsx. Every xlsx hard rule — shell quoting, incremental execution, Help-First Rule, visual delivery floor, CFO 4-color code (blue input / black formula / green cross-sheet / yellow-fill assumption), number-format standards (years as text, zero as -, % one decimal, negatives in parens), assumption-cell discipline, CSV batch import, chart data-feed forms (a/b/c), the 5-gate Delivery cycle, cache-drift guidance, Known Issues (the cross-sheet ! trap, batch + resident for formulas, renderer caveats) — is inherited, not re-taught. This file adds only what a financial model requires on top: three-zone architecture, 3 model-type recipes (3-statement / DCF / LBO), sensitivity + scenario protocols, financial-function patterns, circular-reference discipline, and model-specific Delivery Gates 4–6.
