Budget Tracker Design Skill

Budget trackers die two deaths: too granular (forty categories nobody can code a coffee receipt into — abandoned by February) or too vague (three buckets that hide every overrun until it's structural). The living tracker matches its grain to how spending actually arrives (statement lines, invoices), answers one question at a glance — "are we okay, and where not?" — handles irregular expenses honestly (the annual insurance bill is not a "shock"), and costs fifteen minutes a month, because the ritual's survivability is the design's real constraint.

What This Skill Produces

• The structure — categories at statement-grain (8–15, not 40), the month × category grid, budget column with its source
• The variance view — actual vs. budget with the month-and-YTD dual read, conditional signals at honest thresholds
• The irregulars ledger — annual/lumpy expenses spread as monthly accruals so they stop being surprises
• The ritual — the fifteen-minute monthly update, sourced from statements, calendared

Required Inputs

Ask for these if not provided:

• The scope — household, team, or project budget; and the currency of pain ("we get surprised" vs "we can't approve spend" vs "the money just goes")
• The spend sources — cards, invoices, payroll, reimbursements; categories must match how these report, or every update becomes archaeology
• The budget numbers — from where (last year +X%? A plan? First-time guesses marked as guesses to be re-based at month 3)?
• The irregulars — the annual/quarterly lumps (insurance, subscriptions (subscription-audit finds them), taxes, conferences) — listed, because the design accrues them
