What problem does it solve? Expense review fails silently when receipts are misread, totals are taken from the wrong line, or policies are applied from memory instead of stated rules. This Skill turns a batch of receipts into a line-by-line audit where every policy flag cites the receipt, the exact value read, and the named rule it trips. ## Core Features & Use Cases - Per-line receipt reading: Records merchant, date, total, and category from each receipt itself, quarantining unreadable receipts instead of guessing. - Cited policy flags: Every flag names the receipt id, the offending value, and the specific rule and limit it violates; unverifiable hunches are demoted to notes. - Cross-checks and diffs: Recomputes batch totals against claimed totals and diffs flags against the prior run's audit. - Use Case: Before submitting a trip's expense report, run the audit to get a dated markdown file with a line table, flag list, recomputed totals, and the single flag most needing the approver's attention. ## Quick Start Audit this batch of receipts against our travel policy and produce a line-by-line report with a cited flag on every violation.
