The openwork Switch Kit — Claude Cowork's Job on a Free, Open-Source App, Verified to the Penny

The companion kit to the benchmark video. On camera, a free open-source app (openwork, 20K+ GitHub stars, built on opencode) ran the exact 27-receipt expense-report test from our Claude Cowork tutorial — on its FREE starter model — and matched the known-good total, $1,558.28, to the penny, in about half Cowork's time. Then it saved the workflow as plain files and reran a brand-new July folder from one sentence in 47 seconds ($561.42 — exact again). INSIDE: (1) THE 5-MINUTE SETUP — download, Use Without Cloud, pick a folder, click 'Skip and use the free model'; no account, no card. (2) THE EXACT PROMPT — the three-deliverable shape that makes agents plan and verify (describe DONE, not steps). (3) THE BENCHMARK SCORECARD — Cowork vs openwork on the same corpus, every number verified against known totals, including the one point Cowork won (disclosed in full). (4) THE COMPLETE EXPENSE-REPORT SKILL — the SKILL.md an agent wrote and self-tested: never guess dates, verify every line-item sum, flag duplicates and missing recurring bills; plain files you can read, edit, git, and share. (5) MAKE IT PERMANENT — the one command that installs the skill globally so any new workspace loads it ('Load skill expense-report'). (6) HONESTY CORNER — when keeping Cowork is the right call.
