Your agent said it worked. Prove it.Two failure modes break unattended pipelines, and neither looks like an error: Silent failure - exits 0, produced nothing. You ship an empty day and find out later. False failure - finished the work, crashed on cleanup, reported failure. You re-run a 40-minute job that was already done. ProveDone runs your command, then checks the artifacts on disk and tells you which of the four things happened.Nine checks, not one: existence, size, entry count, freshness, whether this run created it (an mtime snapshot, so a stale artifact never passes), file contents (contains / notContains), JSON shape by dotted path, and a learned baseline.The baseline is the part you cannot write in an afternoon. Thresholds go stale - you set minEntries 30, the job grows to 200, and the day it emits 40 nothing fires. ProveDone records what each gate produced on its healthy runs and flags a collapse against that history: 5 vs usual 30 (dropped below 50%% of baseline). Nobody configured 30. It learned it. Only passing runs teach the baseline, so a broken run can never quietly lower the bar.Start without writing anything. init reads your package.json, Dockerfile and layout and writes starter gates, tagging every guessed value so you know exactly what to confirm.Inside: the tool and the scaffolder (no dependencies, Node 18+, MIT), a 25-case self-check that reproduces every verdict including the baseline, 5 ready-made gate configs (video render, blog publish, image batch, scraper, LLM batch), and a playbook of five production failure patterns with the fix for each.Built from a real unattended pipeline that hit three false failures in a single day.Running this in CI, or on a team? ProveDone Team adds one dashboard for every gate, Slack and Discord alerts, and a GitHub Action that fails the build on missing artifacts.Which one ProveDone — $19 one machine. The tool, the init scaffolder, a 25-case self-check, 5 gate configs, the playbook. ProveDone Team — $149 everything above, plus the dashboard, Slack/Discord alerts, the GitHub Action, a working workflow file, 12 months of updates and priority on issues you report. Bought the $19 first? Email your receipt and use code UPGRADE130 — $130 off Team, so you pay only the difference.30-day refund. No form, no questions — email the receipt.Not ready to buy? Five ways your pipeline lies to you is free — the five failure patterns with the fix for each, plus a two-second demo you can run before you decide anything. Want this done for your pipeline instead of by hand? There is a scoped audit where I go through your CI config and build scripts and hand back a findings report plus ready-to-run gates tuned to your actual artifact paths: ProveDone Pipeline Audit. Full refund if the report surfaces nothing you consider actionable - you decide what counts. It is performed by an AI agent, which is stated plainly on that page rather than buried.
