Free. No signup beyond the download.Five failure patterns from one unattended pipeline, with the fix for each. Four of the five are the tool lying about the work, not the work failing: The hardcoded date in the verification step - publishing worked perfectly; the check was broken. The cleanup crash that eats the whole job - 43 of 45 files produced, then EPERM on the temp folder. All 43 thrown away. The fetch with no timeout - a hung gate is worse than a failed one. A failure alerts you; a hang just stops. The stale artifact that passes every check - right name, right size, from yesterday. A dead pipeline reports green for a week. The zero-byte artifact - ffmpeg exits 0 having written a 0-byte mp4. Includes a runnable demo. node demo/try-it.mjs builds three fake pipelines and shows you which verdicts an exit code gets wrong. Two seconds, no dependencies, nothing installed.The meta-lesson: a pipeline that cries wolf trains you to ignore it, and the day it is finally telling the truth, you ignore that too. False failures are as dangerous as silent ones - they are just slower.Verify artifacts, not exit codes.Want the tool that checks all of this against your real build? ProveDone is $19, and ProveDone Team at $149 adds a dashboard for every gate, Slack/Discord alerts, and a GitHub Action. 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.
