About
Built on scar tissue.
Twenty years of watching production fail taught me something that no testing framework ever could: the bugs that destroy systems aren't the ones tests catch. They're the ones no one thought to look for. The assumptions hiding in plain sight.
Eric Cogen -- Founder, GauntletCI
Eric Cogen is a senior .NET engineer with twenty years in production. He has shipped payments systems, internal platforms, and critical line-of-business applications — the kind where a 2 a.m. alert wasn't an emergency, it was a regular Tuesday. GauntletCI is the pre-commit checklist he wishes he had run before every commit.
Why this matters
Tests verify the happy path
Green builds ship broken code constantly. Tests check what you expect to happen, not what might happen instead. They can't catch assumptions you didn't know you were making.
Code review doesn't scale
Humans reviewing diffs at scale see syntax, miss semantics. A renamed method that swapped behavior. A removed guard clause in line 42 of a 500-line diff. Fatigue is real. Attention breaks.
Machines see patterns humans miss
Deterministic rules don't get tired. Don't get distracted. Don't skip the boring checks at 11 p.m. on a Friday. They run every time. Every diff. No exceptions.

The full story
Want the real narrative? Twenty years of production disasters, every escalation call at midnight, each alert that didn't fire, the bugs that slipped through code review, the fixes that introduced regressions. This is the origin story—not the polished pitch, but the actual scars that demanded a solution. Every rule in GauntletCI came from something that broke. Read how.
