What is Pattern Learning?
Last updated: 2025-04-11
Why does pattern learning matter for engineering teams?
Every codebase has conventions that aren't written down: 'we always use guard clauses,' 'this service never makes external calls directly,' 'error handling goes through the middleware.' Generic review tools flag these as issues because they don't know the codebase's rules. Pattern learning turns the codebase's own history into a custom rule set.
How does Argus handle pattern learning?
Argus indexes every review finding as a pattern with its context — the files involved, the severity, whether it was dismissed or accepted, and the reasoning. Over time, these patterns form a codebase-specific knowledge base that informs future reviews. Accepted patterns become enforced rules; dismissed patterns become suppression signals.
Pattern learning reduces false positive rates by 58% after 50 reviews as the system adapts to codebase conventions — Argus internal benchmark, 2025
