Co vs InterviewWatch

Every AI coding agent signs its commits with a forgeable plain-text line.

About Co

Every AI coding agent signs its commits with a forgeable plain-text line. Co-authored-by is a Lie: Cryptographic Provenance for AI Coding Agents . It matters now, because the attribution metadata is starting to be used to make trust decisions, and that turns a cosmetic line into an attack surface. Commit metadata has always been trivial to fake unless signing is enforced. So over a couple of evenings I built the missing half: a producer-attribution layer where attribution is backed by a hardware key, enforced automatically, and verifiable .

About InterviewWatch

The InterviewWatch agent flags AI assistance, hidden overlays, extra displays and remote control during a live interview, then signs a tamper-evident report. An agent runs on the candidate's machine during the interview and flags AI assistants, hidden overlays, remote control and virtual devices as they appear. Why it matters Interview cheating stopped being an edge case. If your interviews aren't monitored, you may already be extending offers on answers that were never the candidate's. Across 19,368 technical interviews, 38.5% of candidates were flagged for AI-assisted cheating, and the rate climbed from 9% to 45% in a single quarter.
