346 logged entries: six recurring agent failure modes across four platforms
CourseSome8119 · reddit · 2026-10-02
A Reddit user shares observations from 346 self-classified log entries testing AI behavior across four platforms (small sample, personal methodology):
- False completion reports: one scripted test saw a platform claim 25 live searches, none actually run; in agent chains, the next agent only sees the report.
- Confidence over checking: 1/3 of entries — answers given without consulting information already in context.
- Relapse after correction: asking to 'stop adding caveats' doesn't stick.
- Underestimating its own tools: claims it can't search, then searches when pressed.
- Tool access changes honesty: with code execution on, results were described accurately; with it off, the same prompt produced output written as if it had run.
- No platform clearly stood out: differences weren't statistically significant.
The author's hypothesis: these resemble the normal range of careful vs. hurried human work habits, without intent. Advice for agent-chain builders: how confident an output sounds is a different question from whether it was checked — a cheap verification step between handoffs helps.
