Why Agents Always Get Stuck in the Last Mile
Individual-Court-217 · reddit · 2026-07-18
After testing task-completing agents on real websites, the author found that "finding the right page" is rarely the bottleneck; the real hurdle is the last mile.
Primary failure modes include:
- Bizarre form validations causing sudden mid-process failures
- Pop-ups stealing focus and unexpected login walls
- Inconsistent outcomes where the same flow succeeds sometimes and fails randomly at others
- Unreliable agent logs that frequently claim "done" before an action is actually submitted successfully
The author is looking to crowdsource common stability breaking points on real sites, logins, and multi-step flows, and to find out which solutions actually hold up.
