Reddit thread collects coding agents' most confidently wrong claims: 'all tests pass' tops the list
aldi949 · reddit · 2026-09-25
A Reddit discussion asks which confidently wrong statements coding agents (Cursor / Claude Code / Codex) make most often — not obviously bad code, but unverified assertions delivered as fact.
Recurring examples cited:
- "All tests pass"
- "This is the root cause"
- "This function isn't used anywhere"
- "That change is already in the branch"
- "This API supports X"
The OP is collecting real cases — what the agent claimed, what was actually true, how much time was wasted — and which claims people now refuse to trust without manual verification, aiming to map the recurring failure patterns of unverified assertions.
