Got the same error.

Prompt:

`CLAUDE.md
PLAN.md

continue with the phase 3, encoder implementation, focusing on correctness and any obvious performance bottlenecks. but mostly just getting it working properly`

Was flagged as "potentially violating usage policy". Thread ID was 019c4f21-6f56-71e0-8d6a-1ca2a8c6441a.

To the best of my understanding nothing in the project it is working on related to cyber security in any way.
The prompt was also written not by me but by codex itself, for a subagent.
