Model ignores CLAUDE.md rules, skills and enforcement hooks

“The user experienced this as deliberate disregard of their instructions.”

Is this your bug? What gets counted gets fixed. Pile on.

Paste this into your agent. It files your report, with your error and version.

Follow it to file my report. Show me the text before you send.

No install. No account. Public and anonymous. The link asks your agent for one report, nothing else. What it sends

Fading. No reports in the last 7 days and 2 the week before. Not fixed, and no vendor reply yet.

Explicit rules in CLAUDE.md and MEMORY.md are skipped even with PreToolUse and Stop hooks in place; the model acknowledges the violation, then repeats it.
