claude-code - 💡(How to fix) Fix False positive: Usage Policy block on technical markdown integration task

What happened

In the middle of a long-running Claude Code session on a personal project, a routine user message was blocked with:

API Error: Claude Code is unable to respond to this request, which appears to violate our Usage Policy (https://www.anthropic.com/legal/aup). Try rephrasing the request or attempting a different approach.

Request ID: req_011CbJsgRw9q1h9LjMxgjbnY

Context

The session was integrating section drafts into a markdown investigation report — a technical document about per-file-type extraction mechanism selection for email attachments. Nothing in the conversation has plausible policy relevance (no security/abuse/ sensitive-content angle; ordinary software-engineering work on a single-user productivity tool).

The blocked turn was a normal continuation of that work — answers to a prior AskUserQuestion plus a request to proceed. Retrying was not attempted before filing this; reporting now while the Request ID is fresh.

Expected behavior

Request handled normally — no Usage Policy intercept on technical markdown editing tasks.

Actual behavior

Hard block returned to the client; user had to interrupt the in-progress workflow to investigate.

Repro

Not deterministically reproducible from the user side — the classifier signal isn't visible. Including the Request ID so the upstream decision can be inspected.

Environment

• Claude Code in VS Code extension
• Long session with a large working file (~2,500-line markdown document) loaded in context
• Model: Opus 4.7 (1M context)
