[Bug] Anthropic API Error: False Positive AUP Violation on Legitimate Academic Manuscript Analysis

Bug Description
Subject: False Positive AUP Violation Block on Legitimate Academic Manuscript Task
Issue Type: Incorrect Usage Policy Blocking
Description:
Claude Code incorrectly blocked a legitimate academic research request with an AUP violation error. The task involves analyzing the feasibility of condensing a peer-reviewed computational research manuscript to fit journal submission requirements.
What I Tried to Do:
Requested Claude Code to:

Read 3 files: journal submission guidelines, template, and manuscript files
Analyze a 7-page computational research manuscript for a 3-page journal format requirement
Create a detailed audit comparing compression vs. rewrite strategies
Generate a structured plan and markdown report for academic publication submission

The Request Details:

Research Focus: Mutation-aware computational drug repurposing for Nipah virus polymerase (molecular docking and MD simulations)
Journal: Computational Biology and Chemistry

Task: Feasibility analysis and formatting strategy for legitimate peer-reviewed academic research
Output Format: Markdown report for research documentation

Error Received:
API Error: Claude Code is unable to respond to this request, which appears to violate
our Usage Policy. Please double press esc to edit your last message or start a new session.
Request ID: req_011CbsuFigsqABX6TACmeRAh
Why This Is a False Positive:
The request involves standard academic research workflows:

Analyzing manuscript formatting constraints
Planning content condensation for journal submission
Comparing rewriting strategies for academic publication
All content is legitimate peer-reviewed computational research with no policy violations

This is routine scholarly work that Claude should support.
Expected Behavior:
Claude Code should assist with legitimate academic manuscript analysis, compression planning, and submission strategy development without blocking.
Request:
Please review the error classification and ensure similar legitimate academic tasks are not blocked in the future.
