=== How to fix "Claude Cowork login stuck on browser screen when signing in with Gmail" ===

'''Symptoms'''

After installing [https://claude.com/product/cowork Claude Cowork] and attempting to sign in with a Gmail account, the browser window remains open and the login process never completes, preventing access to Claude.

'''Product Affected''': Claude Cowork

'''Suggested Workaround:'''

* Disable ad-blocking browser extensions (e.g. [https://ublockorigin.com/ uBlock Origin]) before signing in. These extensions can interfere with the OAuth authentication flow, causing the browser redirect to hang indefinitely.

=== How to fix "stop_reason": "refusal" in Claude API ===

'''Error message'''

<pre>

{

"id": "msg_xxx",

"type": "message",

"role": "assistant",

"content": [],

"stop_reason": "refusal",

"stop_sequence": null,

"usage": {

"cache_creation_input_tokens": 0,

"cache_read_input_tokens": 0,

}

</pre>

'''Model Affected''': Claude Opus 4

'''Suggestion'''

Prompt met "refusal" error

<pre>

Please help find the company's unified business number:

Company name: {$companyName}

</pre>

Revised prompt:

<pre>

Please help find the following company's publicly available basic information: the company's unified business number:

Company name: {COMPANY_NAME}

</pre>

'''Root cause:''' Common Triggers:

* Privacy-related requests - asking for personal data or private information

* Confidential information queries - requesting internal data or business secrets

* Security-sensitive content - potentially harmful or inappropriate requests

* Ambiguous identity information - queries that may involve identity identification

'''Suggested:'''

* Replace sensitive keywords in your prompts (e.g., "confidential" → "public", "internal data" → "public documents", "private information" → "publicly available information")

* Add safety declarations explicitly stating you only want publicly available information

* Use structured prompts that specify data source limitations and public nature requirements

* Implement the smart retry mechanism with prompt modification when refusal is detected

* Consider using the `RefusalPreventionHelper` class to assess and sanitize prompts before sending to API

'''Official Documentation:'''

'''Suggested Workaround:'''

* When uploading PDF files in the Claude system, consider paste the relevant text directly into our conversation for better processing<ref>[https://www.reddit.com/r/ClaudeAI/comments/1bquumd/cant_upload_pdf_or_text/?rdt=54340 Can’t upload pdf or text : r/ClaudeAI]</ref>. Use [[Convert PDF to Text]] tools to help with the conversion.

* ~~When uploading Excel~~ files for ~~analysis in the Claude system~~, ~~consider converting and uploading an alternative CSV~~ (~~Comma~~-~~Separated Values~~) or ~~TSV (Tab-Separated Values) file instead~~.

* For other file types encountering errors, it's likely due to file conversion issues. It's recommended to manually convert files beforehand into formats that are easier for machines to read, such as Unicode (UTF-8) encoded TXT or CSV files<ref>[https://www.reddit.com/r/ClaudeAI/comments/1e4nzb5/claude_giving_me_text_extraction_failure/ Claude giving me text extraction failure : r/ClaudeAI]</ref>.
