Environment
- Platform: Claude Code CLI WebFetch
- Claude CLI version: 1.0.61 (Claude Code)
- Operating System: Linux 6.12.10-76061203-generic
- Terminal: gnome-terminal-server
Description
WebFetch tool cannot retrieve actual content from Atlassian Confluence wiki pages, instead returning compiled CSS stylesheets and JavaScript configuration files.
Steps to Reproduce
- Use WebFetch on any Shibboleth Confluence URL
- Example: https://shibboleth.atlassian.net/wiki/spaces/IDPPLUGINS/pages/3395321933/WebAuthnAuthnConfiguration
- Tool returns CSS/JS assets instead of HTML page content
Expected Behavior
Should return HTML page content with documentation text
Actual Behavior
Returns large CSS stylesheets and JavaScript build configuration
Evidence:
- Multiple URLs tested, all return same CSS/JS content
- WebFetch works correctly on other sites (e.g., httpbin.org)
- WebSearch can find the Confluence pages, but WebFetch cannot access their content
- No HTML tags (\<html>, \<head>, \<body>) found in responses
Impact:
Cannot access technical documentation needed for development tasks
Suggested Root Causes:
- JavaScript-heavy content rendering
