[BUG] WebFetch can't access claude.ai/share links — no way to share context between Claude and Claude Code

What's Wrong?

if claude code is given a URL for a shared claude conversation as context, cloudflare blocks access.

Bash(curl -s -o /dev/null -w "HTTP Status: %{http_code}\nRedirect URL:
%{redirect_url}\nContent-Type: %{content_type}\n"
"https://claude.ai/share/CONVERSATIONID…)
⎿  HTTP Status: 403
Redirect URL:
Content-Type: text/html; charset=UTF-8

• The root cause is Cloudflare bot challenge (cf-mitigated: challenge)
• It blocks a natural workflow of planning in Claude then executing in Claude

Code

• A native integration or exemption for share links would be valuable

What Should Happen?

Claude code should be able to consume the shared conversation without an error.
