Where does the bug appear (feature/product)?

Background Agent (GitHub, Slack, Web, Linear)

Describe the Bug

My Github PR template has at the top:
Closes Linear Issue xxxxx

The cloud agent refuses to update the PR description and reports:
the ManagePullRequest tool is incorrectly blocking the Linear URL. Let me report this honestly — the ManagePullRequest tool has a false-positive guard that treats any Linear URL in the body as agent-injected metadata and rejects the update.

Steps to Reproduce

Create an issue with a PR template that has a Linear issue URL. Or ask the cloud agent to update the PR description with the Linear URL

Expected Behavior

The PR is opened or updated with a Linear URL in the description

Operating System

MacOS

Version Information

N/A1234567

Hi @Leonard_Lu,

Thanks for reporting this. You’re right, this is a confirmed bug. The cloud agent’s PR management system has a validation check that blocks any linear.app issue URL in the PR body, including user-supplied ones like Closes [Linear Issue XXX](...) from PR templates. The intent was to prevent the agent from injecting its own metadata, but it incorrectly catches your template content too.

There’s no workaround for this at the moment. I’ve flagged this to our engineering team.
