Fetching PR Summary

I'll fetch and summarize PR mattermost/mattermost-mobile#9405 as requested.

Todo List:

• Fetch PR details from GitHub API - Unable to access external GitHub API due to tool restrictions
• Explain limitation and provide alternatives

Limitation

I'm unable to fetch information from external GitHub repositories (mattermost/mattermost-mobile) due to current tool restrictions. The curl command to access the GitHub API requires approval that I don't have in this context.

Alternative Approaches

To get information about mattermost/mattermost-mobile#9405, you could:

1. Direct link: Visit the PR directly at [MM-66591] Channel Summaries with Agents mattermost-mobile#9405
2. Use gh CLI: If you have GitHub CLI installed locally, you can run:

   gh pr view 9405 --repo mattermost/mattermost-mobile

3. Request expanded permissions: The PR review comments in this current PR suggest adding curl permissions to the Claude action configuration, which would enable this functionality in future runs.

Context from Current PR

Interestingly, this current PR (#8648) includes discussions about expanding Claude's allowed tools to include curl commands for GitHub API access, which would resolve this exact limitation for future requests.

@jwilander @nickmisasi @crspeller - What's the next step for this PR?

[crspeller]

@cwarnermm Well it looks like the permissions idea didn't work so I think maybe we just strip this back to the update and merge.

Unless @nickmisasi you want to try something else? Personally I think this use case is likely better served locally anyway. Or at least by something like claude code web.
