Remote session fails with 'Claude GitHub app must be installed' despite app being installed

Description

Remote/background task execution fails with the error:

Cannot launch remote Claude Code session.

The Claude GitHub app must be installed on this repository first.
https://github.com/apps/claude/installations/new

However, the Claude GitHub app is installed and configured correctly.

Environment

• Claude Code CLI (latest)
• macOS (Darwin 25.3.0)
• Repository: private repo with SSH remote (git@github.com:owner/repo.git)

Configuration verified

1. Claude GitHub app installed 25+ minutes ago
2. Repository access set to "All repositories"
3. Permissions include:

• Read access to actions, checks, and metadata
• Read and write access to code, discussions, issues, pull requests, and workflows

1. Git remote correctly points to GitHub

Screenshot

App installation settings show:

• "All repositories" selected
• Installed 25 minutes prior to error

Expected behavior

Remote session should launch successfully since the app is installed with proper permissions.

Actual behavior

CLI reports the app is not installed despite it being configured correctly.
