name: cross-project-changes description: Guidance for applying changes across multiple projects. Use when user wants to make changes across multiple projects or apps simultaneously.

Cross-Project Changes

Follow these steps when applying changes across multiple projects.

Step 1: Identify Target Projects

Determine which projects need the change:

• "all my projects", "all my apps", "all projects" or "all apps" means all folders in ~/code/own/
• If unsure, ask the user to specify the target projects
• Projects might be nested subfolders under ~/code/own/, not only direct children
• When searching for files across projects using ripgrep, use **/ globs to handle nested app roots (e.g., **/find/this/file.rb)

Step 2: Determine the Changes

Identify what changes to apply:

• Check if the user described the changes in their prompt
• If they mentioned "changes from the last commit" or similar, inspect the last git commit in the current folder

Step 3: Apply Changes to Each Project

Process each project individually:

• The implementation may differ between projects based on their structure
• If changes cannot be applied to a project, skip it and continue with the others
• Track which projects succeeded and which were skipped

Step 4: Run Relevant Tests

For each project where changes were applied:

• Identify tests related to the modified code
• Run those tests to verify the changes work correctly
• Note any projects that lack test coverage for the changes

Step 5: Report Results

After completing all projects:

• Summarize which projects were updated successfully
• List any projects that were skipped and why
• Mention any projects missing test coverage for the changes
• Do NOT commit changes to git unless explicitly requested
• Remind the user that changes have not been committed yet
