It first connects to GitHub and scans Android source files (.kt and .java) from the selected repository. Then it reads the code, finds possible feature flags, config keys and other related values.\n\nNext, it compares those code flags with Firebase Remote Config flags. This helps identify flags that still exist in Firebase but are no longer used in the app code.\n\nAfter comparison, the workflow creates a short summary report showing total flags found, active flags and unused Firebase flags that may be removed. Finally, the report is automatically sent to a Slack channel so the team can review cleanup candidates.\n\n## Setup steps\n\n**1.** Add your GitHub credential in n8n.\n**2.** Update Repository configuration with your GitHub owner, repository name and branch.\n**3.** Add your Slack credential and choose the channel for reports.\n**4.** Replace test Firebase flags with real Firebase Remote Config API credentials when ready.\n**5.** Set weekly schedule time in the Cron node if needed.\n**6.** Run once manually to test the workflow output.\n**7.** Enable the workflow for automatic weekly reporting."
