Stale Feature-Flag Sunset Scanner with Auto Removal PR
Runs nightly to find feature flags whose sunset date has passed, then opens a GitHub PR that deletes the flag's code branches and config entry so dead flags don't pile up.
How it runs
The automated pipeline, trigger to output.
- TriggerNightly schedule fires
- ActionRead flag registry from PostgresPostgres
- LogicKeep flags past sunset date
- ActionOpen removal PR per stale flagGitHub
- OutputPost new PR list to SlackSlack
What it does
Scans your feature-flag registry every night, finds any flag whose sunset date is in the past, and opens a focused GitHub pull request that strips the flag from both code and config. Each stale flag becomes one reviewable PR instead of a backlog item nobody touches.
When to use it
Use it when your team adds flags faster than it removes them and 'temporary' flags have started living for months. Best for orgs that already record a sunset or expiry date alongside each flag.
How it works
- 1A nightly schedule fires the run.
- 2The flag registry table in Postgres is read and each flag's sunset date is compared to today.
- 3A logic step keeps only flags whose sunset date has already passed.
- 4For each stale flag, GitHub is searched for every reference, the conditional branches are collapsed to the shipped path, and the config entry is removed.
- 5A pull request is opened per flag with the diff, the original sunset date, and a removal checklist.
- 6A Slack message posts the list of new removal PRs to the platform channel.
