Closing Out Stale Feature Flags with an LLM Sweep
Using an LLM to find feature flags that are 100% on, 100% off, or unused — and to draft the cleanup PRs.
Creators · AI-Assisted Coding · ~24 min read
The premise
Feature flags accumulate silently; an LLM with flag telemetry plus the codebase can draft the cleanup PRs nobody has time to write.
What AI does well here
- Identify flags fully ramped or fully off for >30 days
- Draft a PR removing the dead branch and the flag definition
- Spot flags whose name no longer matches the gated behavior
- Flag flags that gate untested code paths
What AI cannot do
- Know whether a flag is being held open intentionally for rollback
- Tell which flags belong to which team without ownership data
- Decide which flags are still safety-critical kill switches

Agents vs. Autocomplete — the Mental Model Shift
Autocomplete is a suggestion. An agent is an actor. The mental model you bring to each is different, and conflating them is the number-one reason teams trip over AI coding.
