feature-flags

name	feature-flags
description	Use feature flags safely: match the flag type to its purpose (release/experiment/ops/permission), give every risky change a kill switch, roll out progressively gated by a health signal, evaluate deterministically and fail-safe, and manage the flag lifecycle to prevent debt.

Feature Flags

Type by purpose

Type	Lifespan
Release	temporary (remove after launch)
Experiment	until decision
Ops (kill switch)	long-lived
Permission/entitlement	permanent

Treating all flags the same grows debt.

Safe rollout

Kill switch for every risky change (off without a deploy). Progressive 1% -> 10% -> 100% gated by a health signal (with devops-cicd/observability-sre).

Evaluate + lifecycle

Deterministic + sticky; fail-safe defaults when the service is unreachable. Every temp flag: owner + removal date. Stale flags = combinatorial config debt + incidents.
