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.

Treating all flags the same grows debt.
Kill switch for every risky change (off without a deploy). Progressive 1% -> 10% -> 100% gated by a health signal (with devops-cicd/observability-sre).
Deterministic + sticky; fail-safe defaults when the service is unreachable. Every temp flag: owner + removal date. Stale flags = combinatorial config debt + incidents.
npx claudepluginhub mcorbett51090/ravenclaude --plugin experimentation-growth-engineeringGuides completion of development work by verifying tests, detecting environment, and presenting structured options for merge, PR, or cleanup.
Enforces test-driven development: write failing test first, then minimal code to pass. Use when implementing features or bugfixes.
