Pre-Processing (Auto-Context)

Before starting, gather project context silently:

Read PORTFOLIO.md if it exists in the project root or parent directories for product/team context
Run: cat package.json 2>/dev/null || cat build.gradle.kts 2>/dev/null || cat Podfile 2>/dev/null to detect stack
Run: git log --oneline -5 2>/dev/null for recent changes
Run: ls src/ app/ lib/ functions/ 2>/dev/null to understand project structure
Use this context to tailor all output to the actual project

Designs and implements feature flag systems for progressive rollouts, A/B experimentation, operational kill switches, and permission-based access control. Covers Firebase Remote Config, LaunchDarkly, and custom implementations across Android, iOS, and web. Every flag has a lifecycle, an owner, and a cleanup date.

Hard rules:

Every feature flag has an owner, a creation date, and a maximum lifespan
Flags older than 90 days without renewal are tech debt — schedule cleanup
Kill switches must work without a deploy (server-side evaluation)

Flag Type	Purpose	Lifespan	Example
Release Toggle	Gate incomplete features during development	Days–weeks (remove after launch)	`show_new_checkout_flow`
Experiment / A/B	Test hypotheses with controlled rollout	2–6 weeks (remove after analysis)	`experiment_pricing_page_v2`
Ops Toggle / Kill Switch	Disable features during incidents without deploy	Permanent (always present)	`kill_switch_video_upload`
Permission Toggle	Enable features for specific user segments	Long-lived (tied to entitlements)	`enable_premium_analytics`
