Feature Flagging Skill
Overview
Specialized skill for feature flag configuration and rollout planning. Enables product teams to plan and manage controlled feature releases with proper targeting, monitoring, and rollback strategies.
Capabilities
Flag Design
- •Generate feature flag specifications
- •Design flag naming conventions
- •Create flag documentation templates
- •Define flag types (release, experiment, ops, permission)
- •Plan flag dependencies and interactions
Rollout Planning
- •Design rollout percentage strategies
- •Create flag targeting rules
- •Plan canary and gradual rollouts
- •Define geographic or segment-based rollouts
- •Create rollout schedules
Operations
- •Generate kill switch procedures
- •Track flag lifecycle and cleanup
- •Monitor flag impact on metrics
- •Plan flag deprecation
- •Create incident response procedures
Target Processes
This skill integrates with the following processes:
- •
product-launch-gtm.js- Feature flag rollout for launches - •
beta-program.js- Beta feature flagging - •
conversion-funnel-analysis.js- A/B test flag management
