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
