Feature Flag Strategy
Design and manage feature flag lifecycles for safe, gradual rollouts
Best use case
Feature Flag Strategy is best used when you need a repeatable AI agent workflow instead of a one-off prompt.
Design and manage feature flag lifecycles for safe, gradual rollouts
Teams using Feature Flag Strategy should expect a more consistent output, faster repeated execution, less prompt rewriting.
When to use this skill
- You want a reusable workflow that can be run more than once with consistent structure.
When not to use this skill
- You only need a quick one-off answer and do not need a reusable workflow.
- You cannot install or maintain the underlying files, dependencies, or repository context.

# Feature Flag Strategy Skill Design and manage feature flag lifecycles for safe, gradual rollouts. ## Trigger Conditions - New feature flag is created - Existing flag is older than 90 days - User invokes with "feature flag strategy" or "rollout plan" ## Input Contract - **Required:** Feature being flagged - **Required:** Rollout target and timeline - **Optional:** Risk assessment, rollback criteria ## Output Contract - Flag configuration with rollout stages - Monitoring criteria for each stage - Cleanup plan with ticket and deadline - A/B test configuration (if applicable) ## Tool Permissions - **Read:** Flag configs, feature code, monitoring dashboards - **Write:** Flag configurations, cleanup tickets - **Search:** Codebase for flag usage ## Execution Steps 1. Define the flag with name, owner, and expiration date 2. Design rollout stages (internal → canary 1% → 10% → 50% → 100%) 3. Define monitoring criteria and auto-halt thresholds 4. Configure flag evaluation (centralized, not scattered if/else) 5. Create cleanup ticket with 90-day deadline 6. Document in flag inventory ## Success Criteria - Flag has owner, expiration, and cleanup ticket - Rollout stages defined with monitoring criteria - Auto-halt configured for error rate/latency anomalies - Both flag-on and flag-off paths tested ## Escalation Rules - Escalate if flag has been active >90 days without cleanup - Escalate if rollout shows >5% error rate increase - Escalate if flag cleanup has cross-team dependencies ## Example Invocations **Input:** "Create a feature flag strategy for the new checkout flow" **Output:** Flag: ENABLE_NEW_CHECKOUT, owner: payments-team, expiration: 2026-05-01. Rollout: internal (week 1) → 5% canary (week 2, monitor error rate/conversion) → 25% (week 3) → 100% (week 4). Auto-halt: >2% error rate increase or >10% conversion drop. Cleanup PR template created.
