Skill Instructions

This skill ensures controlled experimentation.

Inputs / Outputs / Non-goals

• Inputs: feature requirements, settings defaults, UI + engine touchpoints.
• Outputs: flag definitions, guarded logic, observability notes, test updates.
• Non-goals: shipping unflagged behavior or changing public APIs silently.

What this skill helps accomplish

• Safe rollout of new functionality
• Reversible changes
• Debuggable behaviour

When to use this skill

• Introducing new gameplay features
• Running experiments or trials
• Refactoring risky logic

Feature flag rules

1. New features default to OFF
2. Flags must be declared centrally
3. UI and engine must respect flags
4. Expose state via data-* attributes

File anchors

• Flag defaults: src/config/settingsDefaults.js
• Settings UI: src/pages/settings.html

Rollout checklist

• Flag declared with default OFF and documented usage.
• Guard added in both UI and engine touchpoints.
• On/off coverage in tests where behavior changes.
• Observability via data-* attribute or equivalent.

Expected output

• Flag definitions
• Guarded logic
• Observability hooks
