Effector Reliability Rules

Concise ruleset for writing correct and testable Effector code. Each rule has a short rationale and examples.

When to Apply

Use this skill when:

• Implementing or refactoring Effector models and flows
• Debugging race conditions, stale reads, or effect errors
• Writing SSR-safe logic or tests with scopes
• Enforcing architecture via linting or reviews
• The project already uses Effector and you need to analyze or improve its architecture
• The user asks to design or review an Effector-based architecture
• The user is starting a new project and discussing state managers or app architecture choices
