What problem does it solve?
It helps you make better architecture, refactoring, and algorithm decisions for non-trivial engineering work, improving clarity, correctness, and maintainability without unnecessary complexity.
Core Features & Use Cases
- Single Responsibility, tuned to the right granularity: Keeps cohesion high while avoiding both over-fragmentation and premature DRY.
- Algorithmic complexity reasoning: Guides when to analyze time/space complexity and which techniques typically meet the target complexity.
- Senior engineering mindset and guardrails: Improves naming, boundary validation, testability (when tests exist), and comment discipline.
- Self-review checklist before presenting code: Verifies purpose, acceptable performance, edge cases, readability, and duplication tradeoffs.
Quick Start
Apply senior-dev-principles to the task “refactor this module and redesign the data flow to be more maintainable,” and produce a scoped plan plus the changes that follow these quality criteria.
