What problem does it solve? AI responses often lack the depth of senior-level engineering judgment, skipping tradeoff analysis, root-cause investigation, and scale considerations. This Skill supplies five structured prompt modes that force deep analysis before action, elevating output quality for building, reviewing, debugging, and architecting software. ## Core Features & Use Cases - Five Thinking Modes: Full-Stack Builder, Codebase Auditor, Production Debugger, Technical Architect, and Performance Engineer, each with a ready-to-use structured prompt. - Skill Injection: Modes can be injected into other skills (e.g., architecture planning, code review) to add senior-level rigor to existing workflows. - Mode Chaining: Combine modes for complex tasks, such as Architect to plan, Builder to implement, Performance Engineer to optimize, and Auditor to review. - Use Case: When debugging a production incident, apply the Production Debugger mode to trace execution paths, identify the true root cause rather than symptoms, and produce tested fixes with regression coverage. ## Quick Start Ask the agent to act as a senior engineer and review this codebase using the Codebase Auditor mode to identify architecture issues and propose a phased refactoring plan.
