Stop saying 'write code': 8 senior-engineer prompt templates for Claude

aitrendz_xyz · x · 2026-11-05

aitrendzxyz shared a set of structured prompt templates for Claude and other coding assistants, arguing that vague instructions like "write code" or "fix this error" produce bad output, and that role-plus-deliverable prompts get senior-engineer-quality results. Seven templates shown in the thread:

Understand and refactor a codebase: model acts as a new senior hire — map architecture and data flow, flag structural problems, duplication and bottlenecks, then propose a refactor plan.
Senior debugging engineer: step-by-step root-cause analysis of a production bug, with edge cases and production-ready fixes.
Design and build a system: scalable architecture, component structure, data flow, API design, DB schema, caching strategy, plus a minimal production implementation.
Performance tuning: find bottlenecks and inefficient logic, list issues with fixes and improved code.
Rebuild it clean: behavior-preserving refactor with better modularity, lower coupling, and a new folder layout.
Multi-agent workflow: one prompt orchestrating Architect, Engineer, Reviewer and Optimizer roles, showing each stage's output.
Production-ready UI components: accessible, responsive components covering loading states and edge cases, with architecture, props design and usage examples.
