5 Claude Code skills I use every single day

A workflow-focused breakdown of 5 Claude Code 'skills' (custom prompt instructions) used daily to improve AI-assisted development. The five skills are: 'Grill Me' (forces the LLM to interview you exhaustively before planning), 'Write a PRD' (turns a shared understanding into a structured product requirements document submitted as a GitHub issue), 'PRD to Issues' (breaks a PRD into vertical-slice GitHub issues with blocking relationships), 'TDD' (enforces red-green-refactor loops with interface-first thinking), and 'Improve Codebase Architecture' (identifies shallow modules and spawns parallel sub-agents to propose interface redesigns). The author argues that well-structured processes and clean codebases are the primary levers for improving AI code quality, and that treating agents like stateless humans with strict workflows is the key insight. A paid cohort course is also promoted throughout.
