Open-Sourced Claude Code Planning Skill Updated

sujingshen · x · 2026-07-19

The author has packaged a "planning first" approach into an open-source Claude Code skill, emphasizing that saving 15 minutes on initial requirement definitions often leads to 3 hours of debugging later. This update includes a four-language README, core architecture principles, validation gates for each version, and a "documentation as runtime" design philosophy. The goal is to embed planning, constraints, and validation directly into the coding workflow.
