A B2B product manager shares a practical AI workflow — PRD four-step method, Skill reuse, and Context/Harness engineering — that reduced requirement work from 34 to 15 person-days while maintaining quality, with detailed case studies, boundaries, and learning strategies.
The author explains how, after ten years of writing, they analyzed their own articles, extracted evolving stylistic patterns, and engineered a modular, reusable writing skill—/phodal-writer/—that can be repeatedly loaded by AI to produce consistently structured, paced, and judgment‑rich content.
SkillCraft, a new benchmark from Oxford and partner institutions, evaluates whether AI agents can autonomously combine basic tools into reusable skills, revealing that stronger models dramatically improve task success rates while slashing compute consumption by up to 80%, and exposing the limits of hierarchical skill nesting and cross‑model skill sharing.
