The 3-Tier Skill Architecture in Practice

Short summary

This article introduces a 3-tier model for organizing AI coding skills: Tier 1 for org-wide standards (formatting, naming), Tier 2 for domain methodology (senior practitioner expertise), and Tier 3 for personal workflow patterns. The author audits their own project against the model and finds Tier 2 is the biggest gap — nine issues of accumulated domain methodology with only one converted into a proper skill. For solo projects, the 'org' is the author plus every stateless agent session.

• •3-tier skill model: org-wide standards, domain methodology, personal workflow
• •Tier 2 (domain methodology) is the most common gap — implicit knowledge rarely converted to skills
• •In solo projects, the 'org' includes stateless agent sessions that need Tier 1 skills to avoid re-inventing formats
