Claude Code architecture gets six-layer breakdown

Strong take: this is the right way to think about Claude Code. Most failures here are architecture failures, not model failures, and the article’s value is that it moves the conversation from prompt quality to system design.

• –The six-layer framing is practical: context hygiene, explicit skills, enforced hooks, isolated subagents, and hard verification each solve a different failure mode
• –The prompt-caching discussion is the most actionable part for real users, because it explains why ordering and stable prefixes matter for latency and cost
• –The subagent section is a reminder that isolation matters more than raw autonomy when you’re doing long codebase work
• –The article pushes Claude Code closer to an engineering harness than an assistant, which is exactly where mature AI coding workflows are heading
• –This is more of a tutorial/operating model than product news, but it’s highly relevant for teams already using Claude Code in production
