Kieran Klaassen, CTO and developer advocate who built the Compound Engineering plugin, explains systems that make Claude Code improve with use. He breaks down plan-work-assess-compound loops. Demos show workflows for planning, using skills for just-in-time context, AI-driven QA with Playwright, multi-perspective automated code reviews, and the LFG command to go from 0 to production.

Episode notes
Write Learnings Back Into Repo
- When you spot a recurring mistake, 'compound' it by writing the fix into repo docs or ClaudeMD immediately.
- That stored guidance will automatically be injected into future plans and prompts.
Trust Versus Control Shift
- Kieran contrasts two engineering mindsets: full oversight vs. trusting AI with guarded systems.
- He argues it's okay to trust AI if you capture failures and teach the model to avoid them next time.
Train Agents Like New Hires
- Treat early agent interactions like onboarding: invest effort teaching the agent your patterns, then let it run end-to-end.
- Over time the agent becomes trustworthy for larger, more autonomous tasks.
