About

Five months after the previous video, the author abandons cursor plan mode and now relies on GPT‑5.5 for most coding tasks. Clerk provides unlimited apps on a $20 plan, handling authentication and billing with a Stripe‑compatible component that simplifies pricing tables. DNSimple's SDK lets the author manage domains programmatically in TypeScript, replacing manual DNS handling with simple API calls.

Key points

Toolchain shift

  • Using the Codeex harness as the primary interface because its minimal CLI stays stable while adding powerful features.

Remote workflow

  • Remote development via T3 Code combined with TailScale allows seamless access to Macs and other machines without keeping the laptop open.

Prompt engineering

  • Keeping prompts to two sentences and providing concise examples improves model reliability and reduces unnecessary context.
