In the weekend of October 18‑19 2026 I posted a handful of X updates that mixed humor, product advocacy, and technical demos.

- Decision: **Remove most harness features** because they are unnecessary; this aligns with the stance that Claude code worktree tools should also be removed.
- Fact: **.co domains** are “.com‑like, shorter and usually more available.”

These posts also included a tongue‑in‑cheek TLD‑vertical humor list mapping exotic TLDs to countries or concepts, and a note about Epic’s new “agent‑browser snapshot‑delta” feature.

- Fact: The **Roadster demo** rebuilt on AI Gateway using the *deep‑seek‑v4.1‑flash‑1019‑fast* model cost **30 cents**.
- Fact: **Tim Sweeney** reported his Unreal Engine 1 work split as **~30 % deep coding** and **~70 % typing/refactoring**.
- Decision: **Promote Vercel AI Gateway** as the primary way to run business‑critical agents, citing its transparent session metrics, cost control, and data ownership.
