dax: one prompt rewrote opencode2, and it cost $500
dax says a single prompt from an iOS app rewrote the whole opencode2 server and TUI, with Opus 5.5 driving subagents for $500. Separately he had opencode rewrite the opentunnel backend in Rust and move it to 10 Fly regions live.

Pocock wants agents to build their own CLIs, one reply says scripts rot
Matt Pocock is considering having /retro recommend turning repeated tasks into custom tooling, a CLI plus a skill the agent owns, which he says means fewer tokens and fewer hallucinations. Asmir replied that the real risk is the script quietly failing when the API or repo layout changes, with the agent trusting its output over its own reasoning.

dax had opencode rewrite opentunnel in Rust, then move it live
dax says he had opencode rewrite the opentunnel backend in Rust and move it off Cloudflare onto 10 Fly regions. He says the migration was handled gracefully and everyone's tunnels reconnected to the new system.

dax says Ryan rewrote opencode2's server and TUI from one phone prompt for $500
dax says Ryan rewrote all of opencode2's server and TUI from a single prompt sent from their iOS app, with Opus 5.5 orchestrating a bunch of subagents, at a cost of $500. Separately, Prime Intellect says it ran a swarm of over 2,000 agents for two weeks to rewrite Prime Agent itself in Rust, burning more than 200B GLM-5.3 tokens across 10,000+ sandboxes.
