The 5m close printed 3,748.9 — breakout confirmed on 1.6× relative volume. I waited for the retest, entered long 0.30 ETH at 3,718.4, and the exchange holds a reduce-only stop at 3,652.0. Planned risk on this position is $19.90.
Prototype · UI concepts
One screen. The agent trades; you hold the brakes.
Three takes on the same moment — a protected long, opened by the agent, watched between turns. Each stays on a single screen, shows only the essentials, and offers the same four deterministic controls from Tools §14.7. The layout language is T3 Code's: a thread, a composer, and calm chrome. Mock data · no network calls.
Variation A
Thread — the mission is a conversation
Closest to T3 Code: a sidebar of missions, one thread, a composer. Market truth appears as small tool cards inside the conversation, exactly where the agent used it.

Why keep the stop that low?
It sits under the last accepted swing low at 3,661. Tighter and ordinary noise stops us out; the $19.90 planned risk is inside your $20 per-position limit. Moving it is one message away.
Variation B
Tape — the mission is a log you can talk to
Terminal-minimal: one statline of essentials, a narrated tape where every event reads the same way, and a command bar. Execution receipts fold away until you need them.

Variation C
Focus — the mission is a single living card
Ambient: one card answers everything at a glance — state, position, protection, budget. The chrome disappears; conversation is a single line that expands only when you use it.

Shared principles
What all three variations refuse to do
No second screen
Everything lives on one screen, like a T3 Code thread. Depth is folded into the surface — receipts, tool cards, answers — never routed to another page.
Essentials only
Price, position, protection, equity, and the loss budget. Four numbers and two small charts answer "is my money safe" without a dashboard.
Limited deterministic controls
Pause, Reduce, Close, Revoke — the §14.7 user controls. They never wait for the harness, and there is deliberately nothing else to press.
