Throwaway code that answers one question. Capture the answer in NOTES.md (required before PRD or /aiops-implement absorption).
Pick a branch
- Logic / state / API shape → tiny interactive terminal app. Pure logic module + thin TUI shell. One command to run. In-memory state unless persistence is the question.
- Look and layout → 3–5 structurally different UI variants on one route, switchable via
?variant=and a floating bottom bar. Prefer embedding in an existing page over a new route.
If ambiguous: match surrounding code (backend → logic; page → UI) and state the assumption.
Rules (both branches)
- Name and locate so it's obviously throwaway, near the code it informs.
- One command to run (
pnpm,python, etc.). - No tests, minimal error handling, no abstractions beyond the question.
- Surface full state after each action or variant switch.
- Delete or absorb when done — don't leave rot.
Logic branch
- State the question in one paragraph before coding.
- Isolate logic in a portable pure module (reducer, state machine, or pure functions). TUI is throwaway.
- TUI: clear screen each tick, show state + keyboard shortcuts, loop until quit.
UI branch
- Variants must differ in layout/hierarchy, not just color.
- Switcher: bottom bar, URL param, arrow keys (skip when input focused), hidden in production.
- Winner gets folded into real code; losers and switcher deleted.
