The band.
Model, effort, context used, cost, the prompt-cache timer and the next message's cost floor, rate limits and tool calls, above the prompt.
Features
The /hud pane.
Context over the session, cost, tokens, limits, tools and files, in tabs.
Ten retro themes.
Hearts, rupees, energy tanks, coins: each theme draws a hero per model and a weapon per effort level, and its world changes as the context fills.
Autopilot.
Optional context notices, a spawn backstop, a compaction guard and effort hints, each switchable on its own.
Open source.
MIT licensed. Every sprite is drawn fresh; the themes are unofficial homages.
