Your race car Claude Code agent.
Keep your Claude Code session under control: watch the context fill up, pit at a clean break, rejoin from the notes.
Install ↓At the first summary, about 1 in 3 anti-cheating rules is lost, and more go with each later compaction.
Instructions on how to work are lost about six times more often than what to build.
Tomorrow you re-explain it all.

Cause: a summary can drop rules that exist only in the conversation. Fix: pit writes them to disk first →
Animated demonstration of the stint band with simulated figures. The band shows a zone emoji, the revs percentage with a ten-cell bar, a stint counter, and a pit board message.
⏸ auto-pit 14:32 when the session sits idle. A dash when it has nothing to say.watch the revs, and the idle countdown on the board ↗
A band above your prompt shows how full the context window is. At 80k tokens it turns 🔥: auto-pit armed. At 60% of the window, 🔶: box this lap. Near the auto-pit ceiling, 🚨: it pits for you.
eyes on the band/pit: the agent writes its notes, the context clears itself, and the notes come back as the first message of a fresh window. Driver change, same race. /pit --save saves without clearing, archives the previous notes in .stint/archive/, and warns if another session rewrote them. Auto-pit does the same by itself when the session sits idle, or when the context reaches its ceiling.
/rejoin: next morning, new session, same stream. The notes go in first. Resuming after the prompt cache has expired re-sends the whole context. On a subscription, the idle auto-pit pits before that happens (details →).
| Zone | From | Do |
|---|---|---|
| 🚀 | under 80k | Keep driving. |
| 🔥 | 80k | auto-pit armed |
| 🔶 | 60% of window | box this lap: /pit or --save |
| 🚨 | ceiling − 10 pts | auto-pit at N% |
Zones are rules of thumb (Horthy 2025). On a window under 200k, 🔥 starts earlier than 80k. The ceiling (N) depends on your window, and 🚨 shows only while auto-pit is on.

| Term | On track | In stint |
|---|---|---|
| revs | Engine revolutions per minute: how hard the engine works. | How full the context window is, shown in the band. |
| redline | The top of the rev counter, where engines break. | The auto-pit ceiling: when the context reaches it, stint pits for you. The band turns 🚨 just before. |
| lap | One turn of the circuit. | One call to the model. |
| stint | The run between two pit stops. | One context window, from fresh to pit. |
| box / pit | The radio call to come in, then the stop. | /pit writes the notes and clears the window. |
| driver change | A fresh driver, same car, same race. | A fresh window that starts from the notes. |
