Usage 0.20.1: Context window nudge refocused on quality and triggers

Release notes

FEATURE

Context window nudge refocused on quality and triggers earlier

The notification nudging you to clean up your chat's context window (context — the range of previous messages the AI remembers) now jumps out earlier at 70%, and it no longer bothers lecturing you on costs, but focuses on preserving quality. This is because the model starts forgetting the middle parts of long conversations well before the context is actually full. So now it warns you right before quality drops: use /clear when switching tasks, or /compact if you want to continue but keep the focus. It's like studying: rather than waiting until your brain is 100% full to take a break, it's better to pause at 70%—before you start spacing out—and summarize the key points.

Original changelog

Original changelogContext window nudge refocused on quality and triggers earlier

**Context-window nudge reframed around quality, and fires earlier (≥70%)**: the status line reminder added in 0.20.0 was framed around cost, but Claude Code (and Codex) auto-compact at ~80% and prompt caching makes resent context cheap — so the cost angle added little. What actually degrades as a conversation grows is quality: models lose the middle of long inputs well before the window fills. The nudge now triggers at 70% — ahead of the lossy automatic compaction — and suggests taking control yourself: `/clear` when switching tasks, or `/compact` to keep the focus you choose. The dollar figure was dropped.
