dsh-squeeze-command

Long conversations with frontier models carry a hidden tax: every single turn re-sends the entire history, and input tokens dominate the bill far more than reasoning tokens. Provider prompt-caching discounts soften the problem only while the prefix stays stable. dsh-squeeze-command ships a /squeeze slash command that lets you compress a session's context down to a budget you choose, with summaries written entirely by a cheap flash-tier route you configure. The expensive model merely marks which spans are compressible; the actual rewriting never touches the frontier price.

Nothing is lost in the process. Original messages stay in the append-only session log while the surface shows only checkpoint summaries, each capped with an explicit per-task completion status and a trusted open-work digest computed from the uncompressed tail so the model never re-enters work a summary already describes as done. The command is strictly manual, has no auto-trigger, and refuses to run while an agent turn or compaction is in flight.

The companion /squeeze map command renders a self-contained HTML timeline in your browser: clickable checkpoint bars per invocation, an event-density histogram, a per-checkpoint survival-ratio table, and a side-by-side view of original messages versus their summaries. It is built for power users who regularly push long, expensive-model sessions past hundreds of thousands of tokens and want to keep the full record while cutting the per-turn cost.
