prompt-squeeze builds prompt-cost discipline into Claude Code via three surfaces: /squeeze skill that compresses a verbose prompt into a token-efficient equivalent and renders a side-by-side markdown comparison plus a cited receipt (dollars saved, Wh saved, CO₂e at US-grid average). UserPromptSubmit hook that meters every prompt, nudges Claude when ≥25% compressible, and (in interactive mode) blocks prompts above a configurable token limit while showing a 2-column ASCII diff so the user can review before sending. An MCP server exposing personal_stats, team_stats, and weekly_report tools that aggregate the local hook log into shareable rollups.
