**Spend Claude on thinking, not chores.** A Claude Code mod.  A real, unedited session: Claude hands a 6,000 line log to free Gemini and gets back a timeline. Two ways to spend Claude on thinking instead of chores: 1. **Helper subagents** (Explore and friends) that don't ask for a model run on Haiku. 2. **`summarize_free`**, a tool Claude can call to hand a big file or log to a free Gemini model and get back only what it needs. Gemini models are tried in order (Lite first), so one being busy doesn't stop it. A line above the prompt counts what went where; `/frugal status` adds all-time totals. An honest note from making the demo: for "find the error" questions Claude reaches for Grep, which is cheaper still. `summarize_free` earns its place on summaries, timelines and questions grep can't answer, or whenever you ask for it.
