token-saver

Save tokens on Claude. Pick the cheapest model that can do the job — Haiku 4.5 for trivial extraction and Q&A, Sonnet 4.6 for thinking, planning, and most coding, Opus 4.7 only for heavy multi-file execution. Also covers keeping chats tight and using persistent memory files (CLAUDE.md, memory) so Claude doesn't re-derive context every session. Triggers when starting a task, picking a model, mentioning cost or tokens, switching models, when chats are getting long, or when the same context keeps getting re-explained.
