User set `model: "sonnet"` in `~/.claude/settings.json` to reduce token spend. Opus was the prior default.

**Why:** Token efficiency — Sonnet is significantly cheaper than Opus for tasks that don't need Opus-class reasoning. User asked for "maximum efficiency for token usage."

**How to apply:** Default to Sonnet for all tasks in this environment unless the user explicitly asks for Opus, names a reasoning-heavy task (architecture, long-horizon planning, hard debugging), or uses a flag like `--opus`. If a task is ambiguous, stay on Sonnet.
