crumb-model

# /crumb-model — model + provider config When the user wants to inspect or change Crumb's per-actor model assignment, effort level, or per-provider activation: **Preferred path** — call the `crumb_model` MCP tool. Pass `instruction` for changes, omit for read-only show: - "verifier 모델을 gemini-3-1-pro 로" → instruction sets verifier model (also accepts dot form "gemini-3.1-pro" — normalized to dash) - "effort 다 high 로" → instruction sets all-actor effort=high - "codex 비활성화" → instruction disables codex-local provider - (no instruction) → returns the current config table **Fallback path** — `npx tsx src/index.ts model --apply "<instruction>"` (or `--show` for read-only, or no flag for interactive blessed TUI with Tab/↑↓/←→/p/Enter/Esc). **Interactive TUI** is the operator's choice; the MCP tool is the NL surface (skill / model selection / explicit Korean or English instruction). Output is a status table: - `## providers` — `✓` enabled / `✗` disabled, per local CLI - `## actors` — actor / harness / model / effort, one row per outer actor Defaults (when `.crumb/config.toml` is missing): - coordinator + planner-lead → claude-opus-4-7 / claude-code / high - builder → gpt-5.5-codex / codex / high - verifier → gemini-3-1-pro / gemini-cli / high - builder-fallback → claude-sonnet-4-6 / claude-code / high - All 3 local providers enabled. Explicit slash form: `/crumb-model <instruction>` or `/crumb-model` (show). Reference: `src/config/model-config.ts`, `src/tui/model-edit.ts`, v0.1 §5.1 (resolve order).
