Crumb Model

Show or change Crumb per-actor model + effort + per-provider activation (claude-local / codex-local / gemini-cli-local). Defaults to all high-end models (claude-opus-4-7 / gpt-5.5-codex / gemini-3-1-pro) + effort=high. Gemini model IDs accept both dot ("gemini-3.1-pro") and dash ("gemini-3-1-pro") forms — internally normalized. Trigger on "verifier 모델을 X 로", "set builder model to Y", "effort 다 high 로", "effort all to low", "codex 비활성화", "disable gemini", "어떤 모델 쓰고 있어?", "모델 설정 보여줘", "show model config", "어떤 effort?", or any per-actor / per-provider tuning request. Read-only when no instruction given. Do NOT trigger for preset recommendation (use `crumb-config` skill) or environment readiness (use `crumb-doctor` skill).

File contents

/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).
