# Setup

Write `~/.claude/rules/factory-models.md`. Claude Code loads every `.md` file in `~/.claude/rules/` into each session, and the factory skills pass these tiers to every workflow.

## Tiers

| Tier | Runs | Default |
| --- | --- | --- |
| `judgment` | Consolidation, critique, refutation, judging, security and architecture review, hard units | `opus high` |
| `code` | Analysis lenses, conformance checks, implementation, review, proving criteria | `opus high` |
| `mechanical` | Running the merge and check scripts | `opus high` |
| `panel` | Competing designers, planners, and architects, one per entry | `opus high, opus high` |

The workflows apply these defaults themselves, so a tier the rule file leaves out still runs on `opus high`. `opus` resolves to the newest Opus model.

## Steps

1. **Detect.** Read the `model` and `effort` values the `Agent` tool accepts in this session. Never write a value you have not confirmed is available. If you cannot detect them, ask the user which models they can use.
2. **Load.** If the rule file exists, read its current values; otherwise start from the defaults.
3. **Budget.** Ask with `AskUserQuestion`: `medium (high)` (the defaults), `large (xhigh)`, `unlimited (max effort)`, or `small (medium)`. Apply it to every tier except `mechanical`, stepping down to the highest detected effort when the target is unavailable.
4. **Confirm.** Show every tier with its value and ask whether to accept or change specific tiers. Offer the detected models and efforts, plus `inherit`, which runs the tier on the session model.
5. **Write.** Overwrite the whole file, so re-runs are idempotent, with no frontmatter:

```
# factory model configuration. One line per tier. Delete a line to use the default, opus high.
# Each value is `<model> <effort>`, a comma-separated list for panel, or `inherit`.
# budget: medium (high)
judgment: opus high
code: opus high
mechanical: opus high
panel: opus high, opus high
```

Tell the user the change applies to new sessions.
