# Install Rules

## Trigger

- Keywords: install rules, setup rules, copy rules, install-rules

Phase 4: Install (smart merge with manifest tracking)
Phase 4.5: Backfill CLAUDE.md references
Phase 5: Output report

### Arguments

```
$ARGUMENTS
```

| Argument | Description |
|----------|-------------|
| `--all` | Install all available rules |
| `--list` | List available rules without installing |
| `--dry-run` | Show what would be installed, no changes |
| `--force` | Overwrite modified rules |
| `--legacy-strategy <strategy>` | Handle pre-manifest installs (ask/overwrite/skip) |
| `--customize <rule>` | Customize a project-override rule |

### Manifest Tracking

Uses `.sd0x/install-state.json` to track installed file hashes. Smart merge logic:

| Status | Action |
|--------|--------|
| New (not installed) | Copy |
| Unchanged (hash match) | Auto-upgrade |
| Modified by user | Skip (preserve edits) |
| Conflict (both changed) | AskUserQuestion |

### Customize Mode (`--customize`)

Manages `*-project.md` companion files for user overrides:

| Sub-flag | Action |
|----------|--------|
| (none) | Show section status |
| `--add-section` | Add a new section |
| `--update-section <name>` | Update specific section |
| `--reset` | Regenerate from template |
