resolveModel(input)
|
||||
1. Override: UI-selected model (primary agents only)
|
||||
2. Category default: From category config
|
||||
3. Provider fallback: AGENT_MODEL_REQUIREMENTS chains
|
||||
4. System default: Ultimate fallback
|
||||
```
|
||||
|
||||
Key files: `model-resolver.ts` (entry), `model-resolution-pipeline.ts` (orchestration), `model-requirements.ts` (fallback chains), `model-name-matcher.ts` (fuzzy matching).
|
||||
|
||||
## MIGRATION SYSTEM
|
||||
|
||||
Automatically transforms legacy config on load:
|
||||
- `agent-names.ts`: Old agent names → new (e.g., `junior` → `sisyphus-junior`)
|
||||
- `hook-names.ts`: Old hook names → new
|
||||
- `model-versions.ts`: Old model IDs → current
|
||||
- `agent-category.ts`: Legacy agent configs → category system
|
||||
|
||||
## MOST IMPORTED
|
||||
|
||||
| Utility | Imports | Purpose |
|
||||
|---------|---------|---------|
|
||||
| logger.ts | 62 | Background task visibility |
|
||||
| data-path.ts | 11 | XDG storage resolution |
|
||||
| model-requirements.ts | 11 | Agent fallback chains |
|
||||
| system-directive.ts | 11 | System message filtering |
|
||||
| frontmatter.ts | 10 | YAML metadata extraction |
|
||||
| permission-compat.ts | 9 | Tool restrictions |
|
||||
| file-utils.ts | 9 | File operations |
|
||||
| dynamic-truncator.ts | 7 | Token-aware truncation |
|
||||
|
||||
## KEY PATTERNS
|
||||
|
||||
**3-Step Model Resolution** (Override → Fallback → Default):
|
||||
1. **Override**: UI-selected or user-configured model
|
||||
2. **Fallback**: Provider/model chain with availability checking
|
||||
3. **Default**: System fallback when no matches found
|
||||
|
||||
**System Directive Filtering**:
|
||||
```typescript
|
||||
if (isSystemDirective(message)) return // Skip system-generated
|
||||
const directive = createSystemDirective("TODO CONTINUATION")
|
||||
```
|
||||
|
||||
## ANTI-PATTERNS
|
||||
|
||||
- **Raw JSON.parse**: Use `jsonc-parser.ts` for comment support
|
||||
- **Hardcoded paths**: Use `opencode-config-dir.ts` or `data-path.ts`
|
||||
- **console.log**: Use `logger.ts` for background task visibility
|
||||
- **Unbounded output**: Use `dynamic-truncator.ts` to prevent overflow
|
||||
- **Manual version check**: Use `opencode-version.ts` for semver safety
|
||||
| Utility | Import Count | Purpose |
|
||||
|---------|-------------|---------|
|
||||
| `logger.ts` | 62 | `/tmp/oh-my-opencode.log` |
|
||||
| `data-path.ts` | 11 | XDG storage resolution |
|
||||
| `model-requirements.ts` | 11 | Agent fallback chains |
|
||||
| `system-directive.ts` | 11 | System message filtering |
|
||||
| `frontmatter.ts` | 10 | YAML metadata extraction |
