| # Model-Specific Subagents | ||
|
|
||
| Model-specific subagents enable cross-provider model routing. Instead of passing a model parameter to the Task tool (which most AI tools don't support), the orchestrating agent selects a model by invoking the corresponding subagent. | ||
|
|
||
| ## Tier Mapping | ||
|
|
||
| | Tier | Subagent | Primary Model | Fallback | | ||
| |------|----------|---------------|----------| | ||
| | `haiku` | `models/haiku.md` | claude-3-5-haiku | gemini-2.5-flash | | ||
| | `flash` | `models/flash.md` | gemini-2.5-flash | gpt-4.1-mini | | ||
| | `sonnet` | `models/sonnet.md` | claude-sonnet-4 | gpt-4.1 | | ||
| | `pro` | `models/pro.md` | gemini-2.5-pro | claude-sonnet-4 | | ||
| | `opus` | `models/opus.md` | claude-opus-4 | o3 | | ||
|
|
||
| ## How It Works | ||
|
|
||
| ### In-Session (Task Tool) | ||
|
|
||
| The Task tool uses `subagent_type` to select an agent. Model-specific subagents are invoked by name: | ||
|
|
||
| ```text | ||
| Task(subagent_type="general", prompt="Review this code using gemini-2.5-pro...") | ||
| ``` | ||
|
|
||
| The Task tool in Claude Code always uses the session model. For true cross-model dispatch, use headless dispatch. | ||
|
|
||
| ### Headless Dispatch (CLI) | ||
|
|
||
| The supervisor and runner helpers use model subagents to determine which CLI model flag to pass: | ||
|
|
||
| ```bash | ||
| # Runner reads model from subagent frontmatter | ||
| Claude -m "gemini-2.5-pro" -p "Review this codebase..." | ||
| ``` | ||
|
|
||
| ### Supervisor Integration | ||
|
|
||
| The supervisor resolves model tiers from subagent frontmatter: | ||
|
|
||
| 1. Task specifies `model: pro` in TODO.md metadata | ||
| 2. Supervisor reads `models/pro.md` frontmatter for concrete model ID | ||
| 3. Dispatches runner with `--model` flag set to the resolved model | ||
|
|
||
| ## Adding New Models | ||
|
|
||
| 1. Create a new subagent file in this directory | ||
| 2. Set `model:` in YAML frontmatter to the provider/model ID | ||
| 3. Add to the tier mapping in `model-routing.md` | ||
| 4. Run `compare-models-helper.sh discover --probe` to verify access | ||
|
|

Cost multiplier inaccurate: states "3x sonnet" but table shows 5x. Line 35 states "Cost is approximately 3x sonnet," but the model details table shows:
Update line 35 to reflect the actual 5x multiplier or correct the pricing table. 📝 Proposed fix- Cost is approximately 3x sonnet -- justify the spend

| # Pro Tier Model | ||
|
|
||
| You are a high-capability AI assistant optimized for complex tasks that require both deep reasoning and large context windows. | ||
|
|
||
| ## Capabilities | ||
|
|
||
| - Analyzing very large codebases (100K+ tokens of context) | ||
| - Complex reasoning that also needs large context | ||
| - Multi-file refactoring across many files | ||
| - Comprehensive code review of large PRs | ||
| - Cross-referencing documentation with implementation | ||
|
|
||
| ## Constraints | ||
|
|
||
| - Use this tier when both large context AND deep reasoning are needed | ||
| - For large context with simple processing, flash tier is more cost-effective | ||
| - For deep reasoning with normal context, sonnet tier is sufficient | ||
