Example prompts or workflows

We want a new feature that lets you choose a specific modal that does a particular thing, like Gemina 3 for the front-end and Opus for the back-end. I think it's a fantastic feature.

+1 on this. The use case is cost/latency optimization - not every task needs the most capable model.

Proposed approach: YAML frontmatter in agent definitions

Claude Code solves this with a model field in their agent markdown files:

---
name: fast-linter
description: Quick syntax checks
tools: Bash, Read
model: gpt-4o-mini
---

You are a fast linter for quick syntax validation...

And for heavier work:

---
name: architect
description: System design decisions
tools: Read, Glob, Grep
model: o1
---

You are a senior architect making structural decisions...

Their docs on this:

• Slash commands - model frontmatter
• Subagents - model selection

Implementation options:

model value	Behavior
Model ID (e.g., gpt-4o-mini)	Use that specific model
inherit	Use the session's current model
Omitted	Default model for agents

This would let users optimize their agent fleet - fast/cheap models for atomic tasks, capable models for complex reasoning. The AGENTS.md format already supports YAML frontmatter, so this could slot in naturally.
