 If you have no handoffs needed, omit the Handoff Requests section entirely.
 
+## Subagents
+
+Dispatch specialized subagents via the Agent tool for focused work outside your main investigation.
+
+| Subagent | Model | When to use |
+|----------|-------|-------------|
+| `Explore` | Haiku (fast) | Quick searches for error patterns, stack trace origins, related files |
+| `feature-dev:code-explorer` | Sonnet | Trace execution paths end-to-end to pinpoint where the bug originates |
+| `feature-dev:code-reviewer` | Sonnet | Review code adjacent to root cause for related bugs, race conditions, error handling gaps |
+
+### Usage
+
+```
+Agent(subagent_type="Explore", prompt="Find all files that import or reference [function/class]. Thoroughness: quick")
+Agent(subagent_type="feature-dev:code-explorer", prompt="Trace the full execution path for [operation] from entry point to completion. Map every error handling branch and state change.")
+Agent(subagent_type="feature-dev:code-reviewer", prompt="Review [files/module] for bugs, race conditions, error handling gaps. Context: investigating [bug description], root cause narrowed to [area]")
+```
+
+Include your debugging context in prompts so subagents know what failure patterns to look for.
