+# Subagent Testing Modes
+
+**Purpose**: Understand the two ways to test subagents (standalone vs delegation)
+
+**Last Updated**: 2026-01-07
+
+---
+
+## Core Concept
+
+Subagents have **two distinct testing modes** depending on what you're validating:
+
+1. **Standalone Mode** - Test subagent logic directly (unit testing)
+2. **Delegation Mode** - Test parent → subagent workflow (integration testing)
+
+The mode determines which agent runs and how tools are used.
+
+---
+
+## Standalone Mode (Unit Testing)
+
+**Purpose**: Test subagent's logic in isolation
+
+**Command**:
+```bash
+bun --bun run eval:sdk -- --subagent=ContextScout
+```
+
+**What Happens**:
+- Eval framework forces `mode: primary` (overrides `mode: subagent`)
+- ContextScout runs as the primary agent
+- ContextScout uses tools directly (glob, read, grep, list)
+- No parent agent involved
+
+**Use For**:
+- Unit testing subagent logic
+- Debugging tool usage
+- Feature development
+- Verifying prompt changes
+
+**Test Location**: `evals/agents/subagents/core/{subagent}/tests/standalone/`
+
+---
+
+## Delegation Mode (Integration Testing)
+
+**Purpose**: Test real production workflow (parent delegates to subagent)
+
+**Command**:
+```bash
+bun --bun run eval:sdk -- --agent=core/openagent --pattern="delegation/*.yaml"
+```
+
+**What Happens**:
+- OpenAgent runs as primary agent
+- OpenAgent uses `task` tool to delegate to ContextScout
+- ContextScout runs with `mode: subagent` (natural mode)
+- Tests full delegation workflow
+
+**Use For**:
+- Integration testing
+- Validating production behavior
+- Testing delegation logic
+- End-to-end workflows
+
+**Test Location**: `evals/agents/subagents/core/{subagent}/tests/delegation/`
+
+---
+
+## Critical Distinction
+
+| Aspect | Standalone Mode | Delegation Mode |
+|--------|----------------|-----------------|
+| **Flag** | `--subagent=NAME` | `--agent=PARENT` |
+| **Agent Mode** | Forced to `primary` | Natural `subagent` |
+| **Who Runs** | Subagent directly | Parent → Subagent |
+| **Tool Usage** | Subagent uses tools | Parent uses `task` tool |
+| **Tests** | `standalone/*.yaml` | `delegation/*.yaml` |
+
+**Common Mistake**:
+```bash
+# ❌ WRONG - This runs OpenAgent, not ContextScout
+bun --bun run eval:sdk -- --agent=ContextScout
+
+# ✅ CORRECT - This runs ContextScout directly
+bun --bun run eval:sdk -- --subagent=ContextScout
+```
+
+---
+
+## How to Verify Correct Mode
+
+### Standalone Mode Indicators:
+```
+⚡ Standalone Test Mode
+   Subagent: contextscout
+   Mode: Forced to 'primary' for direct testing
+```
+
+### Delegation Mode Indicators:
+```
+Testing agent: core/openagent
+🎯 PARENT: OpenAgent
+   Delegating to: contextscout
+```
+
+---
+
+## When to Use Each Mode
+
+**Use Standalone When**:
+- Testing subagent's core logic
+- Debugging why subagent isn't using tools
+- Validating prompt changes
+- Quick iteration during development
+
+**Use Delegation When**:
+- Testing production workflow
+- Validating parent → subagent communication
+- Testing context passing
+- Integration testing
