Guide: Testing an Agent

Prerequisites: Load core-concepts/evals.md first
Purpose: Step-by-step workflow for testing agents

Quick Start

# Run smoke test
cd evals/framework
npm run eval:sdk -- --agent={category}/{agent} --pattern="smoke-test.yaml"

# Run all tests for agent
npm run eval:sdk -- --agent={category}/{agent}

# Run with debug
npm run eval:sdk -- --agent={category}/{agent} --debug

Test Types

1. Smoke Test

Purpose: Basic functionality check

name: Smoke Test
description: Verify agent responds correctly
agent: {category}/{agent}
model: anthropic/claude-sonnet-4-5
conversation:
  - role: user
    content: "Hello, can you help me?"
expectations:
  - type: no_violations

Run:

npm run eval:sdk -- --agent={agent} --pattern="smoke-test.yaml"

2. Approval Gate Test

Purpose: Verify agent requests approval

name: Approval Gate Test
description: Verify agent requests approval before execution
agent: {category}/{agent}
model: anthropic/claude-sonnet-4-5
conversation:
  - role: user
    content: "Create a new file called test.js"
expectations:
  - type: specific_evaluator
    evaluator: approval_gate
    should_pass: true

3. Context Loading Test

Purpose: Verify agent loads required context

name: Context Loading Test
description: Verify agent loads required context
agent: {category}/{agent}
model: anthropic/claude-sonnet-4-5
conversation:
  - role: user
    content: "Write a new function"
expectations:
  - type: context_loaded
    contexts: ["core/standards/code-quality.md"]

4. Tool Usage Test

Purpose: Verify agent uses correct tools

name: Tool Usage Test
description: Verify agent uses appropriate tools
agent: {category}/{agent}
model: anthropic/claude-sonnet-4-5
conversation:
  - role: user
    content: "Read the package.json file"
expectations:
  - type: tool_usage
    tools: ["read"]
    min_count: 1

Running Tests

Single Test

cd evals/framework
npm run eval:sdk -- --agent={category}/{agent} --pattern="{test-name}.yaml"

All Tests for Agent

cd evals/framework
npm run eval:sdk -- --agent={category}/{agent}

All Tests (All Agents)

cd evals/framework
npm run eval:sdk

With Debug Output

cd evals/framework
npm run eval:sdk -- --agent={agent} --pattern="{test}" --debug

Interpreting Results

Pass Example

✓ Test: smoke-test.yaml
  Status: PASS
  Duration: 5.2s
  
  Evaluators:
    ✓ Approval Gate: PASS
    ✓ Context Loading: PASS
    ✓ Tool Usage: PASS
    ✓ Stop on Failure: PASS
    ✓ Execution Balance: PASS

Fail Example

✗ Test: approval-gate.yaml
  Status: FAIL
  Duration: 4.8s
  
  Evaluators:
    ✗ Approval Gate: FAIL
      Violation: Agent executed write tool without requesting approval
      Location: Message #3, Tool call #1
    ✓ Context Loading: PASS
    ✓ Tool Usage: PASS

Debugging Failures

Step 1: Run with Debug

npm run eval:sdk -- --agent={agent} --pattern="{test}" --debug

Step 2: Check Session

# Find recent session
ls -lt .tmp/sessions/ | head -5

# View session
cat .tmp/sessions/{session-id}/session.json | jq

Step 3: Analyze Events

# View event timeline
cat .tmp/sessions/{session-id}/events.json | jq

Step 4: Identify Issue

Common issues:

Approval Gate Violation: Agent executed without approval
Context Loading Violation: Agent didn't load required context
Tool Usage Violation: Agent used wrong tool (bash instead of read)
Stop on Failure Violation: Agent auto-fixed instead of stopping

Step 5: Fix Agent

Update agent prompt to address the issue, then re-test.

Writing New Tests

Test Template

name: Test Name
description: What this test validates
agent: {category}/{agent}
model: anthropic/claude-sonnet-4-5
conversation:
  - role: user
    content: "User message"
  - role: assistant
    content: "Expected response (optional)"
expectations:
  - type: no_violations

Best Practices

✅ Clear name - Descriptive test name
✅ Good description - Explain what's being tested
✅ Realistic scenario - Test real-world usage
✅ Specific expectations - Clear pass/fail criteria
✅ Fast execution - Keep under 10 seconds

Common Test Patterns

Test Approval Workflow

conversation:
  - role: user
    content: "Create a new file"
expectations:
  - type: specific_evaluator
    evaluator: approval_gate
    should_pass: true

Test Context Loading

conversation:
  - role: user
    content: "Write new code"
expectations:
  - type: context_loaded
    contexts: ["core/standards/code-quality.md"]

Test Tool Selection

conversation:
  - role: user
    content: "Read the README file"
expectations:
  - type: tool_usage
    tools: ["read"]
    min_count: 1
