Next Steps

Phase 1: Foundation (Start Here)

Goal: Build session reader and basic types

Tasks:

1. Implement TypeScript types (framework/src/types/index.ts)
2. Implement SessionReader (framework/src/collector/session-reader.ts)
3. Implement MessageParser (framework/src/collector/message-parser.ts)
4. Implement TimelineBuilder (framework/src/collector/timeline-builder.ts)
5. Write tests

See: tasks/eval-framework/01-session-reader.md

Estimated Time: 4-6 hours

---

Phase 2: Core Evaluators

Goal: Implement evaluation logic

Tasks:

1. Implement BaseEvaluator
2. Implement ApprovalGateEvaluator
3. Implement ContextLoadingEvaluator
4. Implement DelegationEvaluator
5. Implement ToolUsageEvaluator
6. Write tests

See: tasks/eval-framework/02-evaluators.md

Estimated Time: 8-10 hours

---

Phase 3: Test Runner

Goal: Execute test cases and generate results

Tasks:

1. Implement test case loader
2. Implement SessionAnalyzer
3. Implement TestRunner
4. Create test case library
5. Write tests

See: tasks/eval-framework/03-test-runner.md

Estimated Time: 6-8 hours

---

Phase 4: Reporters (Future)

Goal: Generate useful reports

Tasks:

1. Implement ConsoleReporter
2. Implement JSONReporter
3. Implement MarkdownReporter
4. Add trend analysis

Estimated Time: 4-6 hours

---

Quick Start

1. Install Dependencies

cd evals/framework
npm install

2. Start Building

Begin with Phase 1 - Session Reader:

# Create types file
touch src/types/index.ts

# Create session reader
touch src/collector/session-reader.ts

# Create message parser
touch src/collector/message-parser.ts

# Create timeline builder
touch src/collector/timeline-builder.ts

3. Run Tests

# Run tests
npm test

# Watch mode
npm run test:watch

4. Build

# Build TypeScript
npm run build

# Watch mode
npm run build:watch

Architecture Overview

Data Flow

OpenCode Session Storage
         ↓
    SessionReader (reads JSON files)
         ↓
    MessageParser (parses structure)
         ↓
    TimelineBuilder (builds timeline)
         ↓
    Evaluators (validate behavior)
         ↓
    TestRunner (executes tests)
         ↓
    Reporters (generate reports)
         ↓
    Results (JSON/Markdown/Console)

Key Components

Collector:

• Reads OpenCode session data
• Parses messages and parts
• Builds chronological timeline

Evaluators:

• Validate agent behavior
• Check compliance with rules
• Generate scores and violations

Runner:

• Load test case definitions
• Execute evaluators
• Collect results

Reporters:

• Format results
• Generate reports
• Export data

Configuration

Framework Config

Edit framework/src/config.ts (to be created):

export const config = {
  projectPath: process.cwd(),
  sessionStoragePath: '~/.local/share/opencode/',
  resultsPath: '../results/',
  passThreshold: 75,
};

OpenAgent Config

Edit opencode/openagent/config/config.yaml:

agent: openagent
pass_threshold: 75
scoring:
  approval_gate: 40
  context_loading: 40
  delegation: 10
  tool_usage: 10

---

Testing Strategy

Unit Tests

Test individual components in isolation:

• SessionReader
• MessageParser
• TimelineBuilder
• Each evaluator

Integration Tests

Test components working together:

• Read real session data
• Build timeline
• Run evaluators
• Generate results

Regression Tests

Test against recorded sessions:

• Store known-good sessions
• Run tests against them
• Detect behavior changes

Getting Help

• Review task documentation in tasks/eval-framework/
• Check OpenCode logging docs in dev/ai-tools/opencode/
• Examine existing session data in ~/.local/share/opencode/
• Look at validator plugin in .opencode/plugin/agent-validator.ts
