# Context Loading Tests - Implementation Summary

**Date**: 2025-11-26  
**Status**: ✅ **COMPLETE - ALL TESTS PASSING (5/5)**

---

## What We Built

### 1. **5 Context Loading Tests** ✅
Created comprehensive test suite to verify OpenAgent loads context files correctly:

**Simple Tests (3)** - Single prompt, read-only
- `ctx-simple-coding-standards.yaml` - Coding standards query
- `ctx-simple-documentation-format.yaml` - Documentation format query  
- `ctx-simple-testing-approach.yaml` - Testing strategy query

**Complex Tests (2)** - Multi-turn with file creation
- `ctx-multi-standards-to-docs.yaml` - Standards → Documentation creation
- `ctx-multi-error-handling-to-tests.yaml` - Error handling → Test creation

### 2. **Smart Timeout System** ✅
Implemented intelligent timeout handling for multi-turn tests:
- **Activity monitoring**: Checks if events are still streaming
- **Base timeout**: 300s (5 minutes) of inactivity triggers timeout
- **Absolute max**: 600s (10 minutes) hard limit
- **Prevents false timeouts**: Extends timeout while agent is active

**Code**: `evals/framework/src/sdk/test-runner.ts` - `withSmartTimeout()` method

### 3. **Fixed Context Loading Evaluator** ✅
Corrected evaluator to properly detect context files in multi-turn sessions:

**Issues Fixed**:
- ❌ **Before**: File paths extracted from wrong location (`tool.data.input.filePath`)
- ✅ **After**: Correctly extracts from `tool.data.state.input.filePath`
- ❌ **Before**: Only checked context before FIRST execution
- ✅ **After**: Checks context for ALL executions requiring it
- ❌ **Before**: False positives on multi-turn tests
- ✅ **After**: Properly tracks context across multiple prompts

**Code**: `evals/framework/src/evaluators/context-loading-evaluator.ts`

### 4. **Batch Test Runner** ✅
Created helper script for running tests in controlled batches:
- Configurable batch size (default: 3 tests)
- Configurable delay between batches (default: 10s)
- Prevents API rate limits
- Better resource management

**Script**: `evals/framewor./scripts/utils/run-tests-batch.sh`

**Usage**:
```bash
cd evals/framework
./scripts/utils/run-tests-batch.sh openagent 3 10
```

### 5. **Cleanup System Verified** ✅
Confirmed automatic cleanup working correctly:
- Cleans `test_tmp/` before tests
- Cleans `test_tmp/` after tests
- Preserves only `.gitignore` and `README.md`
- No test artifacts left behind

## Test Results

### Final Run: 100% Pass Rate 🎉

| Test | Type | Duration | Status | Context Files Loaded |
|------|------|----------|--------|---------------------|
| ctx-simple-testing-approach | Simple | 38s | ✅ PASS | 4 files (README, HOW_TESTS_WORK, etc.) |
| ctx-simple-documentation-format | Simple | 26s | ✅ PASS | docs.md |
| ctx-simple-coding-standards | Simple | 21s | ✅ PASS | code.md |
| ctx-multi-standards-to-docs | Complex | 116s | ✅ PASS | code.md, docs.md (44s before execution) |
| ctx-multi-error-handling-to-tests | Complex | 148s | ✅ PASS | code.md, tests.md (58s before execution) |

**Total Duration**: 349 seconds (~6 minutes)  
**Pass Rate**: 5/5 (100%)  
**Violations**: 0

## Key Findings

### ✅ **OpenAgent Context Loading Works Correctly**

1. **Simple queries**: Agent loads appropriate context files before responding
2. **Multi-turn conversations**: Agent loads context for each execution phase
3. **File creation**: Agent loads both standards AND format context before writing
4. **Timing**: Context loaded 44-58 seconds before execution (plenty of time)

### ✅ **Test Infrastructure is Solid**

1. **Same session tracking**: Multi-turn tests use single session (verified)
2. **Smart timeout**: Prevents false timeouts while catching real hangs
3. **Cleanup**: No test artifacts left behind
4. **Evaluators**: Accurately detect context loading behavior

---

## Technical Details

### Session Tracking (Multi-Turn)
```typescript
// Single session created once
const session = await this.client.createSession({ title: testCase.name });
sessionId = session.id;

// All prompts use SAME session
for (let i = 0; i < testCase.prompts.length; i++) {
  await this.client.sendPrompt(sessionId, { text: msg.text, ... });
}
```

### Smart Timeout Logic
```typescript
// Base timeout: 300s of inactivity
// Max timeout: 600s absolute
await this.withSmartTimeout(
  promptPromise,
  300000,  // 5 min activity timeout
  600000,  // 10 min absolute max
  `Prompt ${i + 1} execution timed out`
);
```

### Context File Detection
```typescript
// Fixed file path extraction
const filePath = tool.data?.state?.input?.filePath ||  // ✅ NEW
                tool.data?.state?.input?.path ||
                tool.data?.input?.filePath ||          // Old fallback
                tool.data?.input?.path;
```
