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:

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)

// 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

// 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

// 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;
