Run comprehensive validation of the project to ensure all tests, type checks, linting, and deployments are working correctly.

Execute the following commands in sequence and report results:

1. Test Suite

uv run pytest -v

Expected: All tests pass (currently 34 tests), execution time < 1 second

2. Type Checking

uv run mypy app/

Expected: "Success: no issues found in X source files"

uv run pyright app/

Expected: "0 errors, 0 warnings, 0 informations"

3. API Integration Tests

Purpose

Verify external API integrations work correctly with real API calls.

Prerequisites

• All required API keys configured in environment
• APIs must be accessible (network connectivity)
• Test accounts/projects exist in external services

Validation Steps

3.1 Configuration Validation

Check that all required API configuration is present:

# Check environment variables
env | grep -E "(API_KEY|API_TOKEN|LANGSMITH|OPENAI)"

# Verify config file (if applicable)
cat backend/.env | grep -E "^[A-Z_]*API"

Expected:

• All required API keys: SET (not empty)
• Configuration file readable and valid

If Failed:

• Error: Missing API keys
• Action: Check .env file, environment setup

3.2 API Connectivity Tests

Test that each API is accessible and credentials work:

# LangSmith connectivity test
python -c "
from langsmith import Client
client = Client()
projects = list(client.list_projects(limit=1))
print(f'✓ LangSmith: {len(projects)} projects')
"

# OpenAI API test
python -c "
from openai import OpenAI
client = OpenAI()
models = client.models.list(limit=1)
print(f'✓ OpenAI: API accessible')
"

Expected:

• Each API returns successful response
• Credentials validated
• No authentication errors

If Failed:

• Error: Invalid API key / Unauthorized
• Action: Verify API key in dashboard, regenerate if needed

3.3 API Response Format Verification

Verify API responses match expected format:

# Test actual API call and response structure
python -c "
# Test streaming response event types
# Test data structure
# Verify against documented schema
"

Expected:

• Response matches documented schema
• Event types match API documentation
• Data structure is parseable

If Failed:

• Error: Unexpected response format
• Action: Check API version, update integration code

3.4 Integration Flow Test

Test complete integration flow end-to-end:

# Example: Create trace, verify it appears
# Example: Make API call, verify logging
# Example: Test error handling

Expected:

• Complete flow executes successfully
• Data persists correctly
• No integration errors

If Failed:

• Error: Integration flow broken
• Action: Debug with verbose logging, check API status page

Summary

API Integration Tests:
- Configuration: ✅/❌
- Connectivity: ✅/❌
- Response Format: ✅/❌
- Integration Flow: ✅/❌

Note: Skip this section if no external APIs are used.

4. Linting

uv run ruff check .

Expected: "All checks passed!"

4.1 Async Generator Pattern Check

Check for async generators without finally blocks (potential resource leak):

# Find async generators
grep -rn "async def.*yield" --include="*.py" . | grep -v test_ | grep -v "#" > /tmp/async_gens.txt

# For each async generator, check if it has a finally block
if [ -s /tmp/async_gens.txt ]; then
    echo "Checking async generators for finally blocks..."
    while read -r line; do
        file=$(echo "$line" | cut -d: -f1)
        linenum=$(echo "$line" | cut -d: -f2)
        # Check next 30 lines for finally block
        if ! sed -n "${linenum},$((linenum+30))p" "$file" | grep -q "finally:"; then
            echo "⚠️  Potential missing finally block: $line"
        fi
    done < /tmp/async_gens.txt
fi

Expected: No warnings about missing finally blocks (or manual verification that resource cleanup is handled elsewhere)

Why: Async generators need finally blocks to guarantee cleanup (trace closure, DB connections, file handles) even when interrupted

5. Local Server Validation

Start the server in background:

uv run uvicorn app.main:app --host 0.0.0.0 --port 8123 &

Wait 3 seconds for startup, then test endpoints:

curl -s http://localhost:8123/ | python3 -m json.tool

Expected: JSON response with app name, version, and docs link

curl -s -o /dev/null -w "HTTP Status: %{http_code}\n" http://localhost:8123/docs

Expected: HTTP Status: 200

curl -s -i http://localhost:8123/ | head -10

Expected: Headers include x-request-id and status 200

Stop the server:

lsof -ti:8123 | xargs kill -9 2>/dev/null || true

6. Summary Report

After all validations complete, provide a summary report with:

Validation Results:
1. Test Suite: ✅/❌ (X tests passed in Y.Zs)
2. Type Checking: ✅/❌ (mypy + pyright passed)
3. API Integration: ✅/❌/⊘ (connectivity + response validation)
4. Linting: ✅/❌ (ruff check passed)
5. Local Server: ✅/❌ (server starts, endpoints respond)

Overall Status: ✅ PASS / ❌ FAIL / ⚠ PARTIAL

Note: ⊘ = Skipped (no external APIs)

• Any errors or warnings encountered
• Overall health assessment (PASS/FAIL)

Format the report clearly with sections and status indicators (✅/❌)
