Analyzes CI/CD pipeline logs to diagnose failures and suggest fixes.
Interprets GitHub Actions CI failure logs from PHPUnit, PHPStan, ECS, ESLint, TypeScript, Stylelint, Prettier, Jest, Playwright, ludtwig, and Lighthouse. Filters noise and identifies root causes.
Analyzes and fixes CI/CD pipeline failures including build errors, test failures, and pipeline issues. Detects root causes and suggests corrections while preventing test tampering.
Diagnoses and fixes GitHub Actions CI failures in pull requests by fetching job logs, identifying root causes like build or test errors, and proposing targeted code changes.

# CI Pipeline Failure Analysis

**Commit:** abc1234
**Failed Job:** test-unit
**Duration:** 5m 32s

## Root Cause Analysis
### Primary Failure: Test Assertion Error
**Test:** `OrderTest::test_calculate_total_with_discount`
**File:** `tests/Unit/Domain/OrderTest.php:45`
**Error:**
Failed asserting that 90.0 matches expected 90.
**Analysis:**
The test expects an integer `90` but receives a float `90.0`. This is likely due to:
1. Changed calculation in `Order::calculateTotal()` now returns float
2. Test assertion uses strict comparison
**Suggested Fix:**
```php
// Option 1: Update test to expect float
self::assertSame(90.0, $order->calculateTotal());
// Option 2: Use assertEquals for loose comparison
self::assertEquals(90, $order->calculateTotal());
// Option 3: Use Money value object (recommended)
self::assertTrue($order->calculateTotal()->equals(Money::EUR(90)));
Test: PaymentServiceTest::test_process_payment
File: tests/Unit/Application/PaymentServiceTest.php:78
Error:
Expectation failed for method name is "charge" when invoked 1 time(s).
Method was expected to be called 1 times, actually called 0 times.
Analysis:
Mock expectation not met. The charge method was never called, indicating:
Suggested Fix:
Review the test setup and ensure conditions are met for charge to be called.

## Common Fixes Database
### Dependency Issues
| Error Pattern | Cause | Fix |
|---------------|-------|-----|
| `memory exhausted during composer` | Low memory limit | Add `COMPOSER_MEMORY_LIMIT=-1` |
| `package not found` | Private repo or typo | Check package name and auth |
| `requirements not resolved` | Version conflict | Run `composer why-not package` |
### Test Issues
| Error Pattern | Cause | Fix |
|---------------|-------|-----|
| `Connection refused 127.0.0.1:3306` | MySQL not ready | Add service health check |
| `Mock expectation failed` | Mock not configured | Review mock setup |
| `Class not found` | Autoloader issue | Run `composer dump-autoload` |
### Infrastructure Issues
| Error Pattern | Cause | Fix |
|---------------|-------|-----|
| `no space left on device` | Disk full | Clear Docker cache |
| `Cannot connect to Docker daemon` | DinD not running | Check Docker service |
| `pull access denied` | Auth issue | Add registry credentials |
## Analysis Instructions
1. **Extract log content:**
- Identify job that failed
- Get full log output
- Note timestamps
2. **Identify failure type:**
- Parse error messages
- Categorize (test/lint/infra)
- Determine severity
3. **Root cause analysis:**
- Trace error to source
- Check recent changes
- Identify patterns
4. **Generate recommendations:**
- Specific fixes
- Prevention strategies
- Related improvements
## Usage
Provide:
- CI log output (full or relevant section)
- Pipeline context (branch, commit)
- Recent changes (optional)
The analyzer will:
1. Parse log for errors
2. Categorize failures
3. Identify root cause
4. Suggest specific fixes
5. Provide prevention tips
