ConsolePatrol Skill

Name

console-patrol

Description

AI-First Console Error & Warning Detector for Web Applications. Automatically scans web pages to detect console errors and warnings, with framework-specific rules for Ant Design, React, and Element UI.

When to Use

Use this skill when the user asks to:

• "Check for console errors"
• "Scan pages for warnings"
• "Audit a web app"
• "Find issues in the application"
• "Debug console output"
• Fixing React/antd/Element UI warnings

Prerequisites

The skill uses console-patrol package:

pip install console-patrol
playwright install chromium

Core Workflow

1. Quick Scan (Recommended)

from console_patrol import ConsolePatrol

patrol = ConsolePatrol()
result = patrol.scan(
    url="http://localhost:3000",
    routes=[
        "http://localhost:3000/",
        "http://localhost:3000/dashboard",
        "http://localhost:3000/settings",
    ],
    wait_time=2.0,
)

print(f"Issues found: {result.report.total_issues}")
for issue in result.issues:
    print(f"[{issue.severity.value}] {issue.rule_id}")
    print(f"  Fix: {issue.suggestion}")

2. Auto-Discover Routes

from console_patrol import ConsolePatrol

patrol = ConsolePatrol()
result = patrol.scan(
    url="http://localhost:3000",
    router_type="react",
    base_path="/admin",
    auto_discover=True,  # Auto-discover common routes
)

3. With Framework Auto-Detection

result = patrol.scan(
    url="http://localhost:3000",
    routes=["http://localhost:3000/"],
    detect_framework=True,  # Auto-detect UI framework
)
print(f"Detected: {result.framework_info.ui_framework}")

4. CLI Usage

# Scan with auto-discovery
console-patrol scan http://localhost:3000 --router-type react --auto-discover

# Scan specific routes
console-patrol scan http://localhost:3000 --routes "/,/dashboard,/about"

# With screenshots on errors
console-patrol scan http://localhost:3000 --screenshot

# Output formats
console-patrol scan http://localhost:3000 --format markdown

Detection Rules

Severity Levels

Level	Meaning	Exit Code
P0	Fatal (crashes, JS exceptions)	2
P1	Warning (framework issues)	1
P2	Hint (code smell)	0

Built-in Rules

Ant Design

• antd-useForm-unhooked (P1): form.getFieldValue() called outside Form
• antd-modal-context (P1): Static modal in React 18
• antd-tree-missing-keys (P1): Tree wildcard keys
• antd-table-duplicate-key (P0): Duplicate key in Table

React

• react-uncaught-error (P0): Uncaught JS exception
• react-chunk-load-error (P0): Module load failure
• react-hooks-rules (P1): Hooks violation
• react-list-missing-key (P2): Missing key prop

Response Format

When issues are found, respond with:

## ConsolePatrol Scan Results

**Pages Scanned:** N
**Total Issues:** N

| Severity | Count |
|----------|-------|
| P0 (Fatal) | N |
| P1 (Warning) | N |
| P2 (Hint) | N |

### Issues

**[P0] react-uncaught-error**
- Message: Error description
- Location: page URL
- Fix: Suggestion

**[P1] antd-useForm-unhooked**
- Message: Error description
- Location: page URL
- Fix: Use state instead of form.getFieldValue() in render

Important Notes

1. Wait Time: Default 2s after page load. Increase for SPAs with lazy loading.
2. Screenshots: Use --screenshot flag to capture error screenshots.
3. Frameworks: Pass --frameworks antd,react to limit rule scope.
4. Exit Codes: Use in CI/CD: if [ $? -gt 0 ]; then echo "Issues found"; fi

Installation for Agent

If console-patrol is not installed:

import subprocess
subprocess.run(["pip", "install", "console-patrol"], check=True)
subprocess.run(["playwright", "install", "chromium"], check=True)

Edge Cases

• Page not loading: Timeout is 30s by default. Check if dev server is running.
• No issues found: Report success, no action needed.
• P0 issues: Always highlight as critical, suggest immediate fix.
• Framework not detected: Use default rules (antd, react, element).
