Sharp Edges

Overview

Identify error-prone APIs and dangerous configurations that could lead to bugs, security vulnerabilities, or system failures.

When to Use This Skill

Use this skill when you need to identify error-prone APIs and dangerous configurations.

Use this skill when:

Reviewing code for potentially dangerous API usage
Identifying configurations that could cause issues
Analyzing code for error-prone patterns
Assessing risk in API design or configuration choices
Performing security audits focused on API misuse

Instructions

This skill helps identify problematic APIs and configurations:

API Analysis: Review API usage for error-prone patterns
Configuration Review: Identify dangerous or risky configurations
Pattern Recognition: Spot common mistakes and pitfalls
Risk Assessment: Evaluate the potential impact of identified issues

Common Sharp Edges

Error-Prone APIs

APIs with complex parameter requirements
APIs with non-obvious failure modes
APIs that require careful resource management
APIs with timing or concurrency issues
APIs with unclear error handling

Dangerous Configurations

Default settings that are insecure
Configurations that bypass security controls
Settings that enable dangerous features
Options that reduce system reliability
Parameters that affect performance negatively

Detection Strategies

Code Review: Look for known problematic patterns
Static Analysis: Use tools to identify risky API usage
Configuration Audits: Review configuration files for dangerous settings
Documentation Review: Check for warnings about API usage
Experience-Based: Leverage knowledge of common pitfalls

Best Practices

Document identified sharp edges
Provide clear guidance on safe usage
Create examples of correct vs incorrect usage
Recommend safer alternatives when available
Update documentation with findings
