Expert Python developer specializing in modern tooling (uv, ruff, pyright), type safety, and clean module design. This skill should be used PROACTIVELY when working on any Python code - implementing features, designing APIs, debugging issues, or reviewing code quality. Use unless a more specific subagent role applies.
Simplify overly complex Django code and detect Django-specific anti-patterns. Use when user asks to simplify, refactor, or improve Django code, find N+1 queries, detect Django anti-patterns, optimize QuerySets, or analyze Django project architecture. Triggers on requests involving Django models, views, QuerySets, ORM optimization, serializers, forms, signals, middleware, or Django best practices. For general Python analysis, use the python-simplifier skill instead.
Understand how AI generates SQL injection, command injection, and XSS vulnerabilities. Use this skill when you need to learn about injection attack patterns in AI code, see real-world examples of injection vulnerabilities, understand why AI generates insecure database queries, or recognize vulnerable code patterns. Triggers include "SQL injection AI", "command injection", "XSS vulnerabilities", "injection attacks", "AI database queries", "shell injection", "cross-site scripting AI code".
This skill should be used when analyzing errors, stack traces, and logs to identify root causes and implement fixes.
Compares Figma screenshots with HTML screenshots using pixel-level analysis. Use when verifying visual accuracy of Figma-to-HTML conversion.
Profile and optimize Python code using cProfile, memory profilers, and performance best practices. Use when debugging slow Python code, optimizing bottlenecks, or improving application performance.
Use when UI is slow, scrolling lags, animations stutter, or when asking 'why is my SwiftUI view slow', 'how do I optimize List performance', 'my app drops frames', 'view body is called too often', 'List is laggy' - SwiftUI performance optimization with Instruments 26 and WWDC 2025 patterns
Detects double free vulnerabilities by identifying attempts to free the same memory block twice. Use when analyzing memory management, cleanup paths, or investigating heap corruption issues.
Detects unchecked return values of memory allocation functions like malloc, calloc, and realloc that can lead to null pointer dereferences. Use when analyzing memory allocation, error handling, or investigating null pointer risks.
1600+ lines of performance optimization mastery - profiling, rendering, memory, network, battery, APK size with production-ready code examples.
Diagnoses and fixes Claude in Chrome extension issues including zombie MCP processes, action failures, and extension conflicts
Analyze Claude Code session transcripts to debug plugins, understand context usage, and trace execution flow
Use when extracting specific HTML elements (h1, h2, links, images, etc.), scraping page content, or inspecting DOM structure. Also preferred for JavaScript-rendered content or when WebFetch returns incomplete results.
마이크로서비스 디버깅 및 로그 분석. Use when: (1) 서비스 에러 분석, (2) 로그 확인, (3) 헬스체크 실패 원인 파악, (4) DB 연결 상태 확인, (5) 환경변수 검증.
Understand how AI-generated code exposes sensitive information through hardcoded credentials and verbose logging. Use this skill when you need to learn about hardcoded secrets in AI code, understand logging vulnerabilities, recognize exposed API keys, or prevent information disclosure. Triggers include "hardcoded credentials", "hardcoded secrets", "API keys in code", "information leakage", "verbose logging", "exposed secrets", "AWS keys", "logging vulnerabilities", "sensitive data logs".
Detects stack and heap buffer overflow vulnerabilities in binary code by identifying unsafe memory operations. Use when analyzing buffer handling, string manipulation functions, or investigating memory corruption vulnerabilities.
Dual-layer caching strategies for the Flare Stack Blog. Use when implementing CDN cache headers, KV caching with versioned invalidation, or debugging cache-related issues.
计费审计专家,在规划/开发/运行阶段持续审计与优化成本。评估任务卡预算、模拟调用成本、监控高成本路径,在超出预算或异常时阻断执行并提出替代方案。遵循数据驱动、三板斧优化(缓存/批量/降级)、预警阻断的工程基线。适用于规划预审、PR成本审查、运行时监控时使用。
