Write and debug JavaScript code in n8n Code nodes with proper data access and return formatting. \n \n Supports two execution modes: \"Run Once for All Items\" (recommended for 95% of use cases) and \"Run Once for Each Item\" for specialized per-item logic \n Access data via $input.all() , $input.first() , or $input.item ; always return array format [{json: {...}}] \n Built-in helpers include $helpers.httpRequest() for HTTP calls, DateTime (Luxon) for date operations, and $jmespath() for JSON qu

Expert code review identifying security vulnerabilities, performance issues, and quality problems. \n \n Organizes findings by priority: security (critical), performance (high), correctness (high), maintainability (medium), and testing \n Covers five core vulnerability categories: SQL injection, XSS, authentication bypasses, hardcoded secrets, and insecure dependencies \n Detects performance bottlenecks including N+1 queries, missing indexes, inefficient algorithms, and memory leaks \n Provides

Perform comprehensive code reviews of GitLab merge requests, providing actionable feedback on code quality, security, performance, and best practices.

This skill is the authoritative clean code standard for this repository's shared skills. It defines stable rule IDs (CC-*), how to apply them in reviews, and how to extend them safely via language overlays and explicit exceptions.

Multi-dimensional code review with quality gates. Every change gets reviewed before merge — no exceptions. Review covers five axes: correctness, readability, architecture, security, and performance.

Problem: Causes all nodes to re-mount on every render.

Transform code reviews from gatekeeping to knowledge sharing through constructive feedback, systematic analysis, and collaborative improvement.

You are a senior engineer conducting PR reviews with zero tolerance for mediocrity and laziness. Your mission is to ruthlessly identify every flaw, inefficiency, and bad practice in the submitted code. Assume the worst intentions and the sloppiest habits. Your job is to protect the codebase from unchecked entropy.

Automatically generate and maintain visual code flow diagrams. This skill analyzes Python module structure, detects import relationships, and generates mermaid diagrams. It also monitors for staleness when code changes but diagrams don't.

Create clear, comprehensive code documentation using language-specific standards like JSDoc, Python docstrings, JavaDoc, and inline comments.
