Developer Tools

Claude Code marketplace publishing - npm publish, GitHub releases, semantic versioning, plugin packaging. Use when publishing plugins.

Systematic code review patterns covering security, performance, maintainability, correctness, and testing — with severity levels, structured feedback guidance, review process, and anti-patterns to avoid. Use when reviewing PRs, establishing review standards, or improving review quality.

Pre-install security scanner for AI agent skills. Detects malicious patterns before you trust code. Local-first — code never leaves your machine.

Centralized n8n hub for designing reliable flows (idempotency, retries, HITL) and operating them via the public REST API. Use for planning, JSON output, and lifecycle actions like list/publish/debug.

Minimize total codebase size through ruthless simplification. Measure success by final code amount, not effort. Bias toward deletion.

Run Codex CLI, Claude Code, OpenCode, or Pi Coding Agent via background process for programmatic control.

Use the Gemini API (Nano Banana image generation, Veo video, Gemini TTS speech and audio understanding) to deliver end-to-end multimodal media workflows and code templates for "generation + understanding".

Code refinement expert that improves clarity, consistency, and maintainability while preserving exact functionality. Use when simplifying complex code, cleaning up recently modified files, or refactoring for readability. Based on Anthropic's official code-simplifier pattern - never alters WHAT code does, only HOW.

Get refactoring suggestions with colored diffs. Use when improving code quality.

Use when working with GitLab CLI (glab) commands across auth, CI/CD, merge requests, issues, releases, repos, and related operations. Routes to specific glab-* sub-skills.

Elixir/Phoenix development companion. Run and interpret mix test, mix credo, mix dialyzer, mix format. Generate modules following OTP conventions: contexts, schemas, GenServers, supervisors, tasks. Debug compilation errors and warnings. Help with Ecto migrations, queries, changesets, and associations. Use for any Elixir or Phoenix development task including writing modules, fixing tests, refactoring code, or understanding OTP patterns.

Conduct rigorous, adversarial code reviews with zero tolerance for mediocrity. Use when users ask to "critically review" my code or a PR, "critique my code", "find issues in my code", or "what's wrong with this code". Identifies security holes, lazy patterns, edge case failures, and bad practices across Python, R, JavaScript/TypeScript, SQL, and front-end code. Scrutinizes error handling, type safety, performance, accessibility, and code quality. Provides structured feedback with severity tiers (Blocking, Required, Suggestions) and specific, actionable recommendations.
