Developer Tools

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

Coordinate parallel code reviews across multiple quality dimensions with finding deduplication, severity calibration, and consolidated reporting. Use this skill when organizing multi-reviewer code reviews, calibrating finding severity, or consolidating review results.

Use when setting up CI/CD pipelines, containerizing applications, or managing infrastructure as code. Invoke for pipelines, Docker, Kubernetes, cloud platforms, GitOps.

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.

Design multi-stage CI/CD pipelines with approval gates, security checks, and deployment orchestration. Use when architecting deployment workflows, setting up continuous delivery, or implementing GitOps practices.

Use when implementing authentication/authorization, securing user input, or preventing OWASP Top 10 vulnerabilities. Invoke for authentication, authorization, input validation, encryption, OWASP Top 10 prevention.

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.

Use when implementing any feature or bugfix, before writing implementation code
