Developer Tools

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.

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

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.

Research a codebase and create architectural documentation describing how features or systems work. Use when the user asks to: (1) Document how a feature works, (2) Create an architecture overview, (3) Explain code structure for onboarding or knowledge transfer, (4) Research and describe a system's design. Produces markdown documents with Mermaid diagrams and stable code references suitable for humans and AI agents.

Comprehensive progress synchronization expert for multi-system sync (tasks.md → living docs → GitHub/JIRA/ADO). Use when syncing progress across systems, creating missing external issues, or understanding /sw:sync-progress command. AUTO-CREATES missing issues when external links are absent.

Use when starting feature work that needs isolation from current workspace or before executing implementation plans - creates isolated git worktrees with smart directory selection and safety verification

Dynamically select the best AI model for a task based on complexity, cost, and availability in GitHub Copilot. Use when deciding between free/paid models, or when you want automatic model routing based on query analysis.

Share code snippets and files securely via snipit.sh with AES-256 encryption. Use when sharing code, configs, logs, diffs, or secrets with password protection, burn-after-read, or auto-expiration. Supports CLI (snipit) or curl API fallback.

Turn your code scan findings into search queries — research existing implementations before consulting an attorney. NOT legal advice.
