Suite of tools for creating Practice Hub UI components and artifacts using the project's design system (React, Tailwind CSS, shadcn/ui, glass-card patterns). Use for building UI components that match Practice Hub's established design patterns and conventions.

Conduct structured implementation postmortems to gather feedback on architecture conformance, library friction, and tooling effectiveness. Use when reviewing completed implementations, PRs, or development phases to surface design gaps, boundary violations, and improvement opportunities. Triggers on requests for code review feedback, implementation retrospectives, architecture audits, or library/tooling evaluations.

Plan multi-week Twitter/X campaigns for newsletter growth, content launches, or audience building.Use when creating content calendars, planning thread series, coordinating cross-platform promotion,or designing engagement strategies.

Manage GitHub sub-issues using the gh sub-issue extension. Use this when creating sub-issues, linking issues as sub-issues, listing sub-issues, or managing issue hierarchies.

Use when user wants to implement a feature, build something new, add functionality, or create a component. Also use for creating new projects, repositories, templates, libraries, or any greenfield development. Triggers on "implement X", "build Y", "add feature Z", "create X", "design a new Y", "build a template for Z", "create a repo/project that does X", "start a new project". NOT for bug fixes (use systematic-debugging instead). Orchestrates the complete workflow from requirements gathering through research, design, planning, and parallel implementation with quality gates and review checkpoints at every phase.
