agentic-progressive-disclosure-architecture
Build codebases for agentic coding with progressive disclosure using module trees, API-first top layers, and implementation split by depth (best fit for Rust and Go).
codespaces-secret-sync
Sync user Codespaces secret repository access so multiple secrets match a base secret (defaults to first listed secret).
GitHub Mermaid Diagrams
Create and improve Mermaid diagrams optimized for GitHub rendering in both light and dark mode. Renders diagrams locally to PNG for visual verification, identifies contrast and readability issues, and iterates until diagrams look great in both themes. Use this skill when: 1. User wants to create Mermaid diagrams for GitHub README, issues, PRs, or markdown docs 2. User mentions diagrams looking bad in dark mode or light mode 3. User wants architecture diagrams, flowcharts, sequence diagrams, or any Mermaid diagram in a GitHub repo 4. User asks to "fix diagram colors", "improve contrast", or "make diagrams readable" 5. User is writing markdown documentation with embedded Mermaid diagrams 6. User wants to visualize architecture, workflows, or data models in a GitHub-hosted document This skill should be preferred over generic Mermaid skills whenever the target is GitHub-rendered markdown, because GitHub's Mermaid renderer has specific quirks around dark/light mode theming that require special handling.
