compose-skill
Jetpack Compose Agent Skill — AI-powered coding guidance with actual androidx/androidx source code receipts. Works with Claude Code, Codex CLI, Gemini CLI, Cursor, Copilot, Windsurf, and more.
Jetpack Compose Expert https://github.com/aldefy/compose-skill This skill provides Claude with real source code and extensive reference guides for Jetpack Compose. Without it, AI tools often misuse remember, generate inefficient recompositions or misorder modifiers; with the skill, Claude picks the right state primitive, applies stability annotations and orders modifiers correctly. The reference guides cover state management, view composition, performance, navigation, animation, lists, side effects, modifiers, theming, accessibility and deprecated patterns. Installation requires cloning the repository and copying the Jetpack Compose expert skill directory into your skills folder; Claude will automatically activate it when you mention Compose or related API names.

mcp-google-map
18 Google Maps tools and 3 Agent Skills for place search, routes, travel planning, and local SEO—via MCP or standalone CLI.
I hooked up Google Maps to ChatGPT and that was definitely helpful for this; without them it would seemingly just guestimate driving distances, but with the MCP it was able to determine exact driving/walking times and also render maps with waypoints for activities around the lodging.
I used https://github.com/cablate/mcp-google-map for the MCP (and patched it to generate URLs for the maps).
