Skill collections worth installing.
Whole bundles of agent skills from people who ship with them daily. Linked and credited, never copied, so you always get the current version.
Use the AgentFlows MCP server (https://agentflows.sh/mcp) to pick the skill collection that fits this repo, explain why in two lines, then install it.
