A working index of the skills and plugins from a circulated X-post list. Every repository below was fetched and confirmed to load this session, and two errors in the source post were checked and corrected.
4 sources, one of them an Anthropic monorepo holding several skills.
An agentic skills framework and development methodology for coding agents, distributed as a Claude Code plugin.
Up-to-date, version-specific library documentation delivered into prompts, offered as a CLI, a skill, and an MCP server.

Builds an MCP server from a specification. Lives in the Anthropic monorepo.
Drives a running web app to verify behaviour end to end. Part of the Anthropic monorepo.
Persistent memory across sessions: captures activity, compresses it into summaries, and reinjects context later.

Correction 1, confirmed. Frontend Design is Anthropic's own skill inside anthropics/skills rather than a Leonxlnx repository. The frontend-design directory is present in the monorepo's /skills folder, alongside the separate Taste skill at Leonxlnx/taste-skill. The post appears to have pasted the Taste link a second time under the Frontend Design row.
Correction 2, confirmed. The marketing bundle holds 47 skills. The GitHub contents API listing of coreyhaines31/marketingskills/skills enumerated 47 skill directories this session, which matches Brandon's count over the post's stale figure of 45.
