/pluginThen install plugins individually:
/plugin install office@yesterday-public-plugins
/plugin install personal-agent@yesterday-public-plugins

18 plugins total: 1 external, 5 bundles, 2 MCP servers, 10 standalone skills.
| Plugin | Purpose |
|---|---|
| office | Daily-work core -- 6 generic skills (exa search, excalidraw, slack, GitHub, web/x scrapers) |
| office-extras | Daily-work extras tier -- 4 SaaS integrations (Figma, Miro, Voxtral TTS, VRR) |
| personal-agent | Agent core -- 14 generic agent skills (multi-agent, patrols, self-improvement) |
| systems-operations | Ops core -- 6 skills (opentofu, railway-deploy, butler-deploy, land-and-deploy, canary, setup-deploy) |
| webflow | Ships the Webflow MCP server (.mcp.json, HTTP/OAuth) + the webflow skill -- manage Webflow sites (pages, CMS, assets, styles, publish) |
Single-source MCP-server plugins -- depend on one of these from a bundle instead of redeclaring the server (avoids the Claude Code "MCP server skipped -- same command/URL" dedupe warning).

compile.mjs discovers skills/**/SKILL.md, generates per-skill plugin scaffolds in .compiled/skill-plugins/, and produces .compiled/marketplace.json from the top-level header (./marketplace.json) merged with auto-discovered bundles + standalone.
node clean.mjs # wipe .compiled/ + root symlinks
node compile.mjs # rebuild from sourcesSee .ytstack/DECISIONS.md for the rationale (single Node script, no build infra, symlink-first strategy).
