Skills, MCP and plugins
The extensions panel gathers four tabs: Skills, MCP, Plugins and LSP. They all serve the same idea: giving the agent new capabilities without you writing any code.
Skills: packaged instructions
Section titled “Skills: packaged instructions”A Skill is a package of reusable instructions (“how to review a PR”, “how to write my reports”) that the agent activates when the task calls for it. In the Skills tab:
- Installed: your Skills, both the ones that ship with the app and your own.
- Market (skills.sh): search the public Skills catalog and install with one click.
Creating your own Skill
Section titled “Creating your own Skill”The Create skill button opens a form that saves it already in the right format:
- Name (e.g. “PR reviewer”).
- Scope: Global (available in all your projects) or Project (only in the current workspace).
- Description — important: it defines when the Skill activates (“use it when the user asks to review a pull request…”).
- Instructions in Markdown: the step-by-step the AI should follow.
MCP: connecting external tools
Section titled “MCP: connecting external tools”MCP (Model Context Protocol) is the standard for giving the agent external tools: databases, APIs, services. In the MCP tab:
- Installed: your configured MCP servers, with hot reload (“Recargar servidores MCP” — Reload MCP servers).
- Marketplace: a built-in catalog for discovering MCP servers with no API key needed — it combines a curated selection with the official public registry.
- Add MCP by hand: paste the server command (e.g.
-y @scope/server) and choose the scope to save it in.
Plugins
Section titled “Plugins”The Plugins tab lists larger packages that combine several capabilities (for example, web scraping plugins with Puppeteer/Playwright, database administration, CI/CD automation…). You enable and disable them right from the list.
The LSP tab manages the language servers that power autocomplete and diagnostics in the editor: see which ones you have, install them and update them.
