syntaqxCustomize replaces the Marketplace underneath: the agents service reads marketplaces, plugins, skills, subagents and MCP servers in the formats Claude Code reads, so public ones install on g1t as they are. A workspace starts with claude-plugins-official and anthropic-agent-skills and adds marketplaces by owner/repo, a repository here, a git address or a link to marketplace.json; installing a plugin (read from GitHub, from this g1t or from a zip, at a pinned commit) puts its skills in the library as plugin:skill, keeps its subagents as templates to hire from, and turns the remote servers of its .mcp.json into connectors. Connectors are MCP servers the workspace connects once, from the directory, a plugin or an address, signing in with the browser (OAuth with PKCE and dynamic client registration), a key, or not at all, their secrets sealed under CONNECTORS_KEY, and given to every agent, a team or one agent like skills; an agent's turn gets them beside its own servers, so levels, Ask-first cards and audit are unchanged. The linked skills repository is .claude/skills now (.g1t/skills still read). The old extension installs go; requests stay and name plugins, skills and connectors too. In the rail, Agents follows Code, and the top bar's + menu loses Put an agent on it and New workspace.0d75c96History
