Tool-only agents may call `search_skills` instead of retrieving the complete resource list. Search results contain only provider-derived names, descriptions, and canonical main-resource URIs; skill content remains available exclusively through the native resource contract.
For prompts, use the native MCP prompt APIs or their generic tool projection.

This server publishes skills as native `skill://` resources and prompts as native MCP prompt objects. It also exposes `search_skills`, `list_resources`, and `read_resource` tools for agents whose tool catalog does not include direct MCP resource operations.
This server publishes skills as native `skill://` resources, general docs as `resource://docs/{path*}` resources, and workflows as native MCP prompt objects. It intentionally publishes no compatibility tools that mirror resources or prompts.

| Server identity | The initialize response includes a stable name, usage instructions, and a self-contained icon for VS Code's MCP server UI. |
| Tools | Compatibility tools have display titles, structured output schemas, and read-only, idempotent, closed-world annotations. FastMCP's default schema dereferencing remains enabled for clients such as VS Code that require flat schemas. |
| Tools | No tools are published for this documentation-only server surface. Resource and prompt operations stay on native MCP capabilities. |
| Resources | Documentation and skills use native resources and wildcard resource templates with explicit Markdown MIME types. |
| Prompts | Declarative workflows use native prompt objects with descriptions, display titles, typed arguments, and slash-command access. |
| Argument completion | Prompt arguments with authored `choices` are returned through `completion/complete` as the user types. |

In VS Code, skills can arrive through:
1. explicit attachment from `Add Context > MCP Resources` or `MCP: Browse Resources`
2. the `search_skills` and `read_resource` tools for autonomous agents
2. direct resource reads on selected `skill://<name>/SKILL.md` entries
3. a slash-command prompt that names a specific native skill URI
Instructions can steer retrieval, but they do not guarantee automatic resource attachment in every chat surface. When the deferred-tool catalog omits direct MCP resource operations, use the tools; search derives matches from native provider metadata and `read_resource` delegates to the provider without duplicating skill content.
Instructions can steer retrieval, but they do not guarantee automatic resource attachment in every chat surface. Use `MCP: Browse Resources` to confirm server-side availability, then attach only the minimum skill resources needed for the current task.
A reliable prompt is:

Call search_skills with the task or capability and select the best matching skill://.../SKILL.md result. Use read_resource for one selected skill, inspect its _manifest only if supporting detail is needed, and reconcile the guidance with this workspace.
