 The skill derives `owner/repo` from git remote, runs the CLI, launches parallel evaluations for docs and policy, and writes detailed reports to `results/`.

-**Other SDKs:** Your SDK needs an "everything server" — an HTTP server at `/mcp` implementing the [Streamable HTTP transport](https://modelcontextprotocol.io/specification/draft/basic/transports.md) with all MCP features (tools, resources, prompts, etc.). See the [TypeScript](https://github.com/modelcontextprotocol/typescript-sdk/tree/v1.x/test/conformance) or [Python](https://github.com/modelcontextprotocol/python-sdk/tree/v1.x/examples/servers/everything-server) implementations as reference.

+cd ~/src/mcp/go-sdk
+go build -o /tmp/go-conformance-server ./conformance/everything-server
+go build -o /tmp/go-conformance-client ./conformance/everything-client

 Start your everything server, then pass `--conformance-server-url`. Pass `--client-cmd` if your SDK has a conformance client. If neither exists yet, use `--skip-conformance` — the scorecard will note this as a gap.
