Claude Subscription DirectSDK is an experimental, officially maintained Hermes Agent model-provider plugin from Nous Research. Rather than calling Anthropic's API directly, it drives the unmodified official Claude Code CLI as a request-scoped model client, speaking Claude Code's native stream-json protocol without depending on the Python Agent SDK package. Hermes keeps its own agent loop, tool execution, approval flow and context compaction; the plugin only supplies model responses sourced from whatever Claude Pro or Max subscription the installed claude CLI is logged into, avoiding metered API billing for those calls. It requires a recent Hermes Agent build (0.21.4 or a specific main commit), Python 3.10+, and the official Claude Code CLI already installed and authenticated; the plugin has no credentials of its own and fails loudly with an install hint at every seam - plugin load, provider selection, the model picker, and individual requests - rather than surfacing a raw process error. Each native Claude Code process runs in its own process group so a cancelled Hermes request reliably kills the whole underlying process tree, including the Node child behind the CLI, on POSIX and Windows alike; this is validated by CI on Linux, macOS and Windows. Because the underlying native CLI can attempt extra generations even when told not to, the plugin adds a request-scoped loopback relay that forwards only the first Messages API request per turn and rejects any further attempts locally, so Hermes always receives exactly one completed response with accurate usage and stop-reason data. Truncated streams or upstream HTTP errors are still surfaced as failures. Install through the Hermes plugin catalog, directly from GitHub to track main, or by manual clone into the plugins directory, then select the provider from hermes model.
