P1 Home Variable Remains Literal

The MCP config writer preserves ${HOME}/.graphnosis/mcp.sock as a literal argv value, and stdio servers launched directly do not receive shell expansion. Unless the relay explicitly expands this syntax itself, the installed server cannot find the user's socket even though installation reports success; the value is also not portable to Windows.

hermes-agent interpolates ${VAR} placeholders in MCP server config before spawn (tools/mcp_tool.py, "Recursively resolve ${VAR} placeholders"), so on macOS/Linux ${HOME} resolves to the real socket path — this matches the convention the other Graphnosis surfaces already use (the relay's own README and the prior catalog preset). You're right that it's not robust on Windows, where HOME is typically unset and the placeholder would stay literal. That's a pre-existing, cross-surface gap rather than something specific to this PR; the proper fix is to have @graphnosis/mcp-relay default to os.homedir()/.graphnosis/mcp.sock when no path arg is given, which I'm tracking on the relay package. Keeping ${HOME} here for consistency with the existing providers.

Update: the relay fix has landed. @graphnosis/mcp-relay@1.0.3 (published) now expands a leading ~ and ${HOME}/$HOME itself via os.homedir() (and defaults to ~/.graphnosis/mcp.sock when no path arg is given), so the socket path resolves correctly even when the host spawns the server without a shell — including on Windows where HOME is unset. The ${HOME} value written here is therefore portable once users are on relay ≥1.0.3.

P1 Local Discovery Misses Description Key

When a local graphnosis plugin directory is discovered, the provider metadata falls back to the bare name because Graphnosis is absent from the known-provider map. MemoryProviders therefore looks up t("graphnosis") instead of this new memory.providers.graphnosis key, so the card displays only graphnosis rather than the added description.

Note: If this suggestion doesn't match your team's coding style, reply to this and let me know. I'll remember it for next time!

Good catch — fixed in 847ed5b. graphnosis was missing from the KNOWN_PROVIDERS map in src/main/installer.ts (and the remote-mode map in src/main/ssh-remote.ts), so discovery fell back to the bare name and the card looked up t("graphnosis") instead of this key. Added graphnosis: { description: "memory.providers.graphnosis", envVars: [] } to both.
