A source-level walkthrough of OpenSlide's four MCP tools, backed by a real stdio recording and an embedded five-page deck built through the same agent workflow.

A source-level look at the small authentication patch, token-file wrapper, and fail-closed build path that let an existing Open Design MCP client talk securely to its daemon.

The code-relay-mcp concept evolved into graphify-plugin-handoff — a Graphify embedded plugin that implements the GraphifyPlugin trait for cross-session agent state handoff, eliminating the standalone MCP server in favour of in-process integration with Graphify Core.

Graphify's plugin system partitions into embedded v1 traits, in-development review pipeline, and planned MCP-native external layer. Core implements synchronous workspace routing with GraphifyPlugin trait, WorkspaceContext, and GraphUpdateEvent kinds. The external layer remains a roadmap for third-party plugins.

Tapedeck is a Rust proof of concept for turning declarative .roll scripts into repeatable terminal recordings. This first look covers the VHS/native engine split, XDG configuration, dry runs, and the small TUI that makes CLI demos reproducible.
