Use when adding a new canvas node capability to Pulse Canvas (apps/canvas-workspace). Plugin nodes are the default path; host types are the documented exception. Covers both paths' exact touch points and the landmines (union/factory desync, dispatch fallthrough, agent-tool contract surface).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Add a Canvas Node An ordered procedure for adding a new node capability. Gives the SEQUENCE and the landmines; FACTS live in the knowledge docs it points to — do not restate them here. ## Step 0 — plugin is the default; host type is the exception **Decided (owner, 2026-07-08):** new node capabilities are plugin nodes (Step 1) by default. Host-type extension (Step 2) is reserved for a node that needs genuine **main-process integration the plugin capability registry doesn't cover** — specifically a persistent session/IPC channel (the reason `terminal`/`agent` are host types: PTY sessions are an open, ongoing channel, not a request/response call) or a dedicated storage-migration path. The plugin capability model (`read`/`write`/`actions`) is request/response — it does not fit a node that needs to hold an open channel. If you're building a content/display/interaction node (the large majority of future node needs), use Step 1. If you hit a case that's genuinely ambiguous against the criterion above, that's new evidence — say so explicitly in your PR rather than defaulting to host type quietly; the criterion may need tightening. …

How to install
mdr add hua-bang/pulse-agent/add-canvas-node@sha256:665fe159d944cd8bThe line at the top of this page pins the label git:20261010.bc65cd1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
