Use when adding or changing a Canvas Agent tool (canvas_* / workspace_node_* in src/main/agent/tools/). Covers the two registration surfaces, the ZodObject trap, the tool-name compatibility contract, defer_loading, and the execute-class security gate.
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 Agent Tool An ordered procedure. Gives the SEQUENCE and the landmines; FACTS live in the sources it points to — do not restate them here. ## Steps 1. **Snapshot the registry first.** `node apps/canvas-workspace/harness/tools/describe-canvas.mjs` — see the current 45+ tools, the naming conventions per file, and whether your name collides (duplicate names are a hard error there). Note: describe-canvas checks NAMES only — it does NOT verify the global-chat surface (landmine 3 below), so passing it is necessary, not sufficient. 2. **Implement the tool** in the matching per-capability module under `src/main/agent/tools/` (nodes/edges/sessions/terminals/… — match your capability's siblings' shape: `name`, `description`, zod `inputSchema`, `execute`). …

How to install
mdr add hua-bang/pulse-agent/add-agent-tool@sha256:22c96cc4353ac3e3The line at the top of this page pins the label git:20260711.2153867, 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.
