Add or change a Pulse Canvas capability that must be available through structured agent tools and the pulse-canvas CLI. Use for cross-workspace Capability Runtime changes spanning apps/canvas-workspace, packages/canvas-cli, or packages/cli, including new live read, operate, or unsafe application actions.
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 Canvas Capability Make the Capability Runtime the single behavior boundary. Expose that capability through native tools and CLI adapters without duplicating domain logic, policy, transport, or error handling. ## Workflow 1. Define the contract before editing. - State the user-visible action and why a persisted-store command is insufficient. - Choose a stable dotted name such as `canvas.nodes.archive`. - Define the Zod input, JSON-serialisable output, stable error codes, and `read`, `operate`, or `unsafe` risk. - List the intended consumers: Canvas Agent, Pulse Agent, external Codex/Claude agents, or a subset. 2. Read the owners. - Read root `AGENTS.md`, `harness/README.md`, and `harness/validate/validation.yaml`. - Read `apps/canvas-workspace/AGENTS.md` and its local validation file. - Read `packages/canvas-cli/AGENTS.md` and its local validation file. - Read `packages/cli/AGENTS.md` when changing Pulse Agent tool registration or descriptions. - Inspect sibling definitions under `apps/canvas-workspace/src/main/runtime/capabilities/` and the current policy in `capabilities/index.ts`. …

How to install
mdr add hua-bang/pulse-agent/add-canvas-capability@sha256:5c5b96d32cbe06b8The line at the top of this page pins the label git:20260810.46bae72, 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.
