Open plans and HTML artifacts in a local browser canvas where the human annotates elements, chats, and approves or requests changes without leaving the page. Use when presenting a plan for review, or when feedback like "move this, change that" is easier pointed at than typed.
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
# Plan Canvas Review loop for plans and visual artifacts: you write the artifact, the human reviews it in the browser — annotating the exact element they mean, chatting, and delivering an **Approve plan / Request changes** verdict — while you block on a single CLI call that returns their feedback as JSON. Inspired by [lavish-axi](https://github.com/kunchenguid/lavish-axi); rebuilt ECC-native around the `/plan` confirmation gate, with zero dependencies. ## When to Use - You just wrote a plan artifact (`.claude/plans/*.plan.md` from `/plan`) and need the CONFIRM/approve decision — the canvas verdict replaces a typed "yes/proceed". - The user should *point at* what to change: reviewing designs, comparisons, reports, or any local `.md` / `.html` artifact. - The user asks for `/plan-canvas`, a visual review, or "open it in the browser". Do NOT use for: code review of diffs (`/code-review`), running web apps, or remote URLs. The canvas serves local artifact files only. ## How It Works Invoke the CLI as `ecc-plan-canvas` — the bin shipped by the `ecc-universal` package (on PATH after a global/plugin install; `node "$CLAUDE_PLUGIN_ROOT/scripts/plan-canvas.js"` …

How to install
mdr add affaan-m/ecc/plan-canvas@sha256:45b208f8551ccc37The line at the top of this page pins the label git:20260918.c752aac, 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.
