Opens a Markdown file or folder in the browser as GitHub will show it, drawn by GitHub's own renderer, refreshing as the file changes. A folder opens GitHub-style, its file list beside its README. Readers comment on any line and send the comments to Claude in one batch, and Claude fixes the doc and replies on each. Use when the user asks to see, show, open, view or preview a doc ("show me the brief", "open the plan", "preview the spec"), or says "go through my comments". Also owns when a phase…
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
# markdown-preview Show a doc the way GitHub will, while it's still on disk, and let the reader comment on it in place. GitHub turns the Markdown into HTML, so what the reader sees here is what they'll see in a PR or on the repo. The page refreshes each time the file is saved, so a comment can be fixed while the reader watches. Whatever changed since the reader last sent comments is marked: added text in green, removed text struck through in red. An edited paragraph that only gained or only lost words shows once with the change marked in place; one that did both shows old above new, with just the changed words picked out. So they can check every edit made in answer, not just the line they commented on. ## Pick what to open - **"The plan", "the plan folder"**: the current feature's plan folder, scoped to it (below). Its page shows `README.md`, the read-order index, beside a file list in that same order. Find the folder the way the pipeline does (see `CLAUDE.md`'s "Finding the current feature's plan folder"), and ask only if it's still ambiguous. - **"The brief", "the spec", "the plan's tasks"**: that file in the plan folder, scoped to the folder. …

How to install
mdr add mattbrailsford/umbraco-devkit/markdown-preview@sha256:69607227adf0af2cThe line at the top of this page pins the label git:20261106.fc908f2, 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.
