Open the HTML documents of the user's workspace (slide decks, Reveal.js decks, reports, pages) in the HTML Deck visual editor to edit text, restyle, move blocks, add effects and present, saving in place; and act on the review notes ("AI Feedback") the user pinned there. Use when the user wants to edit, tweak, present or review an HTML deck/report/page visually, mentions HTML Deck, or asks to apply the feedback or notes left on an HTML document.
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
# HTML Deck
HTML Deck is a local editor for the workspace's HTML files. The user edits in the browser; you start
the editor and act on the notes they leave. A save patches the file only where it changed.
## The launcher
The plugin root is two folders above this file (`<this skill's folder>/../..`); Claude Code also
sets it as `${CLAUDE_PLUGIN_ROOT}`. The launcher runs the plugin's own copy with any Python ≥ 3.11,
nothing to install:
- macOS / Linux, and Git Bash on Windows: `sh "<plugin root>/scripts/htmldeck-run"`
- Windows PowerShell: `& "<plugin root>\scripts\htmldeck-run.cmd"` (the `&` is required to run a
quoted path)
- Windows cmd.exe: `"<plugin root>\scripts\htmldeck-run.cmd"`
Below, `RUN` stands for that command. Exit code 127 means no Python 3.11+: pass on the install hint
it prints.
## Open the editor
1. The workspace is the project folder the user works in: `--root "<workspace>"`. Add
`--file <path>` (relative to the workspace) to open one document first: the file the user
named, or the argument of `/htmldeck <file>`. With neither, start without `--file`.
2. Start it in the background — the server runs until stopped:
…Read the whole file at its exact version.
How to install
mdr add avis309/html-deck/open@sha256:d842fb81aa5dcb06The line at the top of this page pins the label git:20261010.960ee6b, 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.
