Copilot skill

deckforge includes a skill for GitHub Copilot (the Copilot CLI and the GitHub Copilot app). With it, Copilot builds a deck from a short brief:

1. It plans a storyline from your topic, audience, goal and duration.
2. It writes deck.yaml using the live template catalogue (deckforge templates --json).
3. It checks the deck with deckforge build --json and fixes issues until the build is clean.
4. It measures every slide at 1280×720 to find text that overflows or is clipped, and overlays that cover text.
5. It opens the deck in deckforge edit so you can review it.

If you ask, it can also export the approved deck as an editable PowerPoint file.

Install

deckforge skill install-copilot

Option	Effect
(none)	Installs to $COPILOT_HOME/skills/deckforge, or ~/.copilot/skills/deckforge if COPILOT_HOME is not set
--dest <dir>	Installs to another skills folder, for example <repo>/.github/skills
--force	Replaces a folder that the command did not create
--replace-build-presentation	Also removes the older build-presentation skill

Run the command again to update the skill. Then start a new Copilot session and run /skills to check that the skill is loaded.

Example prompts

• "Create a 20-minute deck for engineering managers on release safety; the goal is to agree on one release gate."
• "Restyle these notes into a deckforge deck, in French, with the build theme."
• "Add a lifecycle slide after the concept map and check the layout."
• "Turn the approved deck into an editable PowerPoint."

The skill's files are listed in skills/deckforge.

With the deck tools

The skill writes deck.yaml with the CLI. When a session also has the deckforge mcp tools, for example a conversation continued from the editor, Copilot edits that deck through the tools instead. An open editor then shows each change as it happens.
