Is the Deckify skill free?

Yes. The skill itself is free from zakelfassi/htmlify. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Deckify SkillProof Score?

8.8/10 — installs cleanly 4/5, triggers reliably 5/5, output vs. baseline 10/10, docs & honesty 3/5.

How do I install Deckify?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Deckify with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Test report

Verdict: Works with setup
Score: 8.8/10
Tested: Jul 15, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · a5dc1ea

Built a real 3-slide deck following the skill's DOM contract and ran the actual bundled validator against it -- 'valid, 0 errors, 0 warnings, profile: deck' -- but the exact validator command the skill body tells you to run is broken as written (npm bin/package name mismatch); the npx fallback works once you add the missing -p flag.

What Deckify does

Deckify turns source material into a single self-contained HTML file with a presentation-deck mode (keyboard nav, speaker notes, run-of-show) and a downloadable guide/print mode, following a strict validator-enforced DOM contract. It triggers when a user wants a presentable deck, speaker notes, run-of-show, demo plan, or PDF/guide output rather than a flat markdown answer.

How to install Deckify

git clone https://github.com/zakelfassi/htmlify
mkdir -p ~/.claude/skills
cp -r htmlify/skills/deckify ~/.claude/skills/deckify

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.
