⚠ This skill is no longer available upstream. Our re-check on Aug 10, 2026 couldn't find it any more (repo unreachable/deleted). The test below is what we measured on Jul 20, 2026 and we're leaving it up as a record — but there is nothing left to install, so we've removed the command.
Built the same 3-slide hero-stat deck twice with python-pptx, naive versus the skill's craft rules, then measured with the skill's own word-budget script: density fell from 38 words/slide (max 58) to 8 (max 18), and the hero stat rendered its unit glyph at 55% of the numeral instead of a pasted-on full-size percent. Every helper script is inline in SKILL.md so nothing external can break, though the file ships with a UTF-8 BOM before its frontmatter and the automated LibreOffice QA render needs soffice, which was absent so only the manual fallback was available.
Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works
- Installs cleanly 4/5
- Triggers reliably 5/5
- Output vs. baseline 8/10
- Docs & honesty 5/5
What Deck DNA does
A python-pptx method for producing slide decks that match your real client or brand decks instead of a generic template: extract design DNA from approved decks, calibrate a per-slide word budget, build fresh with hero-stat and chaptering craft rules, then run a render-QA pass. Triggers when the deliverable is a PPTX that needs to look on-brand rather than templated.
How to install Deck DNA
Nothing to install: the source repository no longer has this skill. If the author brings it back, our daily re-check will pick it up and the command will reappear here.
Commands — how to trigger Deck DNA
-

Extract the design DNA from these approved slides and reuse it -
Make this PPTX look on-brand instead of like a generic template
Frequently asked questions
- Is the Deck DNA skill free?
- Yes. The skill itself is free from opitaru-sys/deck-dna. SkillProof publishes the install command and an independent test verdict at no cost.
- Does Deck DNA work with Claude Code?
- We tested it with Claude Code 2.x (agent harness) on Jul 20, 2026. Verdict: Tested · Works. Built the same 3-slide hero-stat deck twice with python-pptx, naive versus the skill's craft rules, then measured with the skill's own word-budget script: density fell from 38 words/slide (max 58) to 8 (max 18), and the hero stat rendered its unit glyph at 55% of the numeral instead of a pasted-on full-size percent.

- What is the Deck DNA SkillProof Score?
- 8.8/10 — installs cleanly 4/5, triggers reliably 5/5, output vs. baseline 8/10, docs & honesty 5/5.
- How do I install Deck DNA?
- 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 Deck DNA 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.
