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: Tested · Works
Score: 9.6/10
Tested: Jul 15, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · 1db16ab

Rendered a real 9-slide .pptx for a board pricing recommendation and verified it with python-pptx: native embedded charts, a real Owner/Action/Outcome table, and working per-source hyperlinks -- a genuine IEA URL kept its hyperlink while a fabricated 404 URL had its link silently stripped (server printed 'NOTE: source URL hidden (HTTP 404)'), exactly as SKILL.md claims. Company-logo auto-download from logo.dev also worked live, caching a real stripe.com.png.

What MBB Decks does

Generates real .pptx consulting decks (McKinsey/Bain/BCG house style) from a JSON spec, enforcing a ghost-deck-first storyline pass, action-title rules, MECE bullets, a mandatory recommendation action table, and citation discipline with live-verified hyperlinks. Triggers on requests for board prereads, executive readouts, market-entry or due-diligence decks, or any request for a real .pptx rather than a markdown outline.
