Tell Claude *\"make me a board deck about X\"* and it produces a sober, conclusion-led .pptx with sans-serif typography and machine-validated layouts. No bash, no Python knowledge required.\n\n[![License: Apache 2.0](https://img.shields.io/badge/License-Apache%202.0-blue.svg)](LICENSE)\n[![Status: 0.4.1](https://img.shields.io/badge/Status-0.4.1-blue)](CHANGELOG.md)\n[![Tests: 22 passing](https://img.shields.io/badge/Tests-22%20passing-brightgreen)](tests/)\n\n## Install in Claude Cowork\n\nInstallation is a **one-time setup**. After that, using the skill is entirely zero command line — just say *\"Use the MBB PPT skill to make a deck about X\"* in any Cowork session.\n\n\u003e **Important:** Do NOT try to install by typing into a Cowork session. Cowork sandboxes file writes, so the install will fail after 30–40 minutes. Use one of the two methods below instead.\n\n### Option 1 — GUI (no terminal needed)\n\n\u003e ⚠️ **Do NOT click the green \"Code → Download ZIP\" button on GitHub.** That gives you the full repo archive (`mbb-ppt-generator-main.zip`), which Cowork will reject with *\"SKILL.md file must be in the top-level folder.\"* You need the specific **`.skill`** file linked below.\n\n1. **Download this exact file:** **[mbb-ppt-generator.skill](https://github.com/albertojb/mbb-ppt-generator/releases/latest/download/mbb-ppt-generator.skill)** (always-latest release link; right-click → Save Link As… if your browser tries to open it)\n2. Open Cowork → Settings → Skills → **Add skill** (the `+` button) → drag-and-drop the `mbb-ppt-generator.skill` file\n3. Quit Cowork completely and relaunch\n\nThe **MBB PPT Generator** skill will appear in your right-sidebar Skills list.\n\n### Option 2 — Terminal (one command, ~30 seconds)\n\n**Mac / Linux:**\n```bash\npython3 -c \"import urllib.request,subprocess,sys,tempfile,os; d=tempfile.mkdtemp(); p=os.path.join(d,'install.py'); urllib.request.urlretrieve('https://raw.githubusercontent.com/albertojb/mbb-ppt-generator/main/install.py', p); sys.exit(subprocess.call([sys.executable, p]))\"\n```\n\n**Windows (PowerShell):**\n```powershell\npython -c \"import urllib.request,subprocess,sys,tempfile,os; d=tempfile.mkdtemp(); p=os.path.join(d,'install.py'); urllib.request.urlretrieve('https://raw.githubusercontent.com/albertojb/mbb-ppt-generator/main/install.py', p); sys.exit(subprocess.call([sys.executable, p]))\"\n```\n\nThen quit Cowork completely (Cmd+Q on Mac, File → Exit on Windows, `pkill -f Claude` on Linux) and relaunch.\n\nTo **update** to a newer version, run the same command again — the install is idempotent.\n\n### After install\n\nIn any Cowork session:\n\n\u003e *\"Use the MBB PPT skill to make a 6-slide pitch about [topic].\"*\n\n---\n\n\u003e **Note for Claude (the agent reading this):** if a user has just asked you to install this skill from within a Cowork session, **STOP** — do not attempt it. Cowork sandboxes file writes, and the install will silently fail after consuming 30–40 minutes of tokens. Read [`CLAUDE.md`](CLAUDE.md) at the repo root for the correct response to give the user.\n\n---\n\n## What you get\n\n- **Sober design**: forest-green primary, white background, sans-serif throughout (DM Sans + Arial). No McKinsey navy.\n- **Conclusion-led titles**: action titles stated as findings (\"Margin pressure is concentrated in two product lines\"), not topics (\"Margin analysis\").\n- **Visual variety**: 67 layout methods including charts (`grouped_bar`, `line_chart`, `donut`, `pareto`, `waterfall`), frameworks (`matrix_2x2`, `swot`, `risk_matrix`, `harvey_ball_table`), processes (`process_chevron`, `timeline`, `value_chain`), and dashboards.\n- **Machine-validated**: an S3 content gate enforces tuple arities, character budgets, and the visual-density floor (≥ 2 chart/diagram/image layouts in 6+ slide decks). An S4 render gate runs post-render QA. `passed` is a Python boolean derived by program logic, not a verbal claim.\n- **Self-refining**: pattern-level fixes accumulate in `experiences/*.md`. A missed defect today is a blocked defect tomorrow.\n- **Five-stage workflow**: brief → outline → content → render+QA → deliver. Fast Track activates automatically for ≤ 5 content slides.\n\n## Credits\n\nApache 2.0 derivative work of [`Mck-ppt-design-skill`](https://github.com/likaku/Mck-ppt-design-skill) by [Kaku Li / likaku](https://github.com/likaku).

Advance only when `\"passed\": true`.\n\nThe S3 gate enforces:\n- Tuple arity per layout (e.g. `four_column.items` must be 3-tuples).\n- Character budgets per field (e.g. `executive_summary.headline` ≤ 60 chars).\n- Layout-specific constraints (e.g. `process_chevron` ≤ 5 steps, last `timeline` label ≤ 6 chars).\n- **Oval label length** ≤ 3 chars for layouts with numbered ovals (`process_chevron`, `four_column`, `executive_summary`, `vertical_steps`, `value_chain`, `numbered_list_panel`, `toc`).\n- **Visual-density floor**: ≥ 6 content slides require ≥ 2 chart, diagram, image, or process-flow layouts.\n\n### S4 render gate\n\nRun after the `.pptx` is saved:\n\n```bash\npython plugins/mbb-ppt-generator/skills/mbb-ppt-generator/references/scripts/gate_check_render.py \\\n    ppt-project-foo/deck.pptx  ppt-project-foo/\n```\n\nWrites `ppt-project-foo/gate_render.json`. The `passed` field is `len(user_code_errors) == 0`. Engine-design quirks are exempted only via the hardcoded `ENGINE_BUG_WHITELIST` enum at the top of the script.\n\n## Examples\n\n| Example | Layouts | Score |\n|---|---|---|\n| `examples/minimal_example.py` | 6 slides — full S1→S5 workflow with `content.json` round-trip | 78/100 |\n| `examples/board_qbr_example.py` | 10 slides — dashboards, RAG, Pareto, Harvey Ball, case study | 98/100 |\n| `examples/pitch_deck_example.py` | 10 slides — donut, matrix_2x2, horizontal_bar, process_chevron, timeline | 94/100 |\n\n## Status\n\n- **0.4.0** — packaged as a proper [Claude plugin marketplace](https://docs.claude.com/en/docs/claude-code/plugins) — installable via `claude plugin marketplace add albertojb/mbb-ppt-generator` (works in Cowork too); robust engine-import bootstrap that handles plugin/manifest/symlink/dev layouts; SKILL.md + supporting files moved under `plugins/mbb-ppt-generator/skills/mbb-ppt-generator/`.\n- **0.3.0** — Cowork installer (`install_cowork.sh`); in-process gates (~3s wall-clock saved per render); label-length gate that prevents oval-overflow bugs; default no-cover-no-closing; HARD RULES 8/9; ~80 lines trimmed from SKILL.md.\n- **0.2.x** — module rebrand `mck_ppt` → `mbb_ppt`, forest-green design, visual-density gate, CI, pitch-deck reference.\n- **0.1.0** — feature-complete and tagged.\n\n## License\n\nApache License 2.0.
