Description
Create professional, consultant-grade PowerPoint presentations from scratch using MckEngine (python-pptx wrapper) with McKinsey-style design. Use when user asks to create slides, pitch decks, business presentations, strategy decks, quarterly reviews, board meeting slides, or any professional PPTX. AI calls eng.cover(), eng.donut(), eng.timeline() etc — 67 high-level methods across 12 categories (structure, data, framework, comparison, narrative, timeline, team, charts, images, advanced viz, dashboards, visual storytelling), consistent typography, zero file-corruption issues, BLOCK_ARC native shapes for circular charts (donut, pie, gauge), production-hardened guard rails for spacing, overflow, legend consistency, title style uniformity, dynamic sizing for variable-count layouts, horizontal item overflow protection, chart rendering, and AI-generated cover images via Tencent Hunyuan 2.0 with professional cutout, cool grey-blue tint, and McKinsey-style Bézier ribbon decoration.

常见崩坏模式（每次生成前必读，先于 HARD RULES）
> 告诉 AI 要做什么效果一般，告诉它前人最容易在哪里塌效果更好。 > 以下三种反模式均已在真实执行中被验证，每次必须主动警惕。
反模式 1：口头宣布"门禁通过"（最常见）
错误做法： > 「S4 QA 共 7 个 errors，判断均为 engine 设计行为，门禁通过，进入 S5」 问题所在：passed 是由 AI 口头判断的，不是由程序派生的。无论理由多充分，这句话都是 AI 在给自己写完成证书。 正确做法： • 执行 python references/scripts/gate_check.py <pptx路径> <项目目录> • 读取 <项目目录>/gate_result.json • 只有 gate_result.json 中 "passed": true 时，才能进入 S5 • 如果 "passed": false，修复 user_code_errors 列表中的问题，重新渲染，再次执行 gate_check ---
反模式 2：S3 门禁"脑子里过一遍"就算通过
错误做法： > 「S3 内容门禁预检：API 格式正确，字数在限制内，通过，进入 S4」（没有执行任何代码） 问题所在：今天真实发生的 3 个 API 格式错误（four_column/matrix_2x2/executive_summary 参数格式），靠脑子过是过不出来的，必须靠代码检查。 正确做法： • 执行 python references/scripts/gate_check_s3.py <content.json路径> <项目目录> • 读取 <项目目录>/gate_s3.json • 只有 "passed": true 时，才能进入 S4 • 如果有 fail 项，修正 content.json，重新执行 gate_check_s3 ---
