# CN Client Investigation Skill

**中国大陆客户调查分析 — 文字与数据双重保证**

Use this skill when the target company is a China-market entity and the deliverable (MD / PPTX / Excel) must be free of Chinese character-level typos and based on verifiable Chinese-market data sources.

## Why this skill exists

实测 2026-04-18 寒武纪 (Cambricon 688256.SH) 分析中，MiniMax-M2.7 在 pptxgenjs `\uXXXX` escape 序列里把"寒武纪"打成了"宽厭谛79"，把"净利/财务/亏损"打成"洁利贜务贜损"。根因是中文罕见词的 token 级 BPE 切块 + 字符级错位。这个 skill 提供两道防线：

1. **Pre-computed Chinese lexicon**：关键公司名 / 行业术语 / 财务词 **先写死在本 skill 的 reference 文件里**，agent 生成 slide JS 时直接 `require('./references/cn-lexicon.js')` 读取，不经过模型逐字符生成。
2. **UTF-8 literal over Unicode escape**：JS 源码里 `slide.addText("寒武纪科技")` 而不是 `slide.addText("\u5BD2\u6B66\u7EAA\u79D1\u6280")`。literal 中文走 UTF-8 字节不经过 `\uXXXX` 解码路径，绕开 MiniMax 的主要 typo 通道。

## Mandatory guardrails

### Rule 1 — No `\uXXXX` escape for Chinese text (text accuracy)

**In every slide-NN.js / markdown / Python code you emit, write Chinese characters as UTF-8 literals. NEVER encode Chinese as `\uXXXX` escape sequences.**

```javascript
// ✅ CORRECT — UTF-8 literal
slide.addText("寒武纪科技深度分析", { fontSize: 44, fontFace: "Microsoft YaHei" });

// ❌ WRONG — Unicode escape, MiniMax token-level typo risk
slide.addText("\u5BD2\u6B66\u7EAA\u79D1\u6280...", { ... });
```

All source files must be saved as **UTF-8 no BOM**. The `write` / `edit` tools accept raw Chinese fine; do not pre-encode to `\uXXXX` thinking it's "safer" — it is the opposite.

### Rule 2 — Lexicon lookup before typing key terms (text accuracy)

Before emitting any of these classes of Chinese terms in code, look them up in `references/cn-lexicon.js`:

- Target company full name (e.g. 寒武纪科技、海光信息、摩尔线程智能科技)
- Section headers (公司概览、财务分析、竞争格局、估值分析、投资结论、投资亮点、风险分析)
- Financial line items (营业收入、归母净利润、扣非净利润、毛利率、净利率、研发费用、经营现金流)
- Investment recommendations (增持 / 中性 / 减持 / 买入 / 卖出 / 积极关注)
- Market / product terms (智算中心、AI加速、国产替代、CUDA兼容、实体清单、港交所递表)

If the term you need is not in the lexicon, add it to the lexicon first (one commit), then reference it. Don't type Chinese from memory in a `\uXXXX` form. See [references/cn-lexicon.js](references/cn-lexicon.js).

### Rule 3 — Cover page English primary, Chinese secondary (text safety shield)

Cover slides MUST use the English company name as 44pt hero title and Chinese name as ≤28pt subtitle. English ASCII has zero escape-typo risk; the Chinese subtitle is shorter and easier to sanity-check.

```javascript
slide.addText("Cambricon Technologies", { fontSize: 44, fontFace: "Georgia", bold: true });       // 大字英文
slide.addText("寒武纪科技深度分析", { fontSize: 26, fontFace: "Microsoft YaHei" });                   // 小字中文
```

### Rule 4 — Data source hierarchy (data accuracy)

中国公司数据 MUST come from this tier, in order. Only drop to lower tier if higher tier returns empty / 402 / 403:

| Tier | Source | MCP tool / method |
|------|--------|-------------------|
| T1 — 交易所/监管披露 | 巨潮资讯 (cninfo.com.cn) 招股书 / 年报 / 季报 PDF 原文 | `web_fetch` on cninfo URL, parse PDF text |
| T1 — 盘面数据 | Tushare Pro | `aigroup-market-mcp__company_performance`, `aigroup-market-mcp__stock_data`, `aigroup-market-mcp__basic_info` |
| T2 — 公司公告 | 上交所 / 深交所 / 港交所官网 | `web_fetch` on sse/szse/hkex |
| T2 — 工商信息 | 天眼查 / 企查查（如 MCP 已装）/ 国家企业信用公示系统 | `aigroup-tianyancha-mcp` 或 `web_search` |
| T3 — 第三方数据 | Wind / 同花顺 / 东方财富 / FMP / Finnhub（港股/中概股） | `aigroup-fmp-mcp`, `aigroup-finnhub-mcp` |
| T4 — 公开报道 | 财新 / 21世纪 / 中新社 / 澎湃 / 财联社 | `brave-web-search`, `web_fetch` |

### Rule 5 — Cross-check every hard number + provenance gate (data accuracy, MANDATORY)

Every financial number in the deliverable (营业收入 / 净利润 / 毛利率 / 市值 / 股价 / 融资金额) must be verified by at least **2 independent sources from the tier table above**, OR clearly flagged as "single-source estimate" with the source cited in a page footer caption. If 2 sources diverge by > 5%, report both and pick the more recent; add a footnote.

**Mandatory Phase 5 QA gate** — every deliverable must pass `provenance_verify.py` before being considered shippable. The script scans the analysis markdown for hard numbers (`digit + 亿/万/%/RMB/USD/元/CNY/HKD/M/B`) and confirms every one of them has a matching row in the companion `data-provenance.md` tracking table. Missing provenance → exit 1 → block delivery.

```bash
python3 skills/cn-client-investigation/scripts/provenance_verify.py \
    deliverable/analysis.md \
    deliverable/data-provenance.md
```

**Before shipping, also run in `--strict` mode.** Strict adds two additional checks on top of the baseline substring match:

1. **Estimate-as-T1 smuggling** — if a hard number in `analysis.md` is adjacent to an estimate marker (`~`, `约`, `大约`, `估算`, `approximately`, `est.`, `粗估`, `推算`), the matching `data-provenance.md` row's source column MUST include at least one derivation keyword: `[ESTIMATED]` / `[DERIVED]` / `估算` / `推算` / `derived` / `computed` / `analyst estimate`. Otherwise the gate FAILs with the offending line number. This catches the common pattern where the agent writes `~22.9%` but marks the provenance row with a T1 source like "Tushare Pro income_all" — which looked fine under the baseline substring check but is semantically misleading (the T1 source did not return 22.9%; the agent derived it).
2. **Precision drift (WARN, non-blocking)** — when the same rounded integer + unit appears with multiple precisions in the analysis (e.g. `1.34 元/股` vs `1.340 元/股` vs `1.3 元/股`), the gate emits a WARN so the agent can decide whether the differing precisions are intentional (e.g. pre vs post restatement with footnote) or a typo.

```bash
python3 skills/cn-client-investigation/scripts/provenance_verify.py --strict \
    deliverable/analysis.md \
    deliverable/data-provenance.md
```

Non-strict mode behavior is unchanged — `--strict` is additive and opt-in.

Every banker deliverable MUST include a `data-provenance.md` file at the deliverable root. Use the template under `references/data-sources.md` as the starting shape. Fill in one row per hard number with: 指标 / 数值 / 单位 / 期间 / Tier / 源 / URL 或工具 / 取数时间 / 交叉验证状态.

### Rule 6 — No fabrication on missing data (data accuracy)

If a needed data point cannot be fetched (MCP returns error, web blocked, document inaccessible):

- **DO NOT** invent a plausible-looking number
- **DO** label the cell / chart / page-section as "数据不可得" / "N/A (source unavailable)" with a footnote explaining the attempted source
- **DO** proceed with the rest of the analysis — missing data doesn't block the deck

Historical `micro_probit` / `panel_var_model` style illustrative data is NOT appropriate for China banker deliverables — those tools belong to the lab bundle and produce demonstration output only.

### Rule 7 — Self-verify deck text before delivery (typo detection, MANDATORY GATE)

**Typo detection is NOT an optional step — it is a compile-time gate. A pptx that has not passed `cn_typo_scan.py` is NOT a shippable deliverable.**

The canonical way to enforce this is to base `slides/compile.js` on the provided template:

```
references/compile_with_typo_gate.template.js.txt
```

Copy it to the deliverable's `slides/compile.js` (rename the `.txt` suffix off), adjust `SLIDE_COUNT` / `OUTPUT_PATH` / `THEME` at the top, then `cd slides && node compile.js`.

**Why the `.txt` suffix in the plugin bundle**: the template contains a `child_process.spawnSync` call to invoke the Python scanner, which OpenClaw's install-time safety scanner flags as a dangerous runtime pattern. Keeping the template as `.js.txt` under `references/` tells the scanner this is documentation, not executable plugin code. At use time, you always copy it into your own deliverable's `slides/` directory and strip the `.txt` — at that point it is your own script, outside the plugin trust boundary. The template:

1. Standard pptxgenjs compile loop (require slide-01.js … slide-NN.js, call `createSlide(pres, theme)`, `writeFile`)
2. Spawn `python3` with the skill's [`cn_typo_scan.py`](scripts/cn_typo_scan.py) against the newly-written pptx's extracted text
3. If scan exit is non-zero, node `process.exit(1)` — the pptx is NOT considered delivered until the offending `slide-NN.js` files are fixed and the compile is re-run

If you cannot use the template verbatim (e.g. custom compile pipeline), you MUST still run the equivalent gate after every `writeFile`:

```bash
python3 -c "from pptx import Presentation; p = Presentation('deck.pptx'); [print(para.text) for s in p.slides for sh in s.shapes if sh.has_text_frame for para in sh.text_frame.paragraphs if para.text.strip()]" > /tmp/deck.txt
python3 skills/cn-client-investigation/scripts/cn_typo_scan.py /tmp/deck.txt  # exit 0 = ship, exit 1 = abort
```

`cn_typo_scan.py` greps for these red-flag patterns (all observed in 2026-04-18 runs or confirmed on the broader `\uXXXX` token-drift pattern space):

- Rare character dyads that shouldn't appear in banker prose: 宽厭 / 谛数字 / 洁利 / 贜 / 校虚 / 催化济 / 棒品 / 转映 / 艺瑞 / 调诚
- Chinese chars immediately followed by digits (classic escape truncation symptom): `[一-龥][0-9]`
- CJK Extension A / B / C / D characters (U+3400-U+4DBF, U+20000+) — almost always corruption in banker prose

On scan hit:
1. Read the stderr report — each line gives L<n>, reason, and context snippet
2. Identify the source `slide-NN.js` file containing the offending text
3. Replace the broken Unicode string with the UTF-8 literal fix (preferably via `LEXICON.red_zone.<key>` lookup from [`references/cn-lexicon.js`](references/cn-lexicon.js) — Rule 2)
4. Re-run `node slides/compile.js` — the gate will rescan

Do NOT ship a pptx that has bypassed the gate. Do NOT `--no-typo-scan` your way out of failures.

## Workflow

### Phase 1 — Scope + lexicon load

1. Confirm target: A-share / STAR / ChiNext / 北交所 / 港股 / 中概股 / 非上市独角兽 —— 决定数据源 tier
2. Load / update `references/cn-lexicon.js`:
   - Target company name (中/英/ticker)
   - Top-5 peers (中/英/ticker)
   - Industry specific terms（AI 芯片 / 新能源车 / 创新药 / SaaS）
3. Decide regulator context (证监会 / 香港证监会 / SEC for US-listed ADR)

### Phase 2 — Data collection (按 tier 依次 try，记录 source)

For each required data element (营收/利润/股价/估值/股权结构/管理层/业务线/竞争/风险)：

1. Call T1 MCP (Tushare / 巨潮 fetch). Record raw output.
2. If T1 failed or incomplete, call T2 (交易所官网 / 天眼查). Record.
3. Cross-check: pick any hard number from T1 vs T2 vs T3 — require ≥ 2 agreeing sources or flag.
4. Record source list in `references/data-provenance.md` (update per company) with URL + retrieval timestamp.

### Phase 3 — Analysis synthesis (投行传统维度)

Follow the banker-classical analysis frame (`customer-analysis-pack` skill), enhanced with:

- CN-specific 股权结构 section: 实控人 / 国资 / 员工持股 / 战略投资人 / 解禁时间表
- CN-specific 政策驱动 section: "十四五" / 新基建 / 专精特新 / 国产化替代进度
- CN-specific 监管风险 section: 证监会处罚历史 / 关联交易披露 / ESG 新规

### Phase 3.5 — Raw-data snapshot (MANDATORY from v0.9.0)

**Why**: 2026-04-20 多公司 real-test 发现 MiniMax 在 provenance 的 Source 列里写"Wind (2026-04-17)"、"同花顺 F10"这种**并未安装的工具名称**作为来源 —— 纯捏造。要堵这个洞，agent 在写 analysis.md 之前必须把**真实的 MCP 工具调用结果**存成 JSON 快照，作为审计尾迹。

**三个 CN MCP（插件 `.mcp.json` 已声明依赖）**：

| MCP | 覆盖 | 关键工具 |
|-----|------|---------|
| `aigroup-market-mcp` | 上市公司行情 + 财务 (Tushare) | `basic_info` / `company_performance` / `stock_data` / `index_data` / `finance_news` |
| `PrimeMatrixData` | 上市 + 非上市企业工商 + 司法 + 风险 (启信宝) | `basic_info` / `judicial_info` / `risk_info` / `shareholder_info` / `finance_info` |
| `Tianyancha` | 上市 + 非上市企业基础 + 风险全景 (天眼查) | `companyBaseInfo` / `risk` |

**要求**：在 `<deliverable-dir>/raw-data/` 目录下保存每次 MCP 调用的原始 JSON，文件名格式 `{identifier}-{mcp-short}-{tool}.json`。

**上市公司（有 ts_code，如 002594.SZ / 300750.SZ / 0700.HK）必须包含**：

1. `{ts_code}-aigroup-market-mcp-basic_info.json`
2. `{ts_code}-aigroup-market-mcp-company_performance.json`
3. `{ts_code}-aigroup-market-mcp-stock_data.json`
4. ≥1 企业风险 overlay：`{uscc}-primematrix-basic_info.json`（primary）或 `{uscc}-tianyancha-companyBaseInfo.json`（备用，见下）

**非上市公司（只有 统一社会信用代码 / uscc）必须包含**：

1. ≥1 企业风险 overlay：`{uscc}-primematrix-basic_info.json`（primary）或 `{uscc}-tianyancha-companyBaseInfo.json`（备用）
（aigroup-market-mcp 不适用，可省略）

**强制前置步骤 — 公司名称核验（v0.9.2+）**：非上市公司调 `PrimeMatrixData__basic_info` 之前，**必须先调 `PrimeMatrixData__company_name` 模糊查出精确注册名**。常见的公众名 ≠ 法定名陷阱：

- "字节跳动" 实际内地主体已于 2023 年改名为 **抖音有限公司**
- "京东数科" 后改名 **京东科技控股股份有限公司**
- "滴滴" 的大陆注册主体是 **北京小桔科技有限公司**

用公众名硬调 `basic_info`，PrimeMatrix 返回 `{}` 空对象，下游数据全部空白。`raw_data_check.py` 现在会检测"PM basic_info 无统一社会信用代码"并 FAIL。正确姿态：

```
step 1: PrimeMatrixData__company_name(blur_name="字节跳动")  →  列出匹配实体
step 2: 人工 / agent 选定法定名  →  "抖音有限公司"
step 3: PrimeMatrixData__basic_info(company_name="抖音有限公司")  →  完整工商信息
```

**risk_info 空返回警觉**：PM `risk_info` 若只返回 `{"公司名称": "..."}` 而无 `司法/经营异常/关联风险` 等字段，不等于"企业干净"——可能是 PM API 对该实体无数据返回。banker 交付前需手工再核一次司法公告/行政处罚/失信被执行人库，不能靠 gate 反向证明。

**Tianyancha 当前状态（2026-04+）**：智谱 MCP broker 的 Tianyancha 账户暂停（余额耗尽）。gate 接受已有 snapshot 但不强制 — PrimeMatrixData 目前是唯一实际可达的企业风险 overlay。需要启用 Tianyancha 时充值 + 按 lead-discovery QUICKSTART 注册即可。

**data-provenance.md 要求**：每个 `raw-data/*.json` 文件的文件名 stem 必须在 `data-provenance.md` 的 Source 列至少出现一次 —— 这建立了"MD 里的数字 ↔ 溯源表 ↔ 原始 MCP 调用"的闭环。

**Worked example (BYD 002594.SZ)**：

```
deliverables/byd-20260420/
├── raw-data/
│   ├── 002594.SZ-aigroup-market-mcp-basic_info.json      ← basic_info 返回：公司简介 + 行业 + 上市日期
│   ├── 002594.SZ-aigroup-market-mcp-company_performance.json  ← 营收 / 净利润 / 毛利率 / ROE 时间序列
│   ├── 002594.SZ-aigroup-market-mcp-stock_data.json       ← 近 1 年日线 OHLC + 复权
│   └── 91440300192317458F-tianyancha-companyBaseInfo.json  ← 工商基本信息 + 统一社会信用代码
├── data-provenance.md   （每一行 Source 列写 `aigroup-market-mcp__company_performance` 或对应 raw-data 文件名 stem）
├── analysis.md
├── slides/ ...
└── 比亚迪_deep_analysis.pptx
```

**验证**：`raw_data_check.py`（在 `validate-delivery.py` aggregator 的第 3c 道 gate 自动跑）会确认：
- `raw-data/` 目录存在且至少有 3 个 JSON 文件
- 上市 vs 非上市的工具覆盖满足上述要求
- 每个 raw JSON 文件 stem 都在 provenance 里被引用

**Back-compat**：0.8.x 版本的旧交付物没有 `raw-data/` → 默认模式下 gate 3c 给出 WARN 但不 FAIL；`--strict-mcp` 模式下直接 FAIL。新交付物必须上 raw-data/。

### Phase 4 — Deliverable generation (banker-memo preferred, v0.9.6+)

**PREFERRED ROUTE (0.9.6+): Prompt-driven `banker-memo` skill + `build_outline_deck.py`.**

The `banker-memo` skill dispatches the MiniMax agent through an investment-banker-analyst framework (8-section research memo + content-driven 10-15 slide outline, no fixed page count). Usage:

```bash
# 1. After raw-data/ is populated (Phase 3.5), dispatch banker-memo skill
python3 scripts/banker-memo/scripts/build_banker_prompt.py \
    <ts_code> <name_cn> <industry> <raw_dir> <out_dir> > /tmp/prompt.md
openclaw agent --agent main --thinking high --json --timeout 600 \
    --message "$(cat /tmp/prompt.md)"
# Agent writes analysis.md + slides-outline.md + data-provenance.md

# 2. Compile outline-driven PPT
python3 scripts/cn-client-investigation/scripts/build_outline_deck.py \
    <dir> <ts_code> <name_cn> <name_en>

# 3. Close provenance gaps + validate
python3 scripts/cn-client-investigation/scripts/sync_provenance.py <dir>
python3 scripts/cn-client-investigation/scripts/validate-delivery.py --strict-mcp <dir>
```

Why preferred: 0.9.5 Python-templated `build_deck.py` produced an 8-slide data dashboard — no industry context, no peer benchmarking, no SOTP / 4C's. 0.9.6 prompt-driven path: agent writes banker narrative (14-20 KB analysis) with peer comparison ([EST] tagged), Data Flag self-reporting (e.g. income vs company_performance 0.59pp discrepancy), SOTP valuation scenarios, 4C's credit framework with specific 授信额度 / 期限 / 利率 / 增信 recommendations.

**LEGACY ROUTE (still supported for quick fact-sheets): `build_deck.py`** emits a fixed 8-slide stat-card dashboard. Use only when depth isn't required.

**Both routes share:** pptxgenjs slide compile + cn_typo_scan post-write gate. NEVER use python-pptx for generation (white background / no theming; only permitted for text extraction inside `validate-delivery.py`).

For CN targets, these routes override `ppt-deliverable`'s "MiniMax first" routing — only pptxgenjs compile integrates the compile-time typo gate.

Steps:
1. Write `slides/slide-01.js … slide-NN.js` — each exports `createSlide(pres, theme)`.
2. Copy `references/compile_with_typo_gate.template.js.txt` → `slides/compile.js` (strip `.txt`), set `SLIDE_COUNT` / `OUTPUT_PATH` / `THEME`.
3. `cd slides && node compile.js` — the template's post-write gate runs `cn_typo_scan.py`; if it fails, fix the offending slide-NN.js and recompile.
4. `slides/slide-01.js` cover uses Rule 3 (English hero 44pt + Chinese subtitle ≤28pt).
5. Every `addText` with Chinese content uses the lexicon (`require('./references/cn-lexicon.js')`); do NOT inline-type long Chinese strings.

### Phase 5 — QA (用 `validate-delivery.py` 单入口)

**推荐一条命令跑完六道 gate**：

```bash
python3 ~/.openclaw/extensions/aigroup-financial-services-openclaw/skills/cn-client-investigation/scripts/validate-delivery.py \
    --strict --strict-mcp --style \
    /path/to/deliverable_dir
# exit 0 → 全部 PASS；--strict-mcp 下还要求 source 列有 MCP-tool / 官方披露 anchor 且 raw-data/ 齐全
# exit 1 → 至少一道 gate 失败，stderr 指出是哪道 + 具体行号 / 原因
```

Aggregator 自动按文件名 find 并调度：
- `*intelligence*.md` → `verify_intelligence.py`（跨插件引用 lead-discovery 的 cn-lead-safety）
- `*.pptx` → 自动 extract text + `cn_typo_scan.py`
- `*.pptx` + `data-provenance.md` → `slide_data_audit.py`（v0.6.0 起：PPT 上每个硬数字必须有 provenance 行支撑；捕获 Phase 4 手改 slide-NN.js 后 provenance 未同步更新的漂移）
- `analysis.md` + `data-provenance.md` → `provenance_verify.py`（`--strict` 开启 estimate-as-T1 smuggling 检测 + 精度漂移 WARN）
- `data-provenance.md` → `source_authenticity_check.py` (**NEW v0.9.0**：扫 Source 列，拦 Wind / 同花顺 等未安装工具的伪造标注；`--strict-mcp` 下非 MCP / 非官方披露全部 FAIL)
- `<dir>/raw-data/` → `raw_data_check.py` (**NEW v0.9.0**：校验 Phase 3.5 的 MCP 调用快照 + 上市 vs 非上市覆盖 + provenance 引用闭环；`--strict-mcp` 下缺 raw-data/ 直接 FAIL)
- 可选 `--style` → `style_scan.py --warn-only` 对 analysis.md 扫货币/期间/日期/YoY 术语一致性（非阻塞）

Debug 单 gate 时仍可分别跑（见各自脚本）。额外手动 QA：
1. Sensitive items（未披露财务细节 / 估值倍数）must 标 "估算" / "illustrative" with caption if not from T1-T2 source.
2. Final deck 加 "已知缺口 / 数据置信" 汇总 section 到 appendix.

**强烈建议：validate-delivery PASS 之后，交付客户之前，再跑一次 `data-quality-audit` skill**（在 paired plugin `aigroup-lead-discovery-openclaw` 中）做独立交叉源验证。Layer 1 的三道 upstream gate 只能校验交付形式合规性（硬数字有溯源 / 不含 typo / estimate 标注规范），但**数据语义正确性**（pre vs post restatement / ROE 口径 / 股价基准）需要独立二源拉取数据来打分 —— 这是 `data-quality-audit` 的职责。validate-delivery 在 overall PASS 时会自动在 stdout 尾部打印 "Next step: run data-quality-audit skill …" 提示。

海天味业 2026-04-19 的 audit 就是一例：三道 upstream gate 全绿，但 data-quality-audit 抓到 EPS 2022 pre/post-restatement FAIL（1.34 vs 1.11 差 20.7%）。现在 `--strict` 模式 + `restatement_aware` 规则已把这一类问题部分上移到 Layer 1，但完整的 pre/post 版本识别仍需 Layer 3 独立拉数对比。

## Output standard

- MD 底稿 + PPTX 交付
- `references/data-provenance.md` listing every number source
- `cn_typo_scan.py` output attached as QA evidence
- Absolute paths in final report

## Integration with existing skills

This skill **supersedes** the generic `customer-investigation` + `customer-analysis-pack` flow when target is a China entity. The banker analysis frame (`datapack-builder` 8-tab structure, `dcf-model` WACC methodology, `pitch-deck` slide conventions) still apply —— this skill adds the text-safety and CN-specific data-source layer on top of them.

For non-CN targets (US / EU / JP / KR / IN / SE-Asia / LATAM), use the generic skills without this overlay.

## Not in scope

- Non-Chinese company analysis (use generic banker skills)
- Experimental econometric validation with `aigroup-econ-mcp` (lab bundle only; not appropriate for banker client deliverables)
- Embedded markdown→pptx via `aigroup-mdtopptx-mcp` (lab bundle only)
