Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00061 | $0.01465 |
| Opus 5 | $0.00030 | $0.00732 |
| Sonnet 5 | $0.00012 | $0.00293 |
| Haiku 4.5 | $0.00006 | $0.00146 |
Grade A, and why
chinese-video-transcribe-pdf scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 141 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Chinese Video Transcription to PDF
将中文视频转写为结构化文本并生成专业中文PDF报告。
核心工作流
1. yt-dlp 下载视频
2. ffmpeg 抽出音频(16kHz PCM) ← 关键步骤,避免视频解码问题
3. faster-whisper tiny/medium 模型转写(支持中文,无需字幕)
4. 整理 Markdown 报告内容
5. render_cn_report_pdf.py 生成 PDF
Step 1:下载视频
yt-dlp -f "bestvideo[ext=mp4]+bestaudio[ext=m4a]/best[ext=mp4]/best" \
-o "~/Downloads/%(title)s.%(ext)s" "VIDEO_URL"
如下载中断,用 --force-overwrites 或直接重新运行(yt-dlp 自动续传)。
Step 2:抽出音频(关键)
视频编码(AV1等)可能导致 Whisper 卡在43% 解码位置。必须先抽出音频:
ffmpeg -i "INPUT.mp4" -vn -acodec pcm_s16le -ar 16000 -ac 1 /tmp/audio.wav -y
参数说明:
-vn不要视频-acodec pcm_s16le线性PCM,避免压缩编码问题-ar 16000Whisper 推荐的采样率-ac 1单声道
Step 3:转写(faster-whisper)
不要用 openai-whisper CLI(输出 pipe 到 tail 时无法观察进度,且某些视频编码会卡住)。
用 Python API + faster-whisper:
from faster_whisper import WhisperModel
model = WhisperModel("tiny", device="cpu", compute_type="int8")
segments, info = model.transcribe(
"/tmp/audio.wav",
language="zh",
vad_filter=True,
vad_parameters=dict(min_silence_duration_ms=800)
)
results = []
for seg in segments:
results.append({
"start": round(seg.start, 2),
"end": round(seg.end, 2),
"text": seg.text.strip()
})
# 保存为 JSON
import json
with open("/tmp/transcript.json", "w", encoding="utf-8") as f:
json.dump({"segments": results, "language": info.language}, f, ensure_ascii=False, indent=2)
模型选择:
tiny— 最快(3分钟左右转写40分钟),中文识别准确率已很好medium— 更准但更慢,适合关键内容
Step 4:生成 Markdown 报告
根据转写内容整理 Markdown 结构,使用中文标题和自然段落。
Step 5:生成 PDF
重要决策点: ReportLab 渲染器的输出质量偏基础(markdown 直转,无 CSS 精排,层次感弱)。当用户需要专业/咨询风格报告时(如对方明确说"排版太差""咨询风格"),跳过 ReportLab,使用 HTML+CSS+Chrome 导出。
路径 A:基础版 — ReportLab(快速,排版一般)
python3 $SKILL_DIR/../../../openclaw-imports/chinese-pdf-report/scripts/render_cn_report_pdf.py \
--input /tmp/report.md \
--output ~/Downloads/输出报告.pdf
字体自动注册:SongtiSC(正文)、HeitiSC(标题)、KaitiSC(引用)。
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
- 12d ago First seen · 141 lines · 61 tokens per session scan A 71fa6913cd45
chinese-video-transcribe-pdf is a skill published in the GitHub repository davidtoby/agent-skills (10 stars, last pushed 1mo ago), licensed MIT. It adds 61 tokens to every session and 1,465 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
