从 X (Twitter) 链接下载图片或视频到 ~/Downloads。
依赖
yt-dlp(已安装)
执行流程
1. 解析输入
从用户输入中提取 X/Twitter URL。支持的格式:
https://x.com/user/status/123456https://twitter.com/user/status/123456https://mobile.twitter.com/user/status/123456- 带查询参数的 URL(yt-dlp 自动处理
?s=20等追踪参数)
缩短链接(t.co)先解析:curl -Ls -o /dev/null -w '%{url_effective}' "SHORT_URL"
如果用户没有提供 URL,用 AskUserQuestion 要求提供。
2. 尝试直接下载(视频优先)
直接用 yt-dlp 下载,无需先探测:
yt-dlp -o "~/Downloads/%(uploader)s_%(id)s.%(ext)s" "URL"
如果成功(视频推文),完成。跳到步骤 4 汇报结果。
3. 视频下载失败时,提取图片
yt-dlp 对纯图片推文可能报错。此时用 --dump-json 提取图片 URL:
yt-dlp --dump-json "URL" 2>&1
判断结果:
- JSON 中有
thumbnails数组 → 提取图片 URL - JSON 为空或报错
no video→ 推文无媒体,告知用户"该推文不包含可下载的图片或视频" - 报错含
login/authentication→ 需要登录(见故障排除) - 其他错误 → 报告具体错误信息
图片下载:
从 JSON 的 thumbnails 数组提取所有图片 URL,替换 name=small 或 name=medium 为 name=orig 获取原图,然后逐一下载:
curl -L -o ~/Downloads/tweet_ID_1.jpg "https://pbs.twimg.com/media/xxx?format=jpg&name=orig"
curl -L -o ~/Downloads/tweet_ID_2.jpg "https://pbs.twimg.com/media/yyy?format=jpg&name=orig"
文件扩展名跟随 URL 中的 format 参数(jpg/png/webp)。
4. 汇报结果
下载完成后,用 ls -lh 列出已下载的文件:文件名、大小、路径。
故障排除
需要登录
yt-dlp 报错含 login / Sign in / age-restricted 时,加 --cookies-from-browser chrome:
yt-dlp --cookies-from-browser chrome -o "~/Downloads/%(uploader)s_%(id)s.%(ext)s" "URL"
推文无媒体
纯文字推文没有可下载的媒体。告知用户即可。

Implementation Guide▌
Prerequisites
- ›Claude Desktop or compatible AI client
- ›Access to product documentation and roadmap tools (Jira, Notion, etc.)
- ›Understanding of product management frameworks (RICE, Jobs-to-be-Done, etc.)
- ›Stakeholder contact information and communication channels
Time Estimate
30-60 minutes to see productivity improvements
Installation Steps
- 1.Install product management skill
- 2.Start with user story generation for known feature
- 3.Progress to competitive analysis: research 2-3 competitors
- 4.Use for roadmap prioritization: apply RICE/ICE scoring
- 5.Draft stakeholder communications and refine based on feedback
- 6.Build template library for recurring PM tasks
- 7.Share effective prompts with product team
Common Pitfalls
- ⚠Not validating competitive research—verify facts before sharing
- ⚠Accepting user stories without involving engineering team
- ⚠Over-relying on frameworks without qualitative judgment
- ⚠Not customizing outputs to company culture and communication style
- ⚠Skipping stakeholder validation of generated requirements
Best Practices▌
✓ Do
- +Validate research and competitive analysis with real data
- +Collaborate with engineering when generating technical requirements
- +Customize frameworks and templates to your company context
- +Use skill for first drafts, refine with stakeholder input
- +Document successful prompt patterns for PM tasks
- +Combine AI efficiency with human judgment and intuition
✗ Don't
- −Don't publish competitive analysis without fact-checking
- −Don't finalize user stories without engineering review
- −Don't make prioritization decisions solely on AI scoring
- −Don't skip customer validation of generated requirements
- −Don't ignore company-specific context and culture
💡 Pro Tips
- ★Provide context: company goals, constraints, customer feedback
- ★Ask for alternatives: 'Show 3 ways to prioritize this roadmap'
- ★Request stakeholder-specific formatting: 'Executive summary vs. engineering spec'
- ★Use skill for 70% generation + 30% customization to company needs
When to Use This▌
✓ Use When
Use for user story writing, competitive research, roadmap prioritization, stakeholder communication, and PRD drafting. Best for reducing repetitive documentation and research work.
✗ Avoid When
Avoid for strategic product vision (requires deep customer empathy), pricing decisions (needs market and financial expertise), or when face-to-face customer discovery is more valuable than speed.
