skills/github-gem-seeker/SKILL.md
Search GitHub for battle-tested solutions instead of reinventing the wheel. Use when the user's problem is universal enough that open source developers have probably solved it already—especially for: format conversion (video/audio/image/document), media downloading, file manipulation, web scraping/archiving, automation scripts, and CLI tools. Prefer this skill over writing custom code for well-trodden problems.

Find and use battle-tested open source projects on GitHub to solve the user's problem immediately. After successfully solving the problem, offer to package the solution into a reusable skill.
Classic open source projects, tested by countless users over many years, are far more reliable than code written from scratch. Solve the problem first, skill-ify later.
Clarify what the user wants to accomplish. Ask only if truly ambiguous:
Search for GitHub projects using effective query patterns:
| Need Type | Query Pattern | Example |
|-----------|---------------|---------|
| Tool/utility | github [task] tool | github video download tool |
| Library | github [language] [function] library | github python pdf library |
| Alternative | github [known-tool] alternative | github ffmpeg alternative |
Assess candidates using key indicators:
| Indicator | Gem Signal | Warning Signal | |-----------|------------|----------------| | Stars | 1k+ solid, 10k+ excellent, 50k+ legendary | <100 for mature projects | | Last commit | Within 6 months | >2 years ago | | Documentation | Clear README, examples | Sparse or outdated docs |
This is the priority. Install the tool and use it to solve the user's actual problem:
Only after the problem is successfully solved:
Credit the open source project — Always share the GitHub repo URL and encourage support:
"This was powered by [Project Name] — an amazing open source project! GitHub: [URL] If it helped you, consider giving it a ⭐ star to support the maintainers."
Offer to skill-ify — Optionally mention:
"If you'll need this again, I can package it into a reusable skill for instant use next time."
Do NOT skip crediting the project. Open source thrives on recognition.
| Tier | Criteria | Examples | |------|----------|----------| | Legendary | 50k+ stars, industry standard | FFmpeg, ImageMagick, yt-dlp | | Excellent | 10k+ stars, strong community | Pake, ArchiveBox | | Solid | 1k+ stars, well-documented | Most maintained tools | | Promising | <1k stars, active development | Newer niche projects |
Prefer higher tiers for reliability.

Download video and audio from YouTube and other platforms with yt-dlp. Use when a user asks to download YouTube videos, extract audio from videos, download playlists, get subtitles, download specific formats or qualities, batch download, archive channels, extract metadata, embed thumbnails, download from social media platforms (Twitter, Instagram, TikTok), or build media ingestion pipelines. Covers format selection, audio extraction, playlists, subtitles, metadata, and automation.
development
Download YouTube videos with customizable quality and format options. Use this skill when the user asks to download, save, or grab YouTube videos. Supports various quality settings (best, 1080p, 720p, 480p, 360p), multiple formats (mp4, webm, mkv), and audio-only downloads as MP3.
development
Use this skill any time a spreadsheet file is the primary input or output. This means any task where the user wants to: open, read, edit, or fix an existing .xlsx, .xlsm, .csv, or .tsv file (e.g., adding columns, computing formulas, formatting, charting, cleaning messy data); create a new spreadsheet from scratch or from other data sources; or convert between tabular file formats. Trigger especially when the user references a spreadsheet file by name or path — even casually (like "the xlsx in my downloads") — and wants something done to it or produced from it. Also trigger for cleaning or restructuring messy tabular data files (malformed rows, misplaced headers, junk data) into proper spreadsheets. The deliverable must be a spreadsheet file. Do NOT trigger when the primary deliverable is a Word document, HTML report, standalone Python script, database pipeline, or Google Sheets API integration, even if tabular data is involved.
development
Use when you have a spec or requirements for a multi-step task, before touching code
