Browse reusable Agent Skills, each with a clear purpose and practical guidance.
Use when YouTube data is needed without Google API quotas or OAuth setup: transcripts, video metadata, channel info, search results, playlists. Triggers on pasted YouTube links, creator names, @handles, topic research, video summaries, channel browsing, or any request where YouTube content would help — even if not mentioned explicitly. Not for uploads, account management, or written-source-only research.
Use when structured YouTube data is needed: pasted video/channel/playlist links, transcripts for analysis, video metadata, channel upload history, search results, or playlist contents — without Google API quotas or OAuth. Triggers on YouTube URLs, creator names, topic research, or any request needing YouTube content, even if not mentioned explicitly. Not for uploads, account management, or written-source-only research.
Real-time source of truth for software and model versions. Activate when adding dependencies, installing packages, or identifying Gemini model names. Bypasses internal knowledge cutoffs by querying live registries (NPM, PyPI, Go Proxy) and official documentation.
TileLang Pass 功能分析与对比工具。触发条件：(1) 用户询问特定 pass 的功能、作用、原理、实现细节，关键词包括"XXpass是干什么的"、"介绍XXpass"、"XXpass的功能"、"XXpass怎么实现的"、"分析XXpass"；(2) 对比两个 pass 的差异、联系；(3) 查询某类 pass 列表；(4) 模糊匹配 pass 名称。支持精确匹配和模糊匹配，返回由浅入深的 Markdown 分析报告，包含伪代码、IR 变换示例、代码位置等。
Use when the user wants to find YouTube content on any topic: searching for videos or channels, finding creators who cover a subject, discovering tutorials, talks, or expert discussions, or looking up a channel by name or handle. Also use proactively when the user wants to research a topic and YouTube is a good source. Not for account management or written-source-only research.
Rigorously and honestly assess a NEW or proposed covariance / correlation / precision estimator, or a new covariance scoring rule, using precise. Use when someone proposes, asks to evaluate, or wants to compare a covariance methodology. Covers implementing it to the contract, conformance, benchmarking against the registry, out-of-sample validation, and statistically defensible inference.
Score and compare covariance estimates with precise's assessor panel. Use when you need to judge an estimate out-of-sample or rank competing estimators — and especially in high dimensions, where the plain held-out likelihood is misleading.
Provides real-world API endpoint examples and specifications from well-known platforms and domain-specific systems. Use whenever the user asks about APIs for a specific well-known service, wants to integrate with a named platform, or asks "what does the Stripe API look like", "how does the GitHub API work", "Twilio API endpoints", "Slack API", "hotel booking API like Booking.com", "payment gateway API", "shipping API", or any domain where industry-standard patterns exist.

Load when a story needs factual grounding the writer doesn't have: historical detail, cultural texture, domain accuracy, or how other authors handled similar material. Pass the question and story context; returns a sourced report the writer can draw from.
Crawl an entire website or section and extract content from every page. Use when you need content from many pages under a common URL prefix: "crawl the whole site", "get all docs pages", "scrape every blog post", "download the full docs for RAG", "extract all pages under /api". Async BFS — starts a job and polls for results. Step 4 of the crw workflow ladder.
