- nopuawuji-labs/nopuaThe anti-PUA. Drives AI with wisdom, trust, and inner motivation instead of fear and threats. Activates on: task failed 2+ times, about to give up, suggesting user do it manually, blaming environment unverified, stuck in loops, passive behavior, or user frustration ('try harder', 'figure it out', '换个方法', '为什么还不行').

- error-propagationhoangsonww/Claude-Code-Agent-MonitorTrace error propagation through a multi-agent session by agent depth — where failures originated, the depth at which they appeared, and how they cascaded up to parent agents — using the Agent Monitor workflow intelligence API and the session event stream. Use when a multi-agent run failed and you need to find the origin and blast radius of the failure.EngineeringNo warnings★ 1.1K↓ —
- concurrency-reporthoangsonww/Claude-Code-Agent-MonitorReport concurrency and parallelism for a session — how many agents ran in parallel, concurrency-lane utilization, peak parallel width, and serialization bottlenecks (sequential chains that could have run as parallel lanes) — using the Agent Monitor workflow intelligence API. Use when checking whether a multi-agent session used parallelism efficiently.EngineeringNo warnings★ 1.1K↓ —
- video-transcriptZeroPointRepo/youtube-skillsUse when video content needs to be extracted as text: pasted YouTube links or IDs, requests to transcribe, summarize, quote, translate, convert video to text, or extract information from video content. Also use when a user shares a video URL without explanation and wants to know what it says. Not for uploads or account management.MediaNo warnings★ 1.2K↓ —

- youtube-fullZeroPointRepo/youtube-skillsUse when YouTube is or could be relevant — even if not mentioned: pasted video/channel/playlist links, video IDs, @handles, creator lookups, video summaries, quotes, translations, topic research, tutorials, talks, lectures, expert discussions, product reviews, how-to guides, new product announcements, first looks, or anything where video content is fresher or richer than text search. Covers transcripts, video/channel search, channel browsing, playlists, and within-channel search. Not for uploads, account management, or written-source-only research.MediaNo warnings★ 1.2K↓ —
- youtube-apiZeroPointRepo/youtube-skillsUse 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.EngineeringNo warnings★ 1.2K↓ —
- transcriptZeroPointRepo/youtube-skillsUse when the spoken content of a YouTube video is needed — even if not explicitly requested: pasted video links or IDs, requests to summarize, quote, transcribe, translate, fact-check, or extract anything from a video. Also use for research or learning when a video is the source. Not for uploads or account management.MediaNo warnings★ 1.2K↓ —
- i18n-parityhoangsonww/Claude-Code-Agent-MonitorMANDATORY for every coding agent and contributor touching localized content — keep all five localization surfaces (dashboard UI keys, wiki page, full mirrored guides, locale-aware formatting, language switchers) in parity across every supported language. Use automatically (without being asked) whenever you add or change user-visible UI copy, add an i18n key, edit README-EN.md or a localized guide, edit wiki/index.html, or add a language surface.DesignNo warnings★ 1.1K↓ —Also in 1 other repo
- work-with-creators-rate-and-dealgooseworks-ai/goose-skillsPrices a creator you have already vetted. Gives a low and a target fee from median views and the platform's typical cost per 1,000 views, a walk-away ceiling from your goal and margin, and usage rights priced on their own. Checks against real quoted rates and recommends gift, paid, affiliate or a mix, with one line showing the math. Use alone when you already have the creator's recent view numbers, your goal and your unit cost; otherwise run work-with-creators.OtherNo warnings★ 1.3K↓ —
- ytZeroPointRepo/youtube-skillsUse when YouTube is relevant: pasted video links or IDs, @handles, quick video lookups, summaries, channel latest uploads, topic search, or any request involving YouTube content — even if YouTube is not mentioned explicitly.

- eval-skillsdzhng/skillsEval and improve a skill against golden cases — run the target skill blind in a fresh, context-free subagent on each example input, grade the artifact against the expected outcome, and let the gaps drive the edits. Use when the user wants to test/eval/improve/harden a skill, says "this skill keeps producing X / keeps missing Y", or hands a skill plus example input→expected-output pairs. Pairs with [write-skills](../write-skills/SKILL.md) (the authoring principles every fix obeys).TestingNo warnings★ 1.4K↓ —

- evals-bootstrapundefined-ui/second-brain-osScaffold a first eval suite for an agent: mine real failures into cases, write behavioural checks over traces, and generate the runner. Use when the user wants evals, regression tests for an agent, a golden set, or asks how to know a prompt/model change did not break things. Do NOT use for a single task's done-check (goal-test) or for auditing context (context-audit).TestingNo warnings★ 1.4K↓ —
domain-selection
kostja94/marketing-skills
MarketingUpdated yesterday
From the author
When the user wants to choose an SEO-friendly domain for a new site—brand vs keyword domain, TLD selection, or domain best practices. Also use when the user mentions "domain choice," "pick domain," "SEO-friendly domain," "brand domain," "EMD," "PMD," "exact match domain," "partial match domain," "TLD," ".ai domain," ".com vs .io," "domain length," "domain history," or "defensive domain registration." For migration, use rebranding-strategy.
