Claude Skills
The open format is called Agent Skills and works in Claude Code, Codex, Cursor and other agents — most people know it as Claude Skills.
Every Agent Skill we could find on GitHub, deduplicated by content. 86 543 files from 2 102 authors, of which 68 261 are unique — the rest is the same skill repackaged into someone else's repository. For each one: what it weighs in tokens, whether it ships runnable scripts, and which MCP servers it needs.
Convert HTML and Markdown content into Portable Text blocks for Sanity. Use when migrating content from legacy CMSs, importing HTML or Markdown into Sanity, building content pipelines that ingest external content, converting rich text between formats, or programmatically creating Portable Text documents. Covers @portabletext/markdown (markdownToPortableText), @portabletext/block-tools (htmlToBlocks), custom deserializers, and the Portable Text specification for manual block construction.
Vercel Connect expert guidance — securely obtain scoped OAuth tokens for third-party services (Slack, GitHub, MCP servers, OAuth, Snowflake) on behalf of apps or users via Vercel OIDC. Use when wiring up third-party API access, connecting to MCP servers, sending Slack messages, or accessing GitHub APIs.

Semantic Scholar CLI (`s2`) for on-demand citation graph lookup: papers a work cites, papers that cite a work, and graph search across 200M+ papers. Use whenever the user asks for Semantic Scholar, S2, cited papers, references, bibliography, citing papers, citation count from Semantic Scholar, or papers outside a local catalog. Prefer `s2` over curl or ad-hoc Graph API requests.
Fixes broken typing checks detected by ty, make typing, or make check-repo. Use when typing errors appear in local runs, CI, or PR logs.
> Write idiomatic application code with the ClickHouse Node.js client (`@clickhouse/client`). Use this skill whenever a user is *building* against the Node.js client — configuring the client, pinging, inserting rows in JSON or raw formats, selecting and parsing results, binding query parameters, managing sessions and temporary tables, working with data types or customizing JSON parsing. Do NOT use for browser/Web client code.
> Troubleshoot and resolve common issues with the ClickHouse Node.js client (@clickhouse/client). Use this skill whenever a user reports errors, unexpected behavior, or configuration questions involving the Node.js client specifically — including socket hang-up errors, Keep-Alive problems, stream handling issues, data type mismatches, read-only user restrictions, proxy/TLS setup problems, or long-running query timeouts. Trigger even when the user hasn't precisely named the issue; vague symptoms like "my inserts keep failing" or "connection drops randomly" in a Node.js context are strong signals to use this skill. Do NOT use for browser/Web client issues.
MUST USE when reviewing ClickHouse schemas, queries, or configurations. Contains 31 rules that MUST be checked before providing recommendations. Always read relevant rule files and cite specific rules in responses.
Use when migrating ClickHouse docs pages from Docusaurus (clickhouse-docs) to Mintlify format in this repo, or when wiring up the migration script. Covers frontmatter rewrites, body transforms, component mapping, link normalization, and redirect generation. Slugs are canonical and must never be rewritten.
Use when a user wants to deploy ClickHouse to the cloud, go to production, use ClickHouse Cloud, host a managed ClickHouse service, or migrate from a local ClickHouse setup to ClickHouse Cloud.
Use when a user wants to build an application with ClickHouse, set up a local ClickHouse development environment, install ClickHouse, create a local server, create tables, or start developing with ClickHouse. Covers the full flow from zero to a working local ClickHouse setup.

Ask which skill or flow fits your situation. A router over the skills in this repo.
Configure this repo for the engineering skills — set up its issue tracker, triage label vocabulary, and domain doc layout. Run once before first use of the other engineering skills.
Break a plan, spec, or PRD into independently-grabbable issues on the project issue tracker using tracer-bullet vertical slices.
Plan a huge chunk of work — more than one agent session can hold — as a shared map of decision tickets on your issue tracker, and resolve them one at a time until the way to the destination is clear.

> Use this skill when the user wants a polished, shareable, source-grounded, self-contained HTML artifact in the Birch visual system for engineering, product, planning, review, status, incident, process, codebase, data, or benchmark communication. Trigger for one-pagers, visual summaries, reports, dashboards, module/process explainers, implementation plans, design-direction comparisons, PR/change writeups, findings-first code reviews, incident/status reports, briefing decks, flow diagrams, numeric/data briefs, model/run/token/ time/cost reports, and design-system references. Do not use it for editing production web apps, React/Vue components, or ordinary chat answers.
Create a polished social demo video (MP4, 4:3, ~10s) for any Hugging Face Space with the space-demo-kit renderer. Use whenever the user asks for a demo, promo, showcase, or social video of a HF Space or model. Covers template selection (i2v, t2v, edit, avatar, a2a, gallery, vqa), manifest schema, live asset capture, rendering, verification, and delivery.

Get an Expo app running on the user's phone from a Tuft machine. Read this at the start of any session where the user asks for an app — including brand-new apps, before scaffolding or picking how to deliver it; assume the deliverable is an installable build on their device, not a web preview, unless they say otherwise, and start that build before feature work so it lands mid-session. Also use for EAS account/Apple/device setup via the Tuft dashboard flow, making development builds with EAS, Expo dev-client iteration, remotely exposing Metro with `tuft host`, generating a dev-client deep link, diagnosing device-only failures with Tuft telemetry, deciding whether a native rebuild is required, and handing a working preview back to the user.
Install a specific Xcode version on a Mac using the xcodes CLI, handing the Apple ID sign-in (password + 2FA) to the user through a shared live terminal. Use when a task needs Xcode/simulators and the machine doesn't have the right version, or the user asks to install/upgrade Xcode.

Compare a validated Next.js reproduction on its reported version and the latest published next@canary under equivalent conditions. Use when determining whether a confirmed vercel/next.js issue still reproduces on canary or appears fixed there.
Turn a validated Next.js reproduction and canary verification into the smallest appropriate regression test in vercel/next.js. Use when a confirmed issue needs a focused test that proves the reported behavior and fits the existing Next.js test suite.
Implement and validate the smallest correct fix for a confirmed issue in vercel/next.js after reproduction, canary verification, and regression-test work. Use when a focused failing Next.js regression test exists and the product code must be corrected without weakening that test.
Locate the introduction or fix boundary for a validated Next.js regression using releases or commits and an executable reproduction. Use after reported-version-versus-canary verification when a vercel/next.js maintainer needs the last unchanged and first changed version or commit.
Reproduce and validate a reported Next.js issue using real code and runtime evidence. Use when investigating whether a vercel/next.js bug report is reproducible, repairing an incomplete reproduction, or creating the smallest standalone reproduction when none is provided.
