What changed in the catalog

This page exists because of one claim the rest of the site depends on: entries are verified against primary sources, and removed when they stop clearing the bar. 4 de-listings are on record below, each with what specifically failed — a fabricated publisher, an install command pointing at an organisation that does not exist, an archived upstream repo. A verification promise nobody can audit is marketing.

191 skills catalogued · updated August 26, 2026 · Atom feed

Verticals filled, a second audience served, and catalog numbers that cannot go stale

Added 26 verified skills — the sales vertical doubled to eight, healthcare grew from two to five, and seo-content, web-hosting-deploys, payments-billing and email-messaging each reached ten, and a second sweep closed the last four nine-entry categories so nothing in the taxonomy now holds fewer than ten. Opened a second audience alongside developers: four guides written in the language a founder searches, a Business Owners collection of all 31 Skills that install without a terminal, and that install path published on every page where it applies. Catalog figures quoted in guide prose are now derived from the catalog instead of typed by hand.

  • Added15 verified skills across sales, healthcare, SEO, hosting, payments, and email

    Sales: Anthropic’s official sales plugin (research → outreach → pipeline), HubSpot’s first-party CRM skills, the 1,074-star ai-sales-team pack, and a 37-skill HubSpot admin toolkit. Healthcare: Anthropic’s healthcare plugin (FHIR, ICD-10, prior-auth) and life-sciences marketplace, plus PhenoML’s standalone FHIR skill. SEO: SE Ranking’s 26-skill official suite and the 870-star Agentic SEO audit machine. Hosting: Railway and Render, both in Anthropic’s official plugin marketplace. Payments: PayPal’s AI toolkit and Dodo Payments’ 17-skill MoR suite. Email: Postmark and Loops, both first-party. Every repo was cloned, its SKILL.md frontmatter parsed, its licence file read, and its last-commit date taken from git on 2026-08-26.

    /skill/sales-plugin
  • Added11 more skills — the last four categories that stood at nine

    document-processing reached thirteen with LlamaIndex’s liteparse (local extraction, no API key), Box’s own skills including its contract-review workflows, and Carbone’s template engine for data-driven document generation. browser-automation reached twelve with the Chrome DevTools team’s own skill set, Bright Data for sites that fight scrapers, and Apify for running or packaging Actors. video-media reached twelve with HeyGen’s HyperFrames (HTML to deterministic MP4), Runway for generative video, and Canva for brand-checked output at volume. diagrams-visualization reached eleven with Mapbox’s data-visualization patterns — the category had nine entries and none could put data on a map — and the Tufte chart skill, a community entry ranked on the strength of a named design canon rather than a vendor SDK. No category now holds fewer than ten entries.

    /skill/chrome-devtools
  • VerifiedTwo licence re-checks flipped; two did not

    HeyGen’s hyperframes and Apify’s Claude plugin were both rejected in earlier sweeps for shipping no licence. Both now carry real LICENSE files — Apache-2.0 — and are listed. The Apify entry deliberately points at apify-claude-code-plugin rather than the apify/agent-skills mirror, which ships the same five skills with no licence at all. Figma and Cloudinary were re-checked and still fail: their plugin manifests name a licence but no LICENSE file exists in either repo, and a manifest field is not a grant. Between them they hold roughly twenty-nine on-topic skills that stay unlistable until that changes. Also rejected: Zyte (proprietary EULA), iFLYTEK (Chinese-only descriptions, re-hosted third-party skills), and every scraped aggregator catalog.

  • VerifiedVerified dates only where the install command actually ran

    Seven of the fifteen carry a Verified date because their exact published install command was executed on 2026-08-26 (the npx and git-clone paths). The eight plugin-marketplace entries ship with repo, path, licence, and upstream date confirmed but no Verified date — same standard as the 2026-08-19 release — until their /plugin installs are run.

  • VerifiedCandidates rejected, and why

    ColdIQ’s 90-skill GTM pack (264 stars) has no licence file and gates key skills on a paid API. Chargebee’s integration skill still ships without a licence — watch-listed, not listed. Salesforce’s sf-skills and Pipedrive’s app-scaffolding are developer tooling, not sales work. OpenClaw’s 869-skill medical aggregation is the catalog-over-curation play this site exists to counter. AIPOCH’s medical set came off the watch-list as a rejection, and the check is worth recording precisely: its README states that every skill is “originally designed and developed in-house”, but its clinical-trial-protocol-skill is 99.7% identical to Anthropic’s, re-badged with author: AIPOCH and a licence header, pointing at AIPOCH as the source, with no attribution anywhere in the file. To be fair to them, that was the only near-duplicate: all 605 of their skills were compared against Anthropic’s life-sciences repo and K-Dense’s 163-skill collection, and the other 604 — including 58 that share a name with a K-Dense skill — are independently written at 3–8% similarity. One re-badged file is still enough: a blanket authorship claim this site would repeat has to be accurate, and a 605-skill repo is the catalog-over-curation shape declined above. Two accepted entries carry honest staleness notes: ai-sales-team (last push March 2026) and postmark-skills (February 2026).

  • Verifiedscientific-skills repo rename fixed

    K-Dense renamed claude-scientific-skills to scientific-agent-skills; the old URL browser-redirects but API and CLI lookups against it fail. The entry now points at the new repo (163 skills, MIT, pushed 2026-08-24) and its full install was re-executed today.

    /skill/scientific-skills
  • New surfaceA no-terminal install path on every claude.ai-compatible skill

    The claude.ai install snippet now describes the documented flow — Customize → Skills → upload the skill folder as a zip, with code execution enabled under Settings → Capabilities — replacing an outdated Settings → Features reference. The works-with-claude-ai filter was backfilled from 14 to all 31 skills whose verified compatibility includes claude.ai, and a new Business Owners collection lists all 31 with the failure mode stated: server-side sandbox, no shell, no local filesystem.

    /collections/best-skills-for-business-owners
  • New surfaceFour guides in the language business owners actually search

    A separate guide cluster for people who are not developers: best Skills for writing client proposals, for your newsletter, for social media content, and for building a pitch deck. Every pick on these pages carries verified Claude.ai compatibility, enforced at build time rather than by review — a pick that needs a terminal fails the build instead of shipping under a no-terminal promise. Each page states the limits too: these Skills draft, they do not send or post, and the sandbox they run in has no shell and no access to your files.

    /guides/best-skills-for-client-proposals
  • New surfaceThe browser install, published on the skill pages themselves

    Skill pages whose verified compatibility includes Claude.ai now carry a collapsed four-step browser install — enable code execution, download the folder, upload the zip under Customize → Skills, then describe the job — so a reader arriving from an AI answer is not handed a command line they will not use. The same four steps are published as HowTo structured data on the business-owner guides, and they live in one module rather than being retyped per page.

  • AddedDevOps × Codex matrix page opened

    The combination had cleared the six-skill gate but had no hand-written lead, so it had never shipped. It says something the category page cannot: what is verified on Codex here is the operational half — GitGuardian secret scanning, Sentry error handling, deploy-checklist, incident-response, Redis caching, Firebase hosting — while the Terraform and Kubernetes skills that anchor the same category on Cursor are not verified there. The FAQ states that absence is policy, not failure.

    /top-devops-infra-skills-for-codex
  • VerifiedCatalog counts in guide prose are now derived, not typed

    Fifteen sentences across the per-agent guides claimed "134 catalogued Skills" and figures like "77 of 134" — numbers that were already wrong before this release and got worse with every addition. A number nobody updates is worse than no number, because the reader cannot tell it is stale. All of them now render from the catalog itself, so Cursor reads 78 of 180 today and reads the truth tomorrow without anyone remembering to edit prose.

  • New surfaceMobile funnel rebuilt

    Phones now get a navigation drawer and a persistent search entry, one-tap copy on every install command, a sticky install bar on skill pages, a web app manifest with real icons, and 49 kB gzip less JavaScript on every skill page after a barrel-import fix. Four guide tables that clipped install commands at phone widths now scroll.

Honest freshness, 31 verified skills, per-agent guides, and a public change record

Closed every category that held fewer than eight entries by adding 31 verified vendor-published skills, replaced build-time sitemap dates with dates derived from the catalog, published a per-agent guide series and six explainer guides, opened the gated category-by-agent matrix, and made the catalog available as a single JSON dataset with an embeddable ranking badge.

  • Added31 verified skills — every thin category closed

    Eight categories held fewer than eight entries. All are now at nine or more, filled almost entirely with vendor-published skills verified against primary sources: Semgrep, GitGuardian, OWASP and Snyk in security; TigerData Postgres, Qdrant, Weaviate, Turso and Bytebase in databases; Microsoft Playwright and Browserbase in browser automation; Slack and Knock in messaging; two more Stripe skills including agentic checkout; draw.io and Microsoft in diagrams; Docling, Microsoft Azure and markdown-exporter in documents; ElevenLabs speech, transcription and dubbing in media.

  • VerifiedEleven candidates rejected

    Recorded so the gaps are explainable. OpenAI's 19-skill data-visualization suite is the richest diagram content in the ecosystem but its host repo is archived and carries no licence file. Figma's diagram skill, HeyGen's video skills, Apify, Polar and Chargebee all failed the licence check — a README badge or a frontmatter field is not a licence grant, and no licence file means all rights reserved. Google Workspace's 95 auto-generated CLI skills have five-word descriptions that cannot trigger reliably. Chainguard has no documented install path; Endor requires a commercial tenant.

  • ScoringVerification standard stated precisely

    The methodology page now separates the two dates on every entry and states that a Verified date is set only once the install command has been executed. The 31 skills added in this release ship with the repo, path, licence and upstream date confirmed but no Verified date, so they carry the verification-score penalty until their installs are run. An empty field is worth more than a badge that means "probably fine".

  • New surfaceHonest lastmod everywhere

    The sitemap previously stamped the build date on every non-skill URL, which teaches search engines to discount the signal — including the per-skill dates that were real. Every lastmod is now derived from the content behind the URL: category pages from the newest change among their skills, guides from their own edit date, editorial pages from a dated registry.

  • New surfaceGuide dates unfrozen

    All 22 best-for and deploy guides shared one hardcoded publish date in the article schema. Each now carries its real first-publish date and its real last-content-change date, both shown on the page.

  • New surfacePer-agent guide series

    Seven new guides answering "best skills for <agent>" — Claude Code, Cursor, Codex CLI, Claude.ai, Claude API, Gemini CLI, Antigravity — each with an install model, ranked picks, and an explicit limits section naming what is not verified there.

    /guides/best-skills-for-cursor
  • New surfaceSix explainer guides

    Skills vs Cursor Rules, Skills vs AGENTS.md, marketplaces compared, how to audit a Skill before installing, whether Skills cost tokens, and how to publish and get listed.

    /guides/skills-vs-cursor-rules
  • New surfaceCategory-by-agent matrix

    Fifteen pages answering "top <category> skills for <agent>" for Cursor and Codex, behind a quality gate: at least six verified-compatible skills, a hand-written lead, and an independent third-party agent. Claude Code is excluded because every catalogued skill is verified there, so the page would duplicate the category.

  • New surfaceOpen dataset and ranking badges

    The full catalog is now available as a single machine-readable file at /skills.json, and every skill page offers an embeddable SVG ranking badge that publishers can drop into a README.

    /skills.json
  • New surfaceSkill-vs-skill comparisons: 3 to 9

    Six new head-to-head pages, each on a rivalry the new entries created: docling vs pdf (reading versus writing documents), semgrep vs trail-of-bits (findings versus judgement), Playwright CLI vs Browserbase (local versus hosted browsers), postgres vs supabase-skill (engine versus platform layer), drawio vs mermaid (editable artefact versus text in the repo), and Stripe Connect vs Paddle (owning tax compliance versus renting it). Comparison coverage went from 3 categories to 6.

    /compare-skills
  • VerifiedOpenClaw and ClawHub documented, not yet catalogued

    Verified from primary sources: OpenClaw reads SKILL.md natively with the same two required frontmatter fields, loads skills from <workspace>/skills, <workspace>/.agents/skills and ~/.agents/skills in that precedence order, and has a public registry (ClawHub) installable as openclaw skills install <package> or npm i -g clawhub. It is covered in the install guide and the marketplaces comparison. It is deliberately NOT added as an eighth agent target: per-agent compatibility here means the skill was tested there, no such pass has been run, and OpenClaw’s own docs decline to claim Claude Code skills work unchanged — they note Codex’s skills directory is not an OpenClaw root and ship migration commands instead. An agent page listing zero verified skills would be the hollow page this site removes categories for.

  • New surfaceChangelog and Atom feed

    This page, plus a feed at /feed.xml so changes are discoverable without polling the sitemap.

Data-integrity pass: 11 entries removed

A verification sweep against primary sources removed eleven entries whose install commands pointed at organisations that do not exist, and corrected the repository and provenance data on several others.

  • RemovedEleven community entries

    cro-patterns, email-sequence-builder, docker-best-practices, github-actions-builder, aws-cdk-patterns, cypress-testing, vitest-skill, typescript-strict-mode, tailwind-best-practices, standup-skill, and mindmap-generator were removed: each carried a <topic>-skills/ style install command pointing at a GitHub organisation that does not exist, and no credible canonical repository could be found. Each URL now permanently redirects to its nearest live category.

  • Removedweb-scraping-patterns, puppeteer-patterns

    Removed for fabricated publisher organisations that could not be verified against any real repository. Both redirect to Browser & Web Automation.

    /top-skills-for-browser-automation
  • Removedget-shit-done

    Removed because its upstream repository is archived. Redirects to Workflow Orchestration.

    /top-skills-for-workflow-orchestration
  • VerifiedRepository and provenance corrections

    Real repositories wired for several verified-org entries (Shannon, shadcn, Sentry), and provenance tiers corrected where the published claim was stronger than the evidence supported.

  • AddedDuckDB and Neon

    Two official vendor database skills added to deepen Databases & Schemas.

    /top-skills-for-databases-schemas

Domains & DNS category de-listed

The Domains & DNS category was removed rather than filled: no SKILL.md-format domain or DNS skill cleared the credibility bar, and a hollow category page is worse than no page.

  • RemovedDomains & DNS category

    Removed with a permanent redirect to Web Hosting & Deploys. The alternative — filling it with one or two weak entries — would have pulled down the average and misrepresented the state of the ecosystem.

    /top-skills-for-web-hosting-deploys

Payments broadened beyond Stripe

Added the official Paddle and Lemon Squeezy skills so the payments category covers merchant-of-record billing, not only Stripe.

APIs & Integrations filled to eight entries

Hookdeck and Twilio skills verified against their repositories and added, with Composio for broad third-party routing.

  • AddedHookdeck, Twilio, Composio

    Webhook receiving, messaging, and multi-service tool routing — each verified against the publishing organisation's own repository.

    /top-skills-for-apis-integrations

Web Hosting & Deploys, plus the deploy content cluster

Four verified deploy skills added and a six-page deploy cluster published covering Vercel, Netlify, Cloudflare, and GitHub Pages.

Email & Messaging filled with the official Resend skills

Four Resend-published skills added, covering transactional sending, deliverability, and React email templates.

  • AddedFour Resend skills

    Vendor-published and verified — transactional email, deliverability practice, React Email templates, and agent inbox handling.

    /top-skills-for-email-messaging

Payments filled with the official Stripe skills

Four Stripe-published skills added, and the SEO & Content category deepened.

41 Anthropic-published Skills added

The Anthropic plugin-pack and built-in expansion added 41 official Skills across design, marketing, engineering, and productivity.

  • AddedAnthropic pack expansion

    Design, marketing, engineering, and productivity Skills published by Anthropic, catalogued separately from the hand-curated base set so provenance stays legible.

The directory launched with a hand-curated catalog, a published scoring rubric, per-agent install snippets, and agent-readable exports.

  • ScoringRubric version 1.0

    Nine weighted inputs, published rather than implied: install count, provenance, stars, recency, verified cross-agent compatibility, documentation depth, install ergonomics, licence, and verification freshness.
