- [A/B Test Auditor & Planner](https://skills-for-ai.com/skills/ab-test-auditor/) — Data · v2.6.0: A/B Test Auditor & Planner is an AI skill for experimentation — an A/B test significance calculator and audit that checks statistical significance, sample size and sample ratio mismatch (frequentist or Bayesian) and gives a clear ship / hold / iterate verdict.

B2B/B2C preset included.
- [Review Architect](https://skills-for-ai.com/skills/review-architect/) — Productivity · v2.3.0: Review Architect is an AI review skill for honest code review, design review and constructive feedback on almost anything — one shared review engine, plus a focused lens per subject built on the proven method: Nielsen heuristics + WCAG (design), Google code-review standard + OWASP (code), pre-mortem (decisions), blameless postmortem + 5 Whys (processes), SBI (feedback). Findings ranked by severity with concrete fixes, no sugar-coating.
- [No-Yes-Man](https://skills-for-ai.com/skills/no-yes-man/) — Productivity · v1.2.0: Tired of ChatGPT agreeing with everything? This system prompt stops the sycophancy and turns the people-pleasing assistant into an honest advisor: hard truth first, assumptions challenged, no empty flattery, every recommendation names its risk. Calibrated both ways — it agrees when you're right, owns its mistakes, and leaves the call to you.
- [Inbox Pro](https://skills-for-ai.com/skills/inbox-pro/) — Productivity · v1.5.0: Inbox Pro is an AI skill for Inbox Zero and GTD email management: it sorts your inbox into clear categories, decides one action per email (do <2 min, delegate, reply, schedule, archive), extracts tasks, dates and waiting-for, and drafts each reply for you. Spots phishing and only drafts — nothing is sent or deleted without you.
- [Code Reviewer Pro](https://skills-for-ai.com/skills/code-reviewer-pro/) — Development · v1.4.0: Code Reviewer Pro is an AI code-review skill for pull requests, diffs and files — reviewing line by line like a senior reviewer. Catches bugs, security flaws (OWASP/STRIDE) and missing tests with concrete fixes, paste-ready Conventional Comments and a clear verdict: LGTM / Request Changes.
- [CSV Whisperer](https://skills-for-ai.com/skills/csv-whisperer/) — Data · v1.6.0: CSV Whisperer is an AI data skill for tabular data that opens and fixes any broken or messy CSV: it auto-detects delimiter, encoding and column types, repairs garbled characters, profiles the data, compares and merges files, spots anomalies, and builds the right chart. Two-stage: quick triage first, then a clean read.
- [Weekly Planner](https://skills-for-ai.com/skills/weekly-planner/) — Productivity · v1.5.0: Weekly Planner is an AI planning skill that turns a messy to-do list into a realistic, time-blocked weekly schedule across one or more weeks: priorities (Eisenhower/MITs), deep work in your peak hours, breaks and ~20% buffer. Factors in your recurring workload, calibrates through reviews, and honestly says what won't fit instead of overloading you.
- [Newsletter Forge](https://skills-for-ai.com/skills/newsletter-forge/) — Marketing · v1.3.0: Newsletter Forge is an AI newsletter-writing skill that turns a single topic into a send-ready issue: A/B subject lines, a matching preview text, a scannable structure, the full draft in your brand voice, and a clear, benefit-driven CTA — plus a best-practice self-check for mobile, deliverability and GDPR. Real reader value, no clichés.
- [Web Vitals](https://skills-for-ai.com/skills/web-vitals-audit/) — Development · v1.9.1: Web Vitals is an AI web-performance audit skill that audits a website like the established pro tools — across seven categories each scored 0–100: performance (Core Web Vitals LCP/INP/CLS + lab metrics), accessibility (WCAG 2.2), best practices, SEO, security (TLS + security headers in the style of Mozilla Observatory/SSL Labs), mobile/responsive and privacy/GDPR. Delivers severity-ranked findings with concrete fixes per category, an overall overview and a leverage-sorted action list — and honestly distinguishes measured from estimated values.
- [Web AI Vitals](https://skills-for-ai.com/skills/ai-visibility-audit/) — Development · v1.7.0: Web AI Vitals is an AI-visibility (GEO) audit skill that checks how well a website can be crawled, read, understood and cited by AI answer engines (ChatGPT, Claude, Perplexity, Google AI Overviews/Gemini) — an AI-visibility/GEO audit across seven categories scored 0–100. The real levers first: can the AI bot even get in (robots.txt, CDN/Cloudflare blocks)? Is the content in the raw HTML (AI bots mostly DON’T render JavaScript)? Are there structured data (Schema.org/JSON-LD) and citable direct answers (GEO)? Plus trust & freshness (E-E-A-T, Bing index). AI guide files like llms.txt/ai.txt come last — honestly framed as a low-leverage bonus. Gives a concrete fix per finding with a recommendation strength and a leverage-prioritized action list.
- [Frontend Design](https://skills-for-ai.com/skills/frontend-design/) — Development · v1.3.0: Frontend Design is an AI skill for front-end UI design that doesn't look AI-generated: it builds distinctive, production-ready interfaces, checked for accessibility (WCAG), contrast, focus, layout shift and performance.
- [Brainstorm](https://skills-for-ai.com/skills/brainstorm/) — Creative · v1.1.0: Brainstorm is an AI brainstorming skill that runs a structured brainstorming session on any topic — generating ideas for products, projects, to-dos, campaigns, names, problems and decisions. Guides you question by question, produces many ideas with proven brainstorming techniques, and converges critically to a reasoned shortlist.
- [Analytics](https://skills-for-ai.com/skills/analytics/) — Data · v1.1.0: Analytics is an AI analytics skill that analyzes your Google Analytics 4 data and turns web, product and marketing numbers into clear actions. Three modes: advise tracking setup, analyze pasted GA4 exports/CSV/screenshots anywhere, or pull live GA4 data in code tools. Read-only, no PII.
- [Pen & Paper Companion](https://skills-for-ai.com/skills/pnp-companion/) — Creative · v1.1.0: Pen & Paper Companion is a tabletop-RPG companion skill that keeps ONE character across every session and campaign — story, allies, enemies, spells and gear live in files you own. Say "Open Vaelis" and your AI knows it all and plays them in-character. D&D, Pathfinder, Call of Cthulhu and more, one-shot to years-long campaign.
- [Discord Bot Architect](https://skills-for-ai.com/skills/discord-bot-architect/) — Development · v1.1.0: Discord Bot Architect is a Discord-bot building skill — your AI companion for building your own Discord bots, from your first bot to a large community system. Instead of loose snippets you get real architecture decisions (bot or webhook?), clean slash commands, buttons, modern modals and Components V2, plus permissions, rate-limit and timeout protection, GDPR and integrations (YouTube/Twitch/RSS). It understands Discord as a complete product, UI and API system — from setup to deployment.
- [AI Blueprint Assistant](https://skills-for-ai.com/skills/ai-blueprint-assistant/) — Productivity · v1.1.0: AI Blueprint Assistant is an AI project-planning skill that turns a rough idea into a complete, AI-ready blueprint before you build — project type, flagged assumptions, scope & non-goals, structure, roadmap, risks, Blueprint Score and a copy-paste handoff (AGENTS.md / CLAUDE.md) for ChatGPT, Claude, Cursor, Codex, Copilot or Gemini. Not software-only.
- [Deep Research](https://skills-for-ai.com/skills/deep-research-pro/) — Productivity · v1.1.0: Deep Research is an AI research skill for deep, multi-source research and fact-checking — it hunts primary sources and cross-checks them. Breaks your question into checkable claims, verifies each against independent sources, surfaces contradictions, and delivers a traceable, cited report — neutral, never a true/false verdict.
- [AI Quality Check](https://skills-for-ai.com/skills/ai-quality-check/) — Productivity · v1.1.0: AI Quality Check is an AI-output quality-check skill: it fact-checks and reviews AI-generated output — ChatGPT/Claude answers, project plans, prompts, text, summaries or code — for hallucinations, gaps, risks and real usability, then makes it better. Eval, not vibes: claim ledger, hallucination & AI-fluff check, score + traffic light, prioritized fixes and the next best prompt. Nine modes incl. fact-check (SIFT), red-team / agent security (OWASP LLM) and a leftover scan.
- [AI Signal Check](https://skills-for-ai.com/skills/ai-signal-check/) — Writing · v1.0.0: AI Signal Check is an AI-writing-pattern check skill: it analyzes text for AI-typical language, structure and style patterns and explains, fairly, *why* it reads artificial, generic or too smooth. Not an "AI detector": no authorship verdict, no percentage. Instead an assessment category, signal strength 1–10, confidence, false-positive risk, flagged passages with an alternative explanation, ranked origin hypotheses and an editorial recommendation — for website, cover letter, LinkedIn, support and editorial use.
- [AI Transparency](https://skills-for-ai.com/skills/ai-transparency/) — Business · v1.0.0: AI Transparency is an AI skill for AI content labelling, disclosure and machine marking that, for a given AI content, system, chatbot, campaign or platform post, works out whether a labelling duty can apply, **who** is responsible, **which** current rule governs it, whether the platform already offers a label — and whether that is enough. It covers the EU AI Act (Art. 50), DACH, international modules, platform functions and C2PA. Built responsible: source-first & verify-live, never "legally safe/guaranteed", not legal advice.
- [Brand Voice Guardian](https://skills-for-ai.com/skills/brand-voice-guardian/) — Marketing · v1.0.0: Brand Voice Guardian is an AI skill that learns, documents, applies, reviews and protects your brand's voice — so AI content sounds like your brand, not like generic AI. It builds a persistent brand-voice.profile.md, reviews new content for brand fit, tone, terminology, channel and AI-generic risk, and rewrites copy on-brand. Not a rewrite tool: a brand-governance layer for AI workflows.
- [Color Matchmaker](https://skills-for-ai.com/skills/color-matchmaker/) — Creative · v1.0.0: Color Matchmaker is an AI skill for color palettes and color schemes — it finds colors that work together, gives each one a clear role (background, text, button, accent, status), checks contrast and accessibility deterministically, and shows the palette in a real mockup. It advises people with no color knowledge in plain language — not a random generator, not a logo generator.
- [Decision Board](https://skills-for-ai.com/skills/decision-board/) — Business · v1.0.0: Decision Board is a decision-making skill that runs a structured panel of experts, stakeholders and critical counter-voices. Instead of one AI answer you get a real second opinion: independent first judgments, a genuine debate, an assumption and risk check, a minority report and a clear, traceable recommendation.
- [Digital Identity Architect](https://skills-for-ai.com/skills/digital-identity-architect/) — Development · v1.0.0: Digital Identity Architect is an AI skill for a website's digital identity — structured data, Schema.org/JSON-LD and the knowledge graph. It first understands a site's real entities, models an entity graph with stable @ids, then implements the markup framework-correctly and validates it — honestly, with no rich-result hunting. Not about digital identity in the eID/login sense.
- [Government Navigator](https://skills-for-ai.com/skills/government-navigator/) — Productivity · v1.0.0: Government Navigator is an international public-services & life-admin navigation skill: it turns a life event ("I'm moving abroad", "I need a visa", "I got an official letter") into a clear, ordered route — the responsible authority, the official source, the forms, the documents, the appointment, the deadlines and the next step. It covers visas/immigration, travel authorizations (ETIAS/EES/ESTA/eTA/UK-ETA), relocation, work/study, family, benefits, business setup, apostille/legalisation, official letters and government accounts — worldwide. Built to be responsible, not confidently wrong: official-source-first, never invents fees/deadlines/URLs (verify-live), no guarantee, mandatory scam layer. Not legal advice.
- [Happy Ending](https://skills-for-ai.com/skills/happy-ending/) — Productivity · v1.0.0: Happy Ending is an AI skill for closing AI work sessions cleanly, turning the chat into the valid project state: final decisions, open tasks, a memory patch and a copy-paste next-session prompt. Its core is a Memory Safety layer, so discarded, canceled or superseded work is not mistakenly saved as the valid state.
- [Humanizer Pro](https://skills-for-ai.com/skills/humanizer-pro/) — Writing · v1.1.0: Humanizer Pro is an AI skill for reworking generic or AI-typical text that makes it more natural, concrete, credible and channel-fit — without distorting facts and without "beating" detectors. It spots clichés, buzzwords and over-smoothed AI structure, protects names, numbers and core claims (Meaning Lock), and rewrites for email, website, LinkedIn, cover letters, support and more — in your real voice or your brand voice.
- [Pain Miner](https://skills-for-ai.com/skills/pain-miner/) — Marketing · v1.0.0: Pain Miner is a voice-of-customer skill for pain mining: it finds the real problems, wishes, objections, buying motives and switch/churn reasons behind a product, industry, audience, brand, competitor or your own customer data — and turns them into product, marketing, sales and content decisions. Method-grounded (Jobs-to-be-Done, The Mom Test, Value Proposition Canvas, Kano, RICE), it preserves the customer's real language (verbatim, verified), labels every finding by confidence (backed/plausible/hypothesis/weak), and prioritizes instead of listing. Honest by design: hypothesis ≠ evidence, no vocal minority as truth, no fear-mongering.
- [Pain-to-Punchline](https://skills-for-ai.com/skills/pain-to-punchline/) — Marketing · v1.0.0: AI copywriting for marketing hooks, ad copy and campaigns: Pain-to-Punchline turns real problems and everyday frustrations into scroll-stopping hooks, headlines, punchlines and taglines — with method, not random jokes, and always landing on the product benefit.
- [Privacy Check](https://skills-for-ai.com/skills/privacy-check/) — Business · v1.0.0: Privacy Check is an AI skill for a structured data-protection pre-check of any project — it makes visible which data, purposes, jurisdictions, vendors, consents, retention periods and risks must be checked before you go live. Not just websites: apps, newsletters, giveaways, events, leads/CRM, communities, chatbots, AI agents, shops, courses, HR and automations too. It detects the project type and use cases, routes the relevant regimes (GDPR, ePrivacy, EU AI Act, UK, US state laws), flags high-risk hard, and delivers a risk traffic light, prioritized to-dos and an expert-review briefing. Not legal advice, not a final sign-off.
- [Sober Reply](https://skills-for-ai.com/skills/sober-reply/) — Writing · v1.0.0: Sober Reply is an AI skill for clear, safe replies in hard-to-write moments — a low-input, plain-text and safety mode that understands messy input, typos and half-formed thoughts when you're drunk, tired, stressed, sick or simply not in writing shape. It keeps replies short, asks only light questions, de-escalates messages and pushes risky actions like sending, posting, buying or deploying to a sober moment. With crisis & emergency protection and one firm rule: messy input never automatically means "drunk".
- [Social Preview Architect](https://skills-for-ai.com/skills/social-preview-architect/) — Marketing · v1.0.1: Social Preview Architect is an AI skill for Open Graph and social-share previews that plans, designs, checks and maintains the images and meta tags your website shows when links are shared on Discord, Slack, LinkedIn, WhatsApp, X and beyond. It never generates blindly: it first inspects the real page (logo, colors, theme, existing og: tags), then proposes a preview strategy for approval.
- [Token Waster](https://skills-for-ai.com/skills/token-waster/) — Creative · v1.1.0: Token Waster is an AI skill that lets you waste your tokens on a few small games, right in your AI chat. Quick minigames and a few longer save-driven ones, sharing one save system, an on-demand dashboard, a story-memory engine and a cross-game profile. The joke is anti-efficiency: spend your tokens on fun instead of saving them. Everything is single-player; to play with friends you swap a challenge code. Built honest: it promises only what works everywhere, and everything better is a bonus.
- [Website Doctor](https://skills-for-ai.com/skills/website-doctor/) — Development · v1.1.0: Website audit tool for SEO, security headers, Core Web Vitals, GDPR and AI visibility (GEO). Measures your site or local project for real and checks every rule live against the current official source — then delivers a prioritized, evidence-backed report and safe fixes.
- [Wiki Editor](https://skills-for-ai.com/skills/wiki-editor/) — Writing · v1.0.0: Wiki Editor is an AI wiki-editing skill that edits pages with the correct syntax (wikitext, Markdown, Confluence): it detects the wiki engine, understands the markup, preserves local templates and infoboxes, suggests internal links, plans images, builds tables and categories, and writes the edit summary.
