How to read these examples
Every good skill follows the same skeleton: a narrow job, a description that triggers at the right moment, and steps concrete enough to audit. Notice how small each scope is — the skills below each do one thing.
Coding and developer skills
The most mature category, because developers felt the gap first:
- React and Next.js best practices — Vercel’s engineering guidance packaged as a skill that activates whenever you write or review React code. Pattern: a style guide with rules and examples.
- Interface review — a skill that reviews UI code against interface guidelines when you ask for an accessibility or design audit. Pattern: a checklist with pass/fail criteria.
- Browser automation — a skill that drives a browser to fill forms, take screenshots, scrape pages and test web apps. Pattern: procedural steps wrapped around a tool.
- Planning with files — a skill that creates plan, findings and progress files for complex multi-step tasks. Pattern: a working method that keeps state across long sessions.
- Skill discovery — a meta-skill that finds and installs other skills when you ask for a capability. Pattern: routing and search over a catalogue.
Writing, research and content skills
Where skills save the most editing time:
- Content research and writing — a skill that researches, adds citations, improves hooks and iterates section by section. Pattern: a pipeline with intermediate checkpoints.
- Source-grounded Q&A — a skill that answers from a specific document library instead of general knowledge. Pattern: retrieval plus a strict citation rule.
- SEO and GEO optimization — paid skills like Agensi’s GEO-SEO Suite coach teams on structuring content for search and AI answers. Pattern: domain expertise with frameworks.
- Local SEO audit — a packaged audit that checks a business’s search presence step by step. Pattern: expert questionnaire turned into a repeatable audit.
Media and video skills
Small skills that produce visible output quickly:
- Programmatic video — best practices for building videos in React, activated when you create video content in code. Pattern: framework conventions bundled with examples.
- Viral video cloning — CloneCut, the Seedance 2.0 agent that remixes a source video by swapping characters, products and backgrounds, is the top-selling video skill on Capafy AI. Pattern: a production workflow with clear inputs and outputs.
- Retention prediction — HookAce scores the first six seconds of a short video for hold rate. Pattern: a single measurable metric with actionable advice.
Trading and market research skills
A fast-growing niche where the skill replaces hours of manual scanning:
- Serenity Stock Tracker — turns Serenity’s public X posts into a daily report with every stock mention tagged bullish, bearish or neutral, plus stance history (1,748 sold on Capafy AI). Pattern: a public source turned into a structured daily digest.
- Alpha Consensus — tracks top public market voices and builds a consensus dashboard of who is bullish, bearish or neutral on the same stock. Pattern: many sources, one comparison table.
- TV Radar — a one-command technical read on any symbol: trend or range, moving averages, and conflicting signals flagged. Pattern: a jargon-heavy analysis translated into plain language.
The pattern behind all fifteen
Line them up and the common DNA is obvious: a narrow job, a trigger description, numbered steps, a defined output, and one or two examples of good work. None of them needed a new model or a new app — just expertise written down carefully in the open SKILL.md format.
That is the invitation. Pick the job you already do best, write it down, and you have skill number sixteen.
Run them, then build your own
On Capafy AI these packaged skills run as agents in the browser — sign in with Google, press Run, nothing to install. Browsing is free, and several agents cost nothing at all, which makes the marketplace the fastest way to see what a good skill feels like before writing your own.
And when yours is ready, publish it: you keep 80% of every sale, with payments and the runtime handled for you.
