A skill is the smallest unit of the systems Koso builds for clients: your conventions, your voice and your guardrails, encoded so AI does the work your way every time. We build full libraries of them, wired into the agents your team already uses. [Book a free call ](/book)[All agents ](/agents) ## It Checks What Exists Before It Writes. Most generators write from a blank page. This one researches first: a directory scout queries the skills.sh public API for skills that already exist in your space, with their real install counts, while a pattern scout searches how the work is actually done well. Sometimes the honest answer is "install this proven one", and the page says so. Your skill is then designed and written against that evidence, personalised to the answers you gave. true: built recently, answered instantlyfalsefan out, both at onceskill saved for 30 days · 2 live builds per dayskill requestthe box on this pageIFcache checkbuilt in last 30d?intake-agentasks 0-3 questionsdirectory-scoutskills.sh prior artpattern-scouthow the work is doneskill-designerspec as strict JSONskill-writerstreams the fileSKILL.mddownload + installpostgresresults cacheyouanswers, or noneskills.sh apireal installsweb search2 queriesai modelstrict JSONai modelstreamed The real pipeline behind this page. Swipe sideways on a phone to follow the whole flow. ## What Lands In Your SKILL.md. Six parts, written to be followed by an agent rather than admired by a human. The one most generated skills get wrong is the first: a description that never triggers means the rest of the file may as well not exist. ### Trigger-tuned description The frontmatter line your agent reads to decide whether to load the skill. Written with the exact phrasings you would actually type, because a skill that never triggers is a skill that does not exist. ### When to use it The situations that call for the skill, addressed to the agent directly, so it activates on the real task and not on lookalikes. ### The workflow Three to six numbered steps in strict order: what to do, what each step produces, and what to check before moving on. ### Output format Exactly what the finished deliverable looks like: structure, sections, length, tone, with a template where one genuinely disambiguates. ### Hard rules The musts and nevers: what the agent may not do, and when it has to stop and ask you instead of guessing. ### What good looks like How the agent can tell the output is done well, and the single most common failure to avoid. Also your checklist for sharpening the skill later. ## Install It In Under A Minute. A skill is just a folder with a SKILL.md inside. Download the file, put it where your agent looks for skills, and it loads automatically whenever a task matches the description line. No build step, no account, no lock-in: it is your markdown to keep and edit. 1. 1 Download the SKILL.md The button under every finished skill, or the share link's download. 2. 2 Create the skill's folder Claude Code: .claude/skills// in a project, or \~/.claude/skills// for everywhere. Other agents name their own folder. 3. 3 Drop the file in and use it Ask for the task the skill covers; the agent loads it on its own. Sharpen the instructions after the first real run. Works with Claude CodeCursorGitHub CopilotGemini CLICodex CLI Any agent that reads the SKILL.md format, which is most of them now. The generated file never references a specific machine or account, so the same skill moves with you between tools and teammates. ## AI Skill Builder FAQ ### What is an AI agent skill? A skill is a folder of instructions an AI coding agent loads when a matching task arrives. The core is a SKILL.md file: a short frontmatter block with the skill's name and a trigger description, then the instructions themselves, the workflow to follow, the output format, and the hard rules. Claude Code popularised the format and Cursor, Copilot, Gemini CLI and most other agents now read it. Installing one is how you teach your agent to do a job your way, every time, without re-explaining it in every chat. ### What does this skill builder actually do? You describe the capability you want in a sentence or two. An intake agent reads it and asks at most three questions, and only the ones whose answers would genuinely change the skill: a specific request gets no questions at all. Then two researchers work in parallel: one searches the skills.sh public directory for skills that already exist in this space, with their real install counts, and one searches the web for how the work is actually done. A designer turns all of it into a spec, and a writer streams your complete SKILL.md, ready to download and install. ### How is this different from browsing skills.sh? skills.sh is a directory of existing skills, and this tool searches it and shows you what it finds, because installing a proven skill with thousands of installs is sometimes the right answer and we would rather say so. The difference is personalisation: a directory skill was written for everyone, so it encodes someone else's conventions, tone and workflow. This builder writes the skill for YOUR need, from your own answers, and tells you honestly what the closest existing skill covers and what it misses for your case. ### Is the skill builder really free? Why only two builds a day? Yes, free. Your first build needs no sign-in; after that we ask for a name and email, no password, no credit card. Live builds are capped at two per day because each one runs a multi-stage AI pipeline that costs real money to serve. Reading, sharing and downloading finished skills is never capped: a skill someone already built replays instantly from the saved result, and shared links stay free for everyone. If you need more than two custom skills a day, that is what Koso builds for clients. ### How do I install the skill it writes? Download the SKILL.md and put it in a folder named after the skill inside your agent's skills directory. For Claude Code that is .claude/skills//SKILL.md in your project, or \~/.claude/skills//SKILL.md to make it available everywhere. Cursor, Copilot and the other agents each have an equivalent folder; their docs name it. From then on the agent loads the skill automatically whenever a task matches the description line. ### Which AI tools can use the generated skill? Any agent that reads the SKILL.md format: Claude Code, Cursor, GitHub Copilot, Gemini CLI, OpenAI's Codex CLI and a growing list of others. The file is plain markdown with a small frontmatter block, deliberately portable, so the same skill moves with you between tools. The builder never writes machine-specific paths or personal account details into the file for exactly this reason. ### Why does the description line matter so much? The frontmatter description is the only line your agent reads when deciding whether to load the skill at all. A beautifully written skill with a vague description simply never triggers, which is the most common way skills fail. This builder treats that line as the hardest part of the job: it writes the description in third person, names the capability, and lists the concrete phrasings a user actually types, so the skill fires when it should and stays out of the way when it should not. ### Can I edit the skill after it is generated? Please do. The file is yours: plain markdown, no lock-in, no watermark. The best skills are grown, not generated in one shot: install it, run it on a real task, and sharpen the instructions where the output missed. The last section of every generated skill tells the agent what good output looks like, which is also your checklist for judging whether the skill needs another edit. ## Try The Other Agents.
