BUILD_SKILL.md▌
free draft generator · Claude Code · Cursor · skills registry
Use this page when you want a paste-ready SKILL.md without starting from a blank file: we interview you for purpose, triggers, and output shape, then return structured Markdown (frontmatter + body) you can drop into .agents/skills/ or your Claude Code skills folder.
Generate your draft
The API uses an excerpt of Anthropic's skill-creator guidance plus GPT-4o-mini. For background, see what are agent skills? and the FAQ below.
What this free tool does
explainx.ai/create/skill is a free SKILL.md generator for Claude Code, Cursor, and other hosts that load agent skills. In one sentence: you describe what the skill should accomplish and when it should run; we return structured Markdown with frontmatter so your coding agent can use progressive disclosure—light metadata for discovery and a full body when the task matches.
How it works
- Answer the form: purpose (20+ characters), trigger contexts, and expected output format.
- The API loads a trimmed skill-creator reference excerpt and asks GPT-4o-mini to emit a single valid SKILL.md.
- Copy or download the draft, edit for your repo, then commit under your skills directory.
Skills vs one-shot prompts vs MCP
| Approach | Best for |
|---|---|
| SKILL.md skill | Repeatable workflows, team standards, trigger-aware playbooks |
| Long chat prompt | Single session, exploratory tasks, no reuse |
| MCP server | Live tools, APIs, databases—side-effecting capabilities |

Why structure matters for humans and AI answers
Clear headings, a direct answer up front, and explicit FAQs help both search engines and generative search surfaces cite accurate summaries. Your generated SKILL.md should do the same: a pushy but honest description in frontmatter (when to load the skill) plus imperative steps reduces under-triggering and confusion—an idea emphasized in public skill-authoring guidance.
FAQ
- What does the explainx.ai SKILL.md generator do?
- It turns a short interview (purpose, trigger phrases, output shape) into a paste-ready SKILL.md draft. The server runs OpenAI GPT-4o-mini with an excerpt of Anthropic’s public skill-creator methodology so the file follows common agent-skill structure: YAML frontmatter (name, description), imperative workflow steps, examples, and constraints—without you writing the boilerplate from scratch.
- Is this the same as publishing a skill on the registry?
- No. This page only helps you author a local SKILL.md. Listing on explainx.ai still requires a Git repository and the submit flow at /submit after your skill is ready for review.
- Which AI model powers the generator?
- Requests use gpt-4o-mini via the OpenAI API. Output quality depends on how clearly you describe triggers and outputs; treat the result as a first draft to edit before production use.
- Where should I put the generated SKILL.md?
- Common layouts are .agents/skills/<skill-name>/SKILL.md (portable) or .claude/skills/<skill-name>/SKILL.md for Claude Code. Cursor and other hosts may use similar folders—check your product version for the exact path.
- How is a skill different from a long prompt or from MCP?
- A skill is a reusable, versioned instruction package (often SKILL.md plus optional references). A one-off prompt is not reusable across sessions. MCP servers expose tools and resources to the host; skills shape how the model plans and explains work. Many teams combine both.
- Does this replace the skill-creator skill in Claude Code?
- No. The bundled reference mirrors key parts of skill-creator so the web generator stays aligned with that guidance. Inside Claude Code you can still install the full skill-creator for iterative evals, packaging, and advanced workflows.
