Skill Builder (build-skill)

A meta skill that interviews you and writes a complete, standards-compliant Claude Code SKILL.md.

Dev & CodingIntermediate★ 319⑂ 36AI score 8/10Last updated: Aug 12, 2026

What it does

  • Turns a description of a workflow into a finished, ready-to-use SKILL.md file.
  • Classifies your input as minimal, medium, or rich, then asks only the questions still missing (intent, invocation mode, arguments, supporting files, scope).
  • Scans .claude/skills/ for overlapping skills and warns you before creating a duplicate.
  • Restricts frontmatter to actually supported fields and explicitly rejects unsupported ones like allowed-tools, model, context, and hooks.
  • Flags YAML traps, such as argument-hint needing a plain string rather than bracketed array syntax.
  • Runs a self-critique checklist (trigger conditions, no em-dashes, <DO_NOT_TOUCH> / <MAY_EDIT> zones), then writes the file and prints a summary card on approval.

Who it's for

  • Developers who build Claude Code skills often and want consistent structure every time.
  • Tech leads standardizing skill-authoring conventions across a team.
  • Newcomers who want a slash command but don't know the frontmatter rules yet.

Examples

  1. "Build a skill that drafts release notes" → it asks about arguments and invocation, then drafts release-notes.
  2. "I want a /pr-review slash command" → generates a user-only skill with disable-model-invocation: true.
  3. Ask for tool restrictions or a specific model and it advises building an agent instead of a skill.

Install in Claude Code

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the .claude/skills/build-skill folder from the GitHub repo LukeRenton/explore-claude-code into my ~/.claude/skills/build-skill/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/LukeRenton/explore-claude-code.git && mkdir -p ~/.claude/skills/build-skill && cp explore-claude-code/.claude/skills/build-skill/SKILL.md ~/.claude/skills/build-skill/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal.
  2. Clone the repo: git clone https://github.com/LukeRenton/explore-claude-code.git
  3. Create the skill folder: mkdir -p ~/.claude/skills/build-skill (use your project's .claude/skills/ instead for project scope).
  4. Copy the file: cp explore-claude-code/.claude/skills/build-skill/SKILL.md ~/.claude/skills/build-skill/
  5. Restart Claude Code or start a new session.
  6. Test it with something like /build-skill a skill that summarizes meeting notes.
  7. Add your team's conventions inside the <!-- <MAY_EDIT> --> block at the bottom of the file.
