Claude Skill Creator

Claude Skill Creator turns a one-line description into a complete, ship-ready SKILL.md — the metadata-plus-instructions file that the agent runtime loads to teach Claude a new capability. It is a meta-skill aimed at developers who want to author their own skills but don't yet know the exact frontmatter fields, the description-writing conventions that drive reliable triggering, or how Anthropic structures the instruction body. Instead of copying a template and guessing, you describe the skill you want and get a structured file back.

When to use it

• You're writing your first skill and need a correct SKILL.md skeleton rather than a blank file.
• You have a working prompt or internal runbook and want to package it as an installable skill.
• An existing skill never triggers, and you suspect the description field is the problem.
• You want your team's skills to follow consistent naming, tool-allowlist, and section conventions.

How it works

The skill drives a short interview, then writes a single SKILL.md with YAML frontmatter and a Markdown body. It fills in:

• name — kebab-case identifier (e.g. invoice-parser).
• description — the trigger text. This is the highest-leverage field: it must say what the skill does and when to use it, including the phrases a user would actually type. The creator front-loads concrete triggers here rather than vague summaries.
• allowed-tools — an explicit allowlist (e.g. Read, Bash, Edit) so the skill only gets the tools it needs.
• Instruction body — numbered steps, an examples section, and edge-case notes, mirroring the layout Anthropic uses for its bundled skills.

Usage example

curl -fsSL --create-dirs -o ~/.claude/skills/skill-creator/SKILL.md https://claudeskil.com/skills/skill-creator/SKILL.md

# then, in a session:
> Create a skill that extracts tables from PDFs and writes them to CSV

# outputs ./pdf-table-extractor/SKILL.md:

---
name: pdf-table-extractor
description: Extract tabular data from PDF files into CSV. Use when the
  user mentions a .pdf and wants tables, rows, or "pull the data out of
  this PDF" exported to spreadsheet form.
allowed-tools: Read, Bash, Write
---
# PDF Table Extractor
1. Read the target PDF path from the request...

Tips & gotchas

• Spend your edits on description, not the body — triggering is decided almost entirely by that field. Include real user phrasings.
• Keep allowed-tools minimal. Adding Bash unlocks the shell; omit it for read-only skills.
• The name in frontmatter must match the directory name, or the skill won't load.
• Heavy reference material (schemas, long examples) belongs in sibling files the skill reads on demand, keeping SKILL.md lean.

FAQ

Where does the file go? Into a folder named after the skill; drop that folder into ~/.claude/skills/ (or .claude/skills/ inside a project) and Claude Code picks it up.

Can it fix an existing skill? Yes — point it at a current SKILL.md and ask it to tighten the description or trim the tool list.

Does it write the implementation code? No. It produces the SKILL.md instructions and metadata; any scripts the skill calls are added separately.
