What it does
skill-creator-plus is a Claude skill for auditing, building and refining other skills. According to the README, its checklist draws on Anthropic's skill-writing rules and guidance for Claude Fable 5, Opus 5.5 and Sonnet 5.5.The README describes AUDIT as producing a rule-by-rule report with file-and-line evidence and proposed fixes, NEW as starting with test prompts before creating a skill folder, and REFINE as rewriting a rule around its reason. The README tells the skill to wait for the user's choice before applying fixes.
The README lists the root SKILL.md, audit, authoring and testing references, a Python validator, a skill-scaffolding script and a deliberately broken example with report and validator output.
Who it is for
People who write or maintain Claude skills and want a rule-by-rule report on them.Example tasks
Audit a deploy skill against Anthropic's rules and read the report before choosing fixes.Check every skill in a skills folder and see what to fix first.
Turn a recurring job, such as weekly release notes, into a new skill.
Refine a skill that keeps forgetting a step, such as a date filter.
Run the validator on one skill folder or on every skill in a folder.
Getting started
For Claude Code, the README says to put the folder in your skills folder and name it skill-creator-plus. It gives one git clone command for all your projects and another for one project only. It adds that downloading the ZIP from GitHub and copying the folder there also works. For claude.ai, zip the folder with SKILL.md, references/, scripts/ and LICENSE, and upload it under Skills in settings. The README says you can leave out examples/. The README has the exact commands.Limitations
The README gives installation routes for Claude Code and claude.ai. For Claude Code, the folder is named skill-creator-plus and placed in a personal or project skills folder; on Windows, the README identifies ~/.claude as the .claude folder inside the user folder. For claude.ai, the README says to upload a ZIP under Skills in settings and enable code execution for the validator.According to the README, the validator requires Python 3.8 or newer, uses the standard library and works on Windows, Mac and Linux. The README distinguishes script-decided rules, candidates requiring Claude's contextual confirmation, and rules judged through reading. The README says its rules were checked against Anthropic's pages on 2026-10-05 and that the project is not affiliated with Anthropic. The repository can change at any time; check its README before you install.
