What it does
Carl Skills is a collection of the author workflows for Claude Code, Codex, OpenCode, OpenClaw and Hermes agents. The repository is built as a catalog: most of the 17 skills have their own repository, and here sit a description of what each is and is not for and an entry in `registry.json` with an install address. Among them are an AI news radar, the Luban skill review, Humanize PPT, WeChat Read book actions and a publisher of X articles. Three skills live in the repository itself: `skill-slimming` inventories installed skills, plugins and MCP and prepares a review page before cleanup, `carl-file-organizer` makes a report on the Downloads folder and the disk, `wechat-article-video-download` downloads videos from WeChat articles. Descriptions and documentation are in Chinese.
Who it is for. Claude Code and Codex users with dozens of skills and plugins who need order in them and workflows for content.
Good fit when
- Many skills are installed and it is unclear which are needed globally and which only per project.
- The Downloads folder is cluttered and a report is needed on where each file will go before moving.
- A daily radar of AI news from chosen sources is wanted.
- A video from a WeChat article has to be saved locally by an agent script.
Not a fit when
- One new skill needs installing: the cleanup is meant for sorting what has piled up.
- Skills must be removed in bulk without review: the skill requires a review and a plan.
- English descriptions are needed: the documentation is in Chinese.
Example request
Audit the installed skills, plugins and MCP, show the review page and delete nothing until I choose.Limitations
The repository is mostly a catalog: the source of most skills lives in their own repositories, and `registry.json` stores install addresses. The `skill-slimming` skill contains a review page, a state service and reference contracts, so it is installed as a whole folder rather than a single `SKILL.md`, and it does not work in single-file Hermes mode. The cleanup removes nothing without a plan and confirmation, and low usage alone is not a reason. Documentation is in Chinese. The last commit was made on 6 November 2026.
How to disable. Delete the skill folder from the agent skills directory, for example `skill-slimming` from `~/.claude/skills/`. The review page keeps the user choices locally and goes away with the skill.
FAQ
How do I install one skill from the set?
With `npx skills add LearnPrompt/carl-skills --skill skill-slimming -g`. It installs only the named folder and enables no other skills.
How do I install all skills at once?
Clone the repository and run `python3 scripts/install_all_hermes_skills.py --dry-run`, then with `--yes`. The first run only prints commands.
What does skill-slimming do?
It reads installed skills, plugins and MCP, scores them by source and real usage and prepares a review page. It deletes only by plan after your confirmation.
Where are the other skills?
In their own repositories. This repository holds a description for each and a `registry.json` entry with an install address.
Which agents do the skills work with?
Claude Code, Codex, OpenCode, OpenClaw and Hermes. Multi-file skills need a whole-folder install in Hermes.

README in short
The README, in Chinese, is built as a catalog: a table of 17 workflows with what each is for, installation of one or all skills and the principle that only skills with no separate home stay in the repository.
