This is third-party code. Review the repository files before installing.
What it does
skild works like npm, but for agent skills. `skild install` installs a skill from a GitHub URL, the `owner/repo/path` shorthand, a local path or a registry name such as `@publisher/skill-name`. Then come `list`, `info`, `update`, `sync` to fetch missing ones, `uninstall`, `validate` to check a skill folder and `init` for a new skeleton. Skills go to `~/.claude/skills` by default, the `-t` flag retargets to Codex, Copilot, Antigravity, OpenCode, Cursor or Windsurf, and `--local` installs into the project. Skillsets bundle several skills into one package, for example `@skild/data-analyst-pack`. Authors get `skild signup`, `login`, `push` to a Git repository and `publish` to the registry, while `skild search` queries the hub. `extract-github-skills` builds a local catalog from skills on GitHub.
Who it is for. People who keep many skills across several agents and want to install and update them with one command.
Good fit when
- A skill from GitHub goes into `~/.claude/skills` with one command.
- The same skill is needed in both Codex and Cursor.
- A role-specific set, such as for an analyst, installs as a pack.
- Your own skill is checked with `skild validate` and published to the registry.
Not a fit when
- Skills are installed by hand and there are few.
- Third-party code from a registry must not run on the work machine.
- A security review of skills before installation is needed.
Example request
Install the skill `anthropics/skills/skills/pdf` into Codex with skild, then list the installed skills.Limitations
Skills from the registry and GitHub are written by third parties and contain instructions and scripts your agent will receive: review the source before installing. `skild` installs files but does not rate skill safety or quality. Publishing to the registry needs a publisher account via `skild signup` and `login`. Codex, Copilot, Antigravity, OpenCode, Cursor and Windsurf are selected with the `-t` flag, and other agents are not described in the README. Installation goes through npm, so Node.js is required. The last commit dates from September 2026.
How to disable. Run `npm uninstall -g skild`. Installed skills are removed with `skild uninstall <skill>` or by hand from the agent skills directory.
FAQ
How do I install a skill into Codex?
With `skild install anthropics/skills/skills/pdf -t codex`. Add `--local` for a project install.
Where can skills be installed from?
From GitHub by URL or `owner/repo`, from a local folder and from the registry by `@publisher/skill-name`.
What are skillsets?
Packs that install several skills at once, for example `skild install @skild/data-analyst-pack`.
How do I publish my own skill?
Create a skeleton with `skild init`, check with `skild validate`, then `skild signup`, `skild login` and `skild publish`.
How do I update skills?
`skild update` for all or `skild update <skill>` for one.
