niksi: skills manager for coding agents

[![release](https://img.shields.io/github/v/release/osrim/niksi)](https://github.com/osrim/niksi/releases) [![checks](https://github.com/osrim/niksi/actions/workflows/checks.yml/badge.svg)](https://github.com/osrim/niksi/actions/workflows/checks.yml)

`niksi` installs, updates, and links community skills into your coding agent. `add` and `update` scan every file before writing it and record what you installed in `niksi-lock.json`. `install` verifies that record, so your team runs the same reviewed skills.

The command is `nik`.

Features

Pick what you install: nik add owner/repo lists the skills in a repository and lets you choose.
One install, every agent: Claude Code, Codex, Cursor, Gemini CLI, GitHub Copilot, OpenCode, Windsurf, Amp, Kiro, Cline, Qwen Code, and every other agent that reads .agents/skills. Each skill is stored once and symlinked into every skills directory.
Reviewed updates: nik update compares each installed skill with its source and shows the diff before it changes anything.
Dependencies: skills that depend on other skills from the same source are detected, and nik add offers to add them too.
Security scan: add and update scan every file before it is written. A critical finding stops the install until you approve it. See Security scan.

Install

[Homebrew](https://brew.sh), on macOS or Linux:

brew install osrim/tap/niksi

Or [npm](https://www.npmjs.com/package/niksi):

npm install -g niksi

Or run it without installing:

npx niksi add owner/repo

Or download the binary for your platform from the [latest release](https://github.com/osrim/niksi/releases/latest) and put it on your `PATH`. `niksi` needs `git`. For CI, see [Commands](docs/commands.
