Install

Skills CLI

npx skills add BretFisher/skills

Asks which skills and agents to install. Just one: npx skills add BretFisher/skills --skill docker-pro — add -g for every project.

Claude Code

git clone https://github.com/BretFisher/skillscp -r "skills/skills/docker-pro" ~/.claude/skills/

Copies the docker-pro skill into ~/.claude/skills/ for every project (use .claude/skills/ for one project). Repeat for the other skills listed below.

Plugin

/plugin marketplace add BretFisher/skills

Run inside Claude Code if the repository ships a plugin marketplace, then pick plugins from /plugin.

Skills can run code on your machine — read the SKILL.md first.

What it does

In the author's own words, from each skill's SKILL.md.

  • docker-pro

    Create, edit, and modernize Dockerfiles, .dockerignore, Docker Bake files, and Compose files using Bret Fisher's strongly opinionated modern Docker + BuildKit rules. Use this skill whenever the user asks about a Dockerfile, containerizing or "dockerizing" an app, base image choice, digest/SHA pinning of image tags, multi-stage builds, BuildKit, build caching or secrets, .dockerignore, docker-bake…

  • gha-audit

    Audit the GitHub Actions workflows in this repo for security, speed, and correctness, and report findings with a proposed diff.

  • github-actions-workflow-pro

    Create, edit, audit, and speed up GitHub Actions workflows using Bret Fisher's opinionated DevOps rules. Use it when the user asks to create a workflow or CI/CD pipeline, edit or add a job to an existing `.github/workflows/*` file (even a one-line change), review or harden a workflow for security, speed up slow CI, publish a container image from CI, automate releases, or mentions GHA, action pinn…

  • screencapture

    Captures the user's macOS screen, a window, or a region with the built-in `screencapture` CLI, then reads the image so the agent can see what the user sees. Use it when the user asks to check how a native macOS app looks (SwiftUI, AppKit, Electron, Qt, Tk, Java Swing), verify a window rendered correctly after a build or code change, diagnose a visual bug they describe in a desktop app, confirm a…

  • super-linting

    Set up local development linting by picking the right linters for each file type a project uses, then recording them as required pre-commit checks in AGENTS.md / CLAUDE.md and a `make lint` target. Uses the super-linter project as the live source of truth for which linters are current and popular per language. Use this skill whenever the user wants to add, choose, configure, or standardize linter…

  • skill-creator

    Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, edit, or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.

Review before you install

A skill is a set of instructions and scripts your agent will follow, and it can run code on your machine. Read the SKILL.md and any scripts first — this listing is not a security review.
