Third-party skill packs
Operator OS does not ship other people's code. This page links to the packs worth installing and gives the install command. Install what you need; skip the rest. Pick one owner per job (see docs/03-skills.md).
Marks: "(verified)" = source and command were checked against a working setup. "(verify)" = check the repo README before running.
Ordered by how much they were used in real work. The first five are the default install.
| Pack | What it gives you | Source | Install |
|---|---|---|---|
| superpowers | Process skills: brainstorming, writing plans, subagent-driven development, executing plans, TDD, systematic debugging, parallel agents, git worktrees, code review, finishing a branch, writing skills. The backbone of the workflow. | https://github.com/obra/superpowers (verified; also listed in the official marketplace) | In Claude Code: /plugin install superpowers@claude-plugins-official (verified) |
| gstack | browse headless browser (open pages, click flows, screenshots, console errors), setup-browser-cookies, office-hours, plan reviews (CEO/eng/design), ship and deploy flow, retro, safety guards (/careful, /freeze). Needs Git and Bun. |
https://github.com/garrytan/gstack (verified) | git clone --single-branch --depth 1 https://github.com/garrytan/gstack.git ~/.claude/skills/gstack && cd ~/.claude/skills/gstack && ./setup (verified from its README) |
| impeccable | Frontend design skill: critique, polish, typography, layout, color, motion, accessibility for real UI. | https://github.com/pbakaus/impeccable (verified, Apache-2.0) | npx impeccable install (choose Claude Code, global), then /impeccable init in a project (verified from its README) |
| Matt Pocock skills | grilling / grill-me (interview until shared understanding), diagnosing-bugs, tdd, prototype, research, domain-modeling, handoff, git guardrails. |
https://github.com/mattpocock/skills (verified) | npx skills@latest add mattpocock/skills or /plugin install mattpocock-skills (both from its README; verified) |
| frontend-design (Anthropic official) | Guidance for distinctive, non-template UI. | Marketplace anthropics/claude-plugins-official (verified) |
/plugin install frontend-design@claude-plugins-official (verified) |
| Other official plugins | code-review, code-simplifier, feature-dev, github, context7 (library docs), claude-md-management, claude-code-setup. |
Marketplace anthropics/claude-plugins-official (verified) |
/plugin install <name>@claude-plugins-official (verified) |
| dataviz, artifact-design, update-config, claude-api | Chart and dashboard design rules, publishing pages as artifacts, settings/hooks editing, building on the Claude API. These ship with recent Claude Code or claude.ai builds rather than a separate pack, so there is nothing to install if your build lists them. | Built into Claude Code / claude.ai (check by typing / and looking for the name) |
No install command (verify in your build) |
| firecrawl | Web scrape, search, crawl, map to clean markdown; parse local PDFs/DOCX. Needs a Firecrawl API key. | Official marketplace listing (verified); vendor site firecrawl.dev | /plugin install firecrawl@claude-plugins-official (verified) |
| The Agency agents pack | ~150 role-based subagents (UI designer, SEO specialist, security engineer, sales coach...) and a multi-agent "NEXUS" playbook. Lives in ~/.claude/agents/. |
https://github.com/msitarzewski/agency-agents (verified, MIT) | brew install --cask msitarzewski/agency-agents/agency-agents (desktop app), or clone and run ./scripts/install.sh --tool claude-code (verified from its README) |
Operator OS also ships two skills of its own that complete the stack: write-professional and verify-before-done (in this repo's skills/). Everything else here is linked, not copied.
Add the official marketplace once
/plugin marketplace add anthropics/claude-plugins-official(Usually already present in new installs. Check with /plugin.)
Rules for packs
- Link and install only. Do not copy a pack's files into this repo.
- Plugins are per account. Installing under one
CLAUDE_CONFIG_DIRdoes not install it under another. Repeat the install per account, or keep packs as plain skill folders in a shared pool (see doc 03, Advanced). - One owner per job. If two packs both offer "review a PR" or "debug a bug", pick one and remove or disable the other. Overlapping skills fire unpredictably.
- Read before you trust. A skill is a prompt that can run commands. Skim
SKILL.mdand any scripts before installing something from a stranger. - Pin when it matters. Vendored git clones update when you
git pull. Note the commit you tested.
