Install

Skills CLI

npx skills add extractumio/extractum-skills

Asks which skills and agents to install. Just one: npx skills add extractumio/extractum-skills --skill agent-browser — add -g for every project.

Claude Code

git clone https://github.com/extractumio/extractum-skillscp -r "extractum-skills/computer-use/agent-browser" ~/.claude/skills/

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

Plugin

/plugin marketplace add extractumio/extractum-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.

  • agent-browser

    Automate rendered or authenticated websites with agent-browser using a locally installed Chrome-family browser, dedicated persistent profiles, and non-default named sessions. Use for browser interaction, manual-login reuse, dynamic extraction, UI debugging, screenshots, network diagnostics, accessibility or performance checks, and repeatable web test flows. Prefer ordinary HTTP/web research when…

  • playwright-cli

    Browser automation for UI debugging, authenticated page scraping, data extraction, and test generation using playwright-cli. Use when the user needs to interact with web pages, debug UI issues, extract data from authenticated sites, scrape complex pages, or generate Playwright tests.

    computer-use/playwright-cli/SKILL.md on GitHub (opens in a new tab)
  • read-mailbox

    READ-ONLY search and reading of the user's local Apple Mail (Mail.app) mailboxes. Use when the user asks to find, read, summarize, or extract something from their email — search by subject/sender/recipient/content, list mailboxes, show a message, list or save attachments. Never modifies the mail store (no read-marks, no flags, no deletions).

  • claude-orphan-cleanup

    Find and terminate orphaned Claude Code CLI processes that consume CPU resources. Works on macOS and Linux systems.

    devops/claude-orphan-cleanup/SKILL.md on GitHub (opens in a new tab)
  • gh-repo-create

    Create a GitHub repository, configure SSH deployment keys, and set up git remote for the current folder. Works on macOS, Linux, and Unix systems.

    devops/gh-repo-create/SKILL.md on GitHub (opens in a new tab)
  • eco-exposure-map

    Build an evidence-based environmental exposure analysis for any address, neighbourhood or district in any country, and deliver it as one self-contained interactive multi-layer HTML map. It covers every major pollutant (NO2, SO2, CO, O3, NH3, H2S, PM10, PM2.5, black carbon, heavy metals As/Cd/Ni/Pb/Hg/Cr, benzene/BTEX, VOC, formaldehyde, PAH/benzo[a]pyrene, dioxins, PCBs), stating "no data" wherev…

  • gcloud-search-console

    Query Google Search Console (Webmasters) performance data from the CLI using gcloud-issued credentials. Use when the user wants to pull clicks, impressions, CTR, or position data for their sites — e.g. "top queries for example.com", "pages ranking for X", "search performance last week".

    domain-specific/gcloud-search-console/SKILL.md on GitHub (opens in a new tab)
  • gcloud-setup

    Install and authenticate the Google Cloud CLI (gcloud, gsutil, bq) on macOS. Use when the user needs to set up gcloud from scratch, re-authenticate, add OAuth scopes for a specific Google API (Search Console, Drive, Sheets, etc.), or fix Application Default Credentials (ADC) issues.

    domain-specific/gcloud-setup/SKILL.md on GitHub (opens in a new tab)
  • product-analysis

    Comprehensive product analysis and competitive intelligence research. Produces a detailed analytical report covering value proposition, market positioning, features, pricing, technology stack, strengths, weaknesses, and competitive landscape for one or more products. Use when the user wants to evaluate, compare, or deeply understand products, SaaS tools, platforms, or services.

    domain-specific/product-analysis/SKILL.md on GitHub (opens in a new tab)
  • promotion-research

    Promotion & distribution research agent. Produces a prioritized list of 50+ specific platforms, directories, communities, and channels where a website can be promoted. Use when the user wants to find where to promote a product, SaaS, tool, or website for organic growth, backlinks, and targeted traffic.

    domain-specific/promotion-research/SKILL.md on GitHub (opens in a new tab)
  • bdd-spec

    Create or update implementation-ready Markdown feature specifications with acceptance criteria and Given/When/Then scenarios. Use for specs, PRDs, requirements documents, BDD, or Gherkin requests.

    general-purpose/bdd-spec/SKILL.md on GitHub (opens in a new tab)
  • code-review-cc

    Multi-agent review of the current diff (or a PR/MR number, branch, or file target) for correctness bugs plus reuse, simplification, efficiency, altitude, and conventions cleanups, at a selectable effort level. Low/medium surface fewer, high-confidence findings; high/xhigh/max widen coverage (language pitfalls, security, concurrency, wrapper correctness) and may include uncertain findings. Use whe…

  • mac-notification-claude-code-config

    Configure native macOS notification banners for Claude Code events (Stop, PermissionRequest, Elicitation) via terminal-notifier hooks, for both local macOS and remote Linux/tmux -CC setups bridged through iTerm2 Triggers. Use when the user asks to enable macOS notifications for Claude Code, be pinged when long tasks finish, get alerts for permission or MCP input prompts, or set up the iTerm2 Trig…

  • make-mvp

    Plan, prioritize, and sequence implementation work so every iteration ends with a working version the end-user can already benefit from. Applies a "progressive JPEG" principle — start with a thin core scaffold that already delivers real value, then add features in order of user-visible value. Bugs in already-shipped functionality come first; engineering for hypothetical future steps is rejected.…

  • scrutinizer

    Produce a complete, navigable project-state documentation set for any software project (mobile, web, desktop, backend, or monorepo) — architecture, data, flows, API, tests, security, state/sync, performance, observability, platform parity, config, and health. Use when the user wants a full-codebase audit, architecture documentation, an onboarding "helicopter view", a regenerable project snapshot…

  • simplify-code

    Review the changed code for reuse, simplification, efficiency, and altitude cleanups, then apply the fixes. Quality only — it does not hunt for bugs; use /code-review for that.

    general-purpose/simplify-code/SKILL.md on GitHub (opens in a new tab)
  • start-a-project

    Scaffold or update a project to match the standard CLAUDE.md structure — root CLAUDE.md, docs/ tree (architecture, source-map, testing trio, workflow, gotchas, deploy, api), docs/ephemeral/ working area, and .claude/ agent + skill stubs. Use when starting a new repo, adopting the standard layout in an existing repo, or repairing a partial scaffold. Skips existing files unless --force.

  • tms

    Connect to a remote tmux session over SSH using iTerm2's native tmux control mode (-CC), creating the session if missing and detaching any stale client. Works on macOS with iTerm2.

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.
