Metaskill

Metaskill (github.com/xvirobotics/metaskill) is an open-source Claude Code skill with an unusually ambitious remit: rather than doing one job, it builds the infrastructure that does the jobs. Its tagline — “one skill to create them all” — is literal. From a single /metaskill command it detects your intent and generates one of three things: a complete multi-agent team, a single expert agent, or a standalone workflow skill. Standing up a multi-agent system by hand normally means hours of designing roles, writing system prompts, picking MCP servers, and defining how agents hand work between one another; Metaskill collapses that into a few minutes of guided generation.

What sets it apart is that team generation is research-driven, not template-driven. It runs a four-phase process — research (web searches for current team structures and best practices for your stack), build (writes CLAUDE.md, .mcp.json, four to six agents, a couple of automation skills, and language-specific coding standards), credentials (collects any API keys the chosen MCP servers need, with a skip option), and verify (lists every file and validates the config). Each team follows a sane orchestration pattern: a tech-lead on Opus coordinates specialists on Sonnet, a dedicated code-reviewer enforces quality gates, and every agent ships with “Workflow Discipline” — plan first, re-plan on failure, verify completion. Seven verified MCP servers (context7, playwright, filesystem, postgres, sequential-thinking, memory, github) are auto-wired, and ready-made React, iOS, and data-science example teams let you copy a working setup and learn by reading it.

Installation is a one-line curl into ~/.claude/skills/metaskill/, and the only hard requirement is an authenticated Claude Code CLI. For anyone who has wanted to try multi-agent workflows but stalled on the setup, Metaskill is the fastest on-ramp we have reviewed — a genuine meta-skill that pays for itself on the first team it builds.
