positronick — Claude Code plugin

Brings the Positronick Hub into your agent. Bundles:

• MCP server — wires positronick mcp serve (5 tools: soul_search, soul_show, soul_install, listing_search, listing_show).
• Skill (positronick) — teaches the agent the CLI: searching, reading, and installing souls and registry listings, the --json contract, and exit codes.

Prerequisite

The positronick binary must be on PATH:

curl -fsSL https://positronick.com/install.sh | sh

Install (Claude Code)

claude plugin marketplace add Positronick/positronick-plugin
claude plugin install positronick@positronick

Then the positronick MCP tools and the positronick skill are available in your sessions.

  .mcp.json                              # positronick mcp serve (stdio)
  skills/positronick/SKILL.md            # the skill (vendored — see below)
scripts/sync-skill.sh                    # re-vendor the skill from the CLI repo

Skill provenance

plugins/positronick/skills/positronick/SKILL.md is vendored verbatim from the canonical, CI-pinned source in Positronick/cli. That repo is the single source of truth (the skill is pinned to the CLI's Go contracts by tests). Do not edit the copy here — re-sync it after the canonical skill changes:

./scripts/sync-skill.sh   # pulls Positronick/cli@main

Other ecosystems

The same MCP server and skill are distributed beyond Claude Code (xAI Grok Build, Nous Hermes, the official MCP Registry, agentskills.io discovery). The staged artifacts and step-by-step instructions live in PUBLISHING.md and publishing/.
