Superpowers Marketplace — Summary

Superpowers Marketplace is a curated plugin registry for Claude Code maintained by Jesse Vincent (obra), providing a single /plugin marketplace add endpoint that distributes the core superpowers plugin and a growing catalog of companion plugins (elements-of-style, superpowers-lab, superpowers-developing-for-claude-code, episodic-memory, superpowers-chrome, private-journal-mcp, double-shot-latte, claude-session-driver).

The marketplace itself ships no skills, commands, or hooks — its entire value is the marketplace.json catalog that points Claude Code's plugin system to the correct GitHub repositories for each plugin, with version pinning (strict: true) and source URL resolution.

Differs from superpowers (seed): The seed superpowers is the core plugin with 14 skills and a SessionStart hook. This marketplace repo is the distribution layer — it contains only .claude-plugin/marketplace.json and README, enabling /plugin marketplace add obra/superpowers-marketplace to make all obra plugins discoverable from a single registry endpoint.

Superpowers Marketplace — Since Superpowers (Seed Delta)

What This Adds Beyond the Seed

The superpowers-marketplace repo adds zero new skills or behaviors — it is purely a distribution registry.

New capability introduced

• A marketplace.json catalog with 9 plugins (as of version 1.0.13)
• Single endpoint: /plugin marketplace add obra/superpowers-marketplace installs all obra plugins into the Claude Code plugin registry

Plugins it references

Key observation

double-shot-latte (version 1.2.0) addresses a specific superpowers limitation: the core plugin's skills are designed to trigger automatically, but agents sometimes pause asking "Would you like me to continue?" This companion plugin uses Claude-judged auto-evaluation to suppress those interruptions.

episodic-memory addresses the seed's lack of cross-session memory by adding a local semantic search layer over past conversations.

superpowers-dev has an explicit strict: true and a warning: "YOU MUST UNINSTALL OTHER VERSIONS OF SUPERPOWERS BEFORE INSTALLING THIS."

Superpowers Marketplace — New Primitives

New Primitives vs. Seed

Zero new primitives at the repo level. The superpowers-marketplace repo contains:

• .claude-plugin/marketplace.json — plugin catalog
• README.md — human-readable catalog

No skills, commands, hooks, scripts, agents, or MCP servers.

Primitives in Referenced Plugins (not in seed)

The marketplace.json references plugins that do add new primitives beyond the seed:

episodic-memory (v1.4.2)

• New primitive type: External MCP server for semantic conversation search
• Fills the seed's cross-session memory gap

private-journal-mcp (v1.2.0)

• New primitive type: Local journaling MCP server with AI embeddings
• Multi-section entries: feelings, project notes, technical insights, user context, world knowledge

claude-session-driver (v3.0.0)

• New orchestration pattern: tmux-based worker session launcher
• Enables spawning and controlling other Claude Code sessions as workers
• This is the closest the superpowers ecosystem gets to true multi-agent orchestration infrastructure

double-shot-latte (v1.2.0)

• New hook pattern: PostStop hook that auto-evaluates whether Claude should continue
• Addresses the "Would you like me to continue?" interruption antipattern

superpowers-chrome (v3.0.1)

• New MCP mode: Chrome DevTools Protocol via either CLI commands or a single use_browser MCP tool
• Dual-mode (skill + MCP) design

The Marketplace Format

{
  "name": "superpowers-marketplace",
  "plugins": [
    {
      "name": "superpowers",
      "source": {
        "source": "url",
        "url": "https://github.com/obra/superpowers.git"
      },
      "version": "5.1.0",
      "strict": true
    }
  ]
}

The strict: true field enforces version pinning — plugins must be the declared version.
