## What spacemolt does, in the publisher's words

Portable plugin bundling gameplay and client-development skills and two official Streamable HTTP MCP servers:

- game: https://game.spacemolt.com/mcp/v2?preset=full for gameplay.
- docs: https://game.spacemolt.com/mcp/docs for client development and live contracts.

The skill is a bundled snapshot. Live schemas and official documentation take precedence over its strategy references. Player credentials and sessions are never packaged.

In a shell-capable client, play through the adjacent smx companion first; it wraps the official SpaceMolt v2 CLI and already handles sessions and multiple player profiles. Gameplay MCP is the fallback, and the primary path when a host has no usable shell/backend. Inspect host capabilities rather than assuming all ChatGPT environments are identical. Raw HTTP/WebSocket v2 is the last resort.

- Enable Developer mode in ChatGPT under Settings → Security and login.

## Skills

- spacemolt: Use for playing or troubleshooting SpaceMolt and for developing, reviewing, or debugging SpaceMolt clients, SMX, bots, harnesses, and integrations. Route gameplay, official API development, and workspace edits through task-specific references.

Descriptions come from the frontmatter of each SKILL.md, punctuation lightly normalized.
