**[Live showcase site →](https://cc-marketspec.pages.dev)**

A **headless data standard + generator** for the *presentation* of a Claude Code plugin marketplace.

You describe a marketplace as data; `cc-marketspec` joins it with the native plugin manifests, derives what's already encoded there, validates, and emits a single **`.cc-marketspec/dist/manifest.json`** — a render-agnostic document any website can be built from. **It ships data, not design.** How the site looks is the consumer's.

Mental model: native layer vs presentation layer

Native (Claude Code defines): marketplace.json, plugin.json, .mcp.json, skills/*/SKILL.md · commands/*.md · agents/*.md frontmatter, hooks/hooks.json. Identity + structure. You maintain these anyway for the plugins to work.
Presentation (this standard): .cc-marketspec/catalog.yaml (marketplace-level) + .cc-marketspec/entries/plugin-.yaml (per plugin). Only what native can't express.

**Rule: presentation never restates native facts** — it references them or adds presentation value. The generator joins the two by marketplace plugin id, which must match the `plugin.json` name.
