askit-init-marketplace

Purpose

Scaffold and validate a distribution index that catalogs plugins, in each target's native format. create scaffolds the marketplace index per target; validate checks that every entry resolves to a real plugin and that versions are consistent. The two native formats and the entry shape are in references/marketplace-format.md.

When to use

When standing up a marketplace, adding a plugin to one, or validating marketplace entries.

create mode

1. Read the target agents and the plugin roster to catalog.
2. Scaffold the index per target: Claude Code .claude-plugin/marketplace.json; Codex .agents/plugins/marketplace.json (Standard sec 12). Each entry names the plugin, its source or path, and its version.
3. Pick the source kind that matches how the plugin is actually distributed: a bare path, url/github (with a sha to pin it), npm, archive (which requires a sha256), or git-subdir. The full table is in the reference.
4. If an entry has shipped under a previous name, record it in renames so consumers following the old name can be redirected.
5. Keep the catalog separate from any single plugin's manifest (a marketplace catalogs plugins; it is not itself a plugin).

validate mode

1. Each entry resolves to a real plugin (its source/path exists and carries a library.json).
2. Versions are consistent (an entry's version matches the plugin's library.json version; no dangling or duplicate entries).
3. No renames value collides with a live entry name or with another entry's renames.
4. For a whole-catalogue grade, run node scripts/evaluate.mjs <catalogue-root> (marketplace scope). It grades every locally-resolvable member at its own declared tier and its own Standard pin, and reports the cross-member defects no per-plugin run can see: colliding skill and command names, a catalogue entry that resolves to nothing, and a registry version disagreeing with the member's own manifest.

Scope

A marketplace catalogs plugins for distribution; it is a separate artifact from the plugins it lists (the marketplace-vs-plugin separation rule). The Standard registers a plugin at its first tagged release, not before (sec 12); the toolkit additionally reserves its own marketplace debut for its Gold v1.0.0 tag (Decision C, a product choice, not the normative rule). This skill scaffolds and validates the index at any tier; publishing an entry waits for that first tagged release. askit-init-plugin scaffolds a plugin; this skill scaffolds the marketplace that lists plugins.
