feat(plugin): expose repo as a marketplace with two installable plugins#14
Merged
Conversation
`/plugin marketplace add mittwald/agent-skills` failed because the repo only shipped a single-plugin manifest (.claude-plugin/plugin.json) and no marketplace catalog, so Claude Code could not find marketplace.json. - Add .claude-plugin/marketplace.json cataloguing both skills as plugins - Add per-skill .claude-plugin/plugin.json (single-SKILL.md-at-root layout), keeping the skills/ dirs in place so `npx skills add` and manual clone installs keep working - Drop the repo-root plugin.json that treated the whole repo as one plugin - Fix README install command: mittwald-zerodeploy-skill -> mittwald-zerodeploy Validated with `claude plugin validate .` (passes).

The registered marketplace name (the `@…` install suffix) comes from the `name` field in marketplace.json — there is no client-side alias at add time. Rename it from the generic `agent-skills` to `mittwald-agent-skills` so the origin is clear and it won't collide with other generic marketplaces. Install suffix is now `@mittwald-agent-skills`; README updated to match. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

/plugin marketplace add mittwald/agent-skillsfailed with:The repo shipped a single-plugin manifest (
.claude-plugin/plugin.json) but no marketplace catalog, so/plugin marketplace addhad nothing to read. The README's install commands could never resolve.Change
Turn the repo into a marketplace with two individually installable plugins:
.claude-plugin/marketplace.json— catalog namedmittwald-agent-skills, listing both skills as plugins (source: ./skills/<name>). The name is explicit rather than the genericagent-skillsso the origin is clear and it won't collide with other marketplaces (the@…install suffix comes from thisnamefield — there is no client-side alias at add time)..claude-plugin/plugin.json— each skill dir becomes a single plugin using the "oneSKILL.mdat plugin root" layout. Theskills/dirs stay in place, sonpx skills addand manual-clone installs keep working.plugin.json— it treated the whole repo as one bundled plugin and conflicted with the marketplace approach.mittwald-zerodeploy) and the install suffix (@mittwald-agent-skills).Validation
claude plugin validate .→ passesscripts/validate-skills.sh→ 2 skills passUsage after merge
