Official Claude Code plugin.json schema reference and validation guide. Use when creating or troubleshooting plugin.json manifest files. Covers all fields, auto-discovery behavior, path formats, and common validation errors.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Claude Code plugin.json Schema Reference
Complete reference for Claude Code plugin manifest files.
## Minimal Valid plugin.json
For plugins using standard directory structures, this is all you need:

```
**Auto-discovery** will automatically load components from standard locations.

How to install
mdr add mikeparcewski/wicked-garden/plugin-json-schema@sha256:601f0fbf32060a31The line at the top of this page pins the label git:20260209.e735af7, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
