Use when the user wants to build, scaffold, ship, or edit a Cadet plugin that bundles multiple surfaces (hooks, tools, skills, and more) into one installable package.

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

# Plugin Builder

Build on top of Cadet with plugins. A plugin bundles multiple surfaces into a single installable package that extends what an assistant can do.

Plugins are in beta. The peer-dep range you declare is what gets you load. Treat everything you write as something that can break between Cadet releases until 1.0 ships, and pin a real range.

## What is a plugin?

A plugin is a directory in the assistant's workspace (`<workspaceDir>/plugins/<name>/`) that groups different surfaces into one cohesive capability. The assistant can build plugins directly in this folder or install one from the community via the CLI:

```
assistant plugins install <name>
```

Plugins can also be discovered and managed from the Plugins tab in the app, or searched from the CLI with `assistant plugins search`. The catalog is a curated allowlist that the Cadet team approves and curates.

## The surfaces a plugin can bundle

A single plugin can contribute several different kinds of behavior. Each surface is discovered by convention from a named subdirectory. Missing directories are simply skipped, so a plugin contributes only what it ships.

How to install

The exact contents, by fingerprint

mdr add vargasjr-dev/mycadet-temp/plugin-builder@sha256:8f0475d57f8897ca

The line at the top of this page pins the label git:20261012.7e57fb4, 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.
