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

# Plugins — Agent Instructions

Rules for code under `assistant/src/plugins/`, including the first-party default plugins in `defaults/`. For authoring or scaffolding a plugin (default or external), follow the `plugin-builder` skill (`skills/plugin-builder/`) — it documents the directory layout, hook contracts, and the `@vellumai/plugin-api` surface.

## Plugin Self-Containment

A plugin owns its state end-to-end. Everything a plugin persists lives in its own storage directory and is created, maintained, and cleaned up through the plugin's lifecycle hooks — never through the assistant's global persistence layer.

- **Storage location**: all durable plugin state lives under `InitContext.pluginStorageDir` (`<pluginDir>/data/` for installed plugins; `<workspaceDir>/plugins-data/<name>/` for defaults and standalone workspace hooks). Do not write plugin state anywhere else in the workspace.

How to install

The exact contents, by fingerprint
mdr add vellum-ai/vellum-assistant/assistant/src/plugins/AGENTS.md@sha256:b00cb0b81e5b61db

The line at the top of this page pins the label git:20260910.795a164, 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.
