Build a plugin or adapter for a CLI tool using the abstract base class pattern. Covers defining the contract (static fields, required methods), choosing an installation strategy (symlink, copy, append-to-file), implementing detection, install/uninstall with idempotency, listing, auditing, and registering the plugin. Use when adding support for a new framework to a CLI installer, building a plugin system for any multi-target tool, or extending an existing adapter architecture.
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
# Build a CLI Plugin
Add a new plugin or adapter to a CLI tool's pluggable architecture using the abstract base class pattern.
## When to Use
- Adding support for a new target framework to a CLI installer
- Building a plugin system for a multi-target command-line tool
- Extending an existing adapter architecture with a new strategy variant
- Porting content delivery to a framework that uses a different file layout
## Inputs
- **Required**: Framework or target the plugin supports (name, config paths, conventions)
- **Required**: Path to the base class or plugin contract
- **Required**: Installation strategy: `symlink`, `copy`, `file-per-item`, or `append-to-file`
- **Optional**: Content types the plugin handles (e.g., skills only, skills + agents, full support)
- **Optional**: Scope support (project-level, global, both)
## Procedure
### Step 1: Define the Contract
The base class establishes the interface all plugins must implement:
```javascript
export class FrameworkAdapter {
static id = 'base'; // Unique identifier
static displayName = 'Base'; // Human-readable name
static strategy = 'symlink'; // Installation strategy
…Read the whole file at its exact version.
How to install
mdr add pjt222/agent-almanac/build-cli-plugin@sha256:7f9cb675cf59db66The line at the top of this page pins the label v1.0, 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.
