horizondesk-sdk 1.4.0

SDK and CLI for building Horizon Desk AI Plugins

Horizon Desk SDK v1.3.0 🚀

The official Python SDK for building, testing, and publishing plugins for Horizon Desk.

What's New in v1.3.0

• Externally Hosted Plugins: Support for plugins hosted on custom local ports (e.g., Flask, Django backends) using the hosted_url manifest field.
• Package Renaming: The SDK is now officially horizondesk_sdk.
• Strict Navigation Policy: Built-in support for the new Horizon Desk security model which forces external links to the system browser.

Installation

pip install horizondesk_sdk

Quick Start

1. Initialize:

   horizondesk_sdk init MyPlugin
   

2. Develop: Edit main.py and add your tools. Use HorizonPlugin to register them.

3. Link UI: Set custom_ui=True and provide a custom_ui_path (for static HTML) or hosted_url (for Flask/Django).

Security & Best Practices

• SecretStorage: Never hardcode API keys. Use SecretStorage.get_secret("MY_KEY").
• PII Redaction: Use SecretStorage.redact_pii(text) to sanitize data before sending to external LLMs.
• Timeouts: Always use timeout= in network requests (e.g., requests.get(url, timeout=10)).
