I Built an Agent to Run Live Event Raffles (then tried to rig it)

The Lockbox Demo showcases how secure coding practices can be implemented in agent-based applications using the Keycard platform. Here’s an overview of its key features:

Secure Coding Practices

1. Task-Based Credentials: Each tool call gets a fresh, scoped credential issued just-in-time.
2. Policy Enforcement at Issuance: Policy is evaluated before every use to ensure that only authorized actions are permitted.

Key Features of the Demo

• Real Event Raffles: The demo operates real event raffles, demonstrating its practical application beyond being a mere demonstration tool.
• Secure Secret Management: Secrets and API keys are managed using Keycard's CLI and vault system, ensuring no secrets are stored in plaintext or shell history.
• Dogfooding: Internal use of the demo provides direct feedback into product development.

Technical Implementation

1. Keycard CLI (keycard run): Manages just-in-time secret resolution and task-based credential lifecycle.
2. Keycard TypeScript SDK: Implements the same secure credential lifecycle for end-user-facing components.

Example Usage

• Secret Management:
