Claude Code mods: Minesweeper and testkit
My own harness, the tooling I run around Claude Code, comes with a custom trust score. That trust score decides whether I can leave the agent alone yet, without supervision or if it's in my best interest to babysit it.
This article discusses the development and testing of a custom mod for Claude Code, focusing on the implementation of a Minesweeper game and a test kit for ensuring mod functionality.
What happened
The article describes the creation of a Minesweeper mod for Claude Code, which includes a custom trust score system and a test kit for validating mod functionality. The mod allows users to play Minesweeper while Claude Code processes tasks, and the test kit ensures the mod works correctly across different versions of the platform.
Why it matters
The mod and its test kit are significant for AI developers and mod creators because they demonstrate how to integrate custom functionality with Claude Code while ensuring reliability and compatibility. The test kit provides a framework for validating mod behavior, which is essential for maintaining quality in AI tooling.
- Implementing a trust score system helps determine whether an AI agent requires supervision.
- Using a test kit with mock objects ensures mod functionality is validated before deployment.
- Keyboard focus management is crucial for ensuring user interaction with mods.
- Simulating user interactions with a mock clock helps test timing and focus retries.
- Game state tracking systems can enhance user experience by keeping track of progress.
The bigger picture
The mod and its test kit have a practical impact on AI developers and mod creators by providing a framework for integrating custom functionality with Claude Code. The test kit ensures that mods are reliable and compatible with different versions of the platform, which is essential for maintaining quality in AI tooling.
The article highlights the development of a Minesweeper mod for Claude Code, along with a test kit to ensure its functionality. The mod demonstrates how to integrate custom functionality with AI tools while ensuring reliability and compatibility.
Technical details
- The mod uses JavaScript/TypeScript hooks to interact with Claude Code's interface.
- The test kit simulates user interactions and validates mod behavior using mock objects.
- The mod includes a trust score system to determine whether the agent requires supervision.
- The test kit uses a mock clock to simulate timing and focus retries for keyboard interactions.
- The mod includes a game state tracking system to keep the best time between sessions.
FAQ
What is the purpose of the trust score in the mod?
The trust score determines whether the agent requires supervision or can operate independently.
How does the test kit ensure mod functionality?
The test kit uses mock objects and simulates user interactions to validate mod behavior.
What is the role of the mock clock in the test kit?
The mock clock simulates timing and focus retries for keyboard interactions.
How does the mod handle keyboard focus?
The mod uses a retry logic to request keyboard focus after opening the pane.
What is the purpose of the game state tracking system?
The game state tracking system keeps track of the best time between sessions.
