Lythoskill-Arena: Advanced AI Agent Skill Testing Suite

Lythoskill-Arena: Advanced AI Agent Skill Testing Suite

Lythoskill-Arena provides a structured environment for testing AI agent skills and comparing deck configurations. It uses native Agent tools to spawn parallel subagents, ensuring a reliable and non-intrusive testing process. The suite supports both single-deck tests and multi-deck A/B comparisons without the need for manual command-line operations, except for cross-player comparisons which require a CLI runner.

What this skill does

• Supports test play for skills and deck configurations using AI agents.
• Runs single-deck tests and multi-deck A/B comparisons through agent-orchestrated operations.
• Performs cross-player comparisons using a command-line interface (CLI) runner.
• Executes experiments in `/tmp`, avoiding pollution of working sets and ensuring no deck overwrites occur.
• Resumes interrupted runs from saved states, maintaining the integrity of parent deck setups.
• Explicitly sets working directories for subagents by inheriting the parent current working directory (CWD).

Who it is for

• Developers and software engineers utilizing AI coding agents such as Claude Code, Cursor, and Codex.
• Technical teams focused on the evaluation and optimization of AI agent skills.
• Analysts responsible for configuring and testing AI-driven systems in varied scenarios.

Use cases

• Evaluating the effectiveness of newly developed AI agent skills within controlled environments.
• Conducting systematic A/B testing for AI configurations to determine context-specific suitability.
• Comparing different AI agents like Kimi versus Codex to assess performance differentials.

Technical details

• Utilizes the native Agent tool for orchestrating subagent processes.
• Relies on Bun.spawn for cross-player comparisons using the CLI runner.
• Configures setup through a `arena.toml` file, ensuring systematic test management.
• Maintains temporary directories for testing, safeguarding committed work directories from unintended modifications.
