AI Agent Harness: Optimize Claude & Codex Workflows

AI Agent Harness: Optimize Claude & Codex Workflows

The AI Agent Harness skill organizes and routes tasks within AI agent workflows involving Claude Code and Codex tools. It effectively determines the appropriate runtime environment for specific requests, streamlining the process by focusing on the designated leaf skill after initial routing.

What this skill does

• Routes requests between an AI control harness and its Codex or Claude runtime.
• Supports design, refactoring, or recovery of control planes with agent-harness-engineering.
• Benchmarks, replays, diagnoses, and compares complete harness behavior using agent-harness-evaluation.
• Facilitates Codex workflow operations and diagnoses through `codex-cli`, addressing automation, task supervision, and lifecycle management.
• Manages Claude Code workflow operations with claude-code, including print automation and session handling.
• Verifies operational schedules with scheduled-automation-runtime to ensure tasks were executed correctly.

Who it is for

This skill is designed for developers and teams working with AI coding agents such as Claude Code, Cursor, and Codex. It benefits those looking to optimize task routing, streamline workflows, and conduct robust evaluations of AI tool behaviors.

Use cases

• Developers seeking to route workflows dynamically across multiple AI agent platforms.
• Teams requiring in-depth evaluation and debugging of AI harness behaviors.
• Organizations needing verification of automated tasks scheduled via systemd, cron, or Windows Task Scheduler.

Technical details

• Integrates with Claude Code and Codex ecosystems for precise workflow management.
• Utilizes agent-harness-engineering and agent-harness-evaluation for design and analysis functions.
• Employs codex-cli and claude-code for operating specific runtime environments.
• Provides scheduling proof using scheduled-automation-runtime to confirm execution activities.
