Agent Harness Skill

Automates the long-running agent workflow from Anthropic's engineering blog. Manages feature lists, progress tracking, and session orchestration across multiple Claude Code sessions.

Commands

/harness-init

Initialize a new project with:

• feature_list.json — comprehensive feature tracking
• claude-progress.txt — cross-session progress log
• init.sh — development server startup script
• .harness.json — harness configuration

/harness-run

Start a coding session. Reads progress, picks the next feature, and follows the incremental development workflow.

/harness-status

Show current project progress: features completed, next features to implement, recent session history.
