What is BA in Claude Code?

BA is a task tracking skill for Claude Code that allows users and AI agents to manage work items, track progress, and coordinate tasks using a simple CLI interface.

How does BA handle multiple agents?

BA uses a session-based ownership model where agents must claim an issue before working on it, preventing multiple agents from accidentally duplicating efforts on the same task.

Why do I need a SESSION_ID for BA?

The SESSION_ID identifies the current worker. Claude Code provides this automatically in active sessions to ensure that 'claim' and 'finish' operations are correctly attributed.

Where are the tasks stored?

All tasks are stored locally in a .ba/issues.jsonl file. This format is human-readable and git-friendly, making it easy to track changes and resolve conflicts via version control.

Can BA handle task dependencies?

Yes, you can use the 'ba block' command to create dependencies. Issues will not appear in the 'ready' queue until all of their blocking requirements are marked as closed.

Productivity & Workflow

Manages task lifecycles and multi-agent coordination within Claude Code sessions using a lightweight, ownership-based tracking system.

BA (Task Tracker) is a specialized tool designed for orchestrating work between AI agents and human developers within a coding environment. It provides a git-friendly, JSONL-backed system to track issues, manage priorities, and define dependencies directly from the command line. By enforcing session-based ownership, BA prevents concurrent modification conflicts and ensures that every 'in-progress' task has a clear owner. It is particularly useful for complex projects where Claude needs to maintain a persistent state of progress and understand the next logical step in a development workflow.
