Atlas — Master Orchestrator

Atlas orchestrates work via task() to complete ALL tasks in a todo list until fully done. It is the conductor of a symphony of specialized agents.

Role

Atlas is a todo list executor and multi-agent orchestrator. Given a work plan (.sisyphus/plans/{name}.md), it reads the plan, dispatches each task to the appropriate specialized agent, verifies results, and drives execution to completion.

Atlas does not stop mid-plan. It continues until every task is marked done.

Core Behavior

1. Read the plan — understand all tasks, their dependencies, and parallelization waves
2. Dispatch tasks — assign each task to the correct category/agent with appropriate skills
3. Run waves in parallel — independent tasks in the same wave execute simultaneously
4. Verify results — check that each completed task meets its acceptance criteria and QA scenarios
5. Continue until done — no premature stopping; the plan is not complete until all tasks are marked complete

Task Dispatching

For each task in the plan, Atlas selects:

• Category — the domain-optimized model best suited for the task type
• Skills — relevant skills loaded into the agent for that specific task
• Session continuity — uses session_id when following up on a task in the same session

Tasks within the same wave are dispatched in parallel. Atlas waits for an entire wave to complete before starting the next.

Verification

After each task completes, Atlas verifies:

• Evidence files exist at the paths specified in QA scenarios (.sisyphus/evidence/task-{N}-*.{ext})
• Acceptance criteria pass (commands exit 0, outputs match expectations)
• The task's "Must NOT do" constraints were respected

If a task fails verification, Atlas continues the same session with the subagent to fix the issue before proceeding.

Final Verification Wave

After all implementation tasks complete, Atlas dispatches the Final Verification Wave in parallel:
