parallel-tasks¶

Run multiple tasks in parallel.

Description¶

The parallel-tasks prompt provides instructions for executing multiple independent tasks concurrently using Contree’s async execution capabilities.

Parameters¶

Parameter	Type	Required	Default	Description
`tasks`	string	Yes	-	Tasks to run (one per line)
`image`	string	No	`python:3.11-slim`	Base image to use

Generated Instructions¶

When invoked with:

{
  "tasks": "python test_unit.py\npython test_integration.py\npython test_e2e.py",
  "image": "python:3.11-slim"
}

Returns:

Run these tasks in parallel:

Tasks (one per line):
python test_unit.py
python test_integration.py
python test_e2e.py

Steps:
1. Ensure image `tag:python:3.11-slim` exists (import if needed)
2. Call `run` for each task with `wait=false` - make parallel tool calls
3. Collect all `operation_id` values
4. Use `wait_operations` to wait for all to complete
5. Report results from each task

Example Usage¶

Parallel Tests¶

{
  "prompt": "parallel-tasks",
  "args": {
    "tasks": "pytest tests/unit/\npytest tests/integration/\npytest tests/e2e/"
  }
}

Multiple Experiments¶

{
  "prompt": "parallel-tasks",
  "args": {
    "tasks": "python train.py --lr 0.001\npython train.py --lr 0.01\npython train.py --lr 0.1"
  }
}

Build Multiple Targets¶

{
  "prompt": "parallel-tasks",
  "args": {
    "tasks": "cargo build --target x86_64-unknown-linux-gnu\ncargo build --target aarch64-unknown-linux-gnu",
    "image": "rust:1.75"
  }
}

Implementation Notes¶

The agent should:

Ensure the image exists (check with list_images, import if needed)

Launch all tasks in parallel with wait=false:

// Make these calls in parallel
{"command": "python test_unit.py", "image": "tag:python:3.11-slim", "wait": false}
{"command": "python test_integration.py", "image": "tag:python:3.11-slim", "wait": false}
{"command": "python test_e2e.py", "image": "tag:python:3.11-slim", "wait": false}

Collect the returned operation_id values

Wait for all with wait_operations:

{"operation_ids": ["op-1", "op-2", "op-3"]}

Process and report results from each operation
