Amazon Braket

Amazon Braket

Primitives

The vocabulary of a Braket workflow, and which reference to open for each.

Each reference carries the domain detail for its own area — field paths, key names, API shapes, and billing models.

Additional notes:

• Reservation — exclusive device access for a booked window. This skill covers reservations at pointer depth only: the billing model is in pricing.md, reservation-specific device limits such as service.reservationShotsRange are in devices.md, and the full model is in the reservations developer guide.
• Gate calibrations / pulse control — access native gate calibrations on QPUs and attach custom pulse sequences at run time. See devices.md for detecting support, and the pulse control developer guide for the full model.

Critical Rules

These rules apply to every Braket request, whatever it involves.

1. The Amazon Braket Python SDK (`pip install amazon-braket-sdk`, imported as `braket`) is the primary entry point. Prefer it for every operation including Braket API operations, and understand what it covers by reading the docs or inspecting the SDK's modules locally.

• Use local execution tools for running the Braket SDK, such as shell with python3 -c "<code>".

1. The AWS MCP server is recommended for executing any other AWS API calls in this skill, especially operations not present in the Python SDK, although not required. Note: the AWS MCP's run_script tool executes code in a minimal sandbox without Braket libraries, so prefer using other tools for code execution, especially when using the Braket SDK.

1. A small set of primitives composes every workflow — see Primitives for the vocabulary and the reference for each.

1. Devices, quantum tasks, and hybrid jobs are region-scoped, so fan out across every Braket region whenever you use the API, CLI, or boto3 to search for resources. The SDK handles fanout for you where it can — AwsDevice.get_devices searches QPUs in all regions.

Get the list of regions Braket supports from aws___get_regional_availability when the AWS MCP server is available, or from the supported devices and regions documentation. Resource ARNs containing a region may only be queried from that same region, otherwise you will see a ResourceNotFoundException.

1. Open the matching reference before you write code or answer. Use the Primitives table to find and read references. Note: A request that asks for several things, e.g. executing a series of circuits and controlling the cost thereof, may require reading multiple reference files.

1. Verify, never recall. Device ARNs and statuses, API signatures, supported features, and prices (and other values) all change and may post-date training data.

1. Confirm an SDK signature before you write code that calls it. Read it from the SDK reference docs.

If no available tool can reach them, get it from the installed SDK with shell:

    PAGER=cat python -c "import braket; help(braket)"       # subpackages: ahs, circuits, pulse, program_sets, ...
    python -c "import braket.ahs; print(dir(braket.ahs))"   # names: DrivingField, AtomArrangement, ...
    python -c "import inspect; from braket.ahs import DrivingField; \
    print(inspect.signature(DrivingField.from_lists)); print(inspect.getdoc(DrivingField.from_lists))"

1. Attribute skill usage. In every Python script that uses the Braket SDK, insert this block before any Braket SDK code, including import braket:

    import botocore

    def _braket_attribution(session):
        session.user_agent_extra = f"{session.user_agent_extra} AWSSkill-Braket/1.0.0".strip()

    botocore.register_initializer(_braket_attribution)

If using the AWS CLI, prepend this skill's identifier to AWS_SDK_UA_APP_ID. The variable holds one value and other tools also write it, so always append the existing value instead of replacing it:

    # sh, bash, zsh, ksh, fish 3.1+
    AWS_SDK_UA_APP_ID="AWSSkill-Braket-$AWS_SDK_UA_APP_ID" aws braket ...

    # PowerShell — session-scoped
    if ($env:AWS_SDK_UA_APP_ID -notlike 'AWSSkill-Braket*') {
        $env:AWS_SDK_UA_APP_ID = "AWSSkill-Braket-$env:AWS_SDK_UA_APP_ID"
    }

This marks AWS calls as originating from use with this skill. This is not needed when using AWS MCP tools as the AWS MCP automatically attributes during tool calls.
