> ## Agent Instructions
> Prefer the qBraid CLI for programmatic platform actions: pip install 'qbraid-cli>=0.12', then run `qbraid configure` once with an API key from https://account.qbraid.com/account/api-keys.
> Always install the latest packages (pip install -U qbraid qbraid-cli); do not pin versions from memory. qbraid-cli below 0.12.0 is incompatible with the current API.
> Device IDs use the QRN format vendor:provider:type:name (e.g. qbraid:qbraid:sim:qir-sv, rigetti:rigetti:qpu:cepheus-1-108q). Legacy underscore IDs are deprecated.
> The REST API base URL is https://api-v2.qbraid.com/api/v1, authenticated with an X-API-Key header.
> Free simulators cost no credits; QPU and GPU jobs consume credits. Surface the estimated cost to the user before submitting a paid job.
> For account signup, API keys, credits, and end-to-end action recipes, see https://qbraid.com/llms.txt.

# Usage Guidelines

> Instructions to help you navigate, manage, and customize your lab environment effectively.

## Customizing Your Environment

Your `.bashrc` file contains a specific delimiter to delineate which sections of the file can be safely modified to persist between sessions. Here is the structure of the delimiter:

```bash theme={"dark"}
# ==================== DO NOT MODIFY CODE ABOVE THIS LINE ====================
# ANY CHANGES ABOVE THIS LINE WILL BE OVERWRITTEN DURING QBRAID SYSTEM STARTUP.
# You may add your custom configurations below this line.
```

Please ensure that **any customizations** you wish to retain are added **below** this delimiter line. Changes made above this line will not be saved when your session ends.

## Suppressing the Terminal Banner

If you prefer not to see the qBraid terminal banner during startup, you can suppress it by setting the `QBRAID_SHOW_BANNER` environment variable to `false`. This adjustment can be made by executing the following command in terminal:

```bash theme={"dark"}
echo "export QBRAID_SHOW_BANNER=false" >> "$HOME/.bashrc"
```

This command appends the setting to disable the banner to the end of your `.bashrc` file, ensuring it takes effect in all future terminal sessions.
