- I'm including this because it creates a highly-visible surface by which the CWD can be exposed.
- Furthermore: Right-click on a region of output -> "Copy all command output"
- Right-click -> "Rerun this command"

#### VsCode impl

* This is where VsCode actually injects the args:
* https://github.com/microsoft/vscode/blob/3a28d8d2e1044f2fe28f93076df911fd8fc9fd98/src/vs/platform/terminal/node/terminalEnvironment.ts#L114-L149
* looks like it's mostly:
* Is this commandline something we know how to inject our script into? If so, then inject the CLI args and environment vars
* https://github.com/microsoft/vscode/blob/ef6f1349eb824cef6635d9a3083b871a1c5ddbdf/src/vs/platform/terminal/common/xterm/shellIntegrationAddon.ts#
* https://github.com/microsoft/vscode/blob/ef6f1349eb824cef6635d9a3083b871a1c5ddbdf/src/vs/workbench/contrib/terminal/common/scripts/shellIntegration.ps1#

The issue is a broad checklist linking terminal issues and VS Code references, including terminalEnvironment.ts, shellIntegrationAddon.ts, and shellIntegration.ps1. Start by reviewing those references and the linked checklist items to identify a narrowly scoped component. Done is not defined for the overall issue; the scope would need to be narrowed before implementation.
