Extensions inject not applicable environment variables into local integrated terminal

[floriangosse]

Does this issue occur when all extensions are disabled?: No – as it's a general problem with extensions.

• VS Code Version: 1.100.2
• OS Version: macOS 15.4.1

Steps to Reproduce:

1. Run a project inside a dev container with Python and/or GitHub Copilot extension (many other extensions will probably work as well)
2. From inside the dev container open an integrated local terminal
3. Inspect the environment variables (env or via "Show Environment Contributions")

The extensions inject environment variables that reference paths or irrelevant at all in the local shell.

Trimmed output of "Show Environment Contributions":

# Terminal Environment Changes

## Extension: vscode.git

Enables the following features: git auth provider

- `GIT_ASKPASS=/vscode/vscode-server/bin/linux-arm64/848b80aeb52026648a8ff9f7c45a9b0a80641e2e/extensions/git/dist/askpass.sh`
- `VSCODE_GIT_ASKPASS_NODE=/vscode/vscode-server/bin/linux-arm64/848b80aeb52026648a8ff9f7c45a9b0a80641e2e/node`
- `VSCODE_GIT_ASKPASS_EXTRA_ARGS=`
- `VSCODE_GIT_ASKPASS_MAIN=/vscode/vscode-server/bin/linux-arm64/848b80aeb52026648a8ff9f7c45a9b0a80641e2e/extensions/git/dist/askpass-main.js`
- `VSCODE_GIT_IPC_HANDLE=/tmp/vscode-git-7fe25dbcc7.sock`

## Extension: GitHub.copilot-chat

Enables use of the `copilot-debug` command in the terminal.

- `PATH=${env:PATH}:/home/user/.vscode-server/data/User/globalStorage/github.copilot-chat/debugCommand`

## Extension: ms-python.debugpy

Enables use of [no-config debugging](https://github.com/microsoft/vscode-python-debugger/wiki/No%E2%80%90Config-Debugging), `debugpy <script.py>`, in the terminal.

- `PYDEVD_DISABLE_FILE_VALIDATION=1`
- `VSCODE_DEBUGPY_ADAPTER_ENDPOINTS=/home/user/.vscode-server/extensions/ms-python.debugpy-2025.8.0-linux-arm64/.noConfigDebugAdapterEndpoints/endpoint-3004ce93f7e4ecfc.txt`
- `PATH=${env:PATH}:/home/user/.vscode-server/extensions/ms-python.debugpy-2025.8.0-linux-arm64/bundled/scripts/noConfigScripts`
- `BUNDLED_DEBUGPY_PATH=/home/user/.vscode-server/extensions/ms-python.debugpy-2025.8.0-linux-arm64/bundled/libs/debugpy`

## Extension: ms-python.python

Activated environment for `/var/env/bin/python`

- `PATH=/var/env/bin:${env:PATH}`
- `PS1=(env) ${env:PS1}`

All these extensions injected environment variables that aren't relevant or even available on my host/local system?
