8686`DO_NOT_TRACK`, set to any value other than `0` or `false`, turns usage analytics and error reports off. It is the same switch as `disable_telemetry = true` in the configuration file. `GITHUB_TOKEN` (or `GH_TOKEN`) is optional and is used only against `api.github.com`, to lift the rate limit when you install a skill from a GitHub repository. Claude Science also reads the standard proxy variables (`HTTPS_PROXY`, `HTTP_PROXY`, `NO_PROXY`, and `ALL_PROXY`); see [Use Claude Science on a corporate network](/docs/claude-science/corporate-networks#connect-through-an-outbound-proxy). The proxy address variables are the one case where the environment overrides the configuration file, and `NO_PROXY` is merged with the `no_proxy` key rather than replacing it. Every other setting belongs in the configuration file.

88An app started from the macOS Dock or Finder, or from the Windows Start menu, does not see variables exported in a terminal. The macOS app reads the `env` file in the data directory (by default `~/.claude-science/env`) when it starts, so put the variable there as a `KEY=VALUE` line, then quit and reopen the app. On Windows, set it as a user environment variable, then quit and reopen the app. See [How the environment variables reach the app](/docs/claude-science/corporate-networks#how-the-environment-variables-reach-the-app).

90* **macOS**: the app reads the `env` file in the data directory (by default `~/.claude-science/env`) when it starts. It applies only a fixed list of variables from the file, which includes `DO_NOT_TRACK` and the proxy variables but not `GITHUB_TOKEN` or `GH_TOKEN`. Put `DO_NOT_TRACK` or a proxy variable there as a `KEY=VALUE` line, then quit and reopen the app. Add a GitHub token under **Settings > Credentials** instead, and delete its line from the file. Before version 0.1.56, the file could set any variable.
91* **Windows**: set the variable as a user environment variable, then quit and reopen the app.
