# Per-Workspace Environments This discovery stub loads the version-matched guide from the Orca executable used for this session. ## Resolve the CLI for this session Choose the executable once and reuse it for every later command: - If the `ORCA_CLI_COMMAND` environment variable is set, use its value. Orca exports this for managed WSL sessions. - Otherwise, in a dev checkout whose session exposes `ORCA_DEV_REPO_ROOT`, use `orca-dev`. - Otherwise, on Linux outside an Orca-managed terminal, use `orca-ide`. Never run bare `orca` there — outside Orca's terminals it normally resolves to the GNOME Orca screen reader (`/usr/bin/orca`) and starts speech on the user's machine. - Otherwise, use `orca`. Below, `ORCA` is a placeholder for the executable you resolved. Substitute it before running anything; do not create a shell variable or run `ORCA` literally. This works the same way in POSIX shells, PowerShell, and cmd.exe. If the selected executable cannot run, report its exact error and stop. Do not fall through to another executable, which could silently target a different Orca build. ## Load the version-matched guide before running Orca commands ```text ORCA skills get orca-per-workspace-env ``` Prefer `--json`. Use the selected executable's `--help` for commands or flags the guide does not cover. If a command reports that Orca is not running, start it with `ORCA open --json` and retry. If `skills get` is unknown, explain that updating Orca restores the guide; use `--h...
