Orchestration

Orca Orchestration

This discovery stub loads the version-matched guide from the Orca executable used for this session.

Never substitute a non-Orca subagent tool when the user asked for Orca orchestration.

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

ORCA skills get orchestration

That prints the compact, version-matched guide for the exact binary that will handle your next commands. It covers the normal local coordinator loop and dispatched-worker obligations. For a conditional action gate such as remote placement, uncertain release recovery, or expanded DAG work, load only the reference that gate names with ORCA skills get orchestration --reference references/.md (--references lists the names). If that binary rejects --reference, run ORCA skills get orchestration --full and read the named bundled reference before acting.

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 it fails with runtime_access_denied, your sandbox blocked the connection: re-run it with escalated permissions, and do not run ORCA open or restart Orca. If skills get is unknown, explain that updating Orca restores the guide; use --help for read-only discovery and do not guess unsupported commands.
