Get Started Free →Use Orca orchestration for structured multi-agent coordination: threaded messages, blocking ask/reply flows, task dispatch, worker_done/escalation waits, task DAGs, decision gates, coordinator loops, or decomposing work across agents. Use `orca-cli` instead for full ownership handoffs, including requests phrased as "hand off", "handoff", "handover", "give this to another agent", or "another worktree" when the user did not explicitly ask to supervise, monitor, wait for results, or coordinate a DA

This file is a discovery stub, not the usage guide. The full, version-matched Orca orchestration reference is served by the orca binary itself — kept out of this file on purpose so it can never drift from the binary that will actually run your commands.
Engage Orca orchestration whenever you need structured multi-agent coordination: threaded messages, blocking ask/reply flows, task dispatch, worker_done/escalation waits, task DAGs, decision gates, coordinator loops, or decomposing work across agents. Use the orca-cli skill instead for full ownership handoffs ("hand off", "handoff", "handover", "give this to another agent", "another worktree") when the user did not ask to supervise, monitor, wait for results, or coordinate a DAG — and for ordinary terminal control, shell commands, worktree management, and the built-in browser. Coordination requires real Orca runtime state; never substitute a non-Orca subagent tool.
Choose the executable once and reuse it for every later command:
ORCA_CLI_COMMAND environment variable is set, use its value. Orca exports thisfor managed WSL sessions.
ORCA_DEV_REPO_ROOT, use orca-dev.orca-ide. Never run bareorca 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.
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.
textORCA skills get orchestration
That prints the complete, version-matched guide for the exact binary that will handle your next commands — task creation and dispatch, injected lifecycle preambles, worker_done authority, decision gates, and coordinator loops. Read it first, then run the specific command you need.
Don't guess subcommands or flags from memory or from a cached copy of this stub. They change between Orca releases, and this file deliberately no longer lists them. Confirm the app is up with ORCA status --json (start it with ORCA open --json if needed), and prefer --json for agent-driven calls.
skills getUse this fallback only when the selected binary explicitly reports that skills get is an unknown command. Another failure is not proof of an older binary; report it rather than guessing or changing executables. For a confirmed pre-guide binary, use only this bounded, read-only bootstrap to orient. Do not dead-end and do not invent commands:
textORCA status --json ORCA orchestration task-list --json ORCA terminal list --json
Then tell the user that updating Orca restores the full, version-matched guide via ORCA skills get orchestration. Beyond these commands, ask the user rather than guessing a command surface this older binary may not support.
