Orca Lab Orchestration

This file is a discovery stub, not the usage guide. The full, version-matched Orca Lab
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 Lab 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 Lab runtime
state; never substitute a non-Orca Lab subagent tool.

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 Lab 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 Lab-managed terminal, use orca-ide. Never run bare
  orca there — outside Orca Lab'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 Lab build.

ORCA 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 Lab 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.

If an older Orca Lab does not recognize skills get

Use 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:

ORCA status --json
ORCA orchestration task-list --json
ORCA terminal list --json

Then tell the user that updating Orca Lab 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.
