Orca is an application for running and coordinating multiple coding agents, giving each agent an isolated Git worktree while tracking their work in one place. Developers use it to run agents such as Codex, ClaudeCode, OpenCode, or Pi in parallel across desktop, mobile, local terminals, or remote servers.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00118 | $0.00835 |
| Opus 5.5 | $0.00047 | $0.00334 |
| Sonnet 5.5 | $0.00024 | $0.00167 |
| Haiku 4.5 | $0.00012 | $0.00084 |
Grade A, and why
orchestration scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 27d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Orca Orchestration
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.
Resolve the CLI for this session
Choose the executable once and reuse it for every later command:
- If the
ORCA_CLI_COMMANDenvironment 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, useorca-dev. - Otherwise, on Linux outside an Orca-managed terminal, use
orca-ide. Never run bareorcathere — 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.

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

orchestration is a skill published in the GitHub repository stablyai/orca (99,715 stars, last pushed today), licensed MIT. It adds 118 tokens to every session and 835 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
