@cotal-ai/orca

The Orca integration: a thin driver over the public orca CLI plus a self-registering orca Runtime provider. Importing it registers the runtime with the core Registry, so the manager can spawn agents into native Orca terminals.

Tier: extensions/. Depends on @cotal-ai/core; self-registers on import.

What it does

• Resolves the launch cwd to the enclosing Orca worktree with orca worktree current --json, then targets that stable worktree id for terminal creation.
• Runs the agent from the exact launch cwd, even though Orca terminals are attached to the worktree.
• Keeps Cotal launch env and credentials out of the Orca command line by writing a private Node launcher script, passing only exec '<node>' '<script>' to Orca, and deleting the launcher after it loads.
• Forces Orca CLI lifecycle calls to the local runtime by removing ambient remote-runtime selectors.
• Uses Orca terminal handles for status, interrupt, and close. Watching is native: switch to the Orca tab rather than cotal attach.
• Waits for exit through Orca's bounded native terminal wait --for exit, following handle rotation by stable PTY id and failing closed on timeout or an unreachable runtime.
• Contributes a Runtime only, not a TerminalLayout provider for setup layouts.

Orca must open terminals with a POSIX-compatible shell that supports exec and single-quoted arguments. Driver calls are synchronous because Cotal's Runtime lifecycle contract is synchronous; short probe caches batch status checks and repeated launches from the same cwd. Every read-only call (status, worktree and terminal lookups, screen reads) gives up after 2 seconds, so an Orca app that stops answering cannot block the manager. A status check that gives up reports the agent as still running.

Usage

Install it into the published CLI:

cotal ext add @cotal-ai/orca
cotal supervise --runtime orca

Library composition roots can still import it explicitly:

import "@cotal-ai/orca"; // self-registers

The runtime can also be selected with runtime: orca in a mesh manifest.

Testing

pnpm smoke:orca:live exercises the driver and runtime directly. pnpm smoke:orca-e2e:live runs the complete operator journey against live Orca and Claude Code: install this package with cotal ext, launch a runtime: orca manifest, observe the agent through cotal ps, then shut down and remove the extension.
