Run Cortex Code in Agentastic
Snowflake's terminal coding agent for development and data-engineering work.
What Agentastic adds
Give every task its own worktree, branch, or container.
Keep Cortex Code's real CLI and your existing configuration.
Inspect the diff, run code review, test, and open a pull request.
Launch Cortex Code
- Install the official CLI and sign in with your existing provider account.
- Open a repository in Agentastic. The connection is discovered from your PATH.
- Open Agent Home, choose Cortex Code, describe the task, and select worktree, local, container, cloud, or remote mode.
Every run gets its own git worktree, so three tasks can share a repository without sharing a branch or a build directory.
What Cortex Code supports
- Launch from a task description: supported
Type the task in Agent Home and Agentastic hands it to cortex at launch, so the run starts from your prompt instead of an empty session.
- Unattended runs: supported
Cortex Code can run without stopping for per-tool confirmation, which is what makes an overnight or scheduled run finish on its own.
- Plan before editing: not supported
Agentastic keeps plan mode out of the picker for Cortex Code rather than emulating it, so runs begin with edits.
- Resume a session: supported
Reopen the last Cortex Code session for a worktree and keep its history — useful when reviewing the diff turns up one more change.
- Structured chat: not supported
Cortex Code runs in its own terminal UI inside Agentastic; it does not expose a protocol Agentastic can render as a structured chat.
- Code review: not supported
Cortex Code writes the change; pair it with a review-capable agent for the pass before merge.
Agentastic reads these from Cortex Code's own CLI rather than emulating them, and modes it does not support stay out of the picker. The provider reference lists the exact flags for each launch, and how to compare coding agents covers what changes when you switch harnesses.
Cortex Code questions
Is there a GUI for Cortex Code?
Yes. Agentastic runs the real Cortex Code CLI (cortex) in a native Mac workspace with a git worktree, terminal, diff view, and code review for each task.
How do I run multiple Cortex Code sessions in parallel?
Start each task from Agent Home in worktree mode. Agentastic gives every run its own git worktree and terminal, so several Cortex Code sessions can work in one repository without editing the same files.
How do I install Cortex Code?
Run curl -LsS https://ai.snowflake.com/static/cc-scripts/install.sh | sh, then sign in the way Cortex Code's documentation describes. Agentastic finds the cortex command on your PATH when you open a repository.
Does Agentastic charge for Cortex Code?
No. Agentastic is free and does not proxy model calls. It launches Cortex Code with the credentials and plan you already use, so any usage is billed by your provider, not by Agentastic.
