Run Letta Code in Agentastic
A memory-first coding agent that Agentastic starts as a fresh TUI conversation, with automatic prompt delivery.
What Agentastic adds
Give every task its own worktree, branch, or container.
Keep Letta Code's real CLI and your existing configuration.
Inspect the diff, run code review, test, and open a pull request.
Launch Letta 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 Letta 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 Letta Code supports
- Launch from a task description: supported
Type the task in Agent Home and Agentastic hands it to letta at launch, so the run starts from your prompt instead of an empty session.
- Unattended runs: supported
Letta 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 Letta Code rather than emulating it, so runs begin with edits.
- Resume a session: not supported
Every launch of Letta Code is a fresh session; carry context forward in the repository rather than in the agent.
- Structured chat: not supported
Letta 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
Letta Code writes the change; pair it with a review-capable agent for the pass before merge.
Agentastic reads these from Letta 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.
Letta Code questions
Is there a GUI for Letta Code?
Yes. Agentastic runs the real Letta Code CLI (letta) in a native Mac workspace with a git worktree, terminal, diff view, and code review for each task.
How do I run multiple Letta 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 Letta Code sessions can work in one repository without editing the same files.
How do I install Letta Code?
Run npm install -g @letta-ai/letta-code, then sign in the way Letta Code's documentation describes. Agentastic finds the letta command on your PATH when you open a repository.
Does Agentastic charge for Letta Code?
No. Agentastic is free and does not proxy model calls. It launches Letta Code with the credentials and plan you already use, so any usage is billed by your provider, not by Agentastic.
