Run Kiro in Agentastic
AWS's spec-driven coding CLI, with trusted-tool execution and chat-session resume.
What Agentastic adds
Give every task its own worktree, branch, or container.
Keep Kiro's real CLI and your existing configuration.
Inspect the diff, run code review, test, and open a pull request.
Launch Kiro
- 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 Kiro, 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 Kiro supports
- Launch from a task description: supported
Type the task in Agent Home and Agentastic hands it to kiro-cli chat at launch, so the run starts from your prompt instead of an empty session.
- Unattended runs: supported
Kiro 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 Kiro rather than emulating it, so runs begin with edits.
- Resume a session: supported
Reopen the last Kiro session for a worktree and keep its history — useful when reviewing the diff turns up one more change.
- Structured chat: supported
Talk to Kiro in a native chat that renders thinking, nested tool calls, plans, and permission requests as structured events instead of scraped terminal output.
- Code review: not supported
Kiro writes the change; pair it with a review-capable agent for the pass before merge.
Agentastic reads these from Kiro'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.
Kiro questions
Why run Kiro in Agentastic instead of the Kiro IDE?
Run it in Agentastic when you want Kiro working beside other agents, such as Claude Code or Codex, on the same repository. Agentastic launches kiro-cli chat with the sign-in you already have and gives it a git worktree, terminal, diff view, and code review for each task, plus a structured chat view of the session.
How do I run multiple Kiro sessions in parallel?
Start each task from Agent Home in worktree mode. Agentastic gives every run its own git worktree and terminal, so several Kiro sessions can work in one repository without editing the same files.
How do I install Kiro?
Run curl -fsSL https://cli.kiro.dev/install | bash, then sign in the way Kiro's documentation describes. Agentastic finds the kiro-cli chat command on your PATH when you open a repository.
Does Agentastic charge for Kiro?
No. Agentastic is free and does not proxy model calls. It launches Kiro with the credentials and plan you already use, so any usage is billed by your provider, not by Agentastic.
