Agents

Nine coding agents. One window.

Halterio runs the agent CLIs you already have, signed in to your own plans, side by side and each on its own branch. Here is what it runs, and what it adds to every one of them.

Claude Code

Anthropic

Anthropic’s agent in the terminal, run by Halterio directly. Pick the model and the effort per session, keep more than one account, watch each plan’s usage, and resume after a limit resets.

Command: claude
Driven: Natively
Accounts: Several, with usage meters

curl -fsSL https://claude.ai/install.sh | bash

Codex

OpenAI

OpenAI’s coding agent, run by Halterio directly. Model picker, several accounts and usage meters; on another computer, a Cloud computer or a WSL distro it signs in with a one-time code.

Command: codex
Driven: Natively
Accounts: Several, with usage meters

npm install -g @openai/codex

Cursor

Cursor’s agent CLI, run by Halterio directly with your Cursor plan. Any session can also be opened in the Cursor editor from the app.

Command: cursor-agent
Driven: Natively
Accounts: Several, with usage meters

curl https://cursor.com/install -fsS | bash

Devin

Cognition

Cognition’s Devin, through its CLI over the Agent Client Protocol (ACP). Sign in once with devin auth login; Halterio does the rest.

Command: devin
Driven: Over ACP
Accounts: Several, with usage meters

curl -fsSL https://cli.devin.ai/install.sh | bash

Grok

xAI

xAI’s Grok Build agent, through its CLI over ACP. Sign in once with grok login.

Command: grok
Driven: Over ACP
Accounts: Several, with usage meters

npm install -g @xai-official/grok

Hermes

Nous Research

Nous Research’s Hermes Agent, over ACP. Hermes keeps its own pool of credentials and rotates through it; Halterio lists them and adds to them with hermes auth add.

Command: hermes
Driven: Over ACP
Accounts: Its own pool

curl -fsSL https://hermes-agent.nousresearch.com/install.sh | bash

Pi

pi.dev

The Pi coding agent, run by Halterio over its own protocol. Pi signs in to the provider you choose, ChatGPT or GitHub Copilot among them, with its own login.

Command: pi
Driven: Natively
Accounts: Per provider

npm install -g --ignore-scripts @earendil-works/pi-coding-agent

opencode

SST

SST’s open-source agent, run by Halterio over the same server protocol its own desktop app speaks. It signs in to the provider you choose with opencode auth login.

Command: opencode
Driven: Natively
Accounts: Per provider

curl -fsSL https://opencode.ai/install | bash

Antigravity

Google

Google’s Antigravity agent, over ACP through Google’s own server. There is nothing to install by hand: Halterio fetches a pinned release and checks it against its checksum. One login, no usage meters.

Command: agy_acp_server
Driven: Over ACP
Accounts: One

Installed by Halterio, in Settings → Agents

What Halterio adds to every one of them.

The CLIs do the coding. Halterio builds the part around them: a place for each one to work, a way to see who needs you, and a way to ship.

In the session

A fresh git worktree, or the folder itself, per session
Model and effort pickers, and the account to use
Steer or interrupt a run; answer questions and permission prompts inline
Diff, files and terminals beside the transcript
Commit with a drafted message, then open the pull request

Across sessions

An inbox sidebar: Needs you, snooze, undo, and ⇧⌘J to the next one
Usage meters per plan, and a resume after a limit resets
A lead agent that starts helpers on any harness through Halterio’s MCP server
Pull requests stay with their session, which settles when they merge
Open any session in Cursor, VS Code, Zed or Terminal

Beyond the desk

Mesh: start and follow agents on your other computers
Direct Link: pair a phone or computer once, end-to-end encrypted, no account
Agents on a Cloud computer keep working while your laptop sleeps
Agents that see: HTML designs, charts, simulators and, if you switch it on, your computer
Automations on a schedule, on git or pull request events, or from Linear

How an agent gets into Halterio.

There’s no configuration file and no API key to paste. Halterio uses the CLI and the login you already have.

Found on your PATH

Settings → Agents lists all nine with the version it found. Anything installed and on your PATH is ready; a missing one has an Install button that runs the vendor’s installer.

Signed in once

Sign in to the CLI the way its maker intends, in its terminal or from Settings → Accounts, and every session can use it. Halterio never copies, swaps or refreshes a login; the agent’s own sign-in stays where it is.

On any computer

The same goes for your other computers, a Cloud computer or a WSL distro: each one has its own agents and its own sign-ins, and the sidebar shows them side by side with the ones on this computer.

Bring the agents you already pay for.
