v1.40: Now Supporting 6 AI Coding Clients¶

Harness CLI just got a lot bigger. Version 1.40 adds two new AI coding client integrations — Antigravity CLI and Crush — and brings superpowers workflow skills to every supported client.

What's New¶

Antigravity CLI Support¶

Antigravity CLI (the successor to Gemini CLI) is now a first-class Harness CLI client. It gets:

Skills — all AIOS skills auto-discovered via .gemini/skills/ (Antigravity's native path)
Native instructions — GEMINI.md with ContextDB, codemap, and browser MCP guidance
Team routing — /team <task> shortcut for multi-agent dispatch
Superpowers — brainstorming, planning, debugging, verification workflows

If you were using Gemini CLI before, Antigravity is a drop-in replacement. Same skill paths, same instruction format.

Crush (charmbracelet) Support¶

Crush is a new terminal-based AI coding client from the charmbracelet team. Harness CLI now supports:

Agent emitters — Crush-specific agent definitions in .crush/agents/
Model flags — --model argument passthrough for model selection
YOLO mode — --yolo for fully unattended execution (no confirmation prompts)
Team capability — full team dispatch support

Crush is ideal for headless/CI environments where you want AI coding without interactive prompts.

Superpowers for Everyone¶

Before v1.40, superpowers workflow skills (brainstorming, planning, debugging, TDD, verification) were only wired for Codex and Claude. Now all 6 clients get superpowers:

Client	Skills	Superpowers	Team	Agents
Claude	✅	✅	✅	✅
Codex	✅	✅	✅	✅
Gemini	✅	✅	✅	❌
Antigravity	✅	✅	✅	❌
OpenCode	✅	✅	✅	✅
Crush	✅	✅	✅	✅

Note: Gemini and Antigravity don't support the agents capability because they don't have a native agent-file convention. This is intentional — routing agent-routing.md to a client that can't honor it would be misleading.

Other Changes¶

XHS-only skills removed — core AIOS skills now work across all clients, not just Xiaohongshu-specific ones
OpenCode team support — OpenCode now gets team/model-router/harness instruction injection
Skill sync — sync-skills.mjs updated to handle all 6 clients

Upgrade¶

# macOS / Linux
curl -fsSL https://github.com/rexleimo/harness-cli/releases/latest/download/aios-install.sh | bash

# Windows PowerShell
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12; irm https://github.com/rexleimo/harness-cli/releases/latest/download/aios-install.ps1 | iex

Or update in-place: aios → Update → Doctor.

What's Next¶

Expanding agent support to Gemini/Antigravity if they add native agent-file conventions
Cross-client agent migration (move agent definitions between clients)
Enhanced model routing per client type
