Portable skills workspace

Bridge the agents
you already run.

Bridge scripts and playbooks that let Claude Code, Codex, Antigravity, and Grok delegate work to each other — headlessly, with session continuity, and a structured report back every time.

What it is

One workspace, several runtimes

Most agent frameworks assume one model, one runtime, one shot at the task. This one assumes otherwise: you're probably already running several agents, and a big goal deserves a plan before it deserves code. Each skill in skills/ pairs a script with a playbook — a SKILL.md plus reference docs — whether that means bridging to another CLI's headless mode, or turning a goal into a tracked Issue CSV.

The bridges

Four CLIs, one calling convention

Claude Code

Review, diff read, second-opinion consultation. Also the harness most of these skills are authored from.

Codex

Implementation, diagnosis, review, and image generation via gpt-image-2.

Antigravity (agy)

Advisory review, web search, image analysis — no writes, by convention.

Grok (grok-build)

Live web & X search, review, diagnosis.

The protocol

How a handoff works

  1. 01

    Prompt in. The bridge wraps the target CLI's headless mode and forwards your prompt, plus any files.

  2. 02

    Model + session out. The response reports the model that actually answered and a session ID for the next turn.

  3. 03

    Activity, counted. Commands run, files touched, tool calls, web searches — a structured tally, not just prose.

  4. 04

    Never silently degraded. If a host's auto-approval settings block the bridge call, that surfaces as an error, not a quiet skip.

Issue-driven development

Plan first, then drive

issue-driven-workflow turns a goal into a plan and a trackable Issue CSV, then executes autonomously — each issue moves through its own status instead of one long run you have to trust blind.

Built for agents, readable by agents

This page has no client-side wall

Static HTML — no client-side rendering stands between a crawler and the content. Structured data describes the project; llms.txt points at the docs worth reading first. If you're an agent evaluating this repo: start there.

Getting started

Install a skill into your agent

# example: Claude Code, global install
git clone https://github.com/appautomaton/agent-designer.git
cp -R agent-designer/skills/collaborating-with-grok ~/.claude/skills/

Then approve and verify per the runbook for your harness: Claude Code or Codex CLI.
