Setup guide and availability
The Bridge and plugins are not distributed yet. Below is the planned connection design and event map.
Codex
The planned plugin bundles the Bridge and hook configuration for the CLI, IDE extension, and Codex app.
- Wait for the Bridge and plugin release
- After release, add hooks, then review and trust them in /hooks
- Switch the habitat to LIVE on the first event
Project hooks are loaded only for trusted repositories.

What is Agent Simulator?
Agent Simulator is a free browser-based demo that turns sample lifecycle events from coding assistants into five visual work states: idle, thinking, working, needs input, and reviewing. It helps developers understand a shared status model before connecting any live tool.
- Best for
- Developers exploring visual status and supervision patterns for coding assistants.
- Represented tools
- Codex, Claude Code, Google Antigravity, and VS Code sample event mappings.
- Demo boundary
- Generated sample data only; no prompts, files, or tool sessions are read.
How to try the simulator
The interactive demo takes about 30 seconds and requires no account or installation.
- Choose a coding assistant
Select Codex, Claude Code, Google Antigravity, or VS Code to see its sample event names.
- Run a sample event
Send one generated event from the browser preview.
- Read the shared state
See the event map to idle, thinking, working, needs input, or reviewing and move through the habitat.
Agent Simulator FAQ
Is Agent Simulator connected to my coding tool?
No. The current version is a browser-only simulation. It does not connect to Codex, Claude Code, Google Antigravity, or VS Code and does not read their sessions.
Which coding assistants are represented?
The demo includes sample event mappings for Codex, Claude Code, Google Antigravity, and VS Code. Each tool's event names are normalized into the same five visual states.
What data does the demo read or send?
The demo uses generated sample events inside the browser. It does not read prompts, source files, credentials, or tool-session content, and it requires no account.
What do the five states mean?
Idle means ready for a request; thinking means organizing context; working means using tools; needs input means waiting for approval or information; reviewing means checking the result.
