One install command wires 8 CLI coding agents to a shared stealth Chromium

#cli #opensource #ai

I use a bunch of CLI coding agents — Claude Code, Codex CLI, pi, opencode, Gemini CLI, Kiro, Amp, Crush — and every one of them shipped its own headless Chromium that gets blocked by basic bot checks (navigator.webdriver, missing plugins, the usual headless fingerprints).

The fix itself isn't novel. Patched stealth Chromium has existed for years. The annoying part is wiring it into each agent — every one wants its config in a different file:

Claude Code → CLAUDE.md
Codex CLI / opencode → AGENTS.md
Gemini CLI → GEMINI.md
Kiro → .kiro/steering/
Amp / Crush → their own dotfiles

…and all of them need to point at the same browser binary.

So I spent a weekend writing a one-command installer that does the wiring:

git clone https://github.com/Blue-B/browser-harness-kit
cd browser-harness-kit
bash install.sh

It detects which of the 8 agents you have installed, writes the right rule file for each, and creates a shared ~/.playwright/cli.config.json so they all hit the same stealth Chromium through pi-playwright as the CLI runner.

Result

Every agent drives a real headed Chromium that passes:

navigator.webdriver check
plugin / mimeType length checks
window.chrome shape
full bot.sannysoft.com matrix

Screenshot of the pass matrix and verify output are in the README.

What it isn't

This repo is integration glue only. It does NOT bundle or redistribute:

[CloakBrowser]https://www.reddit.com/r/SideProject/comments/1tgrmo3(https://github.com/CloakHQ/CloakBrowser) — the actual stealth Chromium build (linked, not bundled)
Playwright + pi-playwright — the runner
The 8 agents themselves — each lives at its own home

Just the wiring between them, so I don't have to redo it on every fresh box.
