doctor

doctor is a skill for Claude Code, Codex from stickerdaniel/browserjack. It costs 15 tokens per session (106 once invoked), scanned A, original, MIT.

A diagnostic tool for the local bridge that connects ChatGPT's browser runtime to other software. It checks whether the bridge works without opening or reading browser data.

In plain words
What is it for?
Running a live bridge health check, explaining failures, and identifying when a compatible bridge release is needed.
Why use it?
It helps identify connection or compatibility problems while keeping browser tabs, cookies, history, and login files out of the check.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

doctor scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Run the installed bridge doctor and explain every failure without weakening security checks:

"$HOME/Library/Application Support/browserjack/bin/browserjack" doctor --live

Do not inspect tabs, page content, cookies, browser history, login databases, or OpenAI authentication files. Do not recommend trusting an unknown ChatGPT.app build. If compatibility fails, recommend installing a bridge release that explicitly supports the installed app build.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
