gum-auth

gum-auth is a command for coding agents from ehmo/gum. It costs 0 tokens per session (388 once invoked), scanned A, original, MIT.

Command reference for managing Google OAuth credentials in the gum command-line tool. OAuth is a sign-in method that lets an application obtain permission to use an account or service.

In plain words
What is it for?
Use it to log in, check configured permissions, prepare credentials for an operation, and configure API keys, OAuth clients, service accounts, or Google Ads tokens.
Why use it?
It explains the available login, setup, status, and credential-provider commands without requiring developers to inspect the command's schema.

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

gum-auth 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 4d 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 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.
