gum-login

gum-login is a command for Claude Code from ehmo/gum. It costs 0 tokens per session (325 once invoked), scanned A, original, MIT.

A command that signs the gum command-line tool into Google services using OAuth, which is a standard permission-based login system. It can open a browser or print a login link for headless machines such as SSH sessions and devcontainers.

In plain words
What is it for?
Logging in, choosing service permissions, using separate profiles, and authorizing gum on machines without a graphical browser.
Why use it?
It handles the authorization step needed before gum can access connected services. You can request only the permissions or services required for a task.

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-login 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 6d 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.

Usage

gum login [flags]

Parent

Flags

Flag Type Default Help
--all bool false Request the full catalog scope union (every service). Default is the core Workspace set; the full union needs all those APIs enabled on your OAuth client.
--no-browser bool false Print the URL but don't launch a browser (use for SSH/devcontainer/headless)
--scope stringSlice [] Exact OAuth scope(s) to request; repeat or comma-separate. Overrides --service/--all.
--service stringSlice [] Request only these services' scopes (e.g. --service people,youtube). Comma-separate or repeat.
--log-format string json Log format: json|text
--log-level string info Log level: debug|info|warn|error (overrides GUM_LOG_LEVEL)
--profile string default Profile name to read/write config under

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.
