gum-plugin-setup

A command that asks for a plugin’s missing login details, saves them in the operating system’s secure keychain, and tests the plugin.

In plain words
What is it for?
Use it to configure a plugin, verify its credentials, and mark it active when the test succeeds.
Why use it?
It avoids manually finding and storing each required credential, while checking whether the setup works.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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-plugin-setup 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 2d 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

gum plugin setup

Generated from gum schema --json. Do not edit this page by hand; run make docs-commands.

Reads the plugin's credential_descriptors from its manifest, prompts for each missing credential by display_name and setup_hint, stores secrets in the OS keychain, then runs 'gum canary --plugin= --live' to verify the plugin is functional.

On canary success the plugin state is set to 'active'. On canary failure the plugin is quarantined with CANARY_FAILED; run 'gum plugin reload ' after correcting credentials.

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.
