In plain words
What is it for?
Use it after deploying a multi-region service to test signup in each listed region and confirm the expected demo answer.
Why use it?
It helps detect signup and region-routing problems that may appear only after a multi-region deployment.

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 D, and why

verify-prod-signup scanned grade D with 3 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 9d 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.

Sends data to an external URLmediumData exfiltration

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

await fetch('https://app.useatlas.dev/api/login/resolve-region', { method: 'POST', headers: { 'content-type': 'application/json' },

Reaches for credential fileshighPrivilege escalation

SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.

railway ssh keys add -n atlas-teardown # auto-detects ~/.ssh/id_ed25519*, registers via CLI

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

curl -s https://api.useatlas.dev/api/v1/auth/region-probe -H 'content-type: application/json' -d "{\"emailHash\":\"$H\"}" # → {"exists":false}

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.
