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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00021 | $0.01164 |
| Opus 5 | $0.00010 | $0.00582 |
| Sonnet 5 | $0.00004 | $0.00233 |
| Haiku 4.5 | $0.00002 | $0.00116 |
Grade A, and why
vercel-dns 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 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.
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 I Do
Manage DNS records for domains hosted on Vercel, including:
- List existing DNS records
- Add new DNS records (A, AAAA, CNAME, TXT, MX, etc.)
- Remove DNS records
- Switch between Vercel teams/accounts
Prerequisites
- Vercel CLI installed:
npm i -g vercelorbrew install vercel-cli - Logged in:
vercel login - Domain must be on Vercel nameservers or have Vercel as DNS provider
0 Finance Project
For the 0 Finance project, always use --scope prologe:
vercel dns ls 0.finance --scope prologe
vercel logs www.0.finance --scope prologe
Common Commands
Check Login & Team
# Check who you're logged in as
vercel whoami
# List available teams
vercel teams ls
# Switch to a specific team (use slug, not display name)
vercel switch <team-slug>
# Or use --scope flag instead of switching
vercel domains ls --scope prologe
List Domains & Records
# List all domains in current team/account
vercel domains ls --scope prologe
# List DNS records for a specific domain
vercel dns ls <domain> --scope prologe
Add DNS Records
# Add A record
vercel dns add <domain> <subdomain> A <ip-address>
# Add CNAME record
vercel dns add <domain> <subdomain> CNAME <target>
# Add TXT record (use quotes for values with special chars)
vercel dns add <domain> <subdomain> TXT '<value>'
# Add MX record with priority
# NOTE: MX priority is a separate argument (not embedded in the value)
vercel dns add <domain> <subdomain> MX <mail-server> <priority>
# Add record at apex (root domain) - use empty string or @
vercel dns add <domain> '' TXT '<value>'
vercel dns add <domain> @ MX mail.example.com 10
Remove DNS Records
# First list to get record ID
vercel dns ls <domain>
# Remove by record ID
vercel dns rm <record-id>
# Remove with confirmation skip
vercel dns rm <record-id> --yes
Examples
Add Email DNS Records (MX + SPF)
# Add MX record for receiving email
# WARNING: Setting MX at the apex (root) will route *all* inbound mail for the domain.
# If the domain already uses Google Workspace / Fastmail / etc, prefer a dedicated subdomain.
vercel dns add example.com '' MX inbound-smtp.us-east-1.amazonaws.com 10
# Safer: use a subdomain for inbound routing
vercel dns add example.com inbound MX inbound-smtp.us-east-1.amazonaws.com 10
# Add SPF record
vercel dns add example.com '' TXT 'v=spf1 include:amazonses.com ~all'
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.

vercel-dns is a skill published in the GitHub repository different-ai/agent-bank (249 stars, last pushed 5mo ago), licensed MIT. It adds 21 tokens to every session and 1,164 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
