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.

ModelPer sessionOnce invoked
Fable 5.1 $0.00054 $0.00304
Opus 5.5 $0.00022 $0.00122
Sonnet 5.5 $0.00011 $0.00061
Haiku 4.5 $0.00005 $0.00030

Security

Grade A, and why

email-dunning-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 2mo 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

Email & Dunning Setup

Two Layers

1. Stripe-native (Dashboard)

Settings → Billing → Customer emails:

  • Failed payment
  • Expiring card
  • Trial ending
  • Receipts

Verify toggles ON for production.

2. Custom (your app)

Webhook invoice.payment_failed → send email with Portal link.

Codebase Audit

Grep: payment_failed, payment-failed, invoice.payment_failed, sendPaymentFailed, Resend/SendGrid/Postmark.

MCP + Code Workflow

  1. Confirm webhook handler exists (webhook-reliability)
  2. Sample past_due subs (past-due-dunning) — were emails sent? (logs/DB)
  3. Customer Portal URL in email template?

Output Template

Dunning Email Audit

Stripe emails: [on/off per type]
Custom email on payment_failed: yes/no
Portal link in email: yes/no
Gap: [description]

Recommended sequence:
Day 0 fail → Stripe retry
Day 3 → custom email + portal
Day 7 → final notice

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.
