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

invoice-chase 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 8d 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.

Invoice Chase — Debt Chaser

"Chase late invoices."

Unpaid invoices are interest-free loans you never agreed to make. This skill gets the money in while keeping the client.

When to use

  • "Three clients haven't paid since March — get the money in."
  • "This invoice is 45 days overdue, what do I send?" — any single stubborn invoice.
  • "Here's my invoice export / AR aging — who do I chase first?"
  • Receivables creeping past 30 days while the owner "doesn't want to be annoying."
  • Standing up a weekly collections routine so lateness stops compounding.

Workflow

  1. Build the aging ladder. From pasted data or CSV (client, invoice #, amount, issue date, due date, last contact), compute days overdue with code and bucket: current, 1–30, 31–60, 61–90, 90+.
  2. Prioritize. Rank by amount × age. Most of the money usually sits in three invoices — name them as this week's targets.
  3. Assign each invoice a rung based on days overdue and chase history. Never skip a rung the client hasn't actually received; pressure without a paper trail reads as hostility.
  4. Draft the emails from the templates below, personalized: their name, the exact amount, the real due date, and one specific detail proving a human wrote it.
  5. Apply the tone rules.
    • Assume incompetence before malice — rung 1 always presumes an oversight.
    • Escalate consequences, never insults. The facts get harder; the manners don't change.
    • The money and the relationship are separate threads: chase firmly, stay warm.
    • Every message offers one easy exit: confirm a date, pay a part, or flag a dispute.
  6. Open the chase log. Every action and response gets a row — it is both memory and, if things ever go legal, evidence.
  7. Set the cadence. Rungs 7 days apart from the first overdue day; phone at 60+ days or after a silent final notice. Diarize the next action before closing the session.
  8. Know when to fold. Recommend write-off when chasing costs more than the balance: client dark after final notice plus a call, a dispute with no resolution path, or an amount worth less than the hours to collect it. Pair every write-off with stop-work and prepayment terms going forward.
