In plain words
What is it for?
Use it to review or write cold-email copy, check subject lines and messages for banned words, and apply feedback from deliverability reviews.

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

spam-word-checker 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 13d 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.

Spam Word Checker

Always-on spam and deliverability rules. Apply to every subject line, opener, second line, follow-up, and CTA generated or reviewed.


When These Rules Apply

  • Subject lines, openers, second lines, follow-ups, CTAs
  • Any cold outreach copy being written or QA'd
  • If a deliverability checker or review flags a word/phrase, treat it as banned going forward unless user explicitly approves an exception
  • When in doubt, choose the lower-hype rewrite

Banned Single Words

Do not use any of the following standalone or as part of a compound word/phrase:

get, bank, credit, access, open, compare, problem, now, billing, deal, finance, financial, claims, insurance, mortgage, soon, new, performance, freedom, home, sales, medical, urgent, life, marketing, investment, diagnostics, friend, cash, invoice, extra, purchase

Nuance: Punctuation, hyphens, or splits do not make a banned token safe. Treat close variants as banned when the root token is still obvious:

  • cash-cycle → still cash → banned
  • invoice-line → still invoice → banned
  • extra-room → still extra → banned
  • purchase-cycle → still purchase → banned

Banned Short Phrases

off chance, one time, all good, following up here, last note from me here, great fit, bumping this once, just following up once, circle back, one more quick follow-up, keep this open, compare notes, compare notes live, appreciate the reply

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.
