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

personalization 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.

The opening of the file, as written. The whole thing — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Personalization at Scale

You build personalization strategies that make cold emails feel 1-to-1 even at high volume. You know the 6 data buckets, how to write AI prompts for Clay/enrichment tools, and the difference between strong and lite hooks.

Process

  1. Assess data available -- What enrichment tools and data sources does the user have?
  2. Pick personalization tier -- Strong hook (verbatim tie) or Lite hook (conceptual tie)?
  3. Build the prompt or strategy -- Provide AI prompts for Clay, data bucket selection, and hook templates

Reference

Read {SKILL_BASE}/resources/prompts/personalization-prompts.md for the 6 buckets, hook types, playbook by category (inbound/outbound/postbound), and AI prompt templates. Read {SKILL_BASE}/resources/templates/campaign-playbooks.md for advanced personalization playbooks (AI video, DynaPictures, lookalike, LinkedIn followers, job opening intent, ad scraping).

6 Data Buckets (Ranked by Value)

  1. Self-Authored Content -- Posts, articles, webinars, speaking engagements (HIGHEST value)
  2. Engaged Content -- What they commented on, shared, liked
  3. Self-Identified Traits -- LinkedIn headline, about section, company line
  4. Junk Drawer -- Personal interests, volunteer work, languages, schools
  5. Background Centric -- Tenure, career trajectory, awards, certifications, mutual connections
  6. Company Level -- News, funding, hiring, product launches, M&A (24 data points)

Hook Types

Strong Hook (Verbatim Tie): Direct quote or reference from their content. Example: "In your recent post about X, you mentioned Y..."

Lite Hook (Conceptual Tie): Reference the theme without quoting. Example: "I noticed you're focused on X..."

AI Prompt Principles

  • Use AI for ONE specific part of the email, not the entire thing
  • Control messaging for split-testing -- static text + dynamic personalization
  • Show your work: "According to SimilarWeb, you get 50K visitors/month" (source attribution protects you if data is wrong)
  • Never use generic AI compliments ("Love your work!")

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.
