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

list-quality-scorecard 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 12d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/score-list.ts), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 176 lines — stays where its author put it; the contents beside it link to each section on GitHub.

List Quality Scorecard

A CSV of 5,000 leads is not the same as a good list of 5,000 leads. This skill grades your list across 8 dimensions BEFORE you send, catching preventable waste.

Why this exists

The three campaign failure modes cold email runners hit most:

  1. Bad list — the copy doesn't matter when you're emailing the wrong people
  2. Unverified emails — bounces burn domain reputation
  3. ICP drift — you think you're targeting VPs, but the list is mostly Managers

Each of these is catchable before you send, in 5 minutes, for free.

Inputs

A CSV with at minimum these columns:

  • email — the primary email
  • first_name, last_name
  • job_title OR title
  • company_name OR company
  • company_domain (optional, derived from email if missing)
  • company_industry (optional, used for ICP fit scoring)
  • company_headcount (optional, used for ICP fit scoring)

Output

A markdown scorecard with:

  • Letter grade (A+ to F)
  • 8 dimension scores (each 0-100)
  • Top 5 issues to fix
  • Pre-send checklist

Usage

npx tsx scripts/score-list.ts --list=leads.csv --icp-file=client-profile.yaml --out=scorecard.md

Optional --icp-file lets the scorecard compare your list against your declared ICP filters (from /icp-onboarding).

The 8 dimensions

1. Email verification coverage (critical)

  • What: % of emails validated via MillionVerifier or equivalent
  • Rule: 100% of a cold list must be verified before sending. Unverified emails = bounces = dead domains.
  • Score: 100 if all verified, 0 if <50% verified

2. Duplicate email rate

  • What: % of duplicate emails in the list
  • Rule: <1% acceptable, >5% is a problem
  • Score: 100 at 0%, drops linearly

3. Duplicate domain rate

  • What: max # of leads from any single domain
  • Rule: 1-2 leads per domain ideal. 5+ suggests you're over-indexing on one company.
  • Score: 100 if avg <2 per domain, 60 if avg 2-5, 30 if >5

4. Title relevance

Changes

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.
