What is email-review?

A skill that checks cold-email sequences for writing quality, important copy rules, compliance, and client preferences. It scores the emails and can produce a final reviewed version when the quality score is high enough.

Use it after writing cold-email copy and before finalizing the sequence. It helps evaluate emails, suggest revisions, and prepare the reviewed email file.

It provides a structured review before an email sequence is used. It helps catch copy problems, rule violations, and mismatches with the client’s preferences.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00061	$0.04409
Opus 5.5	$0.00024	$0.01764
Sonnet 5.5	$0.00012	$0.00882
Haiku 4.5	$0.00006	$0.00441

Security

Grade A, and why

email-review 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 9d 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.

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.

Email Review Skill

Review a segment's emails.md against the lint contract, the critical copy rules, the QA checklists and client preferences. Score it 1-5. Pass = score >= 4.5 and zero HARD/REJECT violations. On pass, write the fixed copy to emails_v2.md in the segment folder. On fail, write nothing and hand revision instructions back to email-copywriting. When you review your own fresh draft (self-review before handing copy back), apply the same checklist and fix every violation before returning the copy.

Loop with email-copywriting until the copy passes, at most 3 rounds; after the third failed round, show the last review and let the user decide (accept the open issues, or change the strategy). You only read and write files: sending and launch happen in the user's own tools.

Inputs

Segment folder: ./cold-email/{slug}/{n} - {segment-slug}/ (0 - default/ for the Default segment). Ask when the user has more than one.
The copy: the segment's emails.md from email-copywriting, or a draft the user pastes.
The offer and ICP to check claims against: research.md in the campaign folder, notes.md when it exists, and the company files from knowledge-setup when the user keeps them, plus any research the user provides.
Strategy and ICP Voice Card: the segment's strategy.md, and the Voice Card in the ## Notes section of emails.md. Priority order is under Priority and scope.
The segment's AI variables: the ### headings of the segment's prompts.md when prompt-writer has run; otherwise the AI variable list in strategy.md.

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.
