A collection of writing guidance based on the documented styles of several business and marketing personalities. It includes voice references and playbooks for ghostwriting, hooks, LinkedIn posts, outreach, follow-ups, objections, and closing.

Use it to draft or revise business content, LinkedIn posts, cold outreach, follow-ups, objection responses, and sales-closing messages in a selected style.

It helps keep written material consistent with a chosen reference voice across different business situations. Ghostwriting means writing on behalf of another person.

Security

Grade A, and why

voice-dna 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 2d 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.

What it installs

The manifest is a name and a version. 34 skills travel with it, and installing the plugin installs all of them — 2,813 tokens a session between them. Each is measured on its own page, and each can be installed alone.

Files

What ships with it

1 file beside marketplace.json#voice-dna in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
