A licensed plugin for Claude

A writing system with teeth.

Lock your project's voice into a config every skill enforces, then draft, refine and repurpose copy against it. Nothing drafts until your rules exist — and the writing gets sharper the more you use it.

The difference

Most tools hand you a style guide and hope you follow it. Copylock enforces yours.

01One config every skill reads — the single source of truth for your voice.
02A hard human copy gate. Nothing ships without you signing it off.
03Checks that block, not advise — the rule stops the draft, it doesn't suggest.
04Clarity over compression, held as a standing rule on every line.
05A loop that learns from your edits and proposes rule changes you approve.
06Your voice is yours. None of ours ships — Copylock asks you for yours.
What's inside

Eight skills. One enforced voice.

Start with voice-setup; it writes the two config files every other skill reads. Add the learning loop and the distribution skills when you need them.

voice-setup Core

Start here. A ten-minute interview builds your voice config — how you want to sound, your hard rules, and a sample you approve. Nothing else runs until it exists.

clear-writing Core

Clarity over compression: name the concrete thing, cut the jargon, spell out the mechanism, read it back as a stranger would.

draft-piece Core

Draft a long-form piece against your config: one idea, one search phrase to rank for, headings that guide the reader, and a final gate only you can pass before it ships.

refine-copy Core

Line-level suggestions against your rules. Never auto-applied — you accept or reject each one.

learn-from-edits Learn

Compares what it drafted with what you published, finds what you keep changing, and proposes rule updates for you to approve.

repurpose-piece Reach

Turn one approved article into posts written for each platform — every field filled in and ready to paste, not a link dump.

outreach-copy Reach

Cold emails built from a real reason to reach out and checked against your rules — outreach that reads like a person and earns a reply.

content-strategy Reach

A keyword-led plan for what to write: topics grouped into themes, one search phrase per piece, built so the articles keep earning traffic long after you publish.

How it works

Three steps, then it compounds.

Step 01

Lock your voice

Run voice-setup. It writes VOICE-RULES.md and copylock.json into your project — the rules every skill reads.

Step 02

Draft and refine

Write with your rules enforced, not suggested. The copy gate holds; nothing publishes without your sign-off.

Step 03

Let it learn

Edit as you normally would. learn-from-edits watches the difference and proposes rule changes you approve.
