Build a my-writing-style skill from your own prose.
Give it a few pieces of your writing — local files, URLs, or pasted text — and it measures word-level habits, runs a multi-agent pass over words, sentences, and passages, checks each habit with you, and writes a skill that Claude Code and Codex load automatically.
This is the same style-learning flow used in the DocWriter app.
Add the marketplace, then install the plugin. Use a session or the terminal — not both.
Either, in a Claude Code session:
/plugin marketplace add docwriter-org/style
/plugin install docwriter-style-generator@docwriter-style
Or, in the terminal:
claude plugin marketplace add docwriter-org/style
claude plugin install docwriter-style-generator@docwriter-styleEither, in a Codex session, run /plugins, add marketplace
docwriter-org/style, then install docwriter-style-generator.
Or, in the terminal:
codex plugin marketplace add docwriter-org/style
codex plugin add docwriter-style-generator@docwriter-styleRefresh the marketplace after we ship a change. Same choice: session or terminal.
Either, in a Claude Code session:
/plugin marketplace update docwriter-style
Or, in the terminal:
claude plugin marketplace update docwriter-styleEither, in a Codex session, open /plugins and refresh marketplace
docwriter-style.
Or, in the terminal:
codex plugin marketplace upgrade docwriter-styleIn Claude Code run /docwriter-style-generator. In Codex run
$docwriter-style-generator. Or just ask to learn your writing style — the
skill triggers automatically. Run it again to add a source or update the habits.
A separate skill at ~/.claude/skills/my-writing-style/ (Claude Code) and
~/.agents/skills/my-writing-style/ (Codex):
