A reusable Claude skill that captures your personal writing style and applies it consistently across every output. Define your voice once, load it at the start of any session, and everything Claude writes sounds like you.

cp SKILL.md .claude/skills/writing-voice/SKILL.mdOnce installed, say "use my voice", "apply my writing style", or "load my voice config" and Claude will either load your existing profile or walk you through building one from scratch. The profile persists in the skill file and loads in seconds on future sessions.
Claude's default writing is competent but sounds like Claude, not you. It uses em dashes, hedging phrases, and evaluative openers that may not match how you communicate.
Without a voice config, you re-explain your preferences every session. "Don't use bullet points." "Make it more direct." "Drop the em dashes." Every time.
Your memo voice is different from your Slack voice. A single "be more direct" instruction cannot capture that nuance. The profile handles both modes.
If you spend more time editing Claude's output than it would take to write from scratch, the voice profile is broken. This skill fixes it at the source.
Primary Audience (who you usually write for), Technical Level (business vs. technical default), Formal Document Structure (opening format, section headers, body format, how recommendations are presented), Informal Communication Style (length, tone, humor), and Voice Principles (the non-negotiable rules that apply everywhere).
Provide two to three examples of your writing and Claude will analyze them for sentence structure, vocabulary level, punctuation patterns, tone markers, and avoidance patterns. The extracted style rules get folded into your profile automatically.
"Never use em dashes. Restructure the sentence, use a semicolon, or use a colon." Specific, absolute, easy to follow. Not "minimize em dash usage."
"No evaluative openers: never write 'great question', 'important consideration', or 'it should be noted that.' Engage with the content directly." The ban list is often more defining than the preference list.
"Open formal documents with a title in subject-line format. No addressee block. First section covers situation and significance. Final section presents options ordered by preference. The reader makes the decision."
"Be more direct" is not a voice rule. It is too vague to produce consistent output. "Lead with the point. Context follows. No introductory framing." is a voice rule. Specificity is everything.
Banned phrases and constructions are often more defining than preferences. If you cringe when Claude writes "it should be noted that," put it in the ban list.
Most people write differently in a memo vs. a Slack message. The profile should capture both modes independently.
The first version will not be perfect. Use it for a session, note what feels off, refine the rules. A voice profile is a living document.
"Sound like a memo from a VP, not a blog post from a consultant" gives Claude a reference point. Vague instructions like "be professional" do not.
This skill defines a reusable writing voice that Claude applies to all outputs for the remainder of a session. It governs both formal documents (memos, proposals, reports, briefs) and informal communications (emails, Slack messages, quick updates).
Once loaded, confirm activation with a single brief sentence, then proceed with whatever the user needs.
A voice configuration is personal. Before generating anything, gather the following from the user.
Once inputs are gathered, the profile follows four sections: Audience Default (who the reader is and what register to use), Formal Document Rules (structure and tone for professional documents), Informal Communication Rules (structure and tone for messages), and Voice Principles (absolute rules that apply everywhere).
Each section contains specific, actionable rules. Not "be more direct" but "lead with the point, context follows, no introductory framing."
If the user provides writing samples, Claude analyzes them for: sentence structure and length, vocabulary level, punctuation patterns, paragraph structure, opening and closing patterns, tone markers, and avoidance patterns. These observations are synthesized into the four-section profile and presented for review.
Be specific about what you hate. Provide contrast ("memo from a VP, not a blog post from a consultant"). Separate formal and informal modes. Iterate after using it. Store it once, use it everywhere.
