Human Voice — Profession-Specific AI Writing Skills
Compact, profession-specific writing skills that teach an LLM how a real professional in that role actually communicates — not template AI prose.
A library of self-contained, platform-agnostic writing skills — one markdown file per profession, designed to stop AI-generated cover letters, proposals, and client emails from all sounding like the same brochure copy.
Background
AI writing tools default to a generic register: every cover letter leads with the wrong thing, every proposal reads like marketing copy, every client email sounds like a template. The fix isn’t a longer prompt — it’s giving the model a real professional’s voice: what to lead with, what to cut, what phrases to avoid.
Technical highlights
- Each skill is a single, dependency-free markdown file with a
ProfileandInstructionssection - Works as a system prompt, custom instruction, or
.claude/skills/<name>/SKILL.mddrop-in — no platform lock-in (ChatGPT, Claude, Cursor, Gemini) - Document-aware: a job-seeker skill distinguishes a cover letter from a recruiter follow-up from LinkedIn outreach, each with its own rules
- Skills ship with explicit banned-phrase lists, not just tone guidance
What I learned
Tone instructions (“write professionally”) don’t transfer between professions because professionals don’t share a voice — a consultant’s proposal and a job-seeker’s cover letter solve different trust problems. Encoding the purpose of each document type, not just a style adjective, is what actually changes output quality.
