SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Writing messages that sound like a specific person is hard — generic AI output defaults to polished, hedged, corporate prose. This Skill encodes one person's actual writing style (distilled from 11,528 verbatim Slack messages) so drafts match his terse, blunt, Hebrew-English code-switching voice instead of sounding like a content team. ## Core Features & Use Cases - Voice-matched Slack drafting: Produces DMs, channel posts, and replies as 2-4 short burst messages with the correct language choice (Hebrew for Israeli 1:1s, English for channels) and signature patterns like spaced-hyphen connectors and one-word seals. - Situation-specific formulas: Covers critical feedback (gap + expectation), praise (short + specific + !), decisions (בוא נ… + seal), disagreement, and banter, each with real example messages. - Long-form register: Adapts the same voice to blog posts and long internal notes — composed English sentences that keep the dry humor, deadpan sarcasm, and verdict-first directness. - Use Case: You need to tell a report, as Aryeh, that a deadline slipped without warning. The Skill outputs a Hebrew burst: names the gap, states the expectation (פעם הבאה אני מצפה שתרים דגל בזמן), and closes flat — no sandwich, no hedging. ## Quick Start Ask the assistant to draft a Slack message as Aryeh to a specific person about your topic, for example: write a DM to Danny in my voice telling him the migration plan is over-scoped.

Frequently Asked Questions about stark-voice

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I write a Slack message in someone else's voice with AI?▼

Provide the AI with a style guide built from the person's real messages, covering language choice, message length, tone formulas, and banned patterns. This Skill encodes those rules from 11,528 verbatim messages so drafts match the target voice instead of defaulting to generic corporate prose.

How to draft feedback messages for Israeli colleagues in Hebrew?▼

Use Hebrew for 1:1 messages with Israeli colleagues, keeping English tech terms inline untranslated. State the gap directly, then the expectation with the formula 'פעם הבאה אני מצפה ש…', and send it as 2-4 short consecutive lines rather than one paragraph.

Can this voice style be used for long-form blog posts?▼

Yes, a dedicated long-form register adapts the voice to blog posts and long notes using composed English sentences. It keeps the dry humor, deadpan sarcasm, and verdict-first directness while dropping Slack bursts and Hebrew code-switching.

What are the limitations of AI voice-mimicry for workplace messages?▼

Voice mimicry only covers one specific person's style and fails when the output drifts into polished, hedged, corporate phrasing. It also requires the user to verify factual content and appropriateness, since the Skill controls tone and structure, not message accuracy.

Why do AI-drafted messages sound too formal or corporate?▼

Default language models add hedging phrases like 'happy to' and 'circling back', over-explain praise, and soften criticism with sandwiches. Counteract this with explicit rules: cut hedges, use one-word agreements, ration exclamation marks, and end with flat seals instead of softening questions.
