    Brand Voice Guide Builder

    Example session with this skill installed

    Define a voice for a dev-tool startup. We are technical but not stuffy. We value brevity. Here is a blog post and an email we sent. We hate the word 'leverage'.

    • Read your context and instructions
    • Compiled the brand voice guide

    I have analyzed the blog post and email provided. The voice is high-certainty and low-warmth, prioritizing technical accuracy over friendly padding.

    Brand Voice Guide: Dev-Tool Startup

    1. Voice Dimensions

    DimensionScoreReasoning
    Formality2/5Uses technical shorthand and contractions; avoids corporate jargon.
    Warmth2/5Minimalist and efficient. Respects the reader's time by getting out of the way.
    Certainty4/5Avoids "we believe" or "it seems." States technical facts as absolute.
    Energy4/5Short, punchy sentences. Rapid-fire information delivery.

    2. Sentence Rules

    • Average sentence length under 15 words.
    • No exclamation marks.
    • Headings must be imperative verbs (e.g., "Install the CLI," not "Installation").
    • Use "we" for the company and "you" for the developer.
    • Never use "leverage," "seamless," or "robust."
    • Start paragraphs with the conclusion.

    3. Execution Samples

    4. AI Instruction Block

    Write in this voice: Formality 2/5 (casual but technical), Warmth 2/5 (direct), Certainty 4/5 (authoritative), Energy 4/5 (punchy). 
Use: 'CLI', 'deploy', 'latency'. Avoid: 'leverage', 'solution', 'robust'. 
Sentence average <15 words. No exclamation marks. Headings are actions. 
Example: "Build APIs in seconds, not hours."

    Next steps

    2. Distribute the 12 execution samples to your support team to align their tone.
    3. Replace the 'Before' hero line on your landing page with the 'After' version.

    About this skill

    The problem

    Most brand voice guides are vague collections of adjectives like "professional" or "bold" that don't help writers make decisions. Inconsistent copy across product UI, support, and marketing dilutes brand identity and confuses users.

    What it does

    • Maps your brand across four concrete scales: Formality, Warmth, Certainty, and Energy, providing specific reasoning for each position.
    • Generates a three-column word list of precise terms to use, industry clichés to avoid, and absolute banned words.
    • Establishes checkable sentence rules (e.g., word counts, active voice, heading styles) that a reviewer can verify against any draft.
    • Produces twelve before-and-after rewrites across critical touchpoints like error messages, pricing pages, and sales emails.
    • Outputs a ready-to-use LLM instruction block to ensure AI tools write in your specific brand voice.

    Why this beats prompting it yourself

    General prompts often produce generic "corporate-friendly" output that lacks character. This skill forces specific positions on a scale and provides "show, don't tell" examples that make the voice falsifiable and teachable to both humans and LLMs.

    Use cases

    • Standardizing copy across a decentralized team of freelance writers.
    • Refining AI-generated drafts to sound like a specific founder or brand.
    • Hardening customer support responses for high-stress situations like outages.
    • Onboarding new hires with a one-page "cheat sheet" for company communications.

    Known limitations

    Requires at least one sample of existing writing or a detailed description to function. Effectiveness scales with the quality of negative samples (writing the user dislikes) provided during intake.
