Brand Designer skill by Sid Chaudhary

Context

  1. Check for .agents/product-context.md. If missing, ask the user to run /gtm:product-context first. If the user prefers to proceed without it, ask for the minimum required info inline: brand voice summary, ICP, and primary color.
  2. Read .agents/product-context.md for any existing brand voice notes.

Inputs

  1. Ask: "Paste 3-5 examples of your best content, the pieces that sound most like you." If fewer than 3 samples are provided, proceed but note that confidence in ratings is lower.

Process

  1. Read references/brand-voice-dimensions.md for the 6 voice dimensions and their rating scales.
  2. Analyze all content samples across the 6 voice dimensions:
    • Formality (1 = casual, 10 = formal)
    • Energy (1 = calm, 10 = high-energy)
    • Humor (1 = serious, 10 = playful)
    • Authority (1 = peer-level, 10 = expert)
    • Warmth (1 = detached, 10 = personal)
    • Complexity (1 = simple, 10 = technical)
  3. Rate each dimension 1-10 with a descriptive label (for example, a 7 paired with the label "Confident expert"). Keep the rating number and the label as separate values, never joined into one string with a dash.
  4. Identify vocabulary patterns: frequently used words, characteristic phrases, power words.
  5. Identify banned words or patterns: terms the brand avoids, cliches absent from samples.
  6. Determine jargon policy: does the brand use industry jargon freely, sparingly, or never?
  7. Analyze sentence structure: average sentence length, active vs. passive voice ratio, question frequency, use of fragments.
  8. Generate do/don't examples for each dimension: show a "sounds like us" and "doesn't sound like us" pair.
  9. Generate channel-specific adaptations: how the voice shifts for website copy, social media, email, and documentation.

Output

  1. Format the brand voice profile as:

Quality check before returning

  1. Before returning the output, verify:
  • Is every dimension in the Voice Profile table rated 1-10 with a descriptive label, not just a bare number?
  • If fewer than 3 samples were provided, is the lower-confidence note actually present in the output?
  • Does the Do/Don't table have at least one real pair per dimension, drawn from the samples, not invented examples?
  • Do the Channel Adaptations reference an actual pattern found in the samples rather than a generic statement that could apply to any brand?

If any check fails, correct it before returning the output.

  1. End every output with:
