# Creator Authenticity Score

> Vet Instagram creators before a sponsorship: view-based engagement rate, bot share of comments, and a 0-100 authenticity score for one creator or a list.

The Creator Authenticity Score skill scores Instagram creators on what a sponsor actually buys: real engagement, measured against views rather than follower count, and a real audience, measured as the bot and spam share of their comments. It works for a single creator or a batch of handles, and always shows the components next to the score. It is a screening heuristic for shortlisting and comparison, not a fraud verdict.

## Example Prompts

* "Is @\[handle]'s audience real?"
* "Check engagement quality for @\[handle]"
* "Vet these three creators before we sign them: @a, @b, @c"
* "Rank these 10 Instagram handles by authenticity"

## Scoring Methodology

<Steps>
  <Step title="Resolve the creator">
    Look up the profile by username: follower and following counts, post count, verified and private status. Private accounts are reported as "cannot screen" rather than scored.
  </Step>

  <Step title="Measure real engagement">
    Pull the 50 most recent posts and compute likes plus comments over video plays. Views are the hardest number to fake. Accounts with no video plays fall back to a follower-based rate, flagged as lower confidence. A like-to-comment ratio above 50:1 is a soft flag, since engagement pods buy likes, not comments.
  </Step>

  <Step title="Read the audience">
    Pull up to 200 comments on each of the top 3-5 posts and compute the bot ratio from Xpoz's spam detection, pooled across the sample. If comments are unavailable, the creator is scored on engagement only and marked partial.
  </Step>

  <Step title="Score">
    A 0-100 authenticity score: 40% engagement rate (scaled by follower tier), 40% audience authenticity (100 minus bot share), 20% sanity checks (following/follower ratio, post count relative to audience size, like-to-comment flag). Rounded to a whole number, never presented as precise.
  </Step>

  <Step title="Report">
    A single creator gets a short card with a one-line verdict. A batch gets a comparison table sorted by score, with private and partial creators listed separately.
  </Step>
</Steps>
