Credibility Evidence Selector

When to Use

You have a claim a skeptical audience might reject, and a bag of possible proof points (stats, quotes, stories, demos, details). You need to decide which evidence to lead with — and which to cut. This skill ranks evidence across six named credibility sources and applies the Sinatra Test as a pass/fail filter to kill weak chains before they reach the audience.

Run this skill when the user is about to ship a claim without thinking hard about why the audience would believe it. Run it BEFORE writing the final copy, not after — the choice of evidence type reshapes the whole paragraph.

Preconditions to verify before starting:

• You know the specific claim. If missing, ask: "What is the exact one-sentence claim you need the audience to believe?"
• You have an evidence inventory (even a rough list). If missing, ask: "What proof points do you have — stats, stories, customers, experts, demos, details?"
• You know the audience's default skepticism. If missing, ask: "Who is judging this, and what is the one thing they'd say to dismiss it?"

Do NOT use this skill for:

• Fabricating evidence. This skill ranks what exists; it never invents sources.
• Designing experiments or user studies.
• Extracting the core message (use core-message-extractor first — credibility is applied to a core, not in place of one).
