ShopiTrust

A Claude Code skill that scores your trust battery with a colleague and gives you one specific, actionable tip to improve it — grounded in real signals from Slack, email, and calendar.

What is a trust battery?

A Shopify concept: every working relationship has a charge level. It goes up when you do what you say, respond quickly, give credit, and close loops. It goes down when you don't.

How it works

Every relationship starts at 0.5 (neutral). Based on real interaction signals, the score moves up or down:

• Charging signals (+0.05 to +0.08 each): quick responses, closed loops, acknowledging someone's work, regular 1:1 cadence, proactive info sharing
• Draining signals (-0.05 to -0.10 each): unanswered messages, broken commitments, cancelled meetings
• No interaction → stays at 0.5, no penalty. The first interaction is an opportunity, not a deficit.

Then you get one tip — specific to what was actually found, not generic advice.

Example output

Trust Battery: Sean Kelly
Score: 0.42 ▓▓▓▓░░░░░░

🟡 Below neutral — room to grow

What moved it: There's an unanswered Slack message from him 3 days ago
asking for your read on the identity_v1 cost tradeoff.

Today's tip:
Reply to Sean's Slack message from 3 days ago — he asked for your
read on the identity_v1 cost tradeoff and hasn't heard back.

Why this matters:
Unanswered asks are the fastest way to drain a trust battery. This
one is yours to close.

Quick Site (Browser UI)

A browser-based version lives in site/index.html — deploy it to Shopify's internal Quick platform so anyone can use it without Claude Code.

Deploy to Quick

# One-time setup
quick auth
quick init   # generates the Quick SKILL.md — prevents API hallucination

# Deploy (run from the site/ directory)
cd site
quick deploy . shopitrust

The site will be live at shopitrust.quick.shopify.io.

What it uses

Quick API	Used for
quick.ai	Calls Claude (no API key needed — billed to corpo)
quick.id	Gets the current user's name, email, Slack handle
quick.slack	DMs the result to the user's own Slack

Develop locally

cd site
quick serve

Opens at localhost:3000 — hot reloads on save.
