The Segment-Level Win/Loss Autopsy
A segment-level win/loss autopsy of an Expandi campaign: who replied and who didn’t, cut by seniority, function, industry, size, geo and source, with honest sample-size grading, a proposed learnings-ledger diff, and a pre-registered next experiment. Use when reviewing what worked.

What it does
- Reconstructs which segments beat the baseline and which copy actually earned the replies.
- Declares upfront which of three evidence modes it is running in, gold, silver or bronze, and states that mode’s blind spot.
- Cuts performance by seniority, function, company size, industry, geography, and source, with a visible row for anything unknown.
- Suppresses any cell too small to call, and gates every claimed difference against a statistical noise threshold.
- Grades every finding by real evidence as A, B or C, and never lets a small sample drive a default.
- Proposes a learnings-ledger diff and a pre-registered next experiment, and writes nothing until you approve it.
Install
Pick your platform.
claude.ai
Settings → Capabilities → enable code execution → Skills → upload the zip. Team/Enterprise workspaces may need an org-level toggle enabled first; custom MCP connectors (for live Expandi access) need a paid plan.
Claude Code
Unzip into ~/.claude/skills/, Claude Code picks it up on its next run.
ChatGPT desktop
Install the zip in the ChatGPT desktop app (also Codex CLI and the IDE extension): Settings → Skills → Create → Upload the zip. ChatGPT on the web and on mobile runs plugin-bundled skills only. This library ships standalone zips, so there is no web or mobile install at launch; use the example prompts on this page there instead.
Codex
Unzip into ~/.agents/skills/, then invoke with $skill.
GitHub Copilot
Add the skill folder to .github/skills/ in the repo. Copilot also reads .claude/skills/ and .agents/skills/, so an existing install already works.
M365 Copilot
M365 Agent Builder (Frontier preview), when building or editing an agent, upload the zip as a skill.
Cursor
Unzip into .agents/skills/ in the repo, or ~/.cursor/skills/ for every project.
