Load Any CSV Into Expandi, Safely
Load a CSV into Expandi safely: preflight (profile-link validity, dedupe, explicit placeholder columns, 300-char cap), create the list, check headroom, wire auto-assign BEFORE the first add (it is not retroactive), chunk-add leads with placeholders, read-back verify, emit a launch manifest.

What it does
- Validates a CSV before Expandi ever sees it: LinkedIn URL format, duplicates, and any value over the placeholder character cap.
- Flags sensitive or irrelevant columns and only turns a column into a placeholder if you explicitly pick it.
- Resolves the seat and target campaign, warns you plainly if it’s already active, and works out how many leads it can still take, the 5,000 cap is per campaign, not just per list.
- Creates or tops up an Expandi-managed list and adds leads in resumable chunks, showing you a diff of any placeholder it would overwrite first.
- Checks headroom before wiring auto-assign, and translates it into plain terms, “your leads clear in about N days”.
- Reads the list back from Expandi itself to confirm added, skipped, and quarantined counts before calling it done.
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.
