Browser Extension Builder

Scaffolds a working, local Chrome extension: it detects any LinkedIn profile, shows a floating panel with a "Reveal contact info" button, calls Explorium to return a verified email/phone/job title/company, and lets the user push that contact to HubSpot (with an editable field-mapping review first) or draft a personalized email in Gmail.

Unlike the workflow skills in this repo, which run a prospecting or enrichment task inside the current Claude Code session, this skill produces a standalone browser extension loaded via Chrome's "Load unpacked" — a real artifact the user keeps using, not a one-off list. Reach for enrich-contact or list-builder when the user wants a contact or list right now; reach for this skill (or lead-gen-tool-builder) when they want a tool.

No personal keys are stored in this skill. The bundled extension has no hardcoded credentials — both the Explorium key and the HubSpot token are pasted into the extension's own Options page at install time and stored in chrome.storage.local, local to the user's browser profile.
