leads skillA

leads is agent-read markdown (skill) from greglas75/zuvo: B2B lead discovery and enrichment skill. Finds company addresses, employee emails, and phone numbers filtered by industry, geography, role, and company size. 100% free-tier: orchestrates Claude Code's native WebSearch and WebFetch plus free OSINT subprocesses (theHarvester, crt.sh, whois, GitHub API, OSM Overpass, DNS MX, bash SMTP probe). No paid API keys required — optional env vars (ZUVO_HUNTER_KEY, ZUVO_APOLLO_KEY, ZUVO_GITHUB_TOKEN) are recognized as enhancers but never required. Hybrid mod.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
