# OSINT Investigation — Public Records Cross-Reference

Investigative framework for public-records OSINT: government contracts,
corporate filings, lobbying, sanctions, offshore leaks, property records,
court records, web archives, knowledge bases, and global news. Resolve
entities across heterogeneous sources, build cross-links with explicit
confidence, run statistical timing tests, and produce structured evidence
chains.

**Python stdlib only.** Zero install. Works on Linux, macOS, Windows. Most
sources work with no API key (OpenCorporates has an optional free token
that raises rate limits).

Adapted from the MIT-licensed ShinMegamiBoson/OpenPlanter project; expanded
to cover identity / property / litigation / archives / news sources that
the original didn't address.

## When to use this skill

Use when the user asks for:

- "follow the money" — government contracts, lobbying → legislation, sanctions
- corporate due diligence — who controls company X, where are they
  incorporated, who serves on their boards, what filings have they made
- sanctions screening — is entity X on OFAC SDN, ICIJ offshore leaks
- pay-to-play investigation — contractors with offshore ties, lobbying
  clients winning awards
- property ownership — find recorded deeds/mortgages by name or address
  (NYC; for other counties point users at the relevant recorder)
- litigation history — find federal + state
