Contributing

The library lives at github.com/philterd/pii-redaction-policies. PRs welcome: bring your own vertical, your own custom identifiers, your own edge cases.

Why contributing matters

The library is more useful the more eyes are on it. Every policy you contribute saves another team (in healthcare, finance, legal, government, AI training) from rebuilding the same thing privately and often incorrectly. A rising tide lifts all boats.

  • You save peers time. A FERPA policy you write for K-12 student records is the starting point another district uses next week. A call-center PCI policy you tune today is the one a peer at a different bank doesn’t have to invent from scratch.
  • You get better policies. Public PR review pulls in compliance officers, security engineers, and practitioners from outside your team. Your draft comes out tighter than anything a single team would ship alone.
  • You get credit. Your name (or your org’s) lands in the policy’s author field and shows up on the policy’s page right here on philterd.ai. Durable attribution, not a buried changelog entry.
  • You compound the library. Healthcare PHI patterns inform finance NPPI work. Legal redaction patterns inform government FOIA prep. A contribution in one vertical strengthens the adjacent ones.
  • You make the whole ecosystem safer. Every team that adopts a vetted, peer-reviewed policy is one fewer team rolling their own regex and missing identifiers in production. Privacy is a collective-action problem; this is the collective action.

How review works

Every contribution gets reviewed for: schema compliance, sidecar metadata completeness, and golden-file validation against a representative input. See CONTRIBUTING.md for the file layout, metadata schema, and review process.

Policies must conform to the Phileas redaction policy JSON schema.

Need a policy that isn't here?

If you have a specific compliance framework or vertical use case in mind, the Philterd team can build a custom policy and tune it against your real data.
