Our Contributions
We're active contributors to this framework. Our PR #6 addressed safety by refining verbs like "assess risk" to "classify risk factors," ensuring the output remains focused on data classification rather than legal advice.
What the NDA Triage Checklist Covers
Every contract is analyzed against the standardized framework. Each item is flagged as Standard, Needs Attention, or Missing:
| Category | What It Checks |
|---|---|
| Obligations | Mutual vs. one-way confidentiality |
| Definitions | Scope of "confidential information" |
| Carveouts | Public info, prior knowledge, independent development |
| Term | Duration of agreement and survival period |
| Termination | Standard vs. non-standard termination rights |
| Return/Destruction | Obligations at agreement end |
Risk Classification Framework
The analysis includes a severity-by-likelihood matrix to help your legal team prioritize:
- Severity: The potential impact if the risk is realized
- Likelihood: The probability of the risk occurring
It surfaces consistent risk factors for lawyer review, ensuring nothing slips through the cracks.
