NDA Triage Checklist

Mutual vs. one-way obligations, definition scope, carveouts, term and survival periods, termination rights — each item flagged as standard, needs attention, or missing.

Severity-by-likelihood framework that surfaces risk factors for lawyer review. Consistent output format every time.

Open-Source Foundation

Built on the official open-source legal plugin content from Anthropic's knowledge-work-plugins repository (Apache-2.0 License).

Active Upstream Contributions

We contribute safety improvements back to the Anthropic repo. PR #6 refined terminology to ensure defensible, non-advisory output.

When Teams Use Legal Plugin Playbooks

NDA Review for Small Businesses

Get a structured triage of any NDA before signing. Know which terms are standard and which need attorney attention.

Forward the vendor NDA to junior@usejunior.com and review the checklist before your call tomorrow.

In-House Counsel First Pass

Use standardized checklists as a first pass before detailed attorney review. Focus human time on the items that need attention.

Run the new supplier agreement through the NDA triage checklist and flag anything non-standard.

Legal Ops Standardization

Ensure every contract gets the same structured review, regardless of who handles it. Consistent output format for comparison across deals.

We need all NDAs reviewed against the same checklist before they go to the partner for sign-off.

Risk Prioritization

The severity-by-likelihood framework helps teams focus on the risks that matter most. No more guessing which issues to escalate.

Classify the risk factors in this services agreement so I know what to bring up in the negotiation.

Built on Open Source

This implementation is powered by the open-source legal plugin content from Anthropic's knowledge-work-plugins repository (Apache-2.0 License).

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.
