nda-review-cli

Draft, review, and negotiate NDAs against your own house playbook. Deterministic by default; opt-in second-pass LLM adjudication via the model of your choice. Stdlib-only Python — single file, no SDKs, no telemetry.

Try it without installing

The full draft / review / simulator demo runs in a sandbox below — no install, no signup. Reset every 30 minutes.

What it does

• Drafts NDAs from bundled templates (mutual, one-way disclosing, Common Paper Mutual NDA Version 1.0). Outputs markdown plus a clean Word .docx.
• Reviews NDAs clause-by-clause against your policy with severity-scored findings, explainability evidence, and a deterministic risk score.
• Negotiates between two parties via a turn-taking, file-based protocol with hash-chained rounds, stance-driven amendments, fatigue concession to break stalemates, and a mandatory key-points sign-off before finalization.
• Learns counterparty profiles deterministically so repeat parties get a consistent stance.
• Optional LLM augmentation via Anthropic, OpenAI, Ollama, or any OpenAI-compatible endpoint — disabled by default, opt-in per-call with explicit consent.

Quickstart

The quickstart subcommand walks you through 16 questions to write your house policy. Each answer wires into the rule engine: clause keywords, preferred language, red-flag patterns, negotiation stance, clause priorities, non-negotiable redlines.

pipx install nda-review-cli

Drafting

Three bundled templates, plus --template-file to bring your own.

# Common Paper Mutual NDA — bundled, CC BY 4.0, attribution preserved
nda-review-cli draft --template common-paper-mutual \
  --party-a "Acme Inc." --party-a-address "123 Main St" \
  --party-b "Beta LLC"  --party-b-address "10 Market Way" \
  --purpose "evaluating a partnership" \
  --governing-law "California" \
  --out output/nda.md \
  --out-docx output/nda.docx \
  --review-after

Reviewing

Score any NDA against your policy. --why adds explainability evidence (matched clause keywords, paragraph index, confidence). --llm anthropic (or any other supported provider) layers in a second-pass adjudication that votes on findings, adds ones the rules missed, and proposes replacement clause language for high-severity items.

  --counterparty "Vendor Co" --learn-profile \
  --out-md output/review.md

Two-party negotiation

File-based protocol — single JSON document bounces between you and the counterparty by any channel (email, Drive, Git). Each round is signed by exactly one party and hash-chained so tampering is detected on load. See the workflow page for the full sequence.

Three counter modes: hand-written amendments (--amendments-file), deterministic stance-driven (--auto), or LLM-driven (--agent --llm). All accept --dry-run to preview without signing the round.

Stance, priorities, and the game-theoretic story

Each party picks a stance (conservative, middleground, or compromising) and ranks clauses 1..N by importance. Stance defines how many clauses you insist on; priorities define which ones. Clauses in your bottom-K concession zone get accepted regardless of stance. Logrolling resolves cross-party disputes when priorities differ — and they essentially always differ.

For the rare pathological case of identical priorities + symmetric stances, fatigue concession kicks in: after a clause has bounced past max_clause_bounces (default 4), the next proposer is force-conceded deterministically. The stalemate detector still trips for hard non-negotiable conflicts and surfaces them for human escalation rather than auto-resolving.

Finalize: hand off to your own PDF + signing tools

negotiate finalize emits the agreed .md + .docx. Optionally pass --to-pdf --sign and the CLI shells out to user-configured commands in config/integrations.json. Wire it to docx2pdf-cli and sign-cli for the full pipeline, or any other tool of your choosing.
