Why This Exists

I was reviewing real contracts — NDAs, SaaS agreements, M&A docs, merchant agreements — and wanted AI assistance directly in my coding workflow. So I researched what was available:

• Commercial legal AI (Kira, Ironclad, LegalOn, Harvey, Spellbook) — enterprise-only, custom quotes, no API access for individual developers
• Open source tools (LexNLP, OpenContracts, LawGlance) — incomplete projects requiring significant integration work, none designed for AI coding assistants
• Generic contract checklists — one-size-fits-all reviews that don't differentiate between an NDA and an M&A agreement, give the same advice to buyers and sellers, and say "negotiate this" without telling you what to ask for

Nothing worked as a drop-in skill. So I built one grounded in the CUAD dataset (41 legal risk categories from 510 real contracts), tested it against actual agreements, and iterated until the output was useful for real negotiations.

The result: position-aware review with market benchmarks, document-type checklists, and actual redline language — not just a list of issues.

What It Does

Analyzes legal contracts and outputs:

• Risk assessment with severity ratings (🔴 Critical / 🟡 Important / 🟢 Acceptable)
• Red flags quick scan — instant danger sign detection
• Key terms table with section references
• Market standard benchmarks — how terms compare to industry norms
• Negotiability ratings — what's realistic to change given power dynamics
• Specific redlines — actual replacement language, not just "negotiate this"
• Missing provisions with suggested language to add
• Internal consistency checks (broken cross-references, undefined terms)

Generate Deliverables with legal-redline-tools

This skill outputs structured JSON redlines. To produce the tracked-changes Word docs and redline PDFs that lawyers actually send, pair with legal-redline-tools:

pip install git+https://github.com/evolsb/legal-redline-tools.git

# After the skill generates redlines.json:
legal-redline apply contract.docx redlined.docx \
    --from-json redlines.json \
    --pdf redline.pdf \
    --memo-pdf internal-memo.pdf

Position-Aware Review

Tell it which party you are (customer, vendor, buyer, seller, receiving party) — the skill adjusts what it flags as risky.
