Files
Contract Redliner
Read a contract and produce a contract-review.md with clause-by-clause analysis, risk ratings, replacement language in tracked-changes format, and negotiation talking points. Unlike contract-analyzer (which only flags issues), produce specific, drop-in replacement language for every problematic clause, ready for negotiation.
Contents
references/risk-categories.md-- the seven risk categories, what to look for in each, and the risk-rating system.references/redline-format.md-- per-issue redline entry format and tracked-changes conventions.references/output-template.md-- the fullcontract-review.mdstructure to generate.references/contract-types.md-- per-contract-type focus areas and worked examples.
Workflow
1. Ingest the contract. Accept pasted text, a file path (.txt, .md, .pdf, .docx), or a URL. Load files with the Read tool; for PDFs use the pdf skill or Read PDF support. Parse the full text and identify all numbered sections, clauses, and subclauses.
2. Identify type and parties. Determine contract type, Party A (drafter/company), Party B (signer), governing law, effective date, and term. Apply the matching focus area from references/contract-types.md.
3. Analyze every section. Evaluate each section against the seven risk categories in references/risk-categories.md. Assign each section a rating (CRITICAL / HIGH / MEDIUM / LOW / ACCEPTABLE). Mark fair sections as ACCEPTABLE with a brief note -- do not skip them.
4. Generate redlines. For every issue, produce a redline entry per the format and tracked-changes conventions in references/redline-format.md. Provide complete, standalone replacement language plus a clean accepted version.
5. Write `contract-review.md`. Generate the file in the working directory (or the directory the user specifies) following references/output-template.md exactly and in order.
Mandatory Rules
- Open every output with this disclaimer verbatim:
LEGAL DISCLAIMER: This analysis is informational only and does not constitute legal advice. Contract interpretation is jurisdiction-specific and fact-dependent. Always consult a qualified attorney before signing or modifying any legal agreement. This tool is designed to surface potential issues and suggest alternative language for discussion purposes only.
- Never provide incomplete replacement language; every redline includes a full, usable clause.
- Never present analysis without quoting the specific contract language being discussed.
- Never assume jurisdiction-specific enforceability; note when a provision's enforceability varies by jurisdiction.
- Always produce
contract-review.mdas the primary deliverable. - Always use tracked-changes format (
[-deletion-]/[+insertion+]) for every suggested change. - Always include negotiation talking points for every issue rated MEDIUM or above.
- Always analyze from the signing party's perspective unless told otherwise.
Quality Standards
- Be exhaustive. Review every section, not just the obviously problematic ones.
- Be specific. Quote exact language, reference exact section numbers, provide complete replacement text.
- Be practical. Frame suggestions a reasonable counterparty would accept; extreme positions undermine credibility.
- Be balanced. Note favorable provisions too -- this builds credibility for the items that need changing.
- Quantify where possible. Estimate liability exposure and calculate penalties when the contract permits.
- Reference market standards. When calling something non-standard, state what the market standard actually is.
Contract-Type Focus Areas
Adjust analysis focus based on contract type.
SaaS / Software Agreements
Prioritize: SLA terms, uptime guarantees, data ownership, data portability, API access post-termination, escrow provisions, security obligations, SOC 2 / compliance certifications, subscription auto-renewal, price escalation caps, usage-based pricing ambiguity.

NDAs / Confidentiality Agreements
Prioritize: Definition breadth of "confidential information," residual knowledge clauses, term duration, mutual vs. one-way obligations, carve-outs for required disclosures, injunctive relief provisions, return/destruction of information.
Master Service Agreements
Prioritize: SOW incorporation, change management, acceptance testing, warranty periods, liability allocation across SOWs, subcontracting rights, key personnel provisions, benchmark clauses.
Partnership / Joint Venture Agreements

Worked Examples
User: "Redline this SaaS agreement" Response: Read the agreement, identify it as a SaaS subscription contract, analyze all sections, flag the unlimited liability clause as CRITICAL, note the missing data portability provision, identify the 180-day auto-renewal notice as an AUTO-RENEWAL GOTCHA, produce replacement language for every issue, generate contract-review.md with full tracked changes and negotiation strategy.
User: "Here's my employment contract, mark it up" Response: Read the agreement, identify broad invention assignment covering all work including personal projects as CRITICAL IP RISK, flag the 24-month nationwide non-compete as CRITICAL UNFAVORABLE TERMS, note missing severance provisions as MISSING PROTECTION, draft narrowed replacement language for each, generate contract-review.md.
User: "Review and redline this vendor MSA" Response: Read the MSA, identify one-sided indemnification as HIGH LIABILITY EXPOSURE, flag the absence of a change order process as MISSING PROTECTION, note vague acceptance criteria as AMBIGUOUS LANGUAGE, highlight the cross-default provision linking all SOWs as a TERMINATION TRAP, produce redline for every section, generate contract-review.md with tiered negotiation strategy.

RISK CATEGORY: [One of the seven categories]
RISK RATING: [CRITICAL / HIGH / MEDIUM / LOW]
CURRENT LANGUAGE:
> "[Exact quote of the problematic clause from the contract]"

> "[The final suggested language as it would read after accepting all changes]"
NEGOTIATION TALKING POINT:
[1-2 sentences framing why this change is reasonable and how to present it
to the other party. Include leverage points and compromise positions.]Tracked-Changes Formatting Rules
Follow these conventions strictly:
1. Deletions: Wrap removed text in [- and -] markers
- Example:
[-The Company shall have sole discretion-]
2. Insertions: Wrap added text in [+ and +] markers
- Example:
[+Both parties shall mutually agree+]
3. Combined edits: Show deletion immediately followed by insertion
- Example:
[-sole discretion-] [+mutual written agreement+]
4. Preserve context: Include 5-10 words of unchanged text before and after each edit so the reader can locate the change in the original document.
5. One change at a time: If a clause has multiple issues, show each edit separately and then show the fully revised clause at the end.
6. Clean version: Always provide a "clean" version showing how the clause reads after all changes are accepted.
Risk Categories
Evaluate every section against these seven categories during clause-by-clause analysis (Step 3). Use the exact tags below when categorizing issues.
Tags:
UNFAVORABLE TERMS-- One-sided or disproportionate obligationsMISSING PROTECTION-- Standard safeguard not presentAMBIGUOUS LANGUAGE-- Vague, undefined, or inconsistent termsLIABILITY EXPOSURE-- Uncapped or excessive liability riskIP RISK-- Intellectual property assignment or licensing concernsTERMINATION TRAP-- Problematic termination or exit provisionsAUTO-RENEWAL GOTCHA-- Renewal terms that lock in or escalate
Category 1: Unfavorable Terms
Look for:
- One-sided obligations that benefit only the drafter
- Disproportionate penalties or remedies
- Unreasonable performance standards or SLAs with no reciprocal commitment
- Payment terms that disadvantage the signer (Net 90+, pay-when-paid)
- Unreasonable warranty disclaimers or limitations
- Broad representations and warranties required of only one party
- Fee escalation clauses with no cap or ceiling
- Most-favored-nation clauses that restrict pricing flexibility
- Exclusive dealing requirements with no reciprocal commitment
- Minimum purchase or volume commitments with no flexibility
Category 2: Missing Standard Protections
Look for the absence of:
- Liability caps (both aggregate and per-incident)
- Mutual indemnification (one-sided indemnification only)
- Force majeure clause
- Data protection and privacy provisions
- Insurance requirements
- Warranty of authority / capacity to contract
- Severability clause
- Entire agreement / integration clause

- Survival clause specifying which obligations continue post-termination
- Anti-assignment protections (or one-sided assignment rights)
- Governing law and venue selection
- Dispute resolution escalation procedures
- Confidentiality obligations (or mutual confidentiality)

- Waiver clause (no waiver by conduct)
Category 3: Ambiguous Language
Look for:
- Undefined key terms used throughout the contract
- Vague modifiers: "reasonable," "material," "substantial," "timely," "promptly" without defined timeframes
- Circular definitions or self-referencing clauses
- Conflicting provisions between different sections
- "Including but not limited to" used to expand scope unpredictably
- "Best efforts" vs. "commercially reasonable efforts" vs. "reasonable efforts" -- each carries different legal weight
- "May" vs. "shall" vs. "will" inconsistency
- References to external documents not attached or defined
- Catch-all phrases like "and/or," "etc.," "among other things"
- Pronouns with unclear antecedents in complex clauses
- Time references without specifying business days vs. calendar days
- "Discretion" or "sole discretion" granted to one party without standards
Category 4: Liability Exposure
Look for:
- Unlimited liability (no aggregate cap)
- Consequential damages not excluded or waived
- Broad indemnification obligations (defend, indemnify, and hold harmless)
- Indemnification for third-party claims without limitation
- Liability for acts of subcontractors or agents without recourse
- Joint and several liability provisions
- Personal guarantees embedded in business contracts
- No cap on indemnification obligations
- Liquidated damages clauses that function as penalties
- Representations and warranties that create strict liability
- Insurance requirements without corresponding liability limits
- "Gross negligence" and "willful misconduct" carve-outs that swallow the liability cap
Category 5: IP Risks
Look for:
- Overly broad IP assignment (all work product, including pre-existing IP)
- Work-for-hire provisions that capture background IP
- No carve-out for pre-existing intellectual property
- License grants that are irrevocable, perpetual, worldwide, and sublicensable
- No restrictions on derivative works from your deliverables
- Residual knowledge clauses that permit use of your proprietary methods
- No IP indemnification from the other party
- Moral rights waivers (relevant in some jurisdictions)
- Assignment of inventions not related to the contract scope
- No license-back for assigned IP needed to operate your business
- Background IP contamination risk (no clean-room provisions)
- Open source obligations that could infect proprietary work
Category 6: Termination Traps
Look for:
- Termination for convenience by one party only
- No right to cure before termination for cause
- Unreasonably short cure periods (less than 15 days for non-monetary, less than 5 days for monetary)
- Survival clauses that extend obligations indefinitely post-termination
- No pro-rata refund upon early termination
- Termination triggers that are vague or subjective ("dissatisfaction")
- Post-termination non-compete or non-solicitation that is overly broad
- Termination without notice provisions
- Wind-down obligations that are undefined or one-sided
- No transition assistance obligations
- Retention of deliverables or data by the other party post-termination
- Termination fees or penalties that exceed actual damages
- Cross-default provisions linking unrelated agreements
- Change of control termination rights for one party only
Category 7: Auto-Renewal Gotchas
Look for:
- Auto-renewal with no opt-out notice period
- Opt-out notice periods longer than 60 days before renewal date
- Renewal at increased rates without cap or notice
- Renewal term equal to original term (multi-year lock-in)
- Price escalation upon renewal with no cap
- Renewal terms that reset termination notice requirements
- Auto-renewal buried in boilerplate rather than highlighted
- No ability to modify terms upon renewal
- Renewal that resets minimum commitments or volume requirements
- Evergreen clauses with no termination mechanism
