Disclaimer: This skill provides general guidance on commercial contract structure and drafting best practices. It is NOT legal advice. Always have qualified legal counsel review contracts before signing or sending them to counterparties.
Commercial contracts are the binding agreements that govern business relationships. Good contracts prevent disputes by making expectations, obligations, and risk allocation explicit. This skill covers the structure, key clauses, and drafting process for the most common commercial agreements - NDAs, MSAs, SaaS subscriptions, licensing agreements, and data processing addendums - and the process of reviewing and redlining contracts received from counterparties.

Do NOT trigger this skill for:
Clarity over legalese - Plain language reduces disputes. Every obligation, right, and restriction should be understandable on first reading. If a clause requires a lawyer to decode, rewrite it. Legalese that obscures meaning creates ambiguity that parties exploit in disputes.
Define all terms - Every capitalized term must appear in a Definitions section or be defined on first use. Undefined terms invite competing interpretations. "Confidential Information," "Intellectual Property," "Affiliate," and "Services" are the most commonly contested undefined terms.
Risk allocation must be explicit - Contracts exist to allocate risk. Who bears the cost of a data breach? Who indemnifies whom for IP infringement claims? What is the liability cap? If risk allocation is implicit or absent, courts default to interpretations that may not match what either party intended.
Standard terms reduce negotiation - Using market-standard positions (e.g., mutual NDA, uncapped IP indemnity, 12-month liability cap for SaaS) speeds up deals. Know which clauses are standard so you can focus negotiation energy on the genuinely non-standard asks.
Version control everything - Every draft should be dated and versioned. Track changes between drafts. Maintain a redline history. In a dispute, the negotiation history can be used to interpret ambiguous terms (the "course of dealing" doctrine).
Every commercial contract shares a common skeleton:
Indemnification - Party A agrees to defend and pay costs if Party B is sued by a third party because of Party A's breach or IP. Usually mutual for IP, one-sided for gross negligence.
Limitation of liability - Caps total recovery at a multiple of fees paid (12 months is standard for SaaS). Always carve out: death/personal injury, willful misconduct, confidentiality breaches, and IP indemnity from the cap.
Representations and warranties - "We represent that our software does not infringe third-party IP." Breach of a warranty triggers indemnification or termination rights.
Governing law and jurisdiction - Which state/country's law applies and where disputes are resolved. Avoid agreeing to the other party's home jurisdiction.
Assignment - Whether either party can transfer the contract to a third party (e.g., in a merger or acquisition). Standard position: neither party may assign without consent, except to an acquirer of all or substantially all assets.
| Risk | Typical allocation | |---|---| | IP infringement by vendor's product | Vendor indemnifies customer | | Customer's misuse of the product | Customer indemnifies vendor | | Data breach caused by vendor | Vendor liable, often uncapped | | Force majeure (pandemic, natural disaster) | Neither party liable | | Consequential damages | Mutually excluded (carve out fraud) | | Death / personal injury | Neither party may cap |
All changes to a signed contract must be in writing, signed by both parties, and reference the original agreement. Verbal amendments are unenforceable in most jurisdictions. Use a formal Amendment or Change Order template with a sequential number (Amendment No. 1, Amendment No. 2) to maintain a clear audit trail.
A mutual NDA protects confidential information exchanged in both directions. Key sections and what belongs in each:
1. Definition of Confidential Information
- Broad enough to cover all sensitive info
- Exclude: public domain, independently developed, received from third party,
required to be disclosed by law (with notice obligation)
2. Obligations of receiving party
- Use only for the Permitted Purpose
- Protect with at least the same care as own confidential info (not less than
reasonable care)
- Share only with employees/contractors on need-to-know basis
- Ensure recipients are bound by equivalent obligations
3. Term
- Duration of disclosure period (e.g., 2 years)
- Survival of confidentiality obligations (typically 3-5 years after expiry)
4. Return / destruction
- Upon request or expiry, return or certify destruction of materials
5. Remedies
- Acknowledge that breach causes irreparable harm - injunctive relief available
without bond requirement
Mutual NDA checklist:
A Master Services Agreement governs the overall relationship; Statements of Work (SOWs) or Order Forms attach to it for specific engagements.
MSA core sections:
IP ownership decision tree:
SaaS agreements govern access to hosted software. Key distinctions from on-premise licenses: customer never receives software copy; uptime and data portability matter.
Must-have SaaS clauses:
When reviewing a contract received from a counterparty:
Pass 1 - Commercial terms (business review)
Pass 2 - Risk clauses (legal review)
Redlining etiquette:
| License type | Key characteristics | Common use | |---|---|---| | Exclusive license | Licensor cannot grant same rights to others | Distribution deals, branded products | | Non-exclusive license | Multiple licensees allowed | Software, fonts, stock media | | Sole license | Only licensor and one licensee | Compromise between exclusive and non-exclusive | | Sublicensable | Licensee can grant rights to third parties | Platforms, resellers | | Perpetual | No expiration date | One-time software purchase | | Term | Expires on a date or event | SaaS, subscriptions |
Core license grant clause structure:
[Licensor] grants to [Licensee] a [exclusive/non-exclusive], [sublicensable/
non-sublicensable], [perpetual/term], worldwide license to [reproduce, distribute,
display, perform, modify] the [Licensed Materials] solely for [Permitted Purpose].
Every word in the grant clause matters. Omitting "modify" means licensee cannot create derivative works. Omitting "distribute" means they cannot share the output.
A Data Processing Agreement is required under GDPR Article 28 whenever a controller (customer) engages a processor (vendor) to process personal data.

Post-signature:
Renewal and renegotiation:
| Anti-pattern | Why it's wrong | What to do instead | |---|---|---| | Undefined capitalized terms | Creates ambiguity - court will interpret against drafter | Define every capitalized term in the Definitions section before using it | | Bilateral confidentiality with a residuals clause | Residuals lets receiving party retain and use "unaided memory" of confidential info, effectively gutting protection | Strike residuals clause or narrow it to specifically identified categories | | Uncapped mutual liability | Exposes both parties to unlimited damages for any breach | Set a mutual liability cap; carve out only specific high-severity scenarios | | Evergreen auto-renewal without notice window | Contract renews indefinitely; easy to miss cancellation deadline | Require 30-60 day advance notice to cancel; calendar the date immediately on signing | | Copying clauses from Google without understanding them | Boilerplate from the internet may not be enforceable in your jurisdiction or may create unintended obligations | Use a template reviewed by counsel in your jurisdiction; understand every clause before pasting | | No governing law clause | Court selects governing law, often unfavorably | Always specify governing law and preferred dispute resolution forum |
Residuals clauses gut NDA protection - A residuals clause allows the receiving party to use "information retained in the unaided memory of persons who have had access to confidential information." This effectively means any employee who read your confidential material can freely use it later. Always review NDAs for residuals clauses and strike or narrow them aggressively.
"Termination for convenience" asymmetry - Many vendor-drafted contracts include termination for convenience for the vendor but not the customer, or require 90-day notice from the customer but allow the vendor to terminate with 30 days. Review termination provisions for symmetry and ensure the notice period is practical for your transition timeline.
Auto-renewal with a short cancellation window - A contract that auto-renews annually with a 60-day cancellation notice is effectively a trap for busy teams. The renewal date must be calendared on signature day. A single missed deadline locks you in for another year.
"All IP created for customer" in MSAs - A customer-favorable MSA clause claiming ownership of all IP created during the engagement may inadvertently claim ownership of improvements to the vendor's core platform. Always carve out vendor's pre-existing IP and general platform improvements before agreeing to broad work-for-hire language.
Governing law ≠ dispute resolution venue - A contract can specify California law governs but require disputes be resolved in New York courts. These are separate clauses. Check both; agreeing to the counterparty's home jurisdiction for litigation is a significant concession.

Diátaxis-driven documentation writing, improvement, and auditing for AI agents. Writes public-facing product docs (tutorials, how-to guides, reference, explanation) and repo developer docs (README, CONTRIBUTING, ARCHITECTURE, ADRs, changelogs, runbooks), improves existing pages to their quadrant's standard, and audits whole doc sites against the Diátaxis map. Detects the docs stack (Fumadocs, Docusaurus, Starlight, MkDocs, VitePress, Mintlify, plain Markdown) and follows its conventions. Triggers on "write docs", "document this", "write a tutorial", "write a README", "improve this doc", "audit our docs", "restructure the documentation", or "absolute-documentations this".
development
End-to-end, phase-gated software development lifecycle for AI agents. Turns a ticket, task, plan, or migration into a validated design, a dependency-graphed task board, and verified code. Triggers on "build this end-to-end", "plan and build", "break this into tasks", "pick up this ticket", "grill me on this", "run this migration", "absolute-work this", or any multi-step development task. Relentlessly interviews to a shared design, writes a reviewed spec, decomposes into atomic tasks on a persistent markdown board, then peels tasks one safe wave at a time with test-first verification. Handles features, bugs, refactors, greenfield projects, planning breakdowns, and migrations.
development
Use this skill when building user interfaces that need to look polished, modern, and intentional - not like AI-generated slop. Triggers on UI design tasks including component styling, layout decisions, color choices, typography, spacing, responsive design, dark mode, accessibility, animations, landing pages, onboarding flows, data tables, navigation patterns, and any question about making a UI look professional. Covers CSS, Tailwind, and framework-agnostic design principles.
development
Autonomously simplifies code in your working changes or targeted files. Detects staged or unstaged git changes, analyzes for simplification opportunities following clean code and clean architecture principles, applies improvements directly, runs tests to verify nothing broke, and shows a structured summary with reasoning. Triggers on "simplify this", "refactor this", "clean up my changes", "absolute-simplify", "simplify my code", "make this cleaner", "tidy this up", "reduce complexity", "flatten this", "remove dead code", or when code needs clarity improvements, nesting reduction, or redundancy removal. Language-agnostic at base with deep opinions for JS/TS/React, Python, and Go.
