DINGDUFF SKILLS LICENSE 1.0

Version 1.0 · https://www.dingduff.com/skills-license/1.0 · Copyright © 2026 DingDuff Inc. All rights reserved.

The short version

This summary is for orientation only. It is not the license, it is not part of it, and where the two differ the terms below control.

Acceptance

In order to get any license under these terms, you must agree to them as both strict obligations and conditions to all your licenses. If you do not agree to these terms, do not download, install, use, or distribute the Skills.

What These Terms Cover

These terms cover the Skills — the skill packages DingDuff makes available under this license, whether you get them as a .skill file, through a plugin marketplace, from a DingDuff repository, from someone else who passed them along, or any other way. They cover each Skill on its own and the library as a whole, in every form: the SKILL.md files and their instructions and prompts, the reference files, the templates, the scripts and other code, the review panels and their markup, and everything else packaged with them. They cover updated versions of the Skills you receive, unless DingDuff provides that version under different terms.

The licensor grants you a copyright license for the Skills to do everything you might do with the Skills that would otherwise infringe the licensor's copyright in them, for any permitted purpose. However, you may only make changes and new works based on the Skills according to Changes and New Works, and you may only distribute the Skills according to Distribution License and Conditions on Distribution.

Copies You Need in Order to Use the Skills

Your copyright license covers every copy that using the Skills requires or ordinarily involves. That includes downloading the Skills; installing and reinstalling them; cloning or syncing a repository or marketplace that carries them; loading them into the context of an AI model; copies made automatically by the AI platform, plugin manager, marketplace, or operating system you use to install or run them; copies your organization's personnel and contractors make for their own permitted use; and reasonable backup and archival copies.

Making these copies is not distributing the Skills.

Permitted Purposes

Your own use and your organization's use. Use of the Skills for your own purposes and for the operations of your organization is use for a permitted purpose. This includes use in the practice of law and in work you are paid for — research, analysis, drafting, cite-checking, and any other work you perform for your own clients or your organization's clients.

Academic use. Use by an individual who is enrolled as a student in, employed as faculty by, or engaged as a researcher by an accredited institution of higher education in the United States is use for a permitted purpose, when it is solely for that individual's own noncommercial academic purposes — coursework, class assignments, teaching, scholarship, exam preparation, and academic research and study. This exception tracks the academic exception in the DingDuff Terms of Service and carries the same limits: it does not reach commercial use, or use in connection with an actual legal matter, the provision of legal services or legal advice to any client, or the representation of any client, including under any student-practice rule.

Commercial Use Is Permitted; Commercial Distribution Is Not

Read this before you read Distribution License.

The noncommercial limit in these terms applies only to passing the Skills to other people. It is not a limit on your own use. You may use the Skills in paid work, in a for-profit firm, and for paying clients, without restriction under these terms, and you never owe the licensor anything for doing so.

What you may not do is make money from the Skills themselves.

Changes and New Works

The licensor grants you an additional copyright license to make changes to the Skills, and new works based on them, for any permitted purpose — adapting them to your jurisdiction, your practice area, your house style, or your workflow.

You may keep your Modified Skills to yourself. If you pass them on, Distribution License, Conditions on Distribution, and Same Terms Downstream apply.

Distribution License

The licensor grants you an additional copyright license to distribute copies of the Skills and copies of your Modified Skills — but only noncommercially, and provided that you comply with every condition in Conditions on Distribution.

Noncommercially means you do not charge for the copy and do not receive money or anything else of value in exchange for it, for access to it, or as a condition of getting it. Recovering no more than your actual out-of-pocket cost for a physical medium is not receiving value. Bundling the Skills into something you sell, or offering them as an inducement to buy something you sell, is not noncommercial.

Running the Skills for other people counts as distribution. Operating the Skills so that people outside your organization get their benefit — as a product, service, platform, or feature of any of these — is distribution under these terms, whether or not anyone receives a copy. It is permitted only if it is noncommercial and meets the conditions below.

Sharing the Skills among your organization's own personnel and contractors, for their permitted use, is not distribution and these conditions do not apply to it.

Conditions on Distribution

Every copy you distribute — modified or not — must meet all of the following.

These are conditions, not covenants. Each numbered item below is an express condition precedent to your license to distribute. Your license to distribute a copy does not vest unless every condition is satisfied as to that copy, and terminates automatically as to that copy if any condition is not satisfied. They are not promises for which damages are the remedy, and nothing in these terms should be read to make them promises.

Distributing a copy that does not satisfy every condition below is outside the scope of your license entirely, and infringes the licensor's exclusive rights to prepare derivative works and to distribute copies under 17 U.S.C. § 106(2) and § 106(3). Each condition below exists precisely to govern the exercise of those two rights.

  1. Include these terms. The copy must contain these terms in full, or the URL for them above, both in the copy itself and in any package, archive, or repository you distribute it in.

  2. Keep the notices. The Skills' copyright, authorship, version, and license notices must be intact and legible. You may not remove, alter, or obscure them.

  3. Credit DingDuff. You must identify DingDuff Inc. as the original author of the Skills and link to https://www.dingduff.com/skills-license/1.0 or https://www.dingduff.com.

  4. Mark your changes. If the copy is a Modified Skill, you must state — prominently, in the copy itself and anywhere you offer it — that it is a modified version, that it is not official and not endorsed by DingDuff Inc., and, in general terms, what you changed.

  5. Pass on the same terms. The copy must reach its recipient under these terms. See Same Terms Downstream.

Same Terms Downstream

Any copy of a Skill or a Modified Skill that you distribute is subject to these terms in full, and you must make it available to your recipient under these terms. Your recipient's licenses come from the licensor directly, on these terms; you are not sublicensing.

How far this reaches. These terms attach to the Skills, to your Modified Skills, and to anything else you create that is substantially derived from them. They do not attach to Your Own Material — files, skills, tools, or other works you created yourself that are not derived from the Skills — merely because you distribute it alongside a Skill, or in the same package, archive, repository, or library. Your Own Material remains yours, on whatever terms you choose.

Notices

You must keep the Skills' copyright, authorship, version, and license notices intact and legible in every copy you make and in every Modified Skill you create, whether or not you distribute it. You may not remove, alter, or obscure them.

Your Work Product

The licensor claims no rights in what you produce with the Skills. Memoranda, briefs, motions, letters, research, and any other work product you generate using the Skills are yours. These terms require no attribution in your work product, and give the licensor no license to it. The conditions in these terms apply to distributing the Skills, never to distributing your work product.

Trademarks

These terms grant you no license to the DingDuff name, the DingDuff logo, or any other DingDuff trademark, service mark, or trade dress. You may accurately state that a Modified Skill is based on the DingDuff Skills — indeed, Conditions on Distribution requires you to say so. You may not use DingDuff's marks to name or brand a Modified Skill, or to promote it in a way that suggests DingDuff produced or endorsed it.

What These Terms Do Not Restrict

These terms restrict only what the licensor's rights in the Skills allow the licensor to restrict.

Fair use. You may have "fair use" rights for the Skills under the law. These terms do not limit them.

Ideas and methods. The licensor claims no rights in the legal methods, doctrines, analytical frameworks, research techniques, drafting conventions, or citation rules that the Skills describe or apply, or in any other idea, procedure, process, or system contained in them. Nothing in these terms prevents you from reading the Skills, learning from them, and applying what you learn in your own practice, your own writing, or your own materials.

No tying. Your licenses under these terms are not conditioned on your use of the DingDuff connector or any other DingDuff product or service, and nothing in these terms restricts your use of any competing product or service. Some Skills call the DingDuff connector and will not do much without it; that is a matter of how they function, not a condition of your license.

Your own materials. Nothing in these terms restricts anything you wrote or anything you obtained independently of the Skills.

No Other Rights

These terms do not allow you to sublicense or transfer any of your licenses to anyone else, or prevent the licensor from granting licenses to anyone else. These terms do not imply any other licenses.

Relationship to the DingDuff Terms of Service

These terms govern the Skills. The DingDuff connector, platform, and service are governed separately by the DingDuff Terms of Service at https://www.dingduff.com/terms, and most of the Skills require the connector in order to be useful. As to the Skills themselves, these terms control over anything inconsistent in the Terms of Service.

The Skills are a tool for lawyers. They are not legal advice and do not constitute the practice of law, the licensor is not a law firm, and no attorney-client relationship arises between you and the licensor. The Skills instruct an AI model, and an AI model can be wrong. You remain solely responsible for independently verifying every authority, quotation, and conclusion before relying on it, and for meeting your own professional obligations.

If you received a Modified Skill from someone other than the licensor, the licensor did not write it, has not reviewed it, and is not responsible for it.

NO WARRANTY

The Skills come as they are. The licensor does not promise that they work, that they are right, or that they suit anything you have in mind. You are the lawyer. The Skills are a tool.

THE SKILLS ARE PROVIDED "AS IS" AND "AS AVAILABLE," WITH ALL FAULTS AND WITHOUT WARRANTY OR CONDITION OF ANY KIND, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE. TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE LICENSOR DISCLAIMS ALL WARRANTIES AND CONDITIONS, INCLUDING ANY IMPLIED WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, ACCURACY, COMPLETENESS, RELIABILITY, SYSTEM INTEGRATION, AND QUIET ENJOYMENT, AND ANY WARRANTY ARISING FROM COURSE OF DEALING, COURSE OF PERFORMANCE, OR USAGE OF TRADE.

THE LICENSOR DOES NOT WARRANT THAT: (A) THE SKILLS, OR ANYTHING PRODUCED WITH THEM, WILL BE ACCURATE, COMPLETE, CURRENT, RELIABLE, OR ERROR-FREE; (B) ANY CASE, STATUTE, REGULATION, RULE, OR OTHER AUTHORITY IDENTIFIED, QUOTED, SUMMARIZED, OR VERIFIED WITH THE SKILLS IS CORRECTLY STATED, STILL GOOD LAW, NOT OVERRULED, SUPERSEDED, AMENDED, OR LIMITED, OR APPLICABLE TO ANY JURISDICTION OR MATTER; (C) ANY CITATION CHECK, VALIDITY CHECK, OR OTHER VERIFICATION PERFORMED WITH THE SKILLS WILL DETECT EVERY ERROR, OMISSION, MISQUOTATION, FABRICATION, OR ADVERSE AUTHORITY; (D) THE SKILLS WILL OPERATE WITHOUT INTERRUPTION OR MEET YOUR REQUIREMENTS; OR (E) ANY DEFECT WILL BE CORRECTED. THE LICENSOR MAKES NO REPRESENTATION REGARDING PRIVILEGE, CONFIDENTIALITY, OR WORK-PRODUCT PROTECTION.

NO LIABILITY

TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT WILL THE LICENSOR PARTIES BE LIABLE TO YOU OR TO ANY OTHER PERSON FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR RELIANCE DAMAGES, OR FOR ANY LOST PROFITS, LOST REVENUE, LOST GOODWILL, LOST DATA, LOST BUSINESS OPPORTUNITY, LOST OR TERMINATED CLIENT RELATIONSHIPS, INJURY TO PROFESSIONAL REPUTATION, COST OF SUBSTITUTE PRODUCTS OR SERVICES, COURT SANCTIONS, FEE FORFEITURE OR DISGORGEMENT, OR MALPRACTICE OR DISCIPLINARY EXPOSURE, ARISING OUT OF OR RELATING TO THESE TERMS, THE SKILLS, ANY MODIFIED SKILL, OR ANYTHING PRODUCED WITH ANY OF THEM, UNDER ANY THEORY OF LIABILITY — CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY, WARRANTY, STATUTE, OR OTHERWISE — EVEN IF A LICENSOR PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, AND EVEN IF ANY LIMITED REMEDY FAILS OF ITS ESSENTIAL PURPOSE.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE AGGREGATE LIABILITY OF THE LICENSOR PARTIES ARISING OUT OF OR RELATING TO THESE TERMS, THE SKILLS, OR ANY MODIFIED SKILL WILL NOT EXCEED ONE HUNDRED U.S. DOLLARS ($100), IN THE AGGREGATE AND NOT PER CLAIM. YOUR SOLE AND EXCLUSIVE REMEDY IF YOU ARE DISSATISFIED WITH THE SKILLS IS TO STOP USING THEM.

Basis of the bargain. You receive the Skills free of charge. The disclaimers and limits in these terms are an essential element of the exchange, they are what makes it possible for the licensor to give the Skills away, and the licensor would not make the Skills available without them. They apply notwithstanding any failure of essential purpose of any limited remedy, and they survive termination of your licenses.

Modified Skills and copies from other people. The licensor did not write, has not reviewed, and is not responsible for any Modified Skill made by anyone else, or for any copy you received from anyone other than the licensor. The disclaimers and limits above protect the licensor, and they also protect, to the same extent and as to claims by the people they distributed to, any person who distributes the Skills or a Modified Skill in compliance with these terms.

INDEMNIFICATION

If what you do with the Skills draws the licensor into someone else's dispute, that is yours to carry, not the licensor's.

YOU WILL INDEMNIFY, DEFEND, AND HOLD HARMLESS THE LICENSOR PARTIES FROM AND AGAINST ANY AND ALL CLAIMS, DEMANDS, ACTIONS, SUITS, PROCEEDINGS, INVESTIGATIONS, GRIEVANCES, LOSSES, LIABILITIES, DAMAGES, JUDGMENTS, SETTLEMENTS, FINES, PENALTIES, SANCTIONS, COSTS, AND EXPENSES (INCLUDING REASONABLE ATTORNEYS' FEES, EXPERT FEES, AND COSTS OF INVESTIGATION AND DEFENSE) ARISING OUT OF OR RELATING TO:

(a) YOUR USE OF, RELIANCE ON, OR INABILITY TO USE THE SKILLS OR ANY MODIFIED SKILL, AND ANYTHING YOU PRODUCED WITH ANY OF THEM;

(b) ANY LEGAL WORK PRODUCT, ADVICE, FILING, OR REPRESENTATION IN WHICH YOU USED THE SKILLS, INCLUDING ANY MALPRACTICE CLAIM, FEE DISPUTE, SANCTIONS PROCEEDING, BAR GRIEVANCE, OR DISCIPLINARY PROCEEDING;

(c) YOUR BREACH OF THESE TERMS, INCLUDING ANY DISTRIBUTION THAT FAILS TO SATISFY A CONDITION;

(d) ANY MODIFIED SKILL YOU MADE OR DISTRIBUTED, AND ANY CLAIM BROUGHT BY A PERSON WHO RECEIVED THE SKILLS OR A MODIFIED SKILL FROM YOU;

(e) YOUR VIOLATION OF ANY LAW, REGULATION, COURT RULE, OR RULE OF PROFESSIONAL CONDUCT; AND

(f) ANY CLAIM THAT THE SKILLS AS YOU USED OR CHANGED THEM, ANY MODIFIED SKILL OF YOURS, OR YOUR WORK PRODUCT INFRINGES OR MISAPPROPRIATES THE INTELLECTUAL PROPERTY OR OTHER RIGHTS OF ANY PERSON.

EXPRESS NEGLIGENCE. THE INDEMNITY IN THIS SECTION AND THE DISCLAIMERS AND LIABILITY LIMITS IN THE TWO SECTIONS ABOVE APPLY EVEN IF THE CLAIM, LOSS, OR LIABILITY IS ALLEGED OR FOUND TO ARISE, IN WHOLE OR IN PART, FROM THE NEGLIGENCE OF A LICENSOR PARTY — INCLUDING A LICENSOR PARTY'S OWN SOLE OR CONCURRENT NEGLIGENCE, AND INCLUDING ANY NEGLIGENT ACT OR OMISSION IN WRITING, TESTING, DOCUMENTING, OR MAINTAINING THE SKILLS. THEY DO NOT APPLY TO A LICENSOR PARTY'S GROSS NEGLIGENCE, WILLFUL MISCONDUCT, OR FRAUD.

FAIR NOTICE. YOU ACKNOWLEDGE THAT THE NO WARRANTY, NO LIABILITY, AND INDEMNIFICATION SECTIONS ARE CONSPICUOUS, THAT YOU HAVE READ THEM, AND THAT YOU UNDERSTAND YOU ARE AGREEING TO SHIFT RISK — INCLUDING RISK ARISING FROM A LICENSOR PARTY'S OWN NEGLIGENCE — IN EXCHANGE FOR RECEIVING THE SKILLS AT NO CHARGE. THIS EXCHANGE IS AN ESSENTIAL PART OF THE BARGAIN AND THE LICENSOR WOULD NOT OTHERWISE MAKE THE SKILLS AVAILABLE.

Procedure. The licensor will notify you in writing of any claim for which it seeks indemnity. You will control the defense with counsel reasonably acceptable to the licensor, except that a licensor party may participate with its own counsel at its own expense, and you may not consent to any judgment or settlement that imposes any obligation, payment, restriction, or admission of fault on a licensor party without that party's prior written consent. If you fail to assume the defense promptly, the licensor may defend itself at your expense. Your failure to receive notice does not relieve you of your obligations except to the extent you are actually and materially prejudiced by it.

Survival. This section survives the termination of your licenses.

Violations

Your license to distribute a copy never vests unless the conditions in Conditions on Distribution are satisfied as to that copy, and terminates automatically if they are not. If you stop the noncompliant distribution and come into full compliance within 32 days of first learning of the violation, your distribution license is reinstated going forward, as of the date compliance is restored. Reinstatement is prospective only, and does not retroactively authorize any distribution you made while out of compliance.

If your licenses end, the licenses of anyone who received a copy from you, and who is in compliance with these terms, continue.

Severability

Each of these terms stands on its own. If any term is held invalid, unenforceable, or preempted, it is modified to the least extent necessary to make it enforceable, or if it cannot be, it is severed — and the rest of these terms remain in full force. Nothing here waives any right the licensor has under copyright, trademark, or other law independent of these terms.

CLASS ACTION WAIVER

This section contains a class action waiver. Please read it carefully.

YOU AND THE LICENSOR EACH AGREE TO BRING ANY CLAIM OR DISPUTE ARISING OUT OF OR RELATING TO THESE TERMS, THE SKILLS, OR ANY MODIFIED SKILL SOLELY IN AN INDIVIDUAL CAPACITY. YOU AND THE LICENSOR EACH AGREE NOT TO BRING, JOIN, PARTICIPATE IN, OR SERVE AS A PLAINTIFF, CLASS MEMBER, CLASS REPRESENTATIVE, OR NAMED PARTY IN ANY CLASS, COLLECTIVE, CONSOLIDATED, REPRESENTATIVE, OR MULTI-PARTY ACTION AGAINST THE OTHER, AND EACH WAIVES ANY RIGHT TO SEEK OR RECOVER CLASSWIDE OR REPRESENTATIVE RELIEF.

NO CONSOLIDATION. YOU AND THE LICENSOR EACH AGREE NOT TO SEEK TO JOIN OR CONSOLIDATE THE CLAIMS OF MORE THAN ONE PERSON IN A SINGLE PROCEEDING WITHOUT THE WRITTEN CONSENT OF EVERY PARTY TO THAT PROCEEDING.

YOUR INDIVIDUAL CLAIMS ARE PRESERVED. THIS SECTION LIMITS ONLY THE FORM OF PROCEEDING. IT DOES NOT WAIVE, RELEASE, OR LIMIT ANY CLAIM OR REMEDY YOU MAY PURSUE INDIVIDUALLY, INCLUDING ANY REMEDY PROVIDED BY STATUTE, AND IT DOES NOT PREVENT YOU FROM BRINGING AN INDIVIDUAL ACTION IN ANY COURT OF COMPETENT JURISDICTION, INCLUDING A SMALL CLAIMS COURT.

PARTIAL UNENFORCEABILITY. IF THIS SECTION IS HELD UNENFORCEABLE AS TO ANY PARTICULAR CLAIM OR ANY PARTICULAR FORM OF RELIEF, THAT CLAIM OR REQUEST FOR RELIEF WILL BE SEVERED AND MAY PROCEED, AND THIS SECTION WILL REMAIN IN FULL FORCE AS TO EVERY OTHER CLAIM AND FORM OF RELIEF.

Construction

These terms are not to be construed against the licensor merely because the licensor drafted them. Where these terms say a requirement is a condition, it is a condition, and no rule of construction favoring covenants over conditions, or disfavoring forfeiture, should be applied to turn it into a covenant. The licensor makes the Skills available free of charge, and compliance with these conditions — attribution, notice retention, marking of changes, and passing on the same terms — is the consideration the licensor receives in place of a fee.

Governing Law

These terms are governed by the laws of the State of Texas, without regard to its conflict of laws principles. Any action arising out of or relating to these terms shall be brought exclusively in the state or federal courts located in Travis County, Texas.

Definitions

The licensor is DingDuff Inc., a Texas corporation.

The licensor parties are the licensor and its officers, directors, shareholders, employees, agents, contractors, affiliates, successors, and assigns.

The Skills are the materials described in What These Terms Cover.

A Modified Skill is a Skill you have changed, and any new work based on a Skill or substantially derived from one.

Your Own Material is material you created that is not a Skill, not a Modified Skill, and not substantially derived from a Skill.

You refers to the individual or entity agreeing to these terms.

Your organization is any legal entity, sole proprietorship, law firm, or other kind of organization that you work for or own, plus all organizations that have control over, are under the control of, or are under common control with that organization, together with that organization's personnel and contractors acting on its behalf. Control means ownership of substantially all the assets of an entity, or the power to direct its management and policies by vote, contract, or otherwise. Control can be direct or indirect.

Distribute means making a copy available to anyone outside your organization, by any means — including publishing, posting, uploading, mirroring, hosting, sending, or handing it over — and includes running the Skills for other people as described in Distribution License.

Your licenses are all the licenses granted to you for the Skills under these terms.

Use means anything you do with the Skills requiring one of your licenses.
