Mason Plugin Limited Use License 1.0
Identifier: LicenseRef-Mason-Plugin-1.0

Copyright (c) 2026 Enduring Labs, Inc. All rights reserved.

1. Covered materials

This license covers the Mason plugin files supplied by Enduring Labs, Inc.
("Enduring Labs"), including bundled skill instructions, manifests,
documentation, and assets (the "Plugin Materials"). It does not license Mason's
hosted application or backend, service APIs, customer data, or third-party
materials. Access to Mason services remains governed by your applicable Mason
agreement, account permissions, and the services' terms.

2. Installation and use

Subject to this license, Enduring Labs grants you a limited, non-exclusive,
non-transferable, non-sublicensable right to download, install, update, inspect,
and use the Plugin Materials solely to access and operate Mason through a
supported host using an authorized Mason account. This includes personal and
business use and internal deployment to your organization's authorized users.
You may make copies reasonably necessary for that installation, operation,
internal deployment, and backup. Your host and its service providers may load
and process the Plugin Materials as necessary to perform that authorized use.

3. Restrictions

Except as permitted in sections 2 and 4, required by applicable law, or separately
authorized in writing by Enduring Labs, you may not:

- Publish, redistribute, sublicense, sell, rent, or otherwise provide copies of
  the Plugin Materials to third parties, alone or as part of another package.
- Modify, adapt, translate, or create derivative works of the Plugin Materials,
  or extract and reuse the skill instructions in another plugin, prompt library,
  product, or service.
- Copy, incorporate, or adapt the Plugin Materials to develop, improve, or
  distribute a product or service that competes with Mason. This restriction
  concerns reuse of the Plugin Materials; it does not prohibit independently
  developed functionality or ordinary authorized use of Mason.
- Remove or alter copyright, licensing, ownership, or attribution notices, or
  represent the Plugin Materials as your own work or as endorsed by Enduring Labs.

4. Authorized platforms and rights under other terms

When Enduring Labs authorizes distribution through a host or directory, that
operator and its service providers may review, test, scan, host, cache, package,
display, and deliver the Plugin Materials and updates as necessary to list,
distribute, secure, and operate the Mason plugin for authorized users. This
permission does not authorize distributing a competing or rebranded plugin.

This license does not revoke or narrow rights that Enduring Labs grants under
applicable hosting, directory, or developer terms. For example, publishing a
public GitHub repository grants viewing and forking rights under GitHub's terms,
and OpenAI's App Developer Terms grant rights in content returned as API
responses. Those separately granted rights govern to the extent of a conflict;
this license supplies no additional right to reuse or redistribute the Plugin
Materials outside the permissions stated here. Public visibility is not a
general license to reuse the Plugin Materials. Rights that cannot lawfully be
excluded remain unaffected.

5. Ownership, branding, and task results

Enduring Labs retains ownership of the Plugin Materials. No trademark rights
are granted beyond displaying the included Mason name and logo with the
unmodified plugin and its authorized listings to identify the service and
publisher. No separate reuse, rebranding, or implied endorsement is permitted.
Ordinary business data and task results are outside this license and remain
subject to applicable agreements and platform terms. A reproduction of Plugin
Materials does not become unrestricted merely by appearing in a task result;
any separately granted rights under section 4 still apply.

6. Termination

The permissions granted by this license terminate if you materially violate
its terms. On termination, stop using and delete the Plugin Materials and copies
under your control, except as required by applicable law or separately governing
platform terms. Termination does not revoke rights independently granted under
those terms. Sections 3 through 8 survive termination to the extent applicable.

7. Disclaimer and liability

TO THE EXTENT PERMITTED BY APPLICABLE LAW AND SUBJECT TO ANY SEPARATE WRITTEN
AGREEMENT WITH ENDURING LABS, THE PLUGIN MATERIALS ARE PROVIDED "AS IS", WITHOUT
WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY,
FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. ENDURING LABS IS NOT
LIABLE FOR DAMAGES ARISING FROM THE PLUGIN MATERIALS UNDER THIS LICENSE TO THE
EXTENT SUCH LIABILITY MAY LAWFULLY BE EXCLUDED. NON-EXCLUDABLE RIGHTS REMAIN
UNAFFECTED.

8. Other permissions

Rights not expressly granted are reserved. Requests for separate written
permission may be sent to hello@thisismason.com.
