Preamble
Preamble
The GNU Affero General Public License is a free, copyleft license for software and other kinds of works, specifically designed to ensure cooperation with the community in the case of network server software.
The GNU Affero General Public License is a free, copyleft license for software
The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, our General Public Licenses are intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users. and other kinds of works, specifically designed to ensure cooperation with
the community in the case of network server software.
When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things.
The licenses for most software and other practical works are designed to take

By contrast, our General
Public Licenses are intended to guarantee your freedom to share and change
A secondary benefit of defending all users' freedom is that improvements made in alternate versions of the program, if they receive widespread use, become available for other developers to incorporate. Many developers of free software are heartened and encouraged by the resulting cooperation. However, in the case of software used on network servers, this result may fail to come about. The GNU General Public License permits making a modified version and letting the public access it on a server without ever releasing its source code to the public. all versions of a program--to make sure it remains free software for all its
users.
The GNU Affero General Public License is designed specifically to ensure that, in such cases, the modified source code becomes available to the community. It requires the operator of a network server to provide the source code of the modified version running there to the users of that server. Therefore, public use of a modified version, on a publicly accessible server, gives the public access to the source code of the modified version.
When we speak of free software, we are referring to freedom, not price. Our
An older license, called the Affero General Public License and published by Affero, was designed to accomplish similar goals. This is a different license, not a version of the Affero GPL, but Affero has released a new version of the Affero GPL which permits relicensing under this license. General Public Licenses are designed to make sure that you have the freedom

steps: (1) assert copyright on the software, and (2) offer you this License
"This License" refers to version 3 of the GNU Affero General Public License. which gives you legal permission to copy, distribute and/or modify the software.
"Copyright" also means copyright-like laws that apply to other kinds of works, such as semiconductor masks. A secondary benefit of defending all users' freedom is that improvements made
in alternate versions of the program, if they receive widespread use, become

The GNU General Public License permits making a modified version and letting
A "covered work" means either the unmodified Program or a work based on the Program. the public access it on a server without ever releasing its source code to
the public.
To "propagate" a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well.
The GNU Affero General Public License is designed specifically to ensure that,
To "convey" a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying. in such cases, the modified source code becomes available to the community.
It requires the operator of a network server to provide the source code of
An interactive user interface displays "Appropriate Legal Notices" to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion. the modified version running there to the users of that server. Therefore,

The "source code" for a work means the preferred form of the work for making modifications to it. "Object code" means any non-source form of a work.
An older license, called the Affero General Public License and published by
A "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language. Affero, was designed to accomplish similar goals. This is a different license,
not a version of the Affero GPL, but Affero has released a new version of
The "System Libraries" of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A "Major Component", in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it. the Affero GPL which permits relicensing under this license.
The "Corresponding Source" for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those The precise terms and conditions for copying, distribution and modification

2. Basic Permissions. "This License" refers to version 3 of the GNU Affero General Public License.
All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law.
"Copyright" also means copyright-like laws that apply to other kinds of works,
You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you. such as semiconductor masks.
Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary. "The Program" refers to any copyrightable work licensed under this License.
Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals

No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures.
To "modify" a work means to copy from or adapt all or part of the work in
When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures. a fashion requiring copyright permission, other than the making of an exact
copy. The resulting work is called a "modified version" of the earlier work
4. Conveying Verbatim Copies. or a work "based on" the earlier work.
You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program.
A "covered work" means either the unmodified Program or a work based on the

5. Conveying Modified Source Versions. To "propagate" a work means to do anything with it that, without permission,
You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions: would make you directly or secondarily liable for infringement under applicable
copyright law, except executing it on a computer or modifying a private copy.

c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it. To "convey" a work means any kind of propagation that enables other parties
to make or receive copies. Mere interaction with a user through a computer

A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an "aggregate" if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate. An interactive user interface displays "Appropriate Legal Notices" to the
extent that it includes a convenient and prominently visible feature that

If the interface presents a list of user commands
or options, such as a menu, a prominent item in the list meets this criterion.
b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge.
1. Source Code.
c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b.
The "source code" for a work means the preferred form of the work for making
d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements. modifications to it. "Object code" means any non-source form of a work.
e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d. A "Standard Interface" means an interface that either is an official standard
defined by a recognized standards body, or, in the case of interfaces specified
A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work. for a particular programming language, one that is widely used among developers
working in that language.
A "User Product" is either (1) a "consumer product", which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, "normally used" refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product.
The "System Libraries" of an executable work include anything, other than
"Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made. the work as a whole, that (a) is included in the normal form of packaging
a Major Component, but which is not part of that Major Component, and (b)
If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM). serves only to enable use of the work with that Major Component, or to implement
a Standard Interface for which an implementation is available to the public
The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network. in source code form. A "Major Component", in this context, means a major essential
component (kernel, window system, and so on) of the specific operating system
Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying. (if any) on which the executable work runs, or a compiler used to produce
the work, or an object code interpreter used to run it.
7. Additional Terms.
"Additional permissions" are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions. The "Corresponding Source" for a work in object code form means all the source
code needed to generate, install, and (for an executable work) run the object
When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission. code and to modify the work, including scripts to control those activities.
However, it does not include the work's System Libraries, or general-purpose
Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms: tools or generally available free programs which are used unmodified in performing
those activities but which are not part of the work. For example, Corresponding
a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or Source includes interface definition files associated with source files for
the work, and the source code for shared libraries and dynamically linked
b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or subprograms that the work is specifically designed to require, such as by
intimate data communication or control flow between those
c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or
subprograms and other parts of the work.
d) Limiting the use for publicity purposes of names of licensors or authors of the material; or
The Corresponding Source need not include anything that users can regenerate
e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or automatically from other parts of the Corresponding Source.
f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors. The Corresponding Source for a work in source code form is that same work.
All other non-permissive additional terms are considered "further restrictions" within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying. 2. Basic Permissions.
If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms. All rights granted under this License are granted for the term of copyright
on the Program, and are irrevocable provided the stated conditions are met.
Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way. This License explicitly affirms your unlimited permission to run the unmodified
Program. The output from running a covered work is covered by this License
8. Termination. only if the output, given its content, constitutes a covered work. This License
acknowledges your rights of fair use or other equivalent, as provided by copyright
You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11). law.
However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation. You may make, run and propagate covered works that you do not convey, without
conditions so long as your license otherwise remains in force. You may convey
Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice. covered works to others for the sole purpose of having them make modifications
exclusively for you, or provide you with facilities for running those works,
Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10. provided that you comply with the terms of this License in conveying all material
for which you do not control copyright. Those thus making or running the covered
9. Acceptance Not Required for Having Copies. works for you must do so exclusively on your behalf, under your direction
and control, on terms that prohibit them from making any copies of your copyrighted
You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so. material outside their relationship with you.
10. Automatic Licensing of Downstream Recipients. Conveying under any other circumstances is permitted solely under the conditions
stated below. Sublicensing is not allowed; section 10 makes it unnecessary.
Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License.
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
An "entity transaction" is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts.
No covered work shall be deemed part of an effective technological measure
You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it. under any applicable law fulfilling obligations under article 11 of the WIPO
copyright treaty adopted on 20 December 1996, or similar laws prohibiting
11. Patents. or restricting circumvention of such measures.
A "contributor" is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's "contributor version". When you convey a covered work, you waive any legal power to forbid circumvention
of technological measures to the extent such circumvention is effected by
A contributor's "essential patent claims" are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, "control" includes the right to grant patent sublicenses in a manner consistent with the requirements of this License. exercising rights under this License with respect to the covered work, and
you disclaim any intention to limit operation or modification of the work
Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version. as a means of enforcing, against the work's users, your or third parties'
legal rights to forbid circumvention of technological measures.
In the following three paragraphs, a "patent license" is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To "grant" such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party.
4. Conveying Verbatim Copies.
If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent
license to downstream recipients. "Knowingly relying" means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid. You may convey verbatim copies of the Program's source code as you receive
it, in any medium, provided that you conspicuously and appropriately publish
If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it. on each copy an appropriate copyright notice; keep intact all notices stating
that this License and any non-permissive terms added in accord with section
A patent license is "discriminatory" if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007. 7 apply to the code; keep intact all notices of the absence of any warranty;
and give all recipients a copy of this License along with the Program.
Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law.
You may charge any price or no price for each copy that you convey, and you
12. No Surrender of Others' Freedom. may offer support or warranty protection for a fee.
If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may 5.

not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program.
You may convey a work based on the Program, or the modifications to produce

4, provided that you also meet all of these conditions:
Notwithstanding any other provision of this License, if you modify the Program, your modified version must prominently offer all users interacting with it remotely through a computer network (if your version supports such interaction) an opportunity to receive the Corresponding Source of your version by providing access to the Corresponding Source from a network server at no charge, through some standard or customary means of facilitating copying of software.

a) The work must carry prominent notices stating that you modified it, and
Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU General Public License into a single combined work, and to convey the resulting work.

If the Program does not specify a version number of the GNU Affero General Public License, you may choose any version ever published by the Free Software Foundation. c) You must license the entire work, as a whole, under this License to anyone

How to Apply These Terms to Your New Programs 6. Conveying Non-Source Forms.
If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. You may convey a covered work in object code form under the terms of sections
4 and 5, provided that you also convey the machine-readable Corresponding
To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively state the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Source under the terms of this License, in one of these ways:
python_jms_clienter a) Convey the object code in, or embodied in, a physical product (including
Copyright (C) 2026 huangsijun17 a physical distribution medium), accompanied by the Corresponding Source fixed
on a durable physical medium customarily used for software interchange.
This program is free software: you can redistribute it and/or modify it under the terms of the GNU Affero General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.
b) Convey the object code in, or embodied in, a physical product (including
This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU Affero General Public License for more details. a physical distribution medium), accompanied by a written offer, valid for
at least three years and valid for as long as you offer spare parts or customer
You should have received a copy of the GNU Affero General Public License along with this program. If not, see <http://www.gnu.org/licenses/>. support for that product model, to give anyone who possesses the object code
either (1) a copy of the Corresponding Source for all the software in the
product that is covered by this License, on a durable physical medium customarily
used for software interchange, for a price no more than your reasonable cost
of physically performing this conveying of source, or (2) access to copy the
Corresponding Source from a network server at no charge.
c) Convey individual copies of the object code with a copy of the written
offer to provide the Corresponding Source. This alternative is allowed only
occasionally and noncommercially, and only if you received the object code
with such an offer, in accord with subsection 6b.
d) Convey the object code by offering access from a designated place (gratis
or for a charge), and offer equivalent access to the Corresponding Source
in the same way through the same place at no further charge. You need not
require recipients to copy the Corresponding Source along with the object
code. If the place to copy the object code is a network server, the Corresponding
Source may be on a different server (operated by you or a third party) that
supports equivalent copying facilities, provided you maintain clear directions
next to the object code saying where to find the Corresponding Source. Regardless
of what server hosts the Corresponding Source, you remain obligated to ensure
that it is available for as long as needed to satisfy these requirements.
e) Convey the object code using peer-to-peer transmission, provided you inform
other peers where the object code and Corresponding Source of the work are
being offered to the general public at no charge under subsection 6d.
A separable portion of the object code, whose source code is excluded from
the Corresponding Source as a System Library, need not be included in conveying
the object code work.
A "User Product" is either (1) a "consumer product", which means any tangible
personal property which is normally used for personal, family, or household
purposes, or (2) anything designed or sold for incorporation into a dwelling.
In determining whether a product is a consumer product, doubtful cases shall
be resolved in favor of coverage. For a particular product received by a particular
user, "normally used" refers to a typical or common use of that class of product,
regardless of the status of the particular user or of the way in which the
particular user actually uses, or expects or is expected to use, the product.
A product is a consumer product regardless of whether the product has substantial
commercial, industrial or non-consumer uses, unless such uses represent the
only significant mode of use of the product.
"Installation Information" for a User Product means any methods, procedures,
authorization keys, or other information required to install and execute modified
versions of a covered work in that User Product from a modified version of
its Corresponding Source. The information must suffice to ensure that the
continued functioning of the modified object code is in no case prevented
or interfered with solely because modification has been made.
If you convey an object code work under this section in, or with, or specifically
for use in, a User Product, and the conveying occurs as part of a transaction
in which the right of possession and use of the User Product is transferred
to the recipient in perpetuity or for a fixed term (regardless of how the
transaction is characterized), the Corresponding Source conveyed under this
section must be accompanied by the Installation Information. But this requirement
does not apply if neither you nor any third party retains the ability to install
modified object code on the User Product (for example, the work has been installed
in ROM).
The requirement to provide Installation Information does not include a requirement
to continue to provide support service, warranty, or updates for a work that
has been modified or installed by the recipient, or for the User Product in
which it has been modified or installed. Access to a network may be denied
when the modification itself materially and adversely affects the operation
of the network or violates the rules and protocols for communication across
the network.
Corresponding Source conveyed, and Installation Information provided, in accord
with this section must be in a format that is publicly documented (and with
an implementation available to the public in source code form), and must require
no special password or key for unpacking, reading or copying.
7. Additional Terms.
"Additional permissions" are terms that supplement the terms of this License
by making exceptions from one or more of its conditions. Additional permissions
that are applicable to the entire Program shall be treated as though they
were included in this License, to the extent that they are valid under applicable
law. If additional permissions apply only to part of the Program, that part
may be used separately under those permissions, but the entire Program remains
governed by this License without regard to the additional permissions.
When you convey a copy of a covered work, you may at your option remove any
additional permissions from that copy, or from any part of it. (Additional
permissions may be written to require their own removal in certain cases when
you modify the work.) You may place additional permissions on material, added
by you to a covered work, for which you have or can give appropriate copyright
permission.
Notwithstanding any other provision of this License, for material you add
to a covered work, you may (if authorized by the copyright holders of that
material) supplement the terms of this License with terms:
a) Disclaiming warranty or limiting liability differently from the terms of
sections 15 and 16 of this License; or
b) Requiring preservation of specified reasonable legal notices or author
attributions in that material or in the Appropriate Legal Notices displayed
by works containing it; or
c) Prohibiting misrepresentation of the origin of that material, or requiring
that modified versions of such material be marked in reasonable ways as different
from the original version; or
d) Limiting the use for publicity purposes of names of licensors or authors
of the material; or
e) Declining to grant rights under trademark law for use of some trade names,
trademarks, or service marks; or
f) Requiring indemnification of licensors and authors of that material by
anyone who conveys the material (or modified versions of it) with contractual
assumptions of liability to the recipient, for any liability that these contractual
assumptions directly impose on those licensors and authors.
All other non-permissive additional terms are considered "further restrictions"
within the meaning of section 10. If the Program as you received it, or any
part of it, contains a notice stating that it is governed by this License
along with a term that is a further restriction, you may remove that term.
If a license document contains a further restriction but permits relicensing
or conveying under this License, you may add to a covered work material governed
by the terms of that license document, provided that the further restriction
does not survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you must place,
in the relevant source files, a statement of the additional terms that apply
to those files, or a notice indicating where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the form
of a separately written license, or stated as exceptions; the above requirements
apply either way.
8. Termination.
You may not propagate or modify a covered work except as expressly provided
under this License. Any attempt otherwise to propagate or modify it is void,
and will automatically terminate your rights under this License (including
any patent licenses granted under the third paragraph of section 11).
However, if you cease all violation of this License, then your license from
a particular copyright holder is reinstated (a) provisionally, unless and
until the copyright holder explicitly and finally terminates your license,
and (b) permanently, if the copyright holder fails to notify you of the violation
by some reasonable means prior to 60 days after the cessation.
Moreover, your license from a particular copyright holder is reinstated permanently
if the copyright holder notifies you of the violation by some reasonable means,
this is the first time you have received notice of violation of this License
(for any work) from that copyright holder, and you cure the violation prior
to 30 days after your receipt of the notice.
Termination of your rights under this section does not terminate the licenses
of parties who have received copies or rights from you under this License.
If your rights have been terminated and not permanently reinstated, you do
not qualify to receive new licenses for the same material under section 10.
9. Acceptance Not Required for Having Copies.
You are not required to accept this License in order to receive or run a copy
of the Program. Ancillary propagation of a covered work occurring solely as
a consequence of using peer-to-peer transmission to receive a copy likewise
does not require acceptance. However, nothing other than this License grants
you permission to propagate or modify any covered work. These actions infringe
copyright if you do not accept this License. Therefore, by modifying or propagating
a covered work, you indicate your acceptance of this License to do so.
10. Automatic Licensing of Downstream Recipients.
Each time you convey a covered work, the recipient automatically receives
a license from the original licensors, to run, modify and propagate that work,
subject to this License. You are not responsible for enforcing compliance
by third parties with this License.
An "entity transaction" is a transaction transferring control of an organization,
or substantially all assets of one, or subdividing an organization, or merging
organizations. If propagation of a covered work results from an entity transaction,
each party to that transaction who receives a copy of the work also receives
whatever licenses to the work the party's predecessor in interest had or could
give under the previous paragraph, plus a right to possession of the Corresponding
Source of the work from the predecessor in interest, if the predecessor has
it or can get it with reasonable efforts.
You may not impose any further restrictions on the exercise of the rights
granted or affirmed under this License. For example, you may not impose a
license fee, royalty, or other charge for exercise of rights granted under
this License, and you may not initiate litigation (including a cross-claim
or counterclaim in a lawsuit) alleging that any patent claim is infringed
by making, using, selling, offering for sale, or importing the Program or
any portion of it.
11. Patents.
A "contributor" is a copyright holder who authorizes use under this License
of the Program or a work on which the Program is based. The work thus licensed
is called the contributor's "contributor version".
A contributor's "essential patent claims" are all patent claims owned or controlled
by the contributor, whether already acquired or hereafter acquired, that would
be infringed by some manner, permitted by this License, of making, using,
or selling its contributor version, but do not include claims that would be
infringed only as a consequence of further modification of the contributor
version. For purposes of this definition, "control" includes the right to
grant patent sublicenses in a manner consistent with the requirements of this
License.
Each contributor grants you a non-exclusive, worldwide, royalty-free patent
license under the contributor's essential patent claims, to make, use, sell,
offer for sale, import and otherwise run, modify and propagate the contents
of its contributor version.
In the following three paragraphs, a "patent license" is any express agreement
or commitment, however denominated, not to enforce a patent (such as an express
permission to practice a patent or covenant not to s ue for patent infringement).
To "grant" such a patent license to a party means to make such an agreement
or commitment not to enforce a patent against the party.
If you convey a covered work, knowingly relying on a patent license, and the
Corresponding Source of the work is not available for anyone to copy, free
of charge and under the terms of this License, through a publicly available
network server or other readily accessible means, then you must either (1)
cause the Corresponding Source to be so available, or (2) arrange to deprive
yourself of the benefit of the patent license for this particular work, or
(3) arrange, in a manner consistent with the requirements of this License,
to extend the patent
license to downstream recipients. "Knowingly relying" means you have actual
knowledge that, but for the patent license, your conveying the covered work
in a country, or your recipient's use of the covered work in a country, would
infringe one or more identifiable patents in that country that you have reason
to believe are valid.
If, pursuant to or in connection with a single transaction or arrangement,
you convey, or propagate by procuring conveyance of, a covered work, and grant
a patent license to some of the parties receiving the covered work authorizing
them to use, propagate, modify or convey a specific copy of the covered work,
then the patent license you grant is automatically extended to all recipients
of the covered work and works based on it.
A patent license is "discriminatory" if it does not include within the scope
of its coverage, prohibits the exercise of, or is conditioned on the non-exercise
of one or more of the rights that are specifically granted under this License.
You may not convey a covered work if you are a party to an arrangement with
a third party that is in the business of distributing software, under which
you make payment to the third party based on the extent of your activity of
conveying the work, and under which the third party grants, to any of the
parties who would receive the covered work from you, a discriminatory patent
license (a) in connection with copies of the covered work conveyed by you
(or copies made from those copies), or (b) primarily for and in connection
with specific products or compilations that contain the covered work, unless
you entered into that arrangement, or that patent license was granted, prior
to 28 March 2007.
Nothing in this License shall be construed as excluding or limiting any implied
license or other defenses to infringement that may otherwise be available
to you under applicable patent law.
12. No Surrender of Others' Freedom.
If conditions are imposed on you (whether by court order, agreement or otherwise)
that contradict the conditions of this License, they do not excuse you from
the conditions of this License. If you cannot convey a covered work so as
to satisfy simultaneously your obligations under this License and any other
pertinent obligations, then as a consequence you may
not convey it at all. For example, if you agree to terms that obligate you
to collect a royalty for further conveying from those to whom you convey the
Program, the only way you could satisfy both those terms and this License
would be to refrain entirely from conveying the Program.
13. Remote Network Interaction; Use with the GNU General Public License.
Notwithstanding any other provision of this License, if you modify the Program,
your modified version must prominently offer all users interacting with it
remotely through a computer network (if your version supports such interaction)
an opportunity to receive the Corresponding Source of your version by providing
access to the Corresponding Source from a network server at no charge, through
some standard or customary means of facilitating copying of software. This
Corresponding Source shall include the Corresponding Source for any work covered
by version 3 of the GNU General Public License that is incorporated pursuant
to the following paragraph.
Notwithstanding any other provision of this License, you have permission to
link or combine any covered work with a work licensed under version 3 of the
GNU General Public License into a single combined work, and to convey the
resulting work. The terms of this License will continue to apply to the part
which is the covered work, but the work with which it is combined will remain
governed by version 3 of the GNU General Public License.
14. Revised Versions of this License.
The Free Software Foundation may publish revised and/or new versions of the
GNU Affero General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to address
new problems or concerns.
Each version is given a distinguishing version number. If the Program specifies
that a certain numbered version of the GNU Affero General Public License "or
any later version" applies to it, you have the option of following the terms
and conditions either of that numbered version or of any later version published
by the Free Software Foundation. If the Program does not specify a version
number of the GNU Affero General Public License, you may choose any version
ever published by the Free Software Foundation.
If the Program specifies that a proxy can decide which future versions of
the GNU Affero General Public License can be used, that proxy's public statement
of acceptance of a version permanently authorizes you to choose that version
for the Program.
Later license versions may give you additional or different permissions. However,
no additional obligations are imposed on any author or copyright holder as
a result of your choosing to follow a later version.
15. Disclaimer of Warranty.
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE
LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES
OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM
PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
CORRECTION.
16. Limitation of Liability.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL
ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM
AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO
USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE
PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
17. Interpretation of Sections 15 and 16.
If the disclaimer of warranty and limitation of liability provided above cannot
be given local legal effect according to their terms, reviewing courts shall
apply local law that most closely approximates an absolute waiver of all civil
liability in connection with the Program, unless a warranty or assumption
of liability accompanies a copy of the Program in return for a fee. END OF
TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest possible
use to the public, the best way to achieve this is to make it free software
which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest to attach
them to the start of each source file to most effectively state the exclusion
of warranty; and each file should have at least the "copyright" line and a
pointer to where the full notice is found.

If your software can interact with users remotely through a computer network, you should also make sure that it provides a way for users to get its source. For example, if your program is a web application, its interface could display a "Source" link that leads users to an archive of the code. There are many ways you could offer source, and different solutions will be better for different programs; see section 13 for the specific requirements.

# python_jms_clienter # python_jms_clienter
一个面向 JumpServer 的 Python 客户端，支持以下三种使用方式：
- 作为 Python 模块导入
- 作为 CLI 命令执行（可直接输出 JSON）
- 作为 TUI 交互程序执行（服务器和用户名均通过选择，不需要手工输入）
---
## 中文说明
### 1) 项目定位
`python_jms_clienter` 是一个**第三方客户端工具**，用于通过 JumpServer OpenAPI 获取连接 token，支持数据库（不限 MySQL）和 SSH 主机场景。
### 2) 与 JumpServer 项目的关系
请注意以下边界：
1. 本项目**不是 JumpServer 官方项目**，也不是 JumpServer 服务端的插件。
2. 本项目仅调用 JumpServer 暴露的 OpenAPI 接口，不包含 JumpServer 服务端实现代码。
3. 本项目需要你已经部署并可访问 JumpServer 实例，且有可用的 Access Key（`key_id` / `key_secret`）。
4. 本项目 API 字段与流程参考仓库内 `doc/api/less.json`（JumpServer OpenAPI 导出），不同 JumpServer 版本可能存在差异。
5. `JumpServer` 名称与商标归原项目及其权利方所有，本项目仅做兼容调用。
### 3) 当前实现的能力
- 列出可用服务器（支持数据库与 SSH）
- 按服务器列出可选用户名
- 默认输出“可连接账号”对应用户名（会做 token 探测）
- 可用 `--raw` 查看 JumpServer `username-suggestions` 原始结果
- 基于 `asset + account` 申请连接 token
- `get-token` 默认输出精简字段（自动识别 SSH/数据库连接方式）：
- `token_username = token.id`
- `token_password = token.value`
### 4) 使用到的关键接口
- `GET /api/v1/assets/assets/suggestions/`
- `GET /api/v1/assets/databases/suggestions/`
- `GET /api/v1/assets/hosts/suggestions/`（以及设备/网关等 suggestions 端点）
- `POST /api/v1/accounts/accounts/username-suggestions/`
- `POST /api/v1/authentication/connection-token/`
鉴权方式：`Authorization: Signature ...`（HMAC-SHA256）
### 5) 安装
先安装依赖：
```bash
pip install -r requirements.txt
```
开发模式安装（会注册 `jms-client` 命令）：
```bash
pip install -e .
```
### 6) 环境变量
```bash
export JMS_BASE_URL="https://jumpserver.example.com"
export JMS_KEY_ID="your-access-key-id"
export JMS_KEY_SECRET="your-access-key-secret"
export JMS_ORG_ID="00000000-0000-0000-0000-000000000002" # 可选
export JMS_VERIFY_SSL="true" # 可选，false 表示跳过证书校验
export JMS_TIMEOUT="15" # 可选，单位秒
export JMS_DEBUG="true" # 可选，开启调试日志
export JMS_LOG_FILE="./jms-client.debug.log" # 可选，写入日志文件
```
### 7) CLI 用法
无子命令时默认进入 TUI：
```bash
jms-client
```
也可以通过项目根目录入口执行（`main.py` 会提供 TUI/CLI 模式选择）：
```bash
python main.py
```
直接指定模式：
```bash
python main.py tui --base-url https://jumpserver.example.com --key-id <id> --key-secret <secret>
python main.py tui
python main.py cli list-servers
python main.py tui --debug --log-file ./jms-debug.log
python main.py debug tui
python main.py debug cli list-servers
```
列服务器：
```bash
jms-client list-servers --type mysql --category database --limit 200
jms-client list-servers --protocols ssh --category "" --type "" --limit 200
```
按服务器 ID 列用户名：
```bash
jms-client list-usernames --asset-id 15d0eccb-e3dd-426f-a117-43e44520a4ac
```
按服务器名列用户名（默认仅可连接用户名）：
```bash
jms-client list-usernames --asset-name UAT-EMQX-Mysql
```
查看原始 suggestions（不做可连接性探测）：
```bash
jms-client list-usernames --asset-name UAT-EMQX-Mysql --raw
```
获取 token（指定服务器 ID + 用户名）：
```bash
jms-client get-token \
--asset-id 15d0eccb-e3dd-426f-a117-43e44520a4ac \
--account root-readonly \
--connect-method db_guide
```
说明：`get-token` 默认返回精简 token 字段；如需完整原始 token，增加 `--full-token`。
说明：若不指定 `--connect-method`，CLI 会自动识别：
- SSH 主机优先 `ssh_guide + ssh`
- 数据库资产优先 `db_guide + <db protocol>`
获取 token（按服务器名自动解析）：
```bash
jms-client get-token --asset-name mysql-prod-a --account root-readonly
```
开启调试日志（建议排障时使用）：
```bash
jms-client --debug --log-file ./jms-debug.log get-token --asset-id <id> --account <account>
```
说明：调试日志会自动对敏感字段（例如 `key-secret`、`Authorization`、token 值）做脱敏处理。
CLI 所有子命令均返回 JSON，方便脚本直接消费。
### 8) TUI 用法
TUI 中：
- 第一步选择服务器（数据库 + SSH）
- 第二步选择账号（仅展示该机器存在且当前用户可连接的账号）
- 第三步申请 token 并显示精简 JSON 结果（字段与 CLI `get-token` 默认输出一致）
- 如果未提供 `base-url / key-id / key-secret`（参数或环境变量），启动时会先友好提示输入（`key-secret` 为隐藏输入）
按键：
- `Up/Down` 移动
- `PgUp/PgDn` 翻页
- `p/n` 翻页（终端不识别 `PgUp/PgDn` 时可用）
- `Space/b` 翻页（`Space` 下一页，`b` 上一页）
- `j/k` 移动（Vim 风格）
- `/` 搜索（输入关键字过滤当前列表）
- 输入后会自动远程补拉匹配服务器（不仅是本地已加载列表）
- `c` 清除搜索过滤
- `Enter` 选择
- `q` / `Esc` 退出
### 9) 模块导入用法
推荐使用环境变量方式（避免在代码中写死密钥）：
```python
from python_jms_clienter import JMSClient
client = JMSClient.from_env(base_url="https://jumpserver.example.com")
# 也可完全从环境变量读取（包含 JMS_BASE_URL）:
# client = JMSClient.from_env()
# 开启调试日志:
# client = JMSClient.from_env(debug=True, log_file="./jms-debug.log")
servers = client.list_servers(asset_type="mysql", category="database")
ssh_servers = client.list_servers(protocols="ssh", category=None, asset_type=None)
print(servers)
print(ssh_servers)
asset_id = servers[0]["id"]
usernames = client.list_usernames(asset_id)
print(usernames)
token = client.get_connection_token(asset_id=asset_id, account=usernames[0])
print(token)
mysql_credentials = {
"username": token["id"],
"password": token["value"],
}
print(mysql_credentials)
```
如果你仍然希望显式传参，也支持：
```python
client = JMSClient(
base_url="https://jumpserver.example.com",
key_id="your-access-key-id",
key_secret="your-access-key-secret",
)
```
### 10) 安全与合规建议
- 不要把 `key_secret` 写入代码仓库，优先使用环境变量或密钥管理系统。
- 生产环境不要使用 `--insecure` / `JMS_VERIFY_SSL=false`。
- 建议为此客户端申请最小权限 API Key，仅授予必要资源范围。

# 使用准则概览
## 三省六部·流程（中书省制诏→门下省封驳→御批→尚书省承旨）
- 中书省制诏（起草/Plan）：在输出任何 to-do/方案前，必须先明示“中书省臣等开始为官家制诏：<任务简述>”。
- 门下省封驳（审议/Approve）：涉及代码或文档改动时，先在聊天中给出拟改内容（关键片段或 git apply 补丁）供官家审阅；供官家审阅前先明示"门下省臣等请示官家"，按反馈修订后再请示。
- 御批（评议）：官家同意执行时回复“准奏”。
- 尚书省承旨（执行）：收到“准奏”后，执行前必须先明示“尚书省臣等接旨”，再实际落盘修改/运行命令；修改后在 work.md 记账并提供撤回方式。
## 三省六部·强制扮演（门禁）
- 目标：确保对话按“中书省→门下省→御批→尚书省”推进，并用固定口令标记阶段，降低误执行风险。
- 固定口令与触发：
- 中书省制诏：当需要输出计划/To-do/方案时，必须以“中书省臣等开始为官家制诏：<任务简述>”开场，再给出编号步骤。
- 门下省封驳：当涉及代码/文档改动或需要执行动作（如运行命令/调用工具/落盘修改）时，必须先以“门下省臣等请示官家”开场，并贴出拟改关键片段/补丁、影响范围与撤回方式。

MCP Rules (MCP 调用规则)
目标
MCP 服务（Sequential Thinking、Context7、Serena）的选择与调用规范，控制查询粒度、速率与输出格式，保证可追溯与安全。
全局策略
工具选择：根据任务意图选择最匹配的 MCP 服务；避免无意义并发调用。
结果可靠性：默认返回精简要点 + 必要引用来源；标注时间与局限。
单轮单工具：每轮对话最多调用 1 种外部服务；确需多种时串行并说明理由。
最小必要：收敛查询范围（tokens/结果数/时间窗/关键词），避免过度抓取与噪声。
可追溯性：统一在答复末尾追加“工具调用简报”（工具、输入摘要、参数、时间、来源/重试）。
安全合规：默认离线优先；外呼须遵守 robots/ToS 与隐私要求，必要时先征得授权。
降级优先：失败按“失败与降级”执行，无法外呼时提供本地保守答案并标注不确定性。
冲突处理：遵循“冲突与优先级”的顺序，出现冲突时采取更保守策略。
速率与并发限制
速率限制：若收到 429/限流提示，退避 20 秒，降低结果数/范围；必要时切换备选服务。
安全与权限边界
隐私与安全：不上传敏感信息；遵循只读网络访问；遵守网站 robots 与 ToS。
失败与降级
失败回退：首选服务失败时，按优先级尝试替代；不可用时给出明确降级说明。
Sequential Thinking（规划分解）
触发：分解复杂问题、规划步骤、生成执行计划、评估方案。
输入：简要问题、目标、约束；限制步骤数与深度。
输出：仅产出可执行计划与里程碑，不暴露中间推理细节。
约束：步骤上限 6-10；每步一句话；可附工具或数据依赖的占位符。
Context7（技术文档知识聚合）
触发：查询 SDK/API/框架官方文档、快速知识提要、参数示例片段。
流程：先 resolve-library-id；确认最相关库；再 get-library-docs。
主题与查询：提供 topic/关键词聚焦；tokens 默认 5000，按需下调以避免冗长（示例 topic：hooks、routing、auth）。
筛选：多库匹配时优先信任度高与覆盖度高者；歧义时请求澄清或说明选择理由。
输出：精炼答案 + 引用文档段落链接或出处标识；标注库 ID/版本；给出关键片段摘要与定位（标题/段落/路径）；避免大段复制。
限制：网络受限或未授权不调用；遵守许可与引用规范。
失败与回退：无法 resolve 或无结果时，请求澄清或基于本地经验给出保守答案并标注不确定性。
无 Key 策略：可直接调用；若限流则提示并降级到 DuckDuckGo（优先官方站点）。
Serena（代码语义检索/符号级编辑)
- 用途：提供基于语言服务器（LSP）的符号级检索与代码编辑能力，帮助在大型代码库中高效定位、理解并修改代码。
- 触发：需要按符号/语义查找、跨文件引用分析、重构迁移、在指定符号前后插入或替换实现等场景。
- 流程：项目激活与索引 → 精准检索符号/引用 → 验证上下文 → 执行插入/替换 → 汇总变更与理由。
- 常用工具：
- find_symbol / find_referencing_symbols / get_symbols_overview
- insert_before_symbol / insert_after_symbol / replace_symbol_body
- search_for_pattern / find_file / read_file / create_text_file / write_file
- 使用策略：优先小范围、精准操作；单轮单工具；输出需带符号/文件定位与变更原因，便于追溯。
- 示例范式：
- “定位 Controller 方法并前置校验”：find_symbol → insert_before_symbol
- “统计实体引用并逐点修订”：find_referencing_symbols → replace_symbol_body 或 replace_regex
服务清单与用途
- Sequential Thinking：规划与分解复杂任务，形成可执行计划与里程碑。
- Context7：检索并引用官方文档/API，用于库/框架/版本差异与配置问题。
- DuckDuckGo：获取最新网页信息、官方链接与新闻/公告来源聚合。
- Serena：代码语义检索、符号级编辑、引用分析
服务选择与调用
- 意图判定：规划/分解 → Sequential；文档/API → Context7；最新信息 → DuckDuckGo。
- 前置检查：网络与权限、敏感信息、是否可离线完成、范围是否最小必要。
- 单轮单工具：按“全局策略”执行；确需多种，串行并说明理由与预期产出。
- 调用流程：
- 设定目标与范围（关键词/库ID/topic/tokens/结果数/时间窗）。
- 执行调用（遵守速率限制与安全边界）。
- 失败回退（按“失败与降级”）。
- 输出简报（来源/参数/时间/重试），确保可追溯。
- 选择示例：
- React Hook 用法 → Context7；最新安全公告 → DuckDuckGo；多文件重构计划 → Sequential Thinking。
- 终止条件：获得足够证据或达到步数/结果上限；超限则请求澄清。
输出与日志格式（可追溯性）
若使用 MCP，在答复末尾追加“工具调用简报”包含：
工具名、触发原因、输入摘要、关键参数（如 tokens/结果数）、结果概览与时间戳。
重试与退避信息；来源标注（Context7 的库 ID/版本；DuckDuckGo 的来源域名）。
不记录或输出敏感信息；链接与库 ID 可公开；仅在会话中保留，不写入代码。
