- Fix: Direct rawRPC('GetCascadeTrajectorySteps') polling every 5s
- Relay: PLANNER_RESPONSE, NOTIFY_USER, TASK_BOUNDARY, WAITING steps
- Added: docs/discord-bridge-analysis.md (full SDK architecture analysis)
- Added: docs/devlog/entries/20260308-003.md (trial-and-error history)
- Added: antigravity-sdk-main/ source reference
- Vikunja: #252 done, #253 created, #251 commented

# Legal Notice
## Disclaimer
This project is an unofficial, community-maintained SDK for building extensions
for [Antigravity IDE](https://antigravity.dev). It is **not affiliated with,
endorsed by, or sponsored by Google LLC or any of its subsidiaries.**
## Nature of the Project
Antigravity SDK provides a **TypeScript library** for VS Code extension
developers who want to build tools that work within Antigravity IDE.
The SDK interacts with Antigravity exclusively through:
- **VS Code Extension API** — the standard, documented `vscode.*` namespace
that all extensions use
- **Registered commands** — commands exposed by Antigravity through the
standard `vscode.commands` interface
- **Local state files** — reading (not writing) locally stored settings
## Compliance
- This SDK **does not access** Google's backend servers, gRPC endpoints,
or authentication systems directly.
- This SDK **does not extract** AI models, training data, weights, or
proprietary algorithms.
- This SDK **does not bypass** security features, licensing, rate limits,
or usage restrictions.
- This SDK **does not proxy** or relay requests to Google's infrastructure.
- All communication goes through Antigravity's own extension host — the same
mechanism used by any VS Code extension.
## Interoperability
This SDK is developed to enable interoperability between Antigravity IDE
and third-party extensions, as provided by:
- **EU Software Directive** (Directive 2009/24/EC), Article 6 — permits
analysis of software for the purpose of achieving interoperability
- **UK Copyright, Designs and Patents Act 1988**, Section 50B
- Similar provisions in other jurisdictions
The API interfaces documented in this project were derived through observation
of Antigravity's public extension API surface — the same surface available to
any VS Code extension running inside Antigravity.
## User Responsibility
Users and extension developers are responsible for ensuring their use of
this SDK and any extensions built with it comply with applicable terms of
service and local laws.
Extension developers should:
1. Not use the SDK to access Google's backend directly
2. Not use the SDK to extract or replicate AI model behavior
3. Not use the SDK to bypass security or licensing restrictions
4. Follow Antigravity's extension guidelines where applicable
## Takedown
If Google or the Antigravity team requests removal of this project, we will
comply promptly. Contact: [open a GitHub issue](https://github.com/Kanezal/antigravity-sdk/issues).
## License
This project is released under the [GNU Affero General Public License v3.0](LICENSE).

GNU AFFERO GENERAL PUBLIC LICENSE
Version 3, 19 November 2007
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
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 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.
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.
Developers that use our General Public Licenses protect your rights
with two steps: (1) assert copyright on the software, and (2) offer
you this License which gives you legal permission to copy, distribute
and/or modify the software.
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.
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.
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.
The precise terms and conditions for copying, distribution and
modification follow.
TERMS AND CONDITIONS
0. Definitions.
"This License" refers to version 3 of the GNU Affero General Public License.
"Copyright" also means copyright-like laws that apply to other kinds of
works, such as semiconductor masks.
"The Program" refers to any copyrightable work licensed under this
License. Each licensee is addressed as "you". "Licensees" and
"recipients" may be individuals or organizations.
To "modify" a work means to copy from or adapt all or part of the work
in 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 or a work "based on" the earlier work.
A "covered work" means either the unmodified Program or a work based
on the Program.
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.
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.
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.
1. Source Code.
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.
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.
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 "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
subprograms and other parts of the work.
The Corresponding Source need not include anything that users
can regenerate automatically from other parts of the Corresponding
Source.
The Corresponding Source for a work in source code form is that
same work.
2. Basic Permissions.
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.
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.
Conveying under any other circumstances is permitted solely under
the conditions stated below. Sublicensing is not allowed; section 10
makes it unnecessary.
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
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.
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.
4. Conveying Verbatim Copies.
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.
You may charge any price or no price for each copy that you convey,
and you may offer support or warranty protection for a fee.
5. Conveying Modified Source Versions.
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:
a) The work must carry prominent notices stating that you modified
it, and giving a relevant date.
b) The work must carry prominent notices stating that it is
released under this License and any conditions added under section
7. This requirement modifies the requirement in section 4 to
"keep intact all notices".
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.
d) If the work has interactive user interfaces, each must display
Appropriate Legal Notices; however, if the Program has interactive
interfaces that do not display Appropriate Legal Notices, your
work need not make them do so.
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.
6. Conveying Non-Source Forms.
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 Source under the terms of this License,
in one of these ways:
a) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by the
Corresponding Source fixed on a durable physical medium
customarily used for software interchange.
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.
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
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.
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

# Antigravity SDK
**Community SDK for building extensions for [Antigravity IDE](https://antigravity.dev)**
[![npm](https://img.shields.io/npm/v/antigravity-sdk)](https://www.npmjs.com/package/antigravity-sdk)
[![License: AGPL-3.0](https://img.shields.io/badge/License-AGPL--3.0-blue.svg)](LICENSE)
[![Sponsor](https://img.shields.io/badge/Sponsor-Support%20this%20project-ff69b4?logo=githubsponsors&logoColor=white)](https://github.com/Kanezal/antigravity-sdk#support)
*Build powerful extensions that work alongside Antigravity's AI agent.*
</div>
---
## What is this?
A TypeScript SDK for building **VS Code extensions** that extend Antigravity IDE. It gives you programmatic access to the agent's conversations, preferences, step control, real-time activity monitoring, and a declarative API for integrating custom UI directly into the Agent View — all through Antigravity's own extension protocols.
> [!IMPORTANT]
> This SDK is designed **exclusively** for building Antigravity extensions. It is **not** a tool for integrating Antigravity with third-party applications, extracting data, or proxying requests. See [Compliance](#compliance).
---
## Quick Start
```bash
npm install antigravity-sdk
```
```typescript
import { AntigravitySDK } from 'antigravity-sdk';
export async function activate(context: vscode.ExtensionContext) {
const sdk = new AntigravitySDK(context);
await sdk.initialize();
// List conversations with real titles
const sessions = await sdk.cascade.getSessions();
console.log(`${sessions.length} conversations`);
// Read all 16 agent preferences
const prefs = await sdk.cascade.getPreferences();
console.log('Terminal policy:', prefs.terminalExecutionPolicy);
// Monitor agent activity in real time
sdk.monitor.onStepCountChanged((e) => {
console.log(`${e.title}: +${e.delta} steps`);
});
sdk.monitor.onActiveSessionChanged((e) => {
console.log(`Switched to: ${e.title}`);
});
sdk.monitor.start();
// Accept/reject agent steps programmatically
await sdk.cascade.acceptStep();
await sdk.cascade.acceptTerminalCommand();
context.subscriptions.push(sdk);
}
```
---
## Features
### Agent View UI Integration
The SDK provides **9 integration points** in the Agent View panel — add buttons, metadata, badges, menu items, and interactive elements with a fluent, declarative API. Everything is theme-aware and survives Antigravity updates via auto-repair.
```typescript
import { IntegrationManager, IntegrationPoint } from 'antigravity-sdk';
const ui = new IntegrationManager();
// Fluent API — chain calls
ui.addTopBarButton('stats', '📊', 'Show Stats', {
title: 'Session Stats',
rows: [{ key: 'Steps:', value: '42' }],
})
.addInputButton('tokens', '🔢', 'Token Counter')
.addTurnMetadata('meta', ['turnNumber', 'userCharCount', 'aiCharCount', 'codeBlocks'])
.addUserBadges('badges', 'charCount')
.addBotAction('inspect', '🔍', 'Inspect Response')
.addDropdownItem('export', 'Export Chat', '📋')
.addTitleInteraction('title', 'dblclick', 'Double-click to bookmark');
await ui.install();
ui.enableAutoRepair(); // Survives Antigravity updates
```
| Integration Point | Location | Use Cases |
|-------------------|----------|-----------|
| `TOP_BAR` | Header icon bar | Session overview, navigation |
| `TOP_RIGHT` | Before close button | Status indicators, quick toggle |
| `INPUT_AREA` | Next to send button | Token counter, prompt templates |
| `BOTTOM_ICONS` | Bottom icon row | Mode switches, quick actions |
| `TURN_METADATA` | Inside each turn | Character count, code block stats, turn numbers |
| `USER_BADGE` | User message bubble | Message length indicator |
| `BOT_ACTION` | Next to Good/Bad | Response analysis, copy actions |
| `DROPDOWN_MENU` | 3-dot overflow menu | Export, settings, debug tools |
| `CHAT_TITLE` | Conversation title | Rename, bookmark on interaction |
> [!NOTE]
> The integration script runs in the renderer process, independent of the extension. The SDK uses a **heartbeat mechanism** to prevent orphaned integrations: `sdk.initialize()` refreshes a timestamp marker, and the script silently exits if the marker is stale (48h). Disabling your extension will automatically stop the integration on the next IDE restart after the grace period.
### Conversation Management
Full control over Cascade conversations — list, create, switch, send messages, and manage agent steps.
```typescript
// List sessions with titles, step counts, timestamps
const sessions = await sdk.cascade.getSessions();
// Switch to a conversation
await sdk.cascade.focusSession(sessions[0].id);
// Send a message to the active chat
await sdk.cascade.sendPrompt('Analyze this file');
// Create a background conversation
const id = await sdk.cascade.createBackgroundSession('Run tests quietly');
```
### Real-Time Event Monitoring
Watch for state changes as they happen — new conversations, step progress, session switches, preference updates.
```typescript
// Agent made progress (added steps)
sdk.monitor.onStepCountChanged((e) => {
statusBar.text = `${e.title}: step ${e.newCount}`;
});
// User switched to a different conversation
sdk.monitor.onActiveSessionChanged((e) => {
console.log(`Now viewing: ${e.title}`);
});
// New conversation created
sdk.monitor.onNewConversation(() => {
console.log('New conversation detected');
});
// Any USS state changed (preferences, settings, etc.)
sdk.monitor.onStateChanged((e) => {
console.log(`${e.key}: ${e.previousSize}${e.newSize} bytes`);
});
sdk.monitor.start(3000, 5000); // USS poll: 3s, trajectory poll: 5s
```
### Agent Step Control
Programmatically accept, reject, or run agent actions — build approval workflows, auto-accept policies, or custom review UIs.
```typescript
await sdk.cascade.acceptStep(); // Accept code edit
await sdk.cascade.rejectStep(); // Reject code edit
await sdk.cascade.acceptTerminalCommand(); // Accept terminal command
await sdk.cascade.rejectTerminalCommand(); // Reject terminal command
await sdk.cascade.runTerminalCommand(); // Run pending command
await sdk.cascade.acceptCommand(); // Accept non-terminal action
```
### State & Preferences
Read the agent's current settings — terminal policies, secure mode, sandbox config, and more. Decoded directly from protobuf sentinel values.
```typescript
const prefs = await sdk.cascade.getPreferences();
prefs.terminalExecutionPolicy // OFF | AUTO | EAGER
prefs.artifactReviewPolicy // ALWAYS | TURBO | AUTO
prefs.secureModeEnabled // boolean
prefs.terminalSandboxEnabled // boolean
prefs.shellIntegrationEnabled // boolean
prefs.allowNonWorkspaceFiles // boolean
// ... 16 preferences total
```
### IDE Diagnostics
Access system information, extension logs, and recent conversation metadata.
```typescript
const diag = await sdk.cascade.getDiagnostics();
console.log(diag.systemInfo.operatingSystem);
console.log(diag.systemInfo.userName);
console.log(diag.isRemote); // SSH?
// MCP URL, browser port, git status
const mcpUrl = await sdk.cascade.getMcpUrl();
const browserPort = await sdk.cascade.getBrowserPort();
const ignored = await sdk.cascade.isFileGitIgnored('secret.env');
```
### Headless Cascade (LSBridge)
Create and manage conversations programmatically through the Language Server — no UI flicker, no panel switching.
```typescript
import { Models } from 'antigravity-sdk';
// Create a headless cascade with model selection
const cascadeId = await sdk.ls.createCascade({
text: 'Analyze test coverage in this project',
model: Models.GEMINI_FLASH,
});
// Send follow-up messages
await sdk.ls.sendMessage({
cascadeId,
text: 'Now fix the failing tests',
model: Models.GEMINI_PRO_HIGH,
});
// Focus in UI when ready
await sdk.ls.focusCascade(cascadeId);
// Or make raw RPC calls to any of the 68 verified LS methods
const status = await sdk.ls.getUserStatus();
const cascades = await sdk.ls.listCascades();
```
> [!NOTE]
> LSBridge auto-discovers the Language Server port and CSRF token from the running LS process. If auto-discovery fails (sandboxed environments), use `sdk.ls.setConnection(port, csrfToken)` manually.

vscode.commands.executeCommand()
+ read-only state.vscdb (sql.js)
```
> [!NOTE]
> The SDK uses `sql.js` (pure JS/WASM SQLite) instead of `better-sqlite3` because Antigravity's Electron ABI (v140 / Node v22.21.1) is incompatible with native modules. This was verified in runtime.
---
## Compliance
> [!CAUTION]
> **Token extraction is a violation of Google's Terms of Service.**
>
> The SDK **actively blocks** access to authentication tokens (`oauthToken`, `agentManagerInitState`, and other sensitive keys). Any attempt to read these keys will throw an error.
>
> Extracting, storing, forwarding, or reusing Antigravity OAuth tokens — directly or through third-party tools — violates Google's TOS and may result in account termination.
### What this SDK is for
- Building **VS Code extensions** that run inside Antigravity IDE
- Extending Antigravity's functionality for your own workflows
- Adding custom UI elements to the Agent View
- Monitoring and automating agent step approval
- Reading preferences and conversation metadata
### What this SDK is NOT for
- Integrating Antigravity with external applications or services
- Proxying or relaying requests to Google's infrastructure
- Extracting AI model outputs for training other models
- Accessing Google's backend servers, gRPC endpoints, or auth systems
- Building alternative clients or wrappers around Antigravity
### How it works
All SDK communication goes through three safe, local channels:
1. **`vscode.commands.executeCommand()`** — the standard VS Code Extension API that all extensions use. Antigravity decides what to execute.
2. **Read-only local state** — the SDK reads `state.vscdb` for preferences and metadata, never writes.
3. **Local Language Server** — the SDK communicates with the LS process on `127.0.0.1` using the same ConnectRPC protocol that Antigravity itself uses. Authentication is via an ephemeral per-session CSRF token (not the user's OAuth token). No data leaves the local machine through this channel.
The SDK includes a `SENSITIVE_KEYS` blocklist that prevents extension developers from accidentally (or intentionally) accessing authentication data.

# Discord Bridge 딥 디버깅 — 시행착오 기록
- **시간**: 2026-03-08 05:30~07:00
- **Vikunja**: #252 → done, #253 진행중, #251 코멘트 추가
## 시행착오 요약 (소거법)
### ❌ 시도 1: Bot 재시작 불필요
- **가설**: Bot이 죽어서 메시지가 안 간다
- **현실**: Bot은 PID 25508로 정상 동작 중이었음
- **배움**: Bot 프로세스 확인은 `Get-Process -Name python | Select PID,StartTime`
### ❌ 시도 2: 수동 테스트 파일 깨짐 (BOM 인코딩)
- **가설**: Bot이 파일을 안 읽는다
- **현실**: `cmd /c echo {...} > file.json`이 BOM(FF FE) 포함 UTF-16 생성
- **배움**: **테스트 파일은 PowerShell Set-Content -Encoding UTF8 사용**
- **증거**: Bot 로그에 `Expecting property name enclosed in double quotes` 반복
### ❌ 시도 3: getDiagnostics 기반 진단 폴링 무의미
- **가설**: getDiagnostics 데이터로 step 변화를 잡을 수 있다
- **현실**: `getDiagnostics.recentTrajectories.lastStepIndex`**실시간 업데이트 안 됨**
- **증거**: POLL#1~#2 모두 `steps=1237 known=0` 고정 (실제 step은 1239+)
- **배움**: **getDiagnostics는 세션 메타데이터용, 실시간 step 추적 불가**
### ❌ 시도 4: SDK EventMonitor 의존 불가
- **가설**: SDK monitor.onStepCountChanged가 실시간 감지
- **현실**: EventMonitor._pollTrajectories()가 getDiagnostics 사용 → stale
- **배움**: **SDK EventMonitor는 실시간 step 추적에 부적합**
### ✅ 최종 해결: rawRPC 직접 폴링
- `GetCascadeTrajectorySteps` rawRPC는 **실시간 step 데이터를 정확히 반환**
- 5초 간격 폴링으로 PLANNER_RESPONSE, NOTIFY_USER, TASK_BOUNDARY, WAITING 릴레이
- `getDiagnostics`는 active session ID 확인 용도로만 (최초 + 60초마다)
## 핵심 교훈
| # | 교훈 | 카테고리 |
|---|------|----------|
| 1 | `cmd /c echo`로 JSON 만들지 마라 (BOM) | Windows |
| 2 | `getDiagnostics.lastStepIndex`는 stale | SDK |
| 3 | SDK EventMonitor는 getDiagnostics 의존 | SDK |
| 4 | `rawRPC('GetCascadeTrajectorySteps')`만 실시간 | SDK |
| 5 | Step control은 `vscode.commands` 사용 | SDK |
| 6 | 분석 문서는 brain이 아닌 프로젝트 docs에 저장 | 프로세스 |

# Discord Bridge 디버깅 분석 로그
> 날짜: 2026-03-08
> 세션: e7b46728-6c7d-4220-b45a-d79e5a8c2318
## 1. Step Type 전체 매핑 (775 steps)
`GetCascadeTrajectorySteps` RPC로 현재 세션의 775개 step을 덤프한 결과:
| Step Type | 횟수 | Statuses | Data Key | Discord 전달 여부 |
|-----------|------|----------|----------|------------------|
| PLANNER_RESPONSE | 218 | DONE | plannerResponse | ✅ AI 응답 (핵심) |
| EPHEMERAL_MESSAGE | 186 | DONE | ephemeralMessage | ❌ 내부 시스템 알림 |
| RUN_COMMAND | 81 | DONE, CANCELED | runCommand | ✅ 명령 실행 (WAITING 시) |
| TASK_BOUNDARY | 71 | DONE | taskBoundary | 🟡 작업 진행 상태 |
| USER_INPUT | 38 | DONE | userInput | 🟡 사용자 입력 |
| VIEW_FILE | 38 | DONE | viewFile, permissions | ❌ 파일 읽기 |
| CODE_ACTION | 36 | DONE, ERROR | codeAction, error | ✅ 파일 수정/생성 (WAITING 시) |
| ERROR_MESSAGE | 33 | DONE | errorMessage | ❌ 에러 |
| GREP_SEARCH | 18 | DONE | grepSearch | ❌ 검색 |
| NOTIFY_USER | 18 | DONE | notifyUser | ✅ 사용자 알림 |
| VIEW_CODE_ITEM | 9 | DONE | viewCodeItem | ❌ 코드 조회 |
| CONVERSATION_HISTORY | 7 | DONE | conversationHistory | ❌ 대화 이력 주입 |
| KNOWLEDGE_ARTIFACTS | 7 | DONE | knowledgeArtifacts | ❌ KI 주입 |
| CHECKPOINT | 7 | DONE | checkpoint | ❌ 세션 체크포인트 |
| LIST_DIRECTORY | 4 | DONE | listDirectory, permissions | ❌ 디렉토리 조회 |
| VIEW_FILE_OUTLINE | 2 | DONE | viewFileOutline | ❌ 파일 아웃라인 |
| FIND | 2 | DONE | find | ❌ 파일 검색 |
### PLANNER_RESPONSE 구조
```json
{
"thinking": "내부 사고 과정 (SKIP)",
"response": "사용자 대면 텍스트",
"modifiedResponse": "정리된 버전 (있으면 우선 사용)",
"toolCalls": [{"name": "...", "argumentsJson": "..."}],
"thinkingDuration": "0.9s",
"stopReason": "STOP_REASON_STOP_PATTERN"
}
```
### WAITING 상태 미관측
775 steps 중 `WAITING` 상태가 **0개**. 이유:
1. `SafeToAutoRun=true` → WAITING 없이 바로 실행
2. 이미 승인/거부된 step → DONE/CANCELED로 변환
3. `GetCascadeTrajectorySteps`는 완료된 step만 반환하는 것으로 보임
---
## 2. SDK 아키텍처 분석 (antigravity-sdk v1.6.0)
### 전체 구조
```
AntigravitySDK
├── commands: CommandBridge ← vscode.commands.executeCommand 래퍼
├── state: StateBridge ← state.vscdb (USS) 직접 읽기
├── cascade: CascadeManager ← 대화 관리 + step control
├── monitor: EventMonitor ← 상태 변화 감지 (polling)
├── ls: LSBridge ← Language Server RPC (rawRPC)
└── integration: IntegrationManager ← Agent View UI 커스터마이즈
```
### EventMonitor (transport/event-monitor.ts)
- **USS 폴링**: `state.vscdb` 키 크기 변화 감지 (setInterval)
- **Trajectory 폴링**: `antigravity.getDiagnostics``recentTrajectories[].lastStepIndex` 비교
- 데이터 소스: `vscode.commands.executeCommand('antigravity.getDiagnostics')`
- `recentTrajectories`는 최근 10개 대화만 포함
### Step Control (cascade/cascade-manager.ts)
| 메서드 | VS Code 명령어 | 용도 |
|--------|----------------|------|
| `acceptStep()` | `antigravity.agent.acceptAgentStep` | 코드 수정 승인 |
| `rejectStep()` | `antigravity.agent.rejectAgentStep` | 코드 수정 거부 |
| `acceptTerminalCommand()` | `antigravity.terminalCommand.accept` | 터미널 명령 승인 |
| `rejectTerminalCommand()` | `antigravity.terminalCommand.reject` | 터미널 명령 거부 |
| `acceptCommand()` | `antigravity.command.accept` | 비터미널 액션 승인 |
| `rejectCommand()` | `antigravity.command.reject` | 비터미널 액션 거부 |
> **핵심**: Step control은 **vscode.commands**, rawRPC가 아님!
---
## 3. 파이프라인 테스트 (소거법)
### 파이프라인 구조
```
Extension step event → 텍스트 추출 → chat_snapshots/*.json 쓰기
→ Bot scanner (5초) → Discord 전송
```
### 테스트 결과
| Stage | 테스트 | 결과 |
|-------|--------|------|
| 1. Step 감지 | onStepCountChanged | ✅ step 1239 (+2) |
| 1. 등록 | register 파일 | ✅ e7b46728→gravity_control |
| 2. 텍스트 추출 | PLANNER_RESPONSE | ✅ 24 chars |
| 3. 파일 쓰기 | chat_snapshots/*.json | ✅ 파일 생성됨 |
| 4. Bot 스캔 | chat_snapshot_scanner | ✅ 정상 동작 (정상 JSON) |
| 5. Discord 전송 | 채널 전송 | ✅ 수동 테스트 파일 도착 |
### 핵심 문제 발견
**`getDiagnostics.recentTrajectories.lastStepIndex`가 실시간 업데이트되지 않는다.**
Console POLL 데이터:
```
[POLL#1] e7b46728 steps=1237 known=0 "Debugging Discord Bridge"
[POLL#2] e7b46728 steps=1237 known=0 "Debugging Discord Bridge"
```
- `steps=1237` — getDiagnostics에서 반환하는 lastStepIndex
- 실제로는 1239+ steps가 존재 (step event는 1239 감지)
- 이후 대화 턴에서 step이 계속 추가되지만 `lastStepIndex`는 1237에서 변하지 않음
- 결과: SDK EventMonitor가 변화를 감지 못함 → `onStepCountChanged` 미발생
### `known=0` 문제
- POLL에서 `known=0` = `lastSeenStep` 맵이 비어있음
- step event에서 `lastSeenStep.set()`이 실행되어야 하지만,
one-time full dump의 async 대기 중에 POLL이 먼저 실행될 수 있음
- MISSED STEPS 복구 조건이 `known > 0`이라 초기 상태에서 작동 안 함
---
## 4. 남은 문제 & 다음 단계
### 근본 원인
`getDiagnostics``lastStepIndex`가 실시간 반영되지 않아
SDK EventMonitor의 trajectory polling이 새 step을 감지하지 못함.
### 적용된 해결책 (2026-03-08 06:55)
**PRIMARY RELAY 완전 재작성**: `getDiagnostics` 의존 제거, 직접 `rawRPC` 폴링
```
setInterval (5초마다):
1. getDiagnostics로 active session ID 확보 (초회 + 60초마다 갱신)
2. rawRPC('GetCascadeTrajectorySteps', {cascadeId, startStepIndex}) 직접 호출
3. step count 변화 감지 → 새 step 추출
4. PLANNER_RESPONSE → chat_snapshots (AI 응답)
5. NOTIFY_USER → chat_snapshots (알림)
6. TASK_BOUNDARY → chat_snapshots (작업 상태)
7. WAITING → pending approval (승인 대기)
```
이 방식은 `getDiagnostics.lastStepIndex`의 stale 문제를 완전히 우회함.
