class meta_package_manager.managers.antigravity.Antigravity_CLI_Plugins

Bases: PackageManager

The plugins of the Antigravity CLI, agy.

A package is a plugin of the user’s profile, identified by the name its plugin.json declares, and stored under ~/.gemini/config/plugins. Plugins a project keeps in its own .agents/plugins directory are not reported: the listing covers the profile alone, whatever the working directory.

install takes a local plugin directory, or <plugin>@<marketplace> for a marketplace the Antigravity application registered: the command line has no way to add one, and no search. The plugin is then listed under its name.

The CLI itself updates with agy update, which is not a plugin operation and is left to topgrade.

Initialize cli_errors list.

operation_notes: ClassVar = {'installed': 'Listings carry plugin names only, with no version.', 'outdated': 'No command reports a newer plugin.', 'search': 'No catalog is reachable from the command line: marketplaces are browsed in the Antigravity application.', 'upgrade': 'No update command: the Antigravity application updates plugins.', 'upgrade_all': 'No update command: the Antigravity application updates plugins.'}

Per-operation hints rendered in the Notes column of the manager page’s Operations table.

Keyed by the Operations member name, each value is a single short sentence explaining why the manager lacks the operation, or what makes its implementation partial: the pointer a reader needs to judge whether the gap is one they could help close. Each sentence starts with a capital and closes with a period, and starts on a word rather than a code span, so the cell reads standalone beside its row. A blank cell stays silent: a manager documenting nothing documents no gap.

The full rationale never lives here: it belongs in a comment beside the implementing method (or beside this declaration, for an operation with no method to hang it on), so the sentence on the page stays a hint and the code keeps the story. The class docstring follows the same split: it keeps only what a user needs to run the tool day to day, never how mpm wraps it.

Validated by test_operation_notes, which also checks every key matches a real operation: a key outside the enum’s vocabulary would never reach a page.

name: str = 'Antigravity CLI plugins'

Return package manager’s common name.

Default value is based on class name.

homepage_url: str | None = 'https://antigravity.google/product/antigravity-cli'

Home page of the project, only used in documentation for reference.

Left unset when the home page is the project’s repository, which repository_url names on its own, and when it is the project’s manual, which documentation_url names. Never inherited, like the other links.

documentation_url: str | None = 'https://antigravity.google/docs/plugins?tab=cli'

Entry point of the project’s own documentation, or None when it has none.

The manual, the documentation site, or the man page of the CLI mpm drives: whichever page a user reads to learn the commands this manager wraps. Listed between homepage_url and repository_url in the links of the manager’s page, so a reader reaching for the tool’s reference finds it in the box of facts rather than in the prose below it.

Left unset where a link would state a fact twice or invent one: a tool documenting itself in its repository alone, whose README repository_url already reaches. A page about the ecosystem rather than the tool does not qualify either.

Where a project’s only site is its manual, that address belongs here and homepage_url stays unset: the slot names what the page is, and a reader reaching for the reference looks under the documentation link.

Never inherited, like every other link: the AUR helpers extending pacman each document themselves.

List of platforms supported by the manager.

Allows for a mishmash of platforms and groups of platforms. Will be normalized into a frozenset of Platform instances at instantiation.

requirement: str | None = '>=1.2.14'

The release this wrapper was driven against. The changelog dates none of the plugin commands, so earlier releases are unverified.

cli_names: tuple[str, ...] = ('agy',)

List of CLI names the package manager is known as.

This list of recognized CLI names is ordered by priority. That way we can influence the search of the right binary.

..hint::

This was helpful in the case of the Python transition from 2.x to 3.x, where multiple versions of the same executable were named python or python3.

By default, this property’s value is derived from the manager’s ID (see the MetaPackageManager.__init__ method above).

version_regexes: tuple[str, ...] = ('^(?P<version>\\d+\\.\\d+\\.\\d+)',)

The bare version, alone on its line.

$ agy --version
1.2.14

property installed: Iterator[Package]

Fetch installed packages.

The listing is a JSON document, except with no plugin at all, where it prints No imported plugins. instead of an empty array.

$ agy plugin list
{
  "imports": [
    {
      "name": "apricot-notes",
      "source": "antigravity",
      "importedAt": "2026-09-30T09:08:27Z",
      "components": null
    }
  ]
}

id: str = 'antigravity-cli-plugins'

Package manager’s ID.

Derived by defaults from the lower-cased class name in which underscores _ are replaced by dashes -.

This ID must be unique among all package manager definitions and lower-case, as they’re used as feature flags for the mpm CLI.

install(package_id, version=None)

Install one package.

$ agy plugin install ~/plugins/apricot-notes

Return type:

str

repository_url: str | None = None

Repository holding the project’s code, or None when it has no public one.

Linked from the manager’s documentation page. Also what the weekly metrics sample reads: docs/docs_update.py writes it into the [tool.repomatic.metrics] subjects of pyproject.toml when its forge answers the sampler, through a mirror for a forge that does not.

Never inherited, for the same reason as wikipedia_url: the AUR helpers extending pacman each live in a repository of their own.

virtual: bool = False

Should we expose the package manager to the user?

Virtual package manager are just skeleton classes used to factorize code among managers of the same family.

wikipedia_url: str | None = None

English Wikipedia article about the project, or None when it has none.

Listed last in the links of the manager’s documentation page. The article covers the project that home page names, or is a redirect Wikipedia keeps under the project’s name, landing on the part of a broader article that describes it: Cargo_(software) opens the Cargo section of the Rust article. An article that merely mentions the project does not count, nor does one about a related subject: lazy is a Neovim plugin manager, and the Neovim article is not about it.

Never inherited: the metaclass resets it to None on any class not declaring its own. A subclass often wraps a distinct project, like the six AUR helpers extending pacman, and would otherwise present pacman’s article as its own. Documentation-only, like homepage_url.

remove(package_id)

Removes a package.

Caution

agy reports the removal of a plugin it never had.

$ agy plugin uninstall apricot-notes
Uninstalled plugin "apricot-notes"

Return type:

str
