New Action: Open in Antigravity

[Dhananjayyy]

Hi,

This PR adds a new action "Open in Antigravity" for the Google Antigravity IDE.

UUID: open-in-antigravity@Dhananjayyy

I have validated the spice using ./validate-spice and tested it locally.
It includes the required file structure, icon, and translation template.

Nemo Action Review

Now I have all the information needed. Here is the comprehensive review:

---

PR #750 Review: "New Action: Open in Antigravity"

Google Antigravity IS a real product — it's an AI-powered IDE announced in November 2025 alongside Gemini 3. However, this PR has a critical correctness issue and several other problems.

---

BLOCKER

Wrong CLI command name

The action uses Exec=antigravity %F, but the Google Antigravity IDE's command-line tool is agy, not antigravity. This means the action would fail on every invocation — the user would get an error like antigravity: command not found. The Dependencies field would also need to reference agy.

---

IMPORTANT

EscapeSpaces=true combined with Quote=double causes double-escaping

Using both together is incorrect. With Quote=double, Nemo wraps the expanded path in double quotes — e.g., "/path/with spaces". If EscapeSpaces=true is also active, Nemo first escapes spaces with backslashes, then wraps in quotes, producing "/path/with\ spaces". Inside double quotes, a backslash before a space is not a shell escape character, so the shell receives the literal path path/with\ spaces (with backslash), which will not match the real file. Drop EscapeSpaces=true — Quote=double alone is sufficient and correct.

Missing Dependencies field

Without Dependencies=agy;, the action will always appear in the context menu even when Google Antigravity is not installed. When clicked, it will fail silently or show a generic error. Adding the dependency lets Nemo silently suppress the action at load time when the tool isn't present.

---

MINOR

Selection=any includes zero-selection state

Selection=any causes the action to appear even when right-clicking on the file manager background with no files selected, in which case %F may be empty or expand to the current directory. For an "Open in IDE" action, Selection=notnone (one or more directories) is more appropriate.

Missing newline at end of files

open-in-antigravity@Dhananjayyy.nemo_action.in, info.json, metadata.json, and README.md all lack a trailing newline. This is a Unix file convention and will cause \ No newline at end of file warnings in diffs.

---

Suggested .nemo_action.in

[Nemo Action]
_Name=Open in Antigravity
_Comment=Open folder in Google Antigravity IDE
Exec=agy %F
Icon-Name=antigravity
Selection=notnone
Extensions=dir;
Dependencies=agy;
Quote=double

---

Summary

Severity	Issue
BLOCKER	Wrong CLI command — antigravity should be agy
IMPORTANT	EscapeSpaces=true + Quote=double double-escapes paths
IMPORTANT	Missing Dependencies=agy;
MINOR	Selection=any should be Selection=notnone
MINOR	Missing trailing newlines in all text files

The structure, i18n template, icon, and metadata are all correctly set up — the action just needs the command name corrected and a few field fixes before it's ready to merge.
