fix(editors): stop treating the agy CLI as the Antigravity IDE

[ishaanko]

Problem

Open In lists Antigravity on machines that only have the Antigravity CLI. The editor list matched agy, which the IDE owned when #841 added it. Google has since split the products:

Product	macOS bundle	CLI
Antigravity (Hub)	Antigravity.app	none
Antigravity CLI	none	agy
Antigravity IDE	Antigravity IDE.app	antigravity-ide, agy-ide

The CLI installer puts agy in ~/.local/bin on macOS and Linux. Since #12439, install-folder discovery also searches ~/.local/bin on Linux, so the CLI is found there even when it is not on PATH.

The Zed half of #5078 was fixed on main by #12439.

Fix

• Antigravity matches antigravity-ide and agy-ide. antigravity-ide comes first because fix: detect installed editors outside PATH #12439 builds the bundle path from the first command.
• The macOS bundle lookup uses Antigravity IDE.app instead of the Antigravity.app Hub.

On Linux, the IDE install script and packages expose antigravity-ide, which the existing folder search already covers. On Windows, PATH detection works as before. I could not confirm the IDE's Windows install folder name, so a Windows IDE install that is not on PATH may still go undetected.

Verification

vp test run apps/server/src/process/externalLauncher.test.ts   # 41 passed, 1 skipped
vp run --filter @t3tools/contracts --filter @t3tools/shared --filter t3 typecheck
vp lint on the three touched files

Five new cases, all failing on main before the fix:

• The agy CLI does not list Antigravity: on PATH on macOS, in ~/.local/bin off PATH on Linux, and as agy.cmd on PATH on Windows.
• Antigravity IDE.app with no PATH shim is found and launched with --goto on macOS.
• ~/.local/bin/antigravity-ide is found and launched on Linux.

UI changes

Both screenshots come from a Mac with agy on PATH and without the Antigravity IDE. The Zed entry in the second screenshot now comes from #12439.

Before, the Open in button defaults to Antigravity:

After, Antigravity is gone:

Fixes #5078

Implemented with Claude Opus 5.5 via Claude Code.

Summary by CodeRabbit

• Bug Fixes
  • Antigravity IDE is now recognized and launched using its IDE-specific commands, with file-position navigation supported.
  • The standalone agy CLI is no longer mistaken for the Antigravity IDE on macOS, Linux, or Windows.

📝 Walkthrough

Walkthrough

The Antigravity editor configuration now checks antigravity-ide and agy-ide instead of agy, while retaining goto launch behavior. The shared install-name map labels it Antigravity IDE. Tests cover macOS and Linux IDE discovery and launch, and exclusion of standalone agy across platforms.

Changes

Antigravity IDE discovery

Layer / File(s)	Summary
Antigravity editor identity packages/contracts/src/editor.ts, packages/shared/src/editor.ts	The Antigravity command list now uses antigravity-ide followed by agy-ide. The shared install-name mapping labels the editor Antigravity IDE and distinguishes it from Antigravity.app.
Discovery and launch coverage apps/server/src/process/externalLauncher.test.ts	Tests cover macOS and Linux IDE discovery and --goto launch arguments. Platform-specific tests verify that the standalone agy executable is not discovered as Antigravity.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Bug fix · Severity of issue fixed: Low

Suggested reviewers: juliusmarminge

Merge Risk: ⚪ Minimal · up to 1c337

The change separates Antigravity IDE detection from the standalone CLI, with no identified issue requiring resolution before merge.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 1c337

The change directs Antigravity discovery toward IDE executables instead of the standalone CLI. It does not appear to add a new launch path, but permission checks around callers were not established by the available evidence.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The effective change is to the local executable selected for Antigravity discovery and launch. The examined paths show neither a new remote-opening capability nor a new service dependency.

Trust Boundaries and Controls

• observed — Executable selection still trusts a command found on PATH ahead of install-location candidates. That lookup order is in the existing resolver; the PR changes the Antigravity candidates passed to it, not the lookup order.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR changes macOS editor discovery and process launching by adding app-bundle detection and routing Antigravity through open -a, creating direct user-visible runtime impact despite its narrow scope and tests. The supplied unresolved review thread identifies a concrete wrong-process launch scenario, so human verification is warranted.
