  • Integrate official Antigravity ACP binary and harden connection lifecycle

Summary by CodeRabbit

  • New Features
    • Antigravity now uses Google’s official ACP server, which Pipper installs on first use. Sign in through the setup card to connect your account.
    • Antigravity tool approval requests appear in Pipper for review.
  • Bug Fixes
    • Unanswered permission requests are cancelled after two minutes instead of being automatically approved.
    • Failed Antigravity session restoration keeps the saved conversation available rather than silently starting a replacement. Older CLI-bridge sessions require a new Antigravity thread.
  • Documentation
    • Updated Antigravity setup instructions to reflect in-app installation and sign-in.

RetriggerConfidence Score: 0/5

The PR does not appear safe to merge while workspace deletion can discard local work and repository setup can commit sensitive files.

Findings

  1. P1 Additional Antigravity accounts cannot install ▶
  2. P1 Legacy threads block project launch ▶
  3. P1 Cold installs outlast thread switches ▶
  4. P1 Late replay alters saved history ▶
  5. P1 Cancelled activation reports success ▶
  6. P1 Failed nonce write strands lock ▶
  7. P1 Failed restores lose prompts ▶
  8. P2 Authentication failure loses its banner ▶
  9. P2 Corrupt cache passes validation ▶
  10. P2 Active installer loses its lock ▶
  11. P2 Installation success remains untested ▶
  12. P2 Legacy thread error hidden ▶

Summary

The PR integrates Google’s official Antigravity ACP server, its installation and authentication flow, and snapshot-preserving restoration. Changes merged since the previous review also introduce provider accounts and an Advanced workspace interface with Git and GitHub actions.

  • The new workspace deletion and repository setup paths need safeguards against losing local work or committing sensitive files.
  • Account restoration and first-use Antigravity installation need to account for non-default provider instances.
  • Advanced workspace selection and Git/PR state have several workflow gaps.

📝 Walkthrough

Walkthrough

Pipper replaces the Antigravity CLI adapter with Google’s pinned ACP server, installed in a versioned cache. The change adds in-app authentication, updates session restoration behavior, and makes unanswered permission requests cancel after two minutes.

Changes

Official Antigravity ACP integration

Layer / File(s) Summary
Install and launch the official ACP server
ANTIGRAVITY-INTEGRATION-REPORT.md, electron/agents/*, electron/connection-lifecycle.ts, src/store/agent-store.ts, marketing/src/pages/docs/agents.astro
The registry selects the cache-installed binary. The installer verifies releases, validates cached files, and coordinates installation. The connection lifecycle waits for installation before launch. Setup copy describes the updated installation and sign-in flow. Tests cover cache reuse, checksum failures, stale locks, and platform-specific extraction.
Discover and complete agent authentication
electron/agents/handshake-probe.ts, electron/agent-connection-manager.ts, electron/main.ts, electron/preload.ts, src/electron.d.ts, src/components/agent-auth-actions.tsx, src/components/agent-selector.tsx, src/components/agent-panel.tsx, src/store/agent-store.ts
The handshake exposes authentication methods. The setup card and agent panel display supported sign-in actions. The Electron bridge forwards authentication to the connection manager, which records authentication-required errors and can retry activation after sign-in.
Handle ACP session and configuration behavior
electron/agent-connection-manager.ts, electron/antigravity-snapshot-restore.test.ts, electron/push-state-snapshot.test.ts
Antigravity uses different configuration-option handling. Restoration failures preserve snapshot-restored runtimes, and legacy CLI session IDs produce an error instead of falling through to a replacement session. The thread tool-call payload condition and snapshot test are also updated.
Cancel unanswered permission requests
electron/permission-coordinator.ts, electron/permission-coordinator.test.ts
Unanswered permission requests now resolve as cancelled after the timeout instead of selecting an allow option. The test expects the cancelled outcome.

Merge Risk: 🔵 Low · up to 7c4f2

The remaining issues are bounded: a later connection error may be hidden, and a malformed sign-in request may start an unnecessary connection. The PR is mergeable with owner awareness and follow-up.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 7c4f2

The new integration changes how an agent is installed, launched, signed in, and allowed to use tools. A malformed sign-in request can start an agent before the request is rejected. First-use setup for a separate Antigravity account may also fail. The launch effect is limited to agents the app already registers, but live sign-in and Windows behavior have not been fully verified.

Retained concerns

  • Low · security · observed: The new sign-in entrypoint acquires a registered agent connection before rejecting an invalid authentication method. A renderer caller can thus trigger installation or process startup with a malformed method ID. Existing agent-launch entrypoints limit the incremental reachability; this does not establish arbitrary process execution.
  • Medium · reliability · inferred: On a cold cache, an Antigravity account instance whose ID differs from its driver ID can skip the first-use installer, then fail when spawn resolution requires the installed binary. An earlier installation through the driver can mask this account-setup rollout failure.
Security review details

Security Blast Radius

  • inferred — The malformed-authentication path is reachable through the renderer bridge and can affect registered agent processes and the local first-use download. Descriptor lookup rejects unknown agents; no arbitrary executable, other tenant, or remotely reachable caller was established.

Security Findings and Attack Paths

  • observed — The retained security condition is acquisition before method validation: a renderer caller supplies a valid registered agent ID and invalid method ID, causing connection acquisition before rejection. Existing renderer agent-switch and thread-creation paths already reach acquisition, limiting the incremental authority shown.

Trust Boundaries and Controls

  • observed — Electron mediates agent startup and ACP permission responses. Advertised authentication methods bound requests after acquisition, while pending approvals are keyed by session and request and cancel when unanswered. The normal UI supplies a request ID when answering a queued approval.

Resilience and Maintainability Implications

  • observed — Approval timeout changed from automatic selection of an allow option to cancellation. Failed restores keep saved history read-only and reject waiting prompts, reducing the chance that recovery silently operates on a replacement session.

Hardening Proposals

  • proposed — Bound or authorize cold connection acquisition on the sign-in path independently of a supplied method ID, so rejected requests cannot repeatedly trigger expensive installation or startup.
  • proposed — Consider checking cached executable contents before later launches, rather than treating matching file sizes and an installation marker as ongoing integrity proof.

P1 Legacy threads block project launch When a returning user's project opens on a legacy pipper-agy- thread, this error stops activation before launch:complete creates the main window. The failure path also removes the restored thread from memory, so the user cannot open the project to view its saved history or start a replacement thread. Preserve snapshot-only access even though the official server cannot resume that session.

P1 Cold installs outlast thread switches If the Antigravity cache is empty and the first download takes more than 60 seconds, the renderer reports a failed thread switch while this awaited installation continues in the main process. The download can take up to 180 seconds, so activation may later publish the target thread after the UI has reported failure. Align the switch timeout and cancellation behavior with first-use installation.

P2 Authentication failure loses its banner If an existing Antigravity thread's session/load fails with “Authentication required,” this condition hides the persistent switch error. That failure does not set authRequiredMessage, and the sign-in buttons are only in the launch-window setup card. Once the switch toast disappears, the workspace offers neither a lasting explanation nor an in-place sign-in action.

P2 Corrupt cache passes validation A matching install.json and two present files are treated as proof that the cached release is intact. If an executable is truncated or replaced but remains present, it is repeatedly spawned instead of being repaired; the cache-reuse test even passes with files containing only "fixture".

P2 Active installer loses its lock If an installation runs for more than five minutes, another process treats its unchanged lock timestamp as stale even though extraction has no five-minute limit. Both installers can then remove and replace the same cache directory, and the first installer's cleanup can remove the second installer's lock. Verify lock ownership before reclaiming or releasing it.

P2 Installation success remains untested These tests cover a fabricated cache hit and a bad checksum, but not successful Windows extraction or sign-in followed by session/new in a fresh server process. Both paths are needed by the supported Windows target and the new setup flow; without success-path coverage, archive-layout and cross-process sign-in regressions can go undetected.

Note: If this suggestion doesn't match your team's coding style, reply to this and let me know. I'll remember it for next time!

Address review findings on the official Antigravity ACP integration:
- Keep a snapshot-restored Antigravity runtime when its session cannot be
  established, and let project launch open it snapshot-only instead of
  failing before the main window is created.
- Bound the first-use install wait and widen the renderer switch timeout so
  a slow download cannot report failure and then publish the thread late.
- Record auth_required on session load/resume and surface a persistent
  in-place sign-in banner in the workspace.
- Verify cached file sizes and heartbeats/ownership-check the install lock.
- Share sign-in buttons and hide unsupported auth methods (gemini-api-key,
  terminal).
- Add install success/corrupt-cache/lock tests and snapshot-restore tests.

src/components/agent-panel.tsx:2016
🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Suppress an error only when the auth banner exists.

isAntigravityAuthFailure matches messages such as “Authentication failed,” but recordAuthRequired does not set authRequiredMessage for every error with that text. When the message matches without an ACP auth_required rejection, this condition hides the error and Line 2493 renders no replacement banner. Base suppression on the actual snapshot.authRequiredMessage, not the error-text pattern alone.

P1 Failed nonce write strands lock If creating the installer lock succeeds but writing its nonce fails—for example, if storage fills between those operations—the error escapes before lock cleanup. It leaves an open handle and a fresh lock file. Even after storage is freed, a retry cannot install Antigravity until the lock becomes stale roughly five minutes later.

Address the follow-up review on the snapshot-restore fallbacks:
- Drop late session/load replay updates for a preserved, unready snapshot
  runtime so an abandoned request cannot rewrite the saved transcript.
- Reject prompts on a snapshot-only thread before appending a local entry,
  and remove pending entries when an in-progress load fails.
- Reconcile the open tab and workspace on a snapshot-only project launch, and
  rethrow superseded activations instead of reporting a failed launch.
- Close and remove a lock whose nonce write fails so a retry is not stranded.
- Render the auth banner from an extracted component and suppress the raw
  switch error only when that banner is actually shown.
- Extend snapshot-restore tests for late replay, rejected prompts, superseded
  activation, and pending-entry cleanup.

P2 Legacy thread error hidden If one Antigravity restore reports auth_required and the user then switches to a saved legacy Antigravity thread, that thread’s “earlier CLI bridge” error is hidden merely because the connection still carries the sign-in message. The persistent banner tells the user to sign in instead of explaining that this thread cannot be resumed.

Suppress only duplicate authentication errors.

When an Antigravity snapshot has authRequiredMessage, this condition hides every agentError. An unrelated error, such as a connection failure during a retry, then disappears from the panel. Check whether agentError is an authentication failure before suppressing it.

In `@src/components/agent-panel.tsx` at line 2019, Update the agent-error
visibility condition in the panel to suppress an error only when it is an
authentication failure and the Antigravity authentication banner is visible;
keep unrelated errors, such as connection failures during retries, visible. Use
the existing authentication-error indicator or classification rather than
treating `authRequiredMessage` alone as proof that `agentError` is an
authentication failure.

P1 Additional Antigravity accounts cannot install On a cold install, an additional Antigravity account has an instance ID rather than the exact ID antigravity-acp, so this installation step is skipped. Spawn still requires the downloaded binary, causing account probing and activation to fail until the default account installs it.

Validate agent:authenticate arguments before acquiring a connection.

The preload bridge forwards renderer values without runtime validation. For a valid agentId, authenticateAgent can spawn or acquire the agent process before rejecting an empty or non-string methodId. Validate both arguments at the IPC boundary.

Proposed fix
-  ipcMain.handle("agent:authenticate", (_event, agentId: string, methodId: string) =>
-    requireAgentManager().authenticateAgent(agentId, methodId),
-  );
+  ipcMain.handle("agent:authenticate", (_event, agentId: unknown, methodId: unknown) => {
+    if (
+      typeof agentId !== "string" ||
+      agentId.trim() === "" ||
+      typeof methodId !== "string" ||
+      methodId.trim() === ""
+    ) {
+      throw new Error("Invalid authentication request.");
+    }
+    return requireAgentManager().authenticateAgent(agentId, methodId);
+  });
