Read Antigravity quota through native CLI by pbember · Pull Request #131 · tilorahdotco/meterusage

pbember · 2026-11-14T21:08:45Z

Summary

Problem: Antigravity CLI allowance depended on Docker/Podman even when native AGY and local activity were available.

Result: Read allowance through native agy -p /usage after checking its documented read-only capability. Skip shell wrappers without executing them, retain native local activity, and remove container recovery and volume fallbacks. The CLI manages authentication; no credentials are copied from another app.

Changelog: 2026-11-14.

Evidence

Before: CLI allowance required the container image, volumes and a working Docker/Podman runtime.
After: The native Linux adapter returned five quota windows. Synthetic tests cover wrapper rejection, FIFO discovery, capability gating, cancellation and Windows candidate paths. macOS quota still timed out; native sign-in and installed-app behavior remain unverified.
Screenshots unavailable: this change affects provider collection; no installed candidate was captured.

Merge risk

Rollback: Revert this commit. No data migration or container state changes.

Affected scope: Antigravity CLI allowance and activity. Container-only installations must install the native CLI. Desktop connections keep their existing path.

Verification (agents)

Linux, head 745ea2997759fa33d35a58f96f2fe4604889cd05: pnpm typecheck, pnpm test (1045 passed, 10 skipped), pnpm build, bash tests/scripts/make-app-tests.sh, and git diff --check passed.
Live native Linux quota read passed. macOS report timed out at 30 seconds; no installed-app or native Windows acceptance is claimed.
Commands are bounded to 30 seconds and 1 MiB, with browser launch and CLI auto-update disabled. Errors omit raw command output.
Privacy, setup, provider knowledge and changelog updated. Fixtures are synthetic.

Review (agents)

Independent reviewer: GPT-6.1 Sol, high effort. SHIP for the original source candidate and the latest fixture-isolation commit. No new blocking findings.

Earlier capability-gate, FIFO and Windows-fixture findings have regression coverage. Host-installed CLIs and saved macOS preferences are now excluded from the new fixtures.
The suggested stdout-overflow fix is already implemented in boundedChild (transport.ts:63). The existing real-subprocess regression in providers.test.ts passed; no transport change was needed.
Hosted Linux and Windows CI passed on the reviewed head. CodeRabbit completed with a neutral check. Native macOS/Windows provider acceptance and installed delivery remain open.

Walkthrough

Antigravity quota collection now uses the native agy CLI instead of a container runtime. Activity collection reads local conversation databases or history files.

Changes: Native Antigravity collection

Layer / File(s)	Summary
Native CLI quota collection `src/main/providers/antigravity-cli.ts`, `src/main/composition.ts`, `src/domain/models.ts`, `tests/antigravity-cli.test.ts`, `tests/composition.test.ts`, `tests/platform.test.ts`, `CHANGELOG.md`, `docs/PRIVACY.md`, `docs/electron/README.md`, `docs/kb/providers.md`	The quota provider discovers and validates native CLI candidates, checks changelog support, and runs `agy -p /usage` with a 30-second timeout and 1 MiB output limit. Composition uses the provider, and the tests and documentation describe the native CLI flow.
Local activity collection `src/main/providers/antigravity.ts`, `tests/usage.test.ts`	The activity provider reads conversation databases first and falls back to `history.jsonl`. Tests cover local history, missing data, and cancellation.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Antigravity quota now comes from the native CLI. The new tests can fail on machines that already have the CLI or saved Antigravity Desktop settings. An unusually large usage report could also be read as incomplete without any error. Fix the test isolation and the output-limit handling before merging.

Explanation

The title "Read Antigravity quota through native CLI" matches the main change. The PR switches Antigravity CLI allowance collection from the container-based path to the native agy -p /usage command, and the changeset includes the new native quota provider, its tests, and the removal of the container runtime code. The title is short, specific, and free of noise.

Fail runCommand when stdout exceeds maxBytes.

runCommand drops every stdout chunk after the byte limit and still resolves on a zero exit code. The caller receives a prefix of the output with no error. A quota report that exceeds the limit can therefore lose later quota groups silently. The quota path cannot detect this from the returned text. Reject the command on overflow, as boundedChild already does for its stdout.

This change applies to every runCommand caller that sets maxBytes. Those callers now fail on overflow instead of receiving truncated output.

Add a transport-level test that writes more than the limit to stdout, then asserts rejection. The current mock only checks behavior after Command throws, so it does not cover this path.

Suggested fix for src/main/providers/transport.ts

let capturedBytes = 0; - child.stdout.on("data", (chunk: Buffer) => { capturedBytes += chunk.length; if (capturedBytes <= (options.maxBytes ?? 16 * 1048576)) chunks.push(chunk); }); + const limit = options.maxBytes ?? 16 * 1048576; + child.stdout.on("data", (chunk: Buffer) => { capturedBytes += chunk.length; if (capturedBytes <= limit) chunks.push(chunk); else finish(new Error("Provider output exceeded limit")); });

Isolate these tests from installed native CLIs.

If /opt/homebrew/bin/agy or /usr/local/bin/agy is native, discovery finds it after rejecting the fixture wrapper. Setting PATH does not exclude these fixed candidates.

The wrapper-only test then invokes Command instead of returning cliNotFound. The later-candidate test selects the installed CLI instead of file. Both tests fail on a supported host installation.

Isolate filesystem probes or inject fixture-only candidates for these tests.

Load synthetic preferences for this test.

On macOS, Preferences.load(launch) reads the shared application defaults. If desktopAntigravityIdentity is saved, compose selects the desktop branch. Without connections, quota rejects with notSignedIn instead of returning the expected 25%.

Pass a synthetic rejecting Command to Preferences.load, or use an isolated preference store. The test must not depend on the developer's saved account selection.
