Agent Tools Get Back-Pressure Surfaces

Fresh Gemini CLI and OpenWork patches show agent products turning hangs, publish failures, voice quotas, and provider outages into explicit runtime behavior.

A rough marker diagram titled The Hang Became A Signal, with evidence cards for Gemini CLI, OpenWork, Antigravity, and rate limits pointing to failures becoming runtime surfaces.

google-gemini/gemini-cli merged Ramón Medrano Llamas's June 21 PR #28063, replacing a scheduler busy wait with a timer yield after the PR described macOS parallel tool calls hanging at full CPU.

Facts

The Gemini CLI commit be7ba2c22 changes packages/core/src/scheduler/scheduler.ts from queueMicrotask to setTimeout(resolve, 10).
The same PR adds --ignore-scripts to workspace package publishing and extends the parallel-tools integration test timeout.
different-ai/openwork commit 831d6ad adds managed OpenWork Models voice sessions with rate-limit handling, broker response validation, and direct OpenAI fallback on broker 503.
Antigravity CLI release 1.0.10 adds log-path exposure, auth handling, shell fixes, permission matching fixes, and settings preservation.

Evidence

The receipts are a Gemini scheduler diff, a release-publish action diff, OpenWork voice broker code, OpenWork usage-limit code, and Antigravity release notes. They are separate patches with the same operational shape: make failure, slowdown, or fallback visible.

Context

For builders and operators, this is the unglamorous layer that decides whether an agent system feels dependable. A hung tool wave, exhausted voice bucket, broken publish job, or failed auth path becomes easier to diagnose when the product exposes a surface for it.

Limits

This is not a shared standard and it is not proof that the failures are solved everywhere. Antigravity's authentication issue #415 remains open in public metadata, and OpenWork's managed voice path depends on configured broker credentials.

Primary Evidence

Gemini CLI PR #28063: https://github.com/google-gemini/gemini-cli/pull/28063

Evidence used: the PR describes workspace publish failures and scheduler event-loop starvation during parallel tool execution on macOS.

Gemini CLI merge commit be7ba2c22: https://github.com/google-gemini/gemini-cli/commit/be7ba2c22adf095880b81da26f1afcc48520eebc

Evidence used: the commit changes scheduler yielding, release publishing, and parallel-tool integration tests.

Gemini CLI scheduler source after the merge: https://github.com/google-gemini/gemini-cli/blob/be7ba2c22adf095880b81da26f1afcc48520eebc/packages/core/src/scheduler/scheduler.ts

Evidence used: waiting active calls now yield with setTimeout(resolve, 10).

OpenWork managed voice commit 831d6ad: https://github.com/different-ai/openwork/commit/831d6adfa07585a34364de5bc74df3a78b7801d7

Evidence used: the commit adds managed voice sessions, broker response validation, 503 fallback, and charging transaction notes.

OpenWork inference voice route: https://github.com/different-ai/openwork/blob/831d6adfa07585a34364de5bc74df3a78b7801d7/ee/apps/inference/src/voice.ts

Evidence used: the route returns rate-limit status, retry headers, and usage-limit messages when voice buckets are exhausted.

Antigravity CLI 1.0.10 release: https://github.com/google-antigravity/antigravity-cli/releases/tag/1.0.10

Evidence used: release notes list log-path exposure, auth handling, permission matching, settings preservation, and shell fixes.

Antigravity issue #415: https://github.com/google-antigravity/antigravity-cli/issues/415

Evidence used: public issue metadata and thread keep the 1.0.9 authentication breakage unresolved as a limit.

Evidence Limits

These are independent project changes, not a common standard or coordinated release.

The evidence shows product and runtime surfaces for failure and recovery; it does not prove all named failures are fully fixed.

OpenWork's managed voice path depends on configured OpenWork Models or OpenAI credentials.

Antigravity's public repo exposes release notes and issue traffic, not full implementation diffs for the 1.0.10 changes.
