seoDescription: "gh-aw v0.91.4–v0.91.8: model routing and fallback, the Agy engine, Git-backed work queues, unified session timelines, and security hardening."

Five releases shipped in [github/gh-aw](https://github.com/github/gh-aw) this week, from [v0.91.4](https://github.com/github/gh-aw/releases/tag/v0.91.4) to [v0.91.8](https://github.com/github/gh-aw/releases/tag/v0.91.8). The themes: smarter model routing, new engine options, and sturdier sandboxes.

Agent sessions now render as full elapsed-time timelines, with consistent trace normalization across Copilot, Codex, Claude, Gemini, Pi, Kiro, Aider and AGY.

- **Built-in graders**: a new `code-read-precision` trajectory grader and builtin grader defaults loaded from setup-action JSON.

- **Model routing**: Copilot wire APIs are selected from AWF metadata and model mismatches are surfaced. The firewall moved to v0.28.51.

- **Hardening**: a custom grader sandbox escape was closed, and workflow YAML, scanner file handling and temp-file writes were tightened.

- **Memory validation**: declarative JSON schema validation for memory, with repairable invalid repo-memory baselines.

This release introduces a native Go Agy engine ([#66998](https://github.com/github/gh-aw/pull/66998)) and deprecates the Gemini engine in its favor ([#66941](https://github.com/github/gh-aw/pull/66941)), so plan to migrate Gemini workflows.

- **Work queue upgrades**: priority-aware conformance dispatch ([#67222](https://github.com/github/gh-aw/pull/67222)) and scoped GitHub Issues mirrors ([#67025](https://github.com/github/gh-aw/pull/67025)).

- **Better model visibility**: routed model and effort are reported across outputs ([#66963](https://github.com/github/gh-aw/pull/66963)), plus per-agent spend ([#66961](https://github.com/github/gh-aw/pull/66961)).

- **Secret detection** now covers all AWF environment sources ([#67017](https://github.com/github/gh-aw/pull/67017)).

- **Git-backed fair DAG work queues** with claim-scoped effects ([#66024](https://github.com/github/gh-aw/pull/66024)).

- **Model routing** across Claude, Codex, and pi ([#66723](https://github.com/github/gh-aw/pull/66723)).

- **Stricter `pull_request_target` checkouts** via an explicit strict-mode policy ([#66649](https://github.com/github/gh-aw/pull/66649)).

- **Ordered engine model fallback** keeps workflows running when a preferred model is unavailable ([#66593](https://github.com/github/gh-aw/pull/66593)).

- **`auto` and `copilot/auto` models** now work in Pi, Codex, and Claude ([#66567](https://github.com/github/gh-aw/pull/66567)).

- **New `gh aw fix` codemods** for Copilot web-fetch and reserved inputs ([#66556](https://github.com/github/gh-aw/pull/66556)).

[v0.91.4](https://github.com/github/gh-aw/releases/tag/v0.91.4) adds support for [Claude Code with GitHub Copilot inference](https://github.com/github/gh-aw/pull/66289) and [local-first workflow debugging](https://github.com/github/gh-aw/pull/66270).

Documentation Unbloat reviews the docs and simplifies verbose pages while keeping them clear and complete.

This week it ran every night on its schedule at about 01:15 UTC. All three runs we looked at (October 10, 11 and 12) succeeded, taking between 7 and 10 minutes and producing one safe output each.

Its stated mission is to make docs shorter, so it spends its nights trimming words, which is a bit like a barber who works only while you sleep.

💡 **Usage tip**: Pair a scheduled editor like this with a `/unbloat` slash command so you can also trim a specific page on demand.
