How long does the integration take?

Change one base URL in an OpenAI-compatible client, or install the Python or TypeScript SDK; the quickstart routes a first request in a few minutes.

Will this lock us into another vendor?

No. The router is Apache-2.0 open source, your provider keys stay yours, and the API is OpenAI-compatible, so leaving is a change of base URL.

What happens when a provider fails?

The router falls back to the next model your policy allows and records the fallback in the trace, so an outage costs a retry, not an incident.

T5 - Prompt - OpenSmartRoute

Prompt file imported from Crazykimwipe/Crest (.codex/prompts/T5.md). Copyright stays with the author.

T5（docs/codex-tasks.md）だけを実装。最初に AGENTS.md、設計書 §5.1–5.2、タスク定義を読む。

Vite + React + TypeScript + Tailwind の空のPWA足場、manifest、Service Worker、engine Worker、workspace配線を作る。@crest/engine の公開 segment を呼べる最小テストを、英語・日本語（Latin混在例を含む）で書く。toAtoms は内部実装なので公開を要求しない。

作業範囲: apps/web/（ただし apps/web/src/frequency/ は変更禁止）、必要最小限の root package.json / pnpm-lock.yaml / workspace・設定ファイル、.codex/out/T5.md。読書ループ実装・依存の過剰追加・他タスク・マージは禁止。

最初に npx --yes pnpm@9.12.0 install。lint/test/buildを全て通す。曖昧な仕様判断が必要なら実装せず QUESTION: でHALT。完了時は変更ファイル、検証結果、判断を .codex/out/T5.md に記録する。

Install T5 and it becomes one more candidate the router can pick - when it fits.

A listing is a routing target with a manifest: what it does, which domains it covers, what it costs and who publishes it. Once installed it sits beside your own models and tools, is scored like any other candidate for each request, and shows up in the trace when it wins. Ratings come from workspaces that installed it, one per account.
