From 85c5e459e272da8dcce4a54f5a8a01fc109b5e23 Mon Sep 17 00:00:00 2001 From: Paul Furgale Date: Mon, 14 Sep 2026 12:38:05 +0000 Subject: [PATCH 01/25] feat: extract single-tool CodeAct and Todo delegation prerequisites Bring the shared strategy, task state and bounded context renderer needed by current benchmark agents onto main. Preserve canonical assistant turns and cache ordering. Include tool-name compatibility in trace consumers and the generated viewer assets. This contains no ACP or terminal-host implementation.

02/25] feat(bench): backport current benchmark agents and runner Adopt compact single-tool execution, automatic summarization, method writing and bounded same-kind delegation with Todo merging. Add the rlm variant, runner cleanup, deterministic behavior reports and ledger validation. Count python_cell alongside legacy execute_python while excluding framework prefill. Add real runner/delegation regressions preserving provider turns and remove unrelated native-worker and branch-ledger test dependencies.
