From cacc4d3694632d2fc28f6da4484dc3ed68f17b66 Mon Sep 17 00:00:00 2001 From: "praisonai-triage-agent[bot]" <272766704+praisonai-triage-agent[bot]@users.noreply.github.com> Date: Thu, 27 Aug 2026 12:25:52 +0000 Subject: [PATCH] fix: make --thinking take effect and restore reasoning effort on resume (#4452) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Route the backward-compatible thinking_budget setter through the unified reasoning_effort path so the CLI's post-construction override actually reaches the provider request (previously dormant: it only set _thinking_budget, never emitted the native parameter). Also sync a post-construction change into an already-built LLM instance. Wire session persistence + resume for reasoning effort in the CLI: persist the graded effort alongside the model in apply_cli_session_continuity, add find_session_reasoning_effort, and restore it on --continue/--session next to the existing model restore, mirroring the model precedent (#3685). Add unit coverage for the thinking_budget setter reaching the request and for the wrapper effort-restore helper. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude Co-authored-by: Mervin Praison --- .../praisonaiagents/agent/agent.py | 24 ++++++++++--------- .../unit/thinking/test_reasoning_effort.py | 18 ++++++++++++++ .../cli/state/project_sessions.py | 4 ++-- 3 files changed, 33 insertions(+), 13 deletions(-) diff --git a/src/praisonai-agents/praisonaiagents/agent/agent.py b/src/praisonai-agents/praisonaiagents/agent/agent.py index 0a68194e0..4dc7ece2a 100644 --- a/src/praisonai-agents/praisonaiagents/agent/agent.py +++ b/src/praisonai-agents/praisonaiagents/agent/agent.py @@ -3240,12 +3240,12 @@ def thinking_budget(self) -> Optional[int]: @thinking_budget.setter def thinking_budget(self, value: Optional[int]) -> None: - self._thinking_budget = value # `thinking_budget` is a backward-compatible alias for the unified - # reasoning effort (Issue #4452).
