…persist per session (fixes #4452) - Add thinking/effort.py: resolve_reasoning_params() translates a unified off|minimal|low|medium|high level to each provider's native parameter (OpenAI/xAI reasoning_effort, Anthropic/Gemini extended-thinking budget; non-reasoning models silently ignored). - llm.py: emit the native param in _build_completion_params (single chokepoint); revive the dead thinking_budget as a backward-compatible alias. - agent.py: accept reasoning_effort= and thread it into the LLM request pipeline; keep thinking_budget as an alias. - session/store.py: persist reasoning_effort on the session record and add get_session_reasoning_effort() so resume restores it (mirrors #3685). - Tests: 21 new unit tests (translation, agent surface, session persistence).

Greptile SummaryThe PR translates portable reasoning-effort levels into provider-native request parameters and adds CLI session persistence and restoration.
Confidence Score: 4/5The PR is not yet safe to merge because explicitly disabling reasoning on a resumed session can silently re-enable the previously stored effort. The restore path collapses explicit Files Needing Attention: src/praisonai-code/praisonai_code/cli/commands/run.py; src/praisonai-code/praisonai_code/cli/state/project_sessions.py

When a session using reasoning_effort is continued, the normal metadata flush does not write this field and the resume path restores only the model. The new getter is therefore never given persisted production data or called during resume, so the session silently uses the current or default effort.

These tests stop at inspecting _build_completion_params and never call agent.start() with a real prompt. This bypasses provider dispatch and response handling, allowing end-to-end incompatibilities in the new feature to pass the suite.

…me (#4452) 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 <noreply@anthropic.com> Co-authored-by: Mervin Praison <MervinPraison@users.noreply.github.com>

There was a problem hiding this comment.
When a user resumes a session with --thinking off, thinking_to_budget represents the explicit value as None, so this condition restores the session's previous effort and applies it to the request. Reasoning remains enabled instead of being disabled, and the old effort is persisted again for subsequent resumes.
