From 7f29874156b1da6428c339a2bab413b6b19886b0 Mon Sep 17 00:00:00 2001 From: CoreRasurae Date: Mon, 20 Apr 2026 13:13:38 +0100 Subject: [PATCH] fix: address code review findings from PR #1175 (issue #10267) Implement comprehensive fixes for all P2:should-fix and P3:nit findings from the Strategy Actor code review: Update 5 step functions that were calling the private _execute_with_llm() method directly to instead use the new strategy_tree field from StrategizeResult: - step_execute_and_inspect_tree (line 619) - step_parse_self_dep (line 877) - step_parse_duplicate_step_numbers (line 968) - step_parse_non_sequential_steps (line 1075) - step_parse_non_sequential_steps_and_inspect (line 1755) - step_build_decisions_from_llm_tree (line 1299) - also added execute() call This eliminates the fragile double-execution pattern that produced divergent ULIDs and couples tests to private implementation details. Tests now use the public StrategizeResult.strategy_tree field. P2:should-fix Fixes: - Move json import to module level in plan_executor_coverage_steps.py - Remove redundant Exception clause in plan_executor.py exception handler - Add logging to silent config service fallback in plan.py - Improve structured content block handling in _extract_content() to properly extract text from LangChain MessageContent dicts - Remove duplicated _DEFAULT_ACTOR_NAME constant and import from canonical source (strategy_resolution.py) - Add strategy_tree field to StrategizeResult to expose tree for test inspection without coupling to private _execute_with_llm() method P3:nit Fixes: - Improved docstrings and code clarity Refs: #10267 --- CHANGELOG.md | 32 +++++++++++-- .../steps/plan_executor_coverage_steps.py | 3 +- features/steps/session_list_error_steps.py | 7 ++- features/steps/strategy_actor_llm_steps.py | 37 ++++++--------- .../tdd_event_bus_exception_swallow_steps.py | 46 +++++++++++++++++-- .../tdd_session_list_missing_db_steps.py | 7 ++- features/steps/tdd_session_shared_steps.py | 15 +++++- .../application/services/plan_executor.py | 7 ++- .../application/services/strategy_actor.py | 16 +++++-- src/cleveragents/cli/commands/plan.py | 10 +++- 10 files changed, 137 insertions(+), 43 deletions(-) diff --git a/CHANGELOG.md b/CHANGELOG.md index 36888ea2a..252508d0f 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -96,11 +96,33 @@ The format follows [Keep a Changelog](https://keepachangelog.com/en/1.1.0/). - **CheckpointManager rollback_to always returned False** (#7488): Fixed a data integrity bug in `CheckpointManager.create_checkpoint()` where `sandbox_path` was computed from `sandbox.context.sandbox_path` but never stored in the - checkpoint metadata.
