From bbe0948a63a6c92c9d0b48295f67e699a06f8e07 Mon Sep 17 00:00:00 2001 From: Abir Abbas Date: Tue, 24 Feb 2026 14:57:11 -0500 Subject: [PATCH 1/4] issue/right-size-agent-turn-budgets: Replace DEFAULT_AGENT_MAX_TURNS with role-specific budgets Replace hardcoded DEFAULT_AGENT_MAX_TURNS (150) with empirically-derived role-specific turn budgets across all 17 execution agent functions. Changes: - Git utilities (5): 10 turns (git_init, workspace_setup, merger, integration_tester, workspace_cleanup, repo_finalize, github_pr) - Review/QA/advisory (6): 20 turns (retry_advisor, issue_advisor, issue_writer, verifier, qa, code_reviewer, generate_fix_issues) - Synthesis (1): 10 turns (qa_synthesizer) - Strategic reasoning (1): 30 turns (replanner) - Coding (1): 50 turns (coder) All budgets are 2-3x observed p90 turn usage, preventing runaway agents while maintaining headroom for complex cases. Add verification script at scripts/verify_turn_budgets.py to validate all 17 turn budgets match specification via regex parsing. --- scripts/verify_turn_budgets.py | 136 +++++++++++++++++++++++++++ swe_af/reasoners/execution_agents.py | 34 +++---- 2 files changed, 153 insertions(+), 17 deletions(-) create mode 100644 scripts/verify_turn_budgets.py diff --git a/scripts/verify_turn_budgets.py b/scripts/verify_turn_budgets.py new file mode 100644 index 0000000..82a96f5 --- /dev/null +++ b/scripts/verify_turn_budgets.py @@ -0,0 +1,136 @@ +"""Verification script for turn budget right-sizing. + +Tests that all 17 execution agent functions in execution_agents.py have the +correct role-specific max_turns values per the architecture specification. +""" + +import re +import subprocess +import sys +from pathlib import Path + + +def test_all_turn_budgets_match_specification(): + """Verify all 17 agent functions have correct max_turns values.""" + # Expected turn budgets per architecture specification + expected = { + 'run_retry_advisor': 20, + 'run_issue_advisor': 20, + 'run_replanner': 30, + 'run_issue_writer': 20, + 'run_verifier': 20, + 'run_git_init': 10, + 'run_workspace_setup': 10, + 'run_merger': 10, + 'run_integration_tester': 10, + 'run_workspace_cleanup': 10, + 'run_coder': 50, + 'run_qa': 20, + 'run_code_reviewer': 20, + 'run_qa_synthesizer': 10, + 'generate_fix_issues': 20, + 'run_repo_finalize': 10, + 'run_github_pr': 10, + } + + # Read the execution_agents.py file + file_path = Path(__file__).parent.parent / 'swe_af' / 'reasoners' / 'execution_agents.py' + with open(file_path) as f: + content = f.read() + + errors = [] + for func_name, expected_turns in expected.items(): + # Find function definition and extract max_turns value + # Pattern matches: async def func_name(...) followed by AgentAI(AgentAIConfig(...max_turns=N...)) + pattern = rf'async def {func_name}\(.*?max_turns=(\d+)' + match = re.search(pattern, content, re.DOTALL) + + if not match: + errors.append(f'{func_name}: max_turns assignment not found in AgentAIConfig') + continue + + actual_turns = int(match.group(1)) + if actual_turns != expected_turns: + errors.append( + f'{func_name}: expected max_turns={expected_turns}, got {actual_turns}' + ) + + # Assert no errors + if errors: + error_msg = '\n'.join(f' -
