From 731c6c538d7c615ca0fec89bb428699d1e05a73e Mon Sep 17 00:00:00 2001 From: cabana8471 Date: Tue, 27 Jan 2026 08:09:30 +0100 Subject: [PATCH 1/9] feat: add structured logging system for agent debugging Add a comprehensive structured logging system that saves logs to SQLite at {project_dir}/.autocoder/logs.db for debugging agent issues. New files: - structured_logging.py: SQLite-based logging with WAL mode for concurrency - test_structured_logging.py: 28 unit tests covering all functionality Integration points: - agent.py: Log session lifecycle, tool use, errors, rate limits - parallel_orchestrator.py: Log agent spawn/complete, failures, retries - autonomous_agent_demo.py: Log entry point, interruptions, fatal errors - client.py: Log configuration and API overrides Features: - WAL mode for concurrent access by parallel agents - Query API with filtering by level, agent_id, feature_id, tool_name - Full-text search in messages - Export to JSON, JSONL, CSV formats - Automatic cleanup of old entries - Thread-safe concurrent writes Access logs via: - SQLite: {project}/.autocoder/logs.db - API: GET /api/logs/{project_name} Co-Authored-By: Claude Opus 4.5 --- agent.py | 68 ++++- autonomous_agent_demo.py | 14 + client.py | 16 + parallel_orchestrator.py | 19 +- structured_logging.py | 580 +++++++++++++++++++++++++++++++++++++ test_structured_logging.py | 469 ++++++++++++++++++++++++++++++ 6 files changed, 1156 insertions(+), 10 deletions(-) create mode 100644 structured_logging.py create mode 100644 test_structured_logging.py diff --git a/agent.py b/agent.py index 7d904736..add91b7e 100644 --- a/agent.py +++ b/agent.py @@ -7,6 +7,7 @@ import asyncio import io +import os import re import sys from datetime import datetime, timedelta @@ -16,6 +17,8 @@ from claude_agent_sdk import ClaudeSDKClient +from structured_logging import get_logger + # Fix Windows console encoding for Unicode characters (emoji, etc.) # Without this, print() crashes when Claude outputs emoji like ✅ if sys.platform == "win32": @@ -40,6 +43,7 @@ async def run_agent_session( client: ClaudeSDKClient, message: str, project_dir: Path, + logger=None, ) -> tuple[str, str]: """ Run a single agent session using Claude Agent SDK. @@ -48,6 +52,7 @@ async def run_agent_session( client: Claude SDK client message: The prompt to send project_dir: Project directory path + logger: Optional structured logger for this session Returns: (status, response_text) where status is: @@ -55,6 +60,8 @@ async def run_agent_session( -
