v0.1.0 - Initial Release

[0.1.0] — 2026-07-15

Added

• agent_loop() — agentic loop with bounded parallel tool execution.
• agent_loop_stream() — streaming variant yielding text chunks and a final LoopResult, with robust mid-stream retry handling.
• LoopResult — str subclass carrying iterations, elapsed time, token usage, and cached-token metadata.
• ToolRegistry — per-instance @registry.tool() decorator for sync and async Python tools.
• JSON Schema validation for tool schemas at registration time and for LLM arguments at execution time.
• Tool signature validation (rejection of positional-only parameters, matches with schema parameters, checks for request-scoped state).
• Concurrency limiting at loop iteration (max_parallel_tools) and worker process (max_global_tools) levels.
• ThreadPoolExecutor offloading for sync tools with automatic process-exit shutdown and leak-free memory management of EventLoop instances.
• Timeout guards for tool executions (tool_timeout, tool_queue_timeout) and the overall agent loop (agent_timeout).
• Size limits for tool arguments, tool outputs, message history, and file uploads.
• HTTP request body and backpressure guardrails (MAX_HTTP_BODY_BYTES, MAX_CONCURRENT_REQUESTS, MAX_QUEUE_BACKLOG).
• Timing-safe multi-key Bearer token authentication support.
• CORS configuration middleware via CORS_ORIGINS.
• Strict production-ready configuration checks on startup (LUGHUS_ENV=production).
• OpenTelemetry traces and metrics integration for monitoring loop metrics, token usage, and tool execution.
• BaseSettings dataclass loading settings dynamically from the environment and local .env files (with built-in python-dotenv support).
• Scaffolding tool (lughus new CLI command) with dynamic .env.example generation.
• Testing utilities MockLLM and MockStreamingLLM.
• Local browser developer test UI at /ui (packaged as lughus.ui_server assets) with live event streaming, Jaeger trace integration, and robust SSRF / DNS Rebinding protection.
• Shell injection hardening for A2A filename extraction in gateway.py.
• CI workflow configuration with pytest, coverage, mypy, and ruff.
• py.typed PEP 561 typing support marker.
