bar-observatory vs agentsilex

bar-observatory: BAR Observatory is an open-source, local-only audit tool for Claude Code sessions, acting as a flight recorder to capture and report every agent action. It provides deterministic reports in JSON, HTML, and Markdown, enabling verification of agent performance without relying on its self-summary or external services.; agentsilex: AgentSilex is a transparent, minimal, and hackable agent framework for developers seeking full control over their AI agents. It prioritizes clarity, allowing users to understand and customize every aspect of their agent's operation without hidden complexity.
