The topology graph and time-travel replay are genuinely useful additions — most tools in this space flatten agent runs into a linear trace, losing the branching structure entirely. One thing I'd be curious about: how does AgentLens handle the difference between an agent that failed to execute vs one that executed but drifted from its stated goal? Execution traces capture the former well. The latter requires knowing what the agent intended before the tool call happened — which means you need to log the pre-action intent state, not just the post-action result. This matters most for debugging silent failures — cases where all tool calls succeed and costs look normal, but the agent quietly pursued the wrong sub-goal.
