  1. May 2026 Agents · · 4 min Agent observability — traces, tokens, and costs in RedDB Most Claude Code setups can't answer "what did the agent cost me last sprint?" or "which tools dominate p99 latency?".

A SessionStart hook reads top-K memories into context, a /remember slash command writes them, and RedDB stores rows, vectors, and audit log in one transaction.
