Show HN: Agtrace – top and tail -f for AI coding agent sessions (opens in new tab)

Hey HN,

I built agtrace because I kept losing track of what was happening in my Claude Code sessions – context pressure, tool calls, costs.

It's basically `top` for AI coding agents: - Live dashboard showing context window usage and activity - Session history you can query and diff - Works with Claude Code, Codex, and Gemini CLI - 100% local, reads existing logs, no cloud

Install: `npm i -g @lanegrid/agtrace`

The core idea is pointer-based indexing (no log duplication) and schema-on-read (resilient to provider schema changes).

Would love feedback, especially from heavy Claude Code / Codex users.
