Claude Code + Codex Sessions

Kaomoji telemetry for coding agent transcripts

Scan historical assistant messages from Claude Code and OpenAI Codex, classify the leading kaomoji with BrightWrapper, and see how each agent's expressions change over time.

Per-agent charts

Claude Code and OpenAI Codex are tracked and rendered separately, so styles never blur together.

Daily stacks

Switch between count and proportional views to compare shifts by day.

Incremental scans

Reuse cached classifications and only send unseen messages to BrightWrapper.

Claude Code + Codex archives

Kaomoji frequency console

Scan historical Claude Code and OpenAI Codex transcripts, classify assistant message prefixes with BrightWrapper, and chart the exact kaomoji that were found — separately per agent.

Run scan walks backward through the newest messages of each agent, up to the limit per agent. Clicking a missing timeline gap scans only that agent and date range, up to the same limit. Charts always redraw from the classification cache.
