What it does
claude-esp is a terminal app written in Go that shows the output Claude Code normally hides, such as thinking, tool calls and subagent activity. It runs in a separate terminal, so your main session is not interrupted. You can follow several sessions at once and filter by content type.
Use cases
- 01Debug why a session took an unexpected path
- 02Follow subagent activity in a second terminal
- 03Watch several Claude Code sessions side by side
