Show more session info: running process, titlebar, working directory

[andrewgazelka]

Summary

Enhance tap to display more context about the running session, making it easier to understand what's happening in each terminal.

Proposed Features

• Running process: Show the current foreground process name (e.g., vim, cargo, node)
• Terminal title: Capture and display the terminal title if the application sets it via OSC escape sequences
• Working directory: Track and display the current working directory (via OSC 7 or similar)
• Session duration: Show how long the session has been running
• Command history: Optionally track commands executed in the session

Implementation Ideas

• Parse OSC escape sequences for title/cwd updates
• Use /proc/<pid>/stat or similar to get foreground process info
• Store metadata in session info JSON
• Expose via MCP and socket API
