About agtop

agtop is a top-style ratatui TUI that walks /proc on Linux
(sysinfo on Windows / macOS / *BSD) plus the on-disk session
transcripts of Claude Code, OpenAI Codex, Block Goose, Aider,
and Google Gemini. For each detected agent it reports CPU,
RSS, status, current tool / task, in-flight subagents,
cumulative token usage, estimated cost, context-window fill,
loaded skills, and a live transcript preview.

On Windows, writable-FD enumeration uses NtQuerySystemInformation
+ DuplicateHandle to surface what files each agent has open.
Per-process IO byte counters come from sysinfo's disk_usage().
