agtop is a process monitor for AI coding agents.

It walks /proc on Linux (sysinfo on macOS, Windows, and *BSD) plus the
on-disk session transcripts of Claude Code, OpenAI Codex, Block Goose,
Aider, and Google Gemini, and presents per-agent CPU, RSS, status,
current tool, in-flight subagents, token usage, estimated cost,
context-window fill, and loaded skills in a top-style ratatui TUI.

On FreeBSD, writable-FD enumeration is provided by libprocstat
(see fstat(1)); per-process IO byte counters are not available
through sysinfo on this platform.

Distribution is also available via crates.io, npm, the AUR, and
a Homebrew tap.
