Monitor live coding-agent sessions with Abtop

Use Abtop when an operator is supervising several local coding-agent sessions and needs an at-a-glance operational dashboard. The workflow is to install the CLI, launch `abtop`, inspect active Claude Code, Codex CLI, and OpenCode sessions, watch token and context-window pressure, spot rate-limit risk, detect child processes and open ports, and jump back to the selected terminal session when intervention is needed. The same workflow can emit a one-shot or JSON snapshot for scripts, status checks, or local dashboards. Invoke this instead of opening each product normally when multiple agents are running across projects and the bottleneck is observability, not code generation. The boundary is read-only local monitoring and session triage for active agent CLIs, using local process and file state rather than remote account access. It is not a generic terminal UI, metrics library, or coding-agent product. Keep it focused on supervision, debugging, and local capacity awareness. Avoid treating snapshots as remote telemetry.
