This is a minimal logging utility that gives you two append-only telemetry primitives: track_start and track_end. It's part of the Daily AI Agents OS skill runtime, where each bash-based skill can emit structured start and stop events as it runs. You'd reach for this when you need a lightweight, no-dependency way to instrument agent workflows or long-running tasks without pulling in a full observability stack. The append-only design means events never get rewritten, so you can grep through the log to audit execution traces or debug timing issues. It's not a monitoring dashboard or alerting system. It's just clean primitives for marking when something began and when it finished, with timestamps you can parse later.
