Context Timeline Hook for Claude Code: Track Context & Sub-Agents

Managing the context window and sub-agents launched in Claude Code is difficult, because it’s hard to keep track of everything.

So we made this hook. It’s called Context Timeline.

It starts immediately when you open a session and shows a timeline with the main agent’s context window and how sub-agents start working in their own separate contexts.

Each launched sub-agent is displayed in real time.

This way you can manage the context and sub-agents and see everything in a simpler view than in the console.
