Like in the title: hooks that are covered . When working in claude code it was quite efficient to gather a full conversation transcript, prepare it and feed it directly the conversation transcript (stripped from unnecessary parts) to keep the conversation flow going on. There are also other uses: prompt injecting summarization agent with additional instructions on how the conversation should be shaped in the summary without the need to adjust the summarization prompt.

Both of these uses are possible when having proper injections. However, there are other lifecycle possibilities, like: reinjecting AGENTS.md after summarization (for better alignment after summarization), reminders etc.

There are other hooks that are important in the lifecycle of an application, however most are already covered: SubAgentStart is replaced with SessionStart for an agent (however it would be nice to give some kind of distinction: subagents may need different message on SessionStart than a main agent (so that they are less talkative, or more talkative - if we would like to adjust that behavior)), pre and post tool use hooks are there, same as stop hook.
