Session
A conversation with Claude, with everything that was discussed in it. It stays saved even after you close Claude, so you can resume it later (for example with “claude -c”). A new session starts from zero.
How it appears in the course
A session is a conversation with Claude, with everything that was discussed in it. You type the commands below in the terminal (the first two) or in the conversation (the last two).
Claude reads it automatically at the start of every session (conversation).
If the tools line is missing, the subagent inherits all the tools of the main session. It’s safer to write them explicitly.
