Tutorial adds JSON session persistence to a basic Python AI agent
Part of a series. It adds a SessionStore, transcript preservation and atomic writes, with code in a companion repo.
What the research found
Part of a tutorial series on building a basic AI agent in Python; this part adds JSON-file session persistence with a SessionStore, transcript preservation, and atomic writes, with code in a companion repo.
Claims and how well the evidence supports them
- Sessions are stored as JSON files in a sessions directory beside the memory notes, with id, timestamps, summary and messages 97%
- SessionStore keeps a working messages list plus a full transcript that survives compaction 98%
- Messages are serialized via model_dump(exclude_none=True) to preserve tool call IDs 91%
- Writes go to a temp file, fsync, then atomic os.replace 97%
