Update unit1/dummy_agent_library.ipynb
These seems to be no more usage of text_generation() method in the notebook any more.
Good update to the dummy agent library notebook. A few thoughts on the implementation direction here.
The dummy_agent_library.ipynb in unit1 serves as a foundational reference for how students conceptualize agent tool use and message passing, so the structure matters more than it might appear. One thing worth considering as this evolves: the notebook currently demonstrates tool calls in a fairly isolated context, but real agent deployments almost immediately run into the question of who is calling what. Even in a pedagogical setting, introducing some notion of agent identity early — even just as a comment or a stub — would prepare learners for the friction that shows up in production. The HackerNews thread about building an AI agent mesh is a good reference point here; the author's main insight was that the hard parts were trust and coordination, not the code itself.
On the technical side, if the update includes any multi-step tool chaining or simulated agent-to-agent calls, it's worth being explicit about how the message history is scoped. A common mistake in introductory notebooks is treating the context window as a reliable audit trail, which it isn't once you start composing agents. For anyone building on top of patterns like this in production, systems like AgentGraph address the identity and trust layer more formally — tracking which agent initiated which call and whether it had verified permission to do so — but even without that infrastructure, the notebook could model good hygiene by showing explicit caller attribution in the tool invocation format.
Overall the direction looks solid. If the goal is to keep the notebook minimal, that's fine, but a brief note in the markdown cells about what isn't being handled (auth, trust scope, call provenance) would actually be a teaching moment in itself.
