Session 2: Context Management and Agent Skills

Session 2 continues the context-management thread from Session 1, then introduces agent skills as a way to make repeated workflows reusable.

The main practical shift is that participants should start moving from notebooks as the default working artifact toward Python source files for agent-heavy analysis. Notebooks are useful for teaching and review, but this course is building toward dashboards. For iterative analysis work, a plain .py file or a percent-cell .py file usually gives the agent a simpler artifact to edit, run, inspect, and revise.

Context Management Part 2	How does the working file format change what Codex has to do?	Explain why notebooks can create extra tool use and choose a better working artifact for agent-assisted analysis.
Agent Skills	How can reusable instructions make agent workflows more consistent?	Distinguish prompts, project rules, and skills, then create or evaluate a small analytics skill.
