Week 3 – Skill Architecture, Tooling & Curing Prompt/Skill Bloat

Focus: Designing clean, single-purpose skills/tools in Python while preventing token bloat, tool confusion, and context drift.

Learning Outcomes

• Distinguish System Prompts, Retrieval Augmentation, and Agentic Tools/Skills.
• Define clear JSON schemas and docstrings for Vertex AI Function Calling.
• Avoid the “tool overload” problem through dynamic skill routing.
• Apply least-privilege and prompt-injection defenses for skills that process untrusted DFDs.

Agenda

1. Theory – Anatomy of a skill, bloat mitigation, security
2. Lab 3.1 – Modular skills + Pydantic + tool registry
3. Lab 3.2 – Dynamic Skill Router
