Late to agentic coding? Don't panic, build. | DEM303
Cassidy Williams demonstrates practical, demo-driven agentic coding workflows with GitHub Copilot, focusing on planning work, delegating implementation, reviewing AI-generated pull requests, and shipping changes with guardrails that teams can apply immediately.
Overview
This Microsoft Build 2026 session is a demo-heavy walkthrough of how a team can move from an idea to shipped code using agentic coding patterns.
What the session covers
Planning and delegating work
- Practical patterns for breaking down an idea into tasks.
- Using an issue-driven workflow to plan and track implementation work.
Implementing with GitHub Copilot

Reviewing AI-generated changes
- Reviewing AI-generated pull requests (PRs) as part of the workflow.
- Emphasis on guardrails and review practices to keep quality and safety high.
Shipping with guardrails
- End-to-end workflow focus: from planning to implementation to review to shipping.
