AI Prototyping Mastery
Worked inside a real codebase, the TaskFlow practice app: explored it with sub-agents, shipped targeted improvements, built a feature three ways, and landed a real pull request.
Builder Bridge
Verified the GitHub CLI and cloned the TaskFlow practice app.
Welcome to The PM Builder
Installed dependencies, ran the TaskFlow practice app, and toured all five pages.
Exploring Codebases
Produced a technical intelligence package on the TaskFlow app: parallel sub-agent exploration, an architecture overview, an end-to-end flow trace, and a feature scoping brief.
Modifying & Improving
Applied the reference pattern — finding how a codebase handles something before changing it — across three targeted improvements, using plan mode and the agent self-verify screenshot loop.
Building Features & Variants
Ran spec-driven development with the /grill-me interview, design-system context, and the /frontend-design skill, building the Team Workload Dashboard in three interaction models and picking a winner.
Git, Safety & Shipping
Ran the git workflow in natural language — branch, commit, push, PR — fixed a real bug with screenshot verification, and shipped a real pull request.
