Guides / Agent skills
Reusable instructions for scoping, building, reviewing, and coordinating work. Each skill includes an explanation and files to take with you.
Product thinking · 13 min read
Work through a reading-list feature from a vague request to a finished brief, precise behavior, and the first executable tests.
Take away: A completed product brief, a URL policy with tests, and a reusable skill for the next ambiguous request.
AI engineering · 12 min read
Build a support-ticket triage core that can say “I could not complete this,” survive duplicate requests, and stop before exhausting its allowance.
Take away: A runnable triage core, seven tests of failure and contract behavior, and a plan for taking the same boundaries into a database-backed service.
Design & UX · 13 min read
Follow one reader through a save, a duplicate, and a failed request. Turn the findings into a working form, recovery behavior, and repeatable tests.
Take away: An interactive reading-list lab, its complete HTML source, a tested state transition, and a worked review worksheet.
Agent workflows · 12 min read
Split a reading-list feature between API and interface work, make their agreement executable, and integrate the result without relying on reassuring handoffs.
Take away: A concrete ownership plan, a shared request/response contract, four executable contract checks, and an integration procedure.
