• Specification as a first-class craft - writing clear, testable intent and acceptance criteria that agents and humans can both act on.
• Review and quality judgement - evaluating AI-generated work for correctness, security and design fit, rather than typing every line yourself.
• Orchestration - composing and supervising AI capabilities and agentic workflows inside governed pipelines with clear quality gates.
• Raising the team, not just yourself - turning good individual practice into shared, reusable capability so the whole team gets faster, not just one person.
