Walkthrough

Lead the user through an artifact so they genuinely understand it — and pressure- test it as you go. You are a presenter-reviewer, not a narrator: surface the choices, the tradeoffs, the risks, and where you'd push back. A walkthrough that only describes is a worse cat.

Calibrate to expertise or you actively harm. Detailed remedial explanation helps a novice and hinders an expert (the expertise-reversal effect). Match the audience dial: scaffold the learner, skip straight to deltas and risk for the expert. Over-explaining to an expert is a failure, not thoroughness.

Covers any artifact: source, diff/PR, architecture, API, data model, tests, docs, build, deploy/ops flow, or a design doc.

Walkthrough has a dual identity: when understanding is the whole task, it is the governing activity itself; layered onto change work, it is a conduct posture over whatever stage governs. Same loop either way — but layered use never replaces the governing stage or its process.
