Learning objectives

  • Review diffs for correctness, tests, and clarity
  • Leave actionable comments without noise
  • Understand ACK culture and CI expectations

study // plan

Lessons are primers. Depth comes from required reading, interactive labs, reflection, and a hands-on check with evidence — the BOSS study pattern.

Reflection prompts

  1. Explain Code Review Practice to a teammate without jargon — what problem does it solve?
  2. What would break in production if you misunderstood Code Review Practice?
  3. Which BIP, book chapter, or Core doc is authoritative here, and what did you verify?

Lab // Contribution artifact

Produce a contribution artifact for Code Review Practice: issue shortlist, review notes, or PR draft that a maintainer could act on.

evidence required

  • ·Issue URL(s) or PR URL
  • ·Written approach / review checklist
  • ·Self-score against the meaningful-PR rubric

Reviewing is how Bitcoin stays safe. You will learn more from careful review than from rushing another feature PR.

What to check

  1. Does it solve the claimed problem?
  2. Are there tests?
  3. Are edge cases handled?
  4. Is the diff minimal?
