What this chapter is and is not

1. The promise

You'll know what this chapter drills (named, observable behaviours), what it refuses to do (motivational sloganeering), and the rules of evidence used throughout. By the end of this unit you can describe the frame in one sentence.

2. The mental model

This chapter is a driving lesson, not a self-help book. A driving instructor doesn't tell you to be a confident driver. They tell you when to check the mirror, how far to turn the wheel, and which pedal to press at the roundabout.

Every unit in this chapter is one of those — a specific move, in a specific situation, with a specific outcome.

A quick definition: a behaviour is a specific, observable thing a person does. "Posts a PR description with five sections" is a behaviour. "Communicates well" isn't. A grammar is the literal sentence shape used for a behaviour. This chapter gives you grammars for asking questions, leaving reviews, and disagreeing.

3. You do it, with me

There's nothing to install. Read along.

Now open a real merged pull request on a well-known repo. microsoft/vscode or vercel/next.js both work. Read the description. This is the kind of artefact you'll be reading all chapter.

What this chapter refuses to do. It won't tell you to be a team player. It won't tell you to communicate clearly. Those are outcomes, not actions. This chapter teaches the actions.

The shape of every unit. Each unit names one behaviour, gives you a grammar (the literal words to use), and walks a wrong-way / right-way pair drawn from a real repo or thread.

The rules of evidence. Every claim about what "good" looks like has a citation: a real GitHub PR, a real issue, a real maintainer comment. No invented examples for the central rules. When you see a screenshot marker, it points at a real artefact you can click through to.

The assignment frame. The chapter assignment is three open-source PR reviews. You start collecting candidate PRs from unit 27.1 onwards. Bookmark them as you go.

A warning. This chapter will feel boring to some readers. The feeling is the point. These behaviours are unglamorous, and the engineers who reliably do them get the senior title.

Reading pace. Don't binge this chapter. One unit per day for two weeks. The behaviours need to be tried, not just read.

4. What you should be seeing

Three pictures in your head:

1. One unit. Same six beats as every other chapter (or the assignment shape for the final unit).
2. One chapter. Fifteen content units, then one assignment that you submit to yourself.
3. The frame. Named behaviours with grammars. No personality advice. Every claim cited to a real artefact.

If you can state the frame in one sentence, you're done with this unit.

5. Common stumbles

• You expect motivational content and skip the unit. The unit is short on purpose to land the frame before you tune out. Read it once, slowly.
• You try to apply every behaviour at once. Pick one per unit, apply it for a week, then move on. Trying fifteen behaviours at once means doing none of them.
• You read the chapter without trying any of the moves. The grammars only land when you've typed them in a real Slack thread or a real PR comment. The reading alone isn't enough.
