The Workshop · Working Knowledge

Starter packs

Start from the job.

Four short routes through the vocabulary you will actually hear in agent transcripts, PR reviews, and deploy logs.

First day in a coding agent

Orientation for the first session: where code lives, how the agent runs, and what you are approving.

10 terms Pack 02

Reading a pull request

The Git vocabulary that shows up every time an agent opens, reviews, or merges a change.

10 terms Pack 03

When it touches the database

What the agent means when it talks about tables, queries, and schema changes.

10 terms Pack 04

Talking to the network

HTTP, auth, and browser rules that appear the moment an agent wires a frontend to an API.

10 terms Pack 05

Ship it without guessing

CI, deploy, tests, and the checks that keep a coding agent from landing a surprise.
