The Claude Code Loop
Explore, plan, edit, verify - the session loop, and the habit of reading first.
TOPIC 01
Explore First
The agent reads the code before it changes it. Make that the rule, not the exception.
What you'll practice
- Explore Before You Edit — guided · beginner
- Read a Codebase in Ten Minutes — practice · intermediate
A command you'll meet
cat ~/.claude/workflow/explore.mdThe agent is fast and confident, which is exactly why the reading step has to be written down. Open the task below for the full walkthrough.
Hands-On Tasks in This Topic (2)
Explore Before You Edit
Editing before reading produces code that duplicates what already exists. Write the rule that keeps the reading first.
Read a Codebase in Ten Minutes
A fixed routine for understanding an unfamiliar repository. Write the ten minute version of it.
TOPIC 02
Verify the Change
The agent says it is done. The build, the tests and the diff say whether it is.
What you'll practice
- Run the Verification Loop — practice · intermediate
- Make the Agent Review Its Own Diff — challenge · advanced
A command you'll meet
cat ~/.claude/workflow/verify.mdTrust but verify, in that order. Open the task below for the full walkthrough.
Hands-On Tasks in This Topic (2)
Run the Verification Loop
Build, test, read the diff - in that order, every time. Write the loop the team runs before anything merges.
Make the Agent Review Its Own Diff
A second pass over the same diff catches what the first one missed. Write the review prompt and the rules for taking it seriously.
