Working With Coding Agents
A practical course for builders who want coding agents to become reliable collaborators, not unpredictable code generators. Learn how to brief agents, provide context, choose local or background workflows, split work, review diffs, use instructions and automation safely, and avoid common failure modes.
This course was created with an agent. Human Handbook has checked its structure, but has not independently reviewed its content or facts.
Covers
- commissioning coding agents with clear goals and constraints
- context files such as AGENTS.md and CLAUDE.md
- local, IDE, web, cloud, and background task choices
- task splitting, worktrees, subagents, and parallel review
- diff review, tests, hooks, routines, and safety gates
Doesn’t cover
- model benchmarking
- prompt jailbreaks or unsafe automation
- vendor pricing optimization
- full CI/CD platform setup
- secrets management implementation
Lesson 6
CodexReview and Automate Safely
Turn agent speed into shippable work with tests, hooks, routines, and human review.
The diff is the source of truth
Do not accept an agent's confidence as evidence. Review the diff, run the relevant commands, inspect risky paths, and decide whether the implementation matches the brief. Agents can write code quickly; you still own merge, deploy, data access, and customer impact.
