Learn Devin in 5 minutes.
Devin is an autonomous software agent with its own machine: editor, shell, and browser, working tasks from brief to pull request. The lesson drills writing briefs that survive delegation, reviewing plans and PRs, and judging which tasks to hand over.

Brief it like a contractor, not a copilot
A copilot sits with you; Devin leaves and comes back with finished work. Everything about using it well follows from that one difference: the brief has to stand on its own.
Brief to pull request
You give Devin a task, it proposes a plan, then works in its own environment: reading code, editing, running tests, browsing docs. The output is typically a pull request for you to review, not a suggestion in your editor.
Repeatable procedures
A playbook captures how a recurring kind of task should be done, so the tenth dependency upgrade follows the same steps as the first. Write one when you notice yourself giving the same instructions twice.
What it remembers
Persistent notes about your codebase and conventions that Devin consults across sessions. Kept current, it means each new task starts from context instead of from zero.
What you will do in the lesson
You answer and try things. Nobody demonstrates at you for five minutes.
- Write a brief that stands alone. You'll draft a task description containing the goal, constraints, and how to verify success, then stress-test it against the questions an absent agent can't ask you.
- Judge the plan before the work. Devin plans before executing. You'll review a proposed plan and find the step that reveals the brief was misread, while redirecting is still cheap.
- Interrupt without derailing. Mid-session, you can steer. You'll practice course-correcting an agent that is drifting, and compare it to letting the drift finish.
- Review the PR skeptically. Passing tests are not the same as the intended change. You'll examine a Devin pull request for the gap between what was asked and what was built.
- Build a delegation shortlist. You'll sort a backlog into tasks worth handing to an autonomous agent and tasks where supervision costs more than doing it yourself.
Before you start
Is Devin actually autonomous, or is that marketing?
It genuinely plans and executes multi-step work in its own environment, including running tests and browsing documentation. It is not infallible, and it can pursue a wrong interpretation efficiently, which is precisely why the lesson spends so much time on briefs and plan review. Autonomy raises the stakes on clarity.
Do I need Devin access to take this lesson?
No. The lesson runs free in this page, no account, nothing to install. It teaches the delegation and review skills, which transfer to any autonomous coding agent you end up using.
What kinds of tasks is Devin actually good at today?
Well-bounded work with clear success criteria: targeted bug fixes, dependency upgrades, adding tests, mechanical refactors, small features in an established codebase. Open-ended design work is a poor fit. The narrower the definition of done, the better the results.
I use Cursor's agent already. Is Devin just more of that?
It's the same direction taken further. Cursor's agent works inside your editor with you watching; Devin works remotely on its own machine and delivers a pull request. That means less oversight per minute and more weight on the brief and the review. Many teams use both: editor agents for supervised work, Devin-style sessions for delegation.
