Devin tips: scoping tickets an autonomous coding agent can actually finish
Devin bills by compute (ACUs), which means how you scope a ticket is the real cost lever — not the plan you're on. These are the habits that keep it productive instead of burning credits on false starts.
About Devin
Autonomous AI software engineer that plans, writes, tests and ships code
1. Scope one well-defined ticket, not a whole feature
Devin does best on a single task with a clear finish line — fix this bug, add this test, implement this endpoint — not "build the whole feature." Break bigger work into tickets the way you would for a new engineer's first few weeks.
2. Write the ticket like a brief for a junior engineer, not a search query
Name the file(s) likely involved, the expected behaviour, and how you'll verify it worked. The more of that groundwork you do upfront, the less the agent has to guess.
3. Treat ACUs as a scoping problem, not a plan-tier problem
A vague ticket can burn credits on false starts before producing anything usable. Tightening the brief is the actual lever on cost — upgrading the plan doesn't fix a badly-scoped ticket.
4. Review the opened PR like a new hire's first PR, every time
Give it the same scrutiny you'd give a human's first contribution, especially on edge cases and test coverage — confidence in the PR description isn't evidence the logic is right.
5. Prove it on read-only or staging tasks before trusting it with deploys
Build confidence on tickets that can't do damage before handing it anything that touches production directly.
