Hashimoto flags 1500-line agent diffs for decomposition
Mitchell Hashimoto discusses his approach to working with coding agents on feature work, noting that if an agent generates a diff larger than 1500 lines, it signals the problem is too large and should be broken down. His pattern involves first attempting the entire feature with a loose "draw the owl" prompt before decomposing the task.
// ANALYSIS
This heuristic provides practical guidance for developers integrating AI agents into their workflows, highlighting current limitations in handling large contexts and complex tasks.
- –A 1500-line diff limit serves as a concrete benchmark for knowing when to intervene and split tasks.
- –The "draw the owl" initial pass allows the agent to attempt the whole task before manual decomposition is required.
- –Emphasizes the ongoing need for human oversight and strategic problem breakdown in AI-assisted development.
