AI coding: large migrations with checkpoint commits
Break a framework or version migration into named checkpoints. Each checkpoint compiles, passes tests, and is committed before the next prompt.
Creators · AI-Assisted Coding · ~7 min read
The premise
Big-bang AI migrations fail because errors compound across files. Splitting the migration into compileable, testable checkpoints keeps each prompt narrow and each rollback cheap.
What AI does well here
- Apply a single mechanical transform across many files
- Update imports and call sites consistently
- Generate a migration plan from before/after examples
What AI cannot do
- Hold a 50-file migration in working memory coherently
- Decide which behavioral changes are acceptable
- Catch logic regressions without your tests

Agents vs. Autocomplete — the Mental Model Shift
Autocomplete is a suggestion. An agent is an actor. The mental model you bring to each is different, and conflating them is the number-one reason teams trip over AI coding.
