When using AI for code generation, I kept seeing the same issues: N+1 queries, poor exception handling, Spring pitfalls, and concurrency problems. The output is often almost right, but misses language-specific details.

Instead of iterating prompts, I experimented with pre-loading the model with Java-specific guidelines (JPA, Spring, testing, security) as plain markdown files, so it has domain context upfront.

Curious how others handle language-specific context for code generation tools.
