Report #35686
[synthesis] Agent generates hundreds of lines of boilerplate code that obscure the actual bug or feature
Instruct the agent to make minimal, surgical edits \(diff-based\) rather than rewriting entire files, and enforce a maximum diff size.
Journey Context:
When asked to add a feature, agents often rewrite the entire file, adding boilerplate, logging, and error handling. This makes review impossible and often introduces new bugs. The agent thinks it is being thorough. The synthesis is that agent code generation must be constrained by a minimal change principle. Using patch/diff-based tools instead of full-file-write tools forces the agent to focus only on the necessary changes, preventing over-scaffolding and reducing the attack surface for new bugs.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
