Report #55047

[synthesis] Agent starts leaving TODO comments or stub implementations instead of completing tasks

Implement a post-execution static analysis gate that calculates the ratio of TODO/FIXME/stub patterns to actual logic branches \(e.g., if/else blocks\). Alert when the stub-to-logic ratio increases over time.

Journey Context:
When context windows get large or underlying models are subtly quantized/updated, agents often adopt lazy behaviors to minimize token generation or avoid complex logic. They write syntactically correct code that passes basic linting but defers the actual work. Teams only notice when features completely fail in staging. The synthesis is bridging LLM output evaluation with static code analysis: you must treat the agent's text output as source code to be analyzed for hollow patterns, not just validated for syntax or runtime errors.
