Report #83611
[synthesis] LLM-generated code has subtle bugs that compound across agent turns — where does verification fit in the architecture?
Couple verification directly into the agent loop as a mandatory post-action step, not as a separate user-triggered process. After every code-generating action, automatically run type checking, linting, tests, or a preview render. Feed the verification output back into the agent's next observation. The loop is: generate→verify→observe results→fix if needed→verify again.
Journey Context:
Many tutorials show the agent loop as think→act→observe, where 'observe' means reading the tool output. But for code agents, the tool output \(e.g., 'file written successfully'\) is insufficient — the code may compile but be wrong. Devin's demo shows it running tests after changes and reading the test output. v0 renders a live preview after generation and the user \(or system\) can spot visual errors. Cursor's terminal integration surfaces lint and type-check output in real time. The synthesis: verification is not a QA afterthought, it is the observation step. Without it, the agent is flying blind — it knows it wrote something but not whether it works. Architecturally, this means every mutating action must have a corresponding verification action in the same turn.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
