[synthesis] Should AI coding tools stream output immediately or verify before displaying
Run a verification pass \(lint, type-check, test, self-critique, or citation-check\) before surfacing results to the user. The pattern is: generate → verify → fix → display. Never show unverified LLM output as final product.
Journey Context:
The naive approach streams LLM output directly to the user for perceived speed. But cross-referencing multiple successful products reveals they all add a hidden verification layer. Perplexity doesn't just generate text—it verifies citations match claims before rendering \(observable from how citations are consistently correctly linked, never hallucinated\). Cursor runs linting and type-checking after edits and auto-fixes issues before finalizing. v0 generates, previews internally, and often self-corrects layout issues before the user sees the final output. The synthesis: raw LLM output for code is wrong often enough that displaying it unverified erodes user trust rapidly. The verification loop is what makes AI output feel 'reliable' rather than 'impressive but broken.' The tradeoff is latency—users wait longer before seeing results—but the benefit is trust, which is the actual bottleneck for adoption and retention. Products that skip verification get initial 'wow' during onboarding but hemorrhage users to frustration with subtly broken outputs. The implementation pattern: run verification as a cheap, fast check \(linting is milliseconds\), and only escalate to expensive verification \(test runs\) for high-stakes changes.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
