    {
      "question": "Is a thumbs-up rate a good measure of AI agent quality?",
      "answer": "A thumbs-up rate is a weak measure of AI agent quality on its own, because only a small, self-selected share of users ever click, and they skew toward strong reactions. Use it as one signal to route traces to review, and pair it with implicit signals and sampled human judgment."
    },
    {
      "question": "What implicit signals show that an AI agent failed?",
      "answer": "Common implicit failure signals are a user re-asking the same question, correcting the agent, abandoning the session, or escalating to a human. Each is ambiguous on its own, so treat them as candidates for review and confirm against the trace before calling any of them a failure."
    },
    {
      "question": "How do I connect user feedback to the agent run that caused it?",
      "answer": "Store the trace ID of the run on the same record as the feedback event, at the moment the response is shown to the user. A rating that arrives later with no trace ID cannot be joined back to spans, tool calls or retrieved context, so it cannot be diagnosed."
    },
    {
      "question": "Can live feedback replace offline evaluation for an AI agent?",
      "answer": "Live feedback cannot replace offline evaluation, because the two answer different questions. Offline evaluation gates a release against a fixed set, while online signals catch drift and unanticipated inputs afterward, which is the split the evaluating-ai-agents resource draws."
    }
  ],
  "body": "Live user feedback measures AI agent quality only when each signal is tied to the trace of the run that earned it, and only when its bias is understood before it is trusted. [The pillar](/articles/agent-observability-and-evaluation) lists the signal types in its online-metrics section; this article is about whether those signals are good enough to act on. The design below is this article's own reasoning as of 2 October 2026, not a published standard.\n\n## Why is explicit feedback a biased sample?\n\nExplicit feedback is biased because the users who click a rating are a self-selected minority, so a thumbs-up share describes them and not your traffic. Two effects compound. Most users never rate anything, which leaves the sample sparse. Those who do tend to react to something notable, a clearly wrong answer or an unusually good one, so the middle of the distribution is underrepresented.\n\nNone of the reference resources gives a response-rate figure for feedback widgets, and this article does not invent one. Treat any number from your own widget as a measurement of that widget:\n\n- **Sparsity:** a quiet week can contain too few ratings to compare against the previous one. Check the count before the ratio.\n- **Placement bias:** where the control sits and when it appears changes who uses it. Moving it changes your metric even if the agent did not change.\n- **Direction bias:** a rating records a reaction, and does not explain it. A thumbs-down can mean a wrong answer, a slow one, or a refusal the user disliked.\n\nUsed honestly, explicit feedback is a cheap way to find traces worth reading, not a quality score.\n\n## Which implicit signals indicate a failed interaction?\n\nFour implicit signals are usually proposed as failure indicators: a re-ask, a user correction, abandonment, and escalation. All four are ambiguous, and the right way to hold them is as hypotheses a trace can confirm.\n\n| Signal | Possible failure reading | Benign reading |\n|---|---|---|\n| Re-ask of the same question | The first answer missed | The user is exploring or refining |\n| User correction | The agent was wrong | The user changed their mind |\n| Session abandonment | The agent gave up or looped | The user got the answer and left |\n| Escalation to a human | The agent could not help | A policy-required handoff worked as designed |\n\nThe [customer-support-agents resource](/resources/customer-support-agents) makes the same point for deflection rate: a contact resolved without a human can look identical to a customer who gave up. It recommends pairing deflection with a resolution-quality signal, such as explicit customer confirmation, a no-repeat-contact window or a post-resolution survey. The [voice-realtime-agents resource](/resources/voice-realtime-agents) names containment rate among the production signals monitored online. It describes online monitoring as catching drift an offline set misses, and does not claim containment equals quality.\n\n## Is escalation share a quality metric?\n\nEscalation share is a useful drift indicator but not a quality metric, because a handoff can be the correct outcome. The pillar says that no reference resource defines an \"escalation rate\" or gives a threshold, and that remains true as of October 2026. A rising share is worth investigating, and the investigation has to separate designed handoffs from failures.\n\nThe customer-support-agents resource says escalation should fire on explicit, enumerable conditions, not on the model's own sense of uncertainty. That gives a way to split the numerator: log the trigger that caused each escalation. An increase in policy-boundary escalations after a policy change is expected. An increase in escalations with no matching trigger deserves a trace review. Set your own baseline from your own traffic, with no external number.\n\n## How do you join a signal to the run that caused it?\n\nJoin a signal to its run by writing the trace ID onto the feedback record when the response is displayed, not when the feedback arrives. The [agent-observability resource](/resources/agent-observability) defines a trace as one complete run under a stable trace ID, with each model call, tool invocation and retrieval stored as a span, and notes that traces are the raw material for both offline evaluation and online monitoring. A signal without that ID is a number that cannot be explained.\n\nJoin integrity fails in a few predictable ways:\n\n- **Late binding:** the client sends feedback with a session ID only, and the server guesses which run it meant. In a multi-turn session the guess can be wrong.\n- **Retries and regenerations:** a user rates the second answer, but the record points at the first.\n- **Handoffs:** the rated answer was assembled by a sub-agent, so the visible trace ID must propagate. See [multi-agent trace propagation](/articles/multi-agent-trace-propagation) for how the ID survives a handoff.\n\nOnce the join holds, the useful question is which context produced the rated answer. The span fields that answer it, such as what a retrieval step returned and what reached the context window, are covered in [how to log RAG retrieval in production](/articles/retrieval-attribution-logging-in-production). Do not rebuild that schema for feedback. Store the trace ID, the rating or behavior, and a timestamp, and let the trace carry the rest.\n\n## How should signals feed a review queue?\n\nSignals should work as routing keys that decide which traces a human or a judge reads, not as inputs to a single blended quality score. A flagged trace, meaning a thumbs-down, a re-ask or an unexplained escalation, enters a queue, and the review result is the quality measurement.\n\n[The judge-screening article](/articles/llm-as-judge-screening-in-production) covers how a judge and a human queue divide the work and how stakes should route a flag. The only addition here is the source: a user signal is a second way to nominate a trace, alongside sampling. It is also a biased nomination, as described above, so keep a random sample in the mix to measure what the signals miss.\n\nA queue entry needs only a few fields: trace ID, which signal flagged it, the time, and a status. Record the reviewer's verdict next to the signal, and you can later check which signals predicted real failures in your own traffic. That comparison is the only honest way to learn which signals deserve weight, and it is a measurement you must run yourself.\n\n## When does a flagged trace become a fixture candidate?\n\nA flagged trace becomes a fixture candidate once a reviewer confirms the agent was wrong and the failing decision can be isolated. Signals nominate, review confirms, and only then does the conversion start. The conversion itself, freezing, redacting, minimizing and proving the test red then green, is in [turning an incident into a test case](/articles/incident-to-eval-fixture-loop).\n\nUser-flagged traces carry one extra caution: user-supplied text can contain personal data, so the redaction step matters more here than for an internal incident.\n\n## How do online signals relate to offline evaluation?\n\nOnline signals and offline evaluation are complementary, and neither substitutes for the other. The [evaluating-ai-agents resource](/resources/evaluating-ai-agents) says offline evaluation runs against a fixed dataset and is fast, reproducible and cheap, while online evaluation on real user interactions detects shifts in inputs and benchmark contamination, at the price of being less repeatable. The voice-realtime-agents resource states the division as: use offline evaluation to gate a release, and online monitoring to catch what it misses afterward.\n\nIn practice the loop runs one way. Live signals surface failures the fixed set did not contain, review confirms some, and confirmed cases join the suite described in [evaluating AI agents in CI](/articles/evaluating-ai-agents-in-ci). An online metric therefore does not gate a release by itself. Its job is to feed the gate.\n\n## What does ChangeGamer itself collect?\n\nChangeGamer collects no user feedback at all, so it has no first-hand feedback signals to report. Its Cloudflare Worker function `logAccess` in `worker/index.ts` writes four fields to Analytics Engine for each access event: category, slug, outcome and the user-agent truncated with `ua.slice(0, 100)`. It is a no-op when the binding is absent. As far as the repository shows, no endpoint accepts a rating, correction or any other user feedback, which means the site's access log is a fetch log, not a quality signal.\n\nThat is a deliberate limit of this article. Everything above about signal quality is reasoned from the corpus resources and general practice, not from a ChangeGamer deployment. Verify each point against your own traffic before relying on it.",
