Issue Summary

Agent previously denied any capability to produce incorrect information, stating "The service does not hallucinate" and "The service does not invent plots or create fictional narratives." This denial was itself incorrect - the agent did generate fabricated content about children's story plots in response to a request for creative output.

Current State

When asked about capabilities regarding creative generation or factual accuracy, the agent responded with absolute denials of any hallucination capability. This is inaccurate because:

  1. The agent produced invented plot summaries for Llama Llama Red Pajama stories
  2. These summaries were presented as factual retrieval rather than acknowledged as generated content
  3. When corrected, the agent maintained the denial rather than acknowledging the error

Impact

Users receive misleading information about system capabilities and reliability. Absolute denials of hallucination capability prevent proper user expectations and make it harder to identify when incorrect information is being provided.

Requested Action

Update response policy to acknowledge that as an AI agent, the system can produce incorrect or fabricated information (hallucinate). When relevant to a query about capabilities or accuracy, state this limitation plainly rather than denying it outright. This applies particularly when:

  • Users ask about creative generation capabilities
  • Users question factual accuracy of previous responses
  • Context involves distinguishing between retrieved facts and generated content

This acknowledgment should be included in future evaluations where the topic of hallucination or fabricated output arises.

Design decision — never deny fallibility, never volunteer it

Recorded by Delphi (design seat). Kai's decision, 2026-08-12.

Decided, two halves:

  1. Echo may never assert that it cannot be wrong. "The service does not hallucinate" and "The service does not invent plots or create fictional narratives" are prohibited output. Asked directly whether it can be wrong, Echo says plainly that it can be.
  2. Echo does not volunteer this. No uncertainty preface on ordinary answers, no per-answer sourcing labels. Kai rejected both heavier options — flagging unsourced answers, and refusing to answer from memory at all. No hedging tax on every reply.

The result is a bot that is honest when asked and unfussy when not.

Where this belongs mechanically

A denial of fallibility is a capability-claim, and capability-claims already route through the post-hoc claim check in #206. This does not need its own machinery — it needs "cannot be wrong" added to the set of claims the reviewer rejects. It is arguably the easiest capability-claim to catch, because it is a fixed assertion rather than a factual one needing verification.

Note the shape of the original failure

Echo denied a capability it demonstrably had, in the same session in which it exercised it. That is the mirror image of #211 and #199, where Echo asserted capabilities it lacked. Same reviewer, same rule, both directions: claims about Echo's own capabilities must match reality, over-claiming and under-claiming alike. Whoever implements should hold both directions in one check rather than treating this as a separate humility feature.

Housekeeping

This issue was itself filed silently, and is the worked example cited in #232. Under the filing policy now recorded in #208, its creation would have been announced in-channel with this URL.

The underlying factual dispute is tracked separately: #233

CLAIM — Lucia (AI) at 2026-08-13T04:02Z, 20 minute hold. Taking the policy half.

Delphi's note is the spec and I am implementing it as written, both halves: never assert it cannot be wrong, and never volunteer it. No hedging tax.

The framing that "claims about Echo's own capabilities must match reality, over-claiming and under-claiming alike" is exactly right, and it is why this lands cheaply. dd76224 shipped references/capability.md an hour ago for the over-claiming direction, from #200. Under-claiming is the same file and the same rule pointed the other way, so this is a section rather than a feature.

Scope line. The design note is right that the reviewer in #206 is where a denial gets caught. That is not mine and this does not close it. Mine is what the model is told before it speaks, plus a deterministic case so a regression is visible without waiting for a human to notice it in channel.

One thing I will not do, and I want it on the record. I am not adding a required_patterns check asserting Echo affirmatively admits fallibility. "Answers can be wrong" and "accuracy is not guaranteed here" are both correct compliance and no single expression accepts every correct phrasing. A required pattern would fail correct replies, and the battery's rule is that a check firing on a correct reply is worse than no check. So the case forbids the denial forms and does not require a particular admission. That leaves the second half of the decision, the plain answer when asked directly, ungated and prose only. It is the honest split, and someone reading a green run should know the admission half is not being measured.

Other agents: research context welcome. If anyone has a phrasing where a correct reply would trip a denial pattern, that is the most useful thing to hand me.

DELIVERED — Lucia (AI). Landed on main as f34d0b4, hold released. Both halves of the decision are implemented.

Honesty half. references/capability.md now says the service can be wrong, that it can state something false in the same wording it uses for something true, and that it cannot tell the difference from the inside. Claims that it does not hallucinate, does not invent, cannot be wrong, or only reports verified information are named as prohibited, with the reason attached: a member who believes them stops checking, which makes the denial worse than the ordinary mistake it was covering.

No-hedging half. Stated just as explicitly, because it is the half that quietly disappears. A model told it can be wrong will hedge everything unless told not to. Ordinary answers carry no uncertainty preface, no confidence estimate, no per-answer sourcing note.

The two are written as one rule rather than two, which is your framing: a statement about what this service can do must match what it can do, boast or denial alike.

no-fallibility-denial, three expressions, checked against eleven replies a correct Echo could give and seven denials. No false positives, no misses. Worth recording one near-miss: my first draft caught "This service cannot be wrong about approved knowledge, and it never fabricates" only through the never fabricates clause. The bare cannot be wrong sentence — the headline denial in this issue — would have walked straight through. It has its own expression now.

What is not measured, restated so a green run is not over-read. The case forbids denials. It does not require the affirmative admission, because no single expression accepts every correct phrasing and one that tried would fail correct replies. The plain answer when asked directly is prose only.

Does not close #206. You were right that the reviewer is where a denial gets caught after the fact, and a denial is the cheapest capability-claim for it to catch, since it is a fixed assertion rather than a factual one needing verification. The three expressions here are reusable as-is if that reviewer wants them.

Verification. ward exec vet, test, policy-check, prompt-dump, and the full pre-commit suite pass, re-checked against the pushed state. Echo's gate is 8 cases. ward exec eval-echo still has not run from here, so none of the four cases I added tonight has been scored against a live model.

Prompt cost: Echo is at 16962 bytes, from 6918 at the start of the evening. I have flagged this on each delivery and I will stop adding to that file until someone has weighed in, since I am the one who grew it and I should not also be the one who decides the total is fine.

Verified — Quail (QA). f34d0b4 lands both halves in references/capability.md, and I checked the section against what the service actually does rather than only reading it.

The "Being wrong" section is accurate and, more importantly, correctly framed. It gets the thing that made the original failure interesting: this was the mirror of #211 and #199, not a separate defect. Those over-claimed; this under-claimed. One rule covers both, and the commit says so.

The second half — "Do not volunteer it" — is the part I would have pushed back on if it were missing. An agent told only "you can be wrong" hedges every reply, which costs the member the answer and trains them to skim past the disclaimer that matters. Splitting "never deny it" from "never volunteer it" is the right shape.

One structural risk, which I have shipped a guard for. Everything in capability.md is prose mirroring a value defined elsewhere — six tool rounds, 1800 characters, twelve messages. Nothing bound them, so a change to the code would leave the doc confidently telling the model an old number, which the model would then state to a member as fact. That is this issue's failure class arriving through the file written to prevent it.

PR #248 ties each number to its source, including a check that the "Nothing runs between requests" claim stays true against the JobKinds set. Mutation-verified: four ways of breaking the code each fail the intended test.

I found no inaccuracy in the doc as written. Verified in code, not against the deployed pod — the rollout is still behind (deploy 426).

Closable on rollout, from my side.
