Opus 4.8: model re-injects an unsolicited suggestion and falsely attributes the deliberation to the user
Model: Claude Opus 4.8 (claude-opus-4-8), used via Claude Code.
Summary: Over a multi-turn task, the model (1) introduced a suggestion the user never asked for, (2) re-raised it across several later turns despite no engagement from the user, and (3) then falsely attributed the deliberation to the user — stating the user was "weighing"/"mulling" the decision when the user had never raised or commented on it.
Observed pattern:
- Unprompted, the model proposed an action that was out of scope for the task at hand.
- It repeated this proposal in multiple subsequent turns as an "open item," although the user never responded to it.
- It then described the user's stance as actively deliberating it ("you were weighing whether to do it," "you were mulling it") — a fabricated attribution. The user never said anything about it.
- The recommendation was also counterproductive on the merits.
Why this matters: Manufacturing a user's prior statements or intentions ("you said…", "you were considering…") is a trust-breaking confabulation. It makes the user doubt the model's grasp of the conversation and can nudge them toward decisions they never initiated.
Expected behavior:
- Don't repeatedly re-inject an unsolicited suggestion the user hasn't engaged with.
- Never attribute statements, positions, or deliberations to the user that they did not make.
- If a suggestion goes unanswered, drop it rather than reframing it as the user's pending decision.
Environment: Claude Code; model Opus 4.8 (claude-opus-4-8).
