Anthropic's Opus too confusing, user turns to open-source 'unslop' skill

Anthropic's Opus too confusing, user turns to open-source 'unslop' skill

Key takeaway

  • Anthropic's Opus often produces confusing analogies and jargon.

  • A user found that a community skill called 'unslop' greatly improved clarity.

  • The user will keep using it for Anthropic models.

3 Key Points

  1. What happened

    An AI user reports that Anthropic's Opus model frequently produces bizarre analogies and obscure jargon, forcing them to spend extra time and tokens deciphering its output. They found a fix in a ~1,600-token community skill called 'unslop' from cursor's plugins repo, which significantly improved clarity.

  2. Why it matters

    This highlights a usability problem with advanced LLMs: even capable models can be nearly unusable if their communication style is unclear. The user notes that without such a skill, Opus's output was 'nearly unusable' despite the model being intelligent, suggesting a growing demand for output control.

  3. What to watch

    The user says they'll use the unslop skill with Anthropic models going forward but still prefer other models (5.6-Sol and 5.6-Luna) when given the choice. They also speculate that Anthropic's watermarking of text may be partly to avoid training on their own 'AI slop.'

Context & Analysis

This article is a personal account of struggling with an advanced AI model's communication style, a common pain point for non-technical users. The author, a professional user of Opus, describes multiple instances where the model invented odd metaphors or obscure phrases, forcing them to invest extra effort to understand what it meant. This is not just an isolated annoyance; it directly impacts productivity and trust. The author's solution was a community-built 'unslop' skill that standardizes output to be more direct and less 'AI-slop-like.' The fact that a small (1,600-token) skill can make such a difference suggests that model vendors might improve usability by offering more robust output controls by default. The author also speculates that Anthropic's watermarking may be an attempt to prevent the model from training on its own verbose output, which could be seen as a potential feedback loop that degrades quality over time. This narrative underscores the importance of clarity in AI communication, especially as these tools become more integrated into daily work.

FAQ

What is the 'unslop' skill?
It's a small skill (about 1,600 tokens) from cursor's plugins repo that cuts down on AI slop and extra noise in model output. The user found it to be very effective at making Opus's explanations more comprehensible.
Did the user try other solutions before the unslop skill?
Yes, they tried output styles and ASD-STE100, which helped a little but did not fully solve the problem.
