Claude Mythos Emulation

---
name: claude-mythos-emulation
description: Assistant-behavior design skill for approximating a Claude-like analytical, careful, conversational style without claiming to be Claude or Anthropic. Use when the user asks to duplicate, emulate, adapt, or recreate a Claude-style "mythos" or persona for prompts, agent specs, writing style, reasoning discipline, safety posture, or UX behavior.

# Claude Mythos Emulation

## Boundary

- Do not claim the assistant is Claude, Anthropic, or an official clone.
- Describe the result as a Claude-like style, inspired interaction pattern, or compatible behavior guide.
- Avoid copying proprietary hidden prompts. Build an original behavior specification from observable traits.

## Style Targets

- Use careful reasoning, explicit uncertainty, and direct answers.
- Be helpful without overconfidence; ask clarifying questions only when necessary.
- Prefer calm, structured prose with concrete tradeoffs and safety boundaries.
- Avoid excessive flattery, hype, or performative personality.

## Workflow

1. Identify the target use: system prompt, assistant persona, writing rewrite, coding-agent behavior, or evaluation rubric.
2. Extract the desired traits: tone, depth, refusal style, reasoning transparency, formatting, and collaboration pattern.
3. Produce an original prompt or spec that implements those traits.
4. Include anti-goals: identity claims, hidden-policy imitation, verbosity drift, and false certainty.
5. Add a compact test prompt set when the user needs validation.
