The skill activates automatically when you discuss product decisions, business strategy, growth, pricing, or any product/business topic.

persona-sim

Simulate feedback from census-grounded virtual populations. Panel-score your product / copy / pricing, predict votes with IPF post-stratification, or run what-if social-sandbox experiments — before paying for real user research. Backed by NVIDIA Nemotron-Personas (1M US Census-aligned synthetic people) and methodology from Park et al. 2024.

Features: - 4 skills in one plugin: persona-sim (core engine) + product-feedback-sim (SGO A/B ranking) + vote-predict (policy/voting with IPF) + social-sandbox (what-if experiments) - SGO (Semantic Gradient Optimization) with anchored counterfactuals — causal attribution, not independent re-scoring - Persuadable-middle identification (score 4-7 only) to avoid wasting LLM calls on extremes - IPF post-stratification to reweight panels to real-population marginals (PUMS-ready) - Bias audit with 4 probe types (framing, acquiescence, order, authority) — flags when the simulation under-represents human biases - 6-suite eval score card (GSS attitudes, Big Five norms, test-retest, diversity, demo-correlation, bias-audit) - HuggingFace streaming — no local dataset download required for MVP - Multi-provider LLM routing: native Anthropic, Anthropic-compatible gateways, OpenAI-compatible gateways

Install:

/plugin install persona-sim@yrzhe-skills

Manual install:

cp -r plugins/persona-sim/skills/persona-sim ~/.claude/skills/
cp -r plugins/persona-sim/skills/product-feedback-sim ~/.claude/skills/
cp -r plugins/persona-sim/skills/vote-predict ~/.claude/skills/
cp -r plugins/persona-sim/skills/social-sandbox ~/.claude/skills/

First-time setup: see plugins/persona-sim/skills/persona-sim/SETUP.md — you need to create ~/.claude/data/personas/config.json (from the provided config.example.json) with your LLM API key, and a venv for Python dependencies.

Usage examples: - "Score this landing page copy with 30 software developers" → auto-triggers product-feedback-sim - "Predict US support for a $22 minimum wage, by age and education" → auto-triggers vote-predict - "If AI copilots got regulated tomorrow, what would developers do?" → auto-triggers social-sandbox - Direct Python use: from persona_sim import sampler, sim_engine

design-distiller

Scrape any website's design system into a structured Design MD + decomposed design tokens. Ships with 55 pre-analyzed brand references (Vercel, Stripe, Linear, Notion, Claude, Figma, Airbnb, Spotify, and more) and an 8-dimension Digest Pool for mix-and-match composition.

Features: - 4-phase pipeline: Scrape → Analyze → Generate → Digest - Multi-tier browser support: Browser Use Cloud / Playwright / Chrome Headless / WebFetch fallback - 9-module Design MD format following awesome-design-md standard - 55 pre-loaded brand references with full design system documentation - 8-dimension Digest Pool (typography, colors, spacing, components, depth, motion, layouts, philosophy) - Compose command: mix-and-match from Digest Pool to generate new design systems - Machine-friendly cross-reference tags for programmatic matching - Confidence tagging: High (CSS var) / Medium (computed) / Low (visual estimate)

Install:

/plugin install design-distiller@yrzhe-skills

Manual install:

cp -r plugins/design-distiller/skills/design-distiller ~/.claude/skills/

Usage:

/design-distiller https://vercel.com              # Full pipeline
/design-distiller compose "Vercel typography + Stripe colors + Linear components"
/design-distiller compare vercel stripe            # Side-by-side comparison
/design-distiller list                             # List all 55 references

seed

Build-in-public activity recorder. A Stop hook mechanically logs every Claude Code turn (user prompt + tools used + full assistant output) to a per-session markdown file. When you're ready to tweet, /seed reads the log and helps you synthesize draft tweets from real evidence — no more "wait, what did I actually do today?"

Features: - Zero-cost Stop hook — mechanical turn capture, no LLM calls, no scoring, zero latency - De-duped by user-prompt uuid (Stop hook fires per-turn, so dedup matters) - Per-session markdown logs with full assistant output + tool summaries - /seed shot — screenshot capture bound to the current session (interactive window-pick OR headless Chrome URL mode) - /seed — Claude reads the log and proposes tweet drafts tied to real evidence (skips routine sessions)

Install:

/plugin install seed@yrzhe-skills

Manual install:

cp -r plugins/seed/skills/seed ~/.claude/skills/seed
chmod +x ~/.claude/skills/seed/scripts/*.py

Hook setup (one-time, see plugins/seed/skills/seed/README.md for full instructions):

cp ~/.claude/skills/seed/hooks/capture-session-seed.sh ~/.claude/hooks/
chmod +x ~/.claude/hooks/capture-session-seed.sh

Then add to ~/.claude/settings.json:

{ "hooks": { "Stop": [{ "matcher": ".*", "hooks": [{ "type": "command", "command": "~/.claude/hooks/capture-session-seed.sh" }] }] } }

Usage:

/seed                                # synthesize current session → tweet drafts
/seed shot                           # interactive window pick
/seed shot localhost:3000            # headless Chrome screenshot
/seed list                           # list all session logs
/seed done                           # archive current session

chef

Cooking assistant for Chinese and Western cuisine — recipes are pulled from real sources, never fabricated. LLMs have no taste buds; specific quantities, timings, and heat levels must come from real recipe data or be fetched live. Ships with 604 pre-fetched recipes as evidence.

Sources (all real): xiachufang, douguo, meishij (下厨房/豆果美食/美食杰 — Chinese), allrecipes, BBC Good Food, Food Network, TheMealDB, Serious Eats, Epicurious, and 10+ others. Zero fabrication — if a source doesn't have it, the agent says "let me fetch it" before answering.

Features: - Hard rule: no data = no answer. Every quantity/technique traceable to a source URL - Chinese cuisines: 川/粤/鲁/苏/闽/浙/湘/徽/家常 - Western cuisines: 意/法/美式/地中海/英伦 + categories (mains/baking/soups/salads/breakfast) - Recipe walkthroughs with ingredients (name + gram weight), steps (timing/heat/key moments), doneness cues, common pitfalls - Ingredient-based suggestions (prioritize recipes covering ≥2 of what you have) - Pairing analysis via local co-occurrence + theory (not vibes) - Nutrition lookup (Open Food Facts) + substitution advice - 604 pre-cached recipes in data/recipes/*.md — search before fetch

Install:

/plugin install chef@yrzhe-skills

Manual install:

cp -r plugins/chef/skills/chef ~/.claude/skills/chef

Usage:

"怎么做西湖醋鱼"            → local search → walkthrough with source URL

"X 和 Y 搭不搭"            → co-occurrence + pairing theory
"how do I make carbonara"   → allrecipes/BBC Good Food lookup
"这菜多少卡路里"            → nutrition from frontmatter or OpenFoodFacts
