feat: Add generator skills category + create-agent-tui skill

[jonisjongithub]

Summary

This PR expands the Venice skills repo to support two types of skills:

1. API Documentation Skills (existing, venice-*)

• Teach agents how to use specific Venice API endpoints
• Follow the strict endpoint/curl/errors template
• Examples: venice-chat, venice-embeddings, venice-audio-speech

2. Generator / Scaffolding Skills (new, create-*)

• Help agents create new projects using Venice AI
• Include sample code, references, and interactive checklists
• More flexible structure, focused on project generation workflows

---

Changes

README.md

• Split skill catalog into two sections:
  • API Documentation Skills (existing)
  • Generator / Scaffolding Skills (new)

CONTRIBUTING.md

• Added "Skill types" section explaining both categories
• Added "Style for Generator Skills" guidelines
• Added separate review checklists for each type

New Skill: create-agent-tui

A skill for AI coding agents (Claude Code, Cursor, Codex) that scaffolds complete agent TUI projects targeting Venice AI.

Like create-react-app but for terminal agents.

Inspired by OpenRouter's create-agent-tui skill, but built specifically for Venice with additional features:

Venice-Specific Features

• 🔍 Web search integration (--web-search auto|on|off)
• 🐦 X/Twitter search (Grok models only)
• 🧠 Reasoning effort control (6 levels)
• 🎫 DIEM cost tracking support
• ⚡ Model aliases (opus, sonnet, grok, deepseek, llama, etc.)
• 🔐 Privacy-first with Venice's zero-retention API

TUI Features

• 7 built-in tools (file read/write/edit, shell, grep, glob, list-dir)
• 4 tool display styles (grouped, emoji, minimal, hidden)
• 3 loader animations (spinner, gradient, minimal)
• 3 input styles (block, bordered, plain)
• ASCII banner generator with Venice logo option
• JSONL session persistence with Markdown export

Testing

• Sample compiles cleanly (npx tsc --noEmit)
• All tools tested locally
• Streaming works with Venice API
• Session persistence creates valid JSONL

Quick Start

cd skills/create-agent-tui/sample
npm install
VENICE_API_KEY=vn_xxx npm start -- --model grok --banner venice
