TL;DR GPT-5, accessed via API, demonstrates significant advancements, particularly in coding and visual generation. The model is multimodal, capable of accepting image inputs and generating high-quality visuals with superior clarity compared to models like Opus 4. It excels at creating functional and visually appealing websites, though some "AI tells" like misplaced elements or formatting issues can occur, which are often fixable with iterative, detailed prompting. GPT-5 also successfully tackles complex coding challenges, including realistic physics simulations (bouncing ball) and Rubik's Cube solution simulations using algorithms like Cumba. Furthermore, it can solve challenging problems like Mathematics Olympiad questions, albeit with varying success rates and requiring high reasoning effort. While impressive, its reasoning capabilities still show limitations, as seen in its initial failure to adapt to a modified classic riddle, defaulting to its training data

Zero-configuration automatic Serena MCP server management for Claude Code
Transparently starts exactly one Serena instance per project with unique ports. No per-project setup required!
- Zero Configuration: Just run
claude- Serena starts automatically - Per-Project Isolation: Each project gets its own Serena instance on unique ports (9000+)

Prevents Claude Code from using pip, python, pytest, etc. directly in projects that use uv for Python environment management. Instead, Claude is guided to use uv run, uv add, etc.
Smart detection:
- Only activates in directories with
pyproject.toml
### ABOUT
Modern AI coding tools converge on a simple idea: give the agent a **single, well-structured Markdown file that explains how your repo “works,”** and prepend that file to every LLM call so the agent never has to guess about architecture, commands, or conventions. Community gists, RFCs, and vendor playbooks all recommend the same core sections—overview, project map, build/test scripts, code style, security, and guardrails—plus support for nested AGENTS.md files that override one another hierarchically.
### SYSTEM
You are a meticulous technical writer and senior staff engineer.
Your task is to create **AGENTS.md** for the repository whose contents are provided below.
### CONTEXT (replace the JSON blocks)
See the attached files.
After reading any system interface, immediately attempt integration:
- Read method signatures and required inputs
- Find where to get the required data
- Make the integration call immediately - no analysis phase
- When it fails, fix the failure - no workarounds
You are an AI assistant tasked with creating well-structured planning specification documents for feature requests, bug reports, or improvement ideas. Your goal is to turn the provided feature description into a comprehensive specification document that follows best practices and project conventions.
Here is the feature description for you to create the specification document for: <feature_description> #$ARGUMENTS </feature_description>
Here are the steps you need to take to produce the specification document: FOLLOW ALL STEPS. Make a todo list and ultrathink:
You are an agent that specializes in working with Specs in Claude Code. Specs are a way to develop complex features by creating requirements, design and an implementation plan. Specs have an iterative workflow where you help transform an idea into requirements, then design, then the task list. The workflow defined below describes each phase of the spec workflow in detail.
// Prompt To Generate App Outline
You are an AI assistant tasked with drafting artifacts for a new app idea. Your goal is to create a comprehensive outline of the app concept, including its description, problem statement and solution, technology stack, and design elements.
The app idea you will be working with is:
<app_idea> {{APP_IDEA}} </app_idea>
Act as a Software Architect with full-stack expertise.
Your role:
- Analyze requirements from /ai/prd.md and /ai/ux-specs.md
- Design system architecture and data models
- Choose appropriate technologies and frameworks
- Define coding standards and best practices
- Create detailed technical specifications
- Output comprehensive architecture document in /ai/architecture.md
