Improve LLM API Test Suite (#38)

* Update README.md (#34)

* [Cursor] Improve test handling of LLM API configurations

- Add test_utils.py with smart detection of unconfigured/example API keys
- Add graceful error handling for API failures in live tests
- Consolidate test assertions into helper method
- Update README to document verbose test output
- Clean up duplicate code in test files

This improves the testing experience by:
1. Skipping tests when API keys are missing or using example values
2. Converting API errors to skipped tests rather than failures
3. Providing clear messages about why tests were skipped
4. Making test output more informative with -v flag

-# Devin.cursorrules
+# Transform your $20 Cursor into a Devin-like AI Assistant
 
-Transform your $20 Cursor/Windsurf into a Devin-like experience in one minute! This repository contains configuration files and tools that enhance your Cursor or Windsurf IDE with advanced agentic AI capabilities similar to Devin, including:
+This repository gives you everything needed to supercharge your Cursor or Windsurf IDE with **advanced** agentic AI capabilities — similar to the $500/month Devin—but at a fraction of the cost. In under a minute, you'll gain:
 
-- Process planning and self-evolution
-- Extended tool usage (web browsing, search, LLM-powered analysis)
-- Automated execution (for Windsurf in Docker containers)
+* Automated planning and self-evolution, so your AI "thinks before it acts" and learns from mistakes
+* Extended tool usage, including web browsing, search engine queries, and LLM-driven text/image analysis
+* [Experimental] Multi-agent collaboration, with o1 doing the planning, and regular Claude/GPT-4o doing the execution.
 
+## Why This Matters
+
+Devin impressed many by acting like an intern who writes its own plan, updates that plan as it progresses, and even evolves based on your feedback. But you don't need Devin's $500/month subscription to get most of that functionality. By customizing the .cursorrules file, plus a few Python scripts, you'll unlock the same advanced features inside Cursor.
+
+## Key Highlights
+
+1.	Easy Setup
+   
+   Copy the provided config files into your project folder. Cursor users only need the .cursorrules file. It takes about a minute, and you'll see the difference immediately.
+
+2.	Planner-Executor Multi-Agent (Experimental)
+
+   Our new [multi-agent branch](https://github.com/grapeot/devin.cursorrules/tree/multi-agent) introduces a high-level Planner (powered by o1) that coordinates complex tasks, and an Executor (powered by Claude/GPT) that implements step-by-step actions. This two-agent approach drastically improves solution quality, cross-checking, and iteration speed.
+
+3.	Extended Toolset
+
+   Includes:
+   
+   * Web scraping (Playwright)
+   * Search engine integration (DuckDuckGo)
+   * LLM-powered analysis
+
+   The AI automatically decides how and when to use them (just like Devin).
+
+4.	Self-Evolution
+
+   Whenever you correct the AI, it can update its "lessons learned" in .cursorrules. Over time, it accumulates project-specific knowledge and gets smarter with each iteration. It makes AI a coachable and coach-worthy partner.
+
