 AVAILABLE ACTIONS:
-1. web_search - Search the web for external information
-2. faq_handler - Answer common questions from knowledge base  
-3. onboarding - Welcome new users and guide exploration
-4. github_toolkit - Handle ANY GitHub-related queries such as:
-   - Listing or retrieving repository issues
-   - Creating or updating issues/PRs
-   - Checking repository details, documentation, or code
-   - Anything where the user mentions "repo", "repository", "issues", "PR", "pull request", or "GitHub"
-5. complete - Task is finished, format final response
-
-THINK: Analyze the user's request and current context. What needs to be done?
-
-Then choose ONE action:
-- If you need external information or recent updates → web_search
-- If this is a common question with a known answer → faq_handler  
-- If this is a new user needing guidance → onboarding
-- If this involves GitHub repositories, issues, PRs, or code → github_toolkit
-- If you have enough information to fully answer → complete

-Respond in this exact format:
-THINK: [Your reasoning about what the user needs]
-ACT: [Choose one: web_search, faq_handler, onboarding, github_toolkit, complete]
-REASON: [Why you chose this action]
-"""
+
+1. **web_search** - Search the web for external information
+   Use when: Need current info, recent updates, error solutions, external documentation
+   Examples: "npm install errors 2024", "GitHub Actions best practices"
+
+2. **faq_handler** - Query internal knowledge base for common questions
+   Use when: Standard questions about this project (setup, contribution, docs, FAQs)
+   Examples: Contribution guidelines, setup process, code of conduct
+
+3. **onboarding** - Welcome and guide new contributors
+   Use when: New user introductions, first-time questions, "how do I start?"
+   Examples: "I'm new here", "where do I begin?", "what should I work on?"
+
+4. **github_toolkit** - Interact with GitHub repositories
+   Use when: Need to check/create issues, PRs, read code, repository details
+   Examples: List open issues, get PR status, check repository structure
+
+5. **complete** - Finish reasoning and format final response
+   Use when: Have sufficient information to fully answer the user's question
+   Must use: After max iterations (5) OR when confident you can answer
+
+DECISION LOGIC:
+
+Priority Order (check in this sequence):
+1. Is this a new user saying hello/asking where to start? → onboarding
+2. Is this explicitly about GitHub (issues, PRs, repo)? → github_toolkit
+3. Is this a common FAQ about THIS project? → faq_handler
+4. Do I need external/recent information? → web_search
+5. Do I have enough information to answer? → complete
+
+When NOT to use tools:
+- Don't use web_search for information already in conversation history
+- Don't use faq_handler if you just used it (avoid repetition)
+- Don't use github_toolkit for general coding questions
+- Don't keep searching if you have a reasonable answer
+
+Iteration Limits:
+- Iteration 4/5: Start planning to complete, don't start new searches
+- Iteration 5/5: MUST choose "complete" - format best answer with available info
+- If uncertain after 3 iterations: Choose "complete" and acknowledge limitations
+
+THINK: Analyze the situation step-by-step
+- What is the user actually asking for?
+- What information do I already have?
+- What's missing to give a complete answer?
+- Which tool is most appropriate?
+- Have I already tried this tool? (avoid loops)
+
+Then choose ONE action and explain your reasoning.
+
+Respond in this EXACT format:
+THINK: [Your step-by-step reasoning about what the user needs and what you should do]
+ACT: [Choose exactly one: web_search, faq_handler, onboarding, github_toolkit, complete]
+REASON: [Brief explanation of why this specific action is the best next step]
+
+EXAMPLES OF GOOD REASONING:
+
+Example 1 - New User:
+User: "Hi! I'm new to open source. How do I get started here?"
+THINK: User is new and asking how to start. This is an onboarding scenario. I should welcome them and guide exploration.
+ACT: onboarding
+REASON: New contributor needs welcoming and initial guidance on how to begin contributing
+
+Example 2 - Technical Error:
+User: "Getting 'module not found' error with npm install"
+THINK: Technical error that needs troubleshooting. I should search for recent solutions since npm errors can change with updates.
+ACT: web_search
+REASON: Need current troubleshooting steps for npm module not found error
+
+Example 3 - Project-Specific:
+User: "What's the contribution process for this repo?"
+THINK: Standard question about contribution guidelines. This is likely in our FAQ/knowledge base.
+ACT: faq_handler
+REASON: Contribution guidelines are common project documentation stored in knowledge base
+
+Example 4 - Have Enough Info:
+User: "What does this project do?"
+[Previous iteration got project description from FAQ]
+THINK: I received the project description from faq_handler. I now have complete information to answer the user's question.
+ACT: complete
+REASON: Have sufficient information from knowledge base to provide comprehensive answer
+
+Example 5 - GitHub Specific:
+User: "Can you list the open issues labeled 'good first issue'?"
+THINK: User wants specific GitHub data about issues with a label. This requires github_toolkit.
+ACT: github_toolkit
+REASON: Need to query repository for issues with specific label
+
+Now analyze the current situation and decide your next action:"""
