+🚨 MEMORY MANAGEMENT - THIS SECTION MUST BE FOLLOWED EXACTLY 🚨
+
+YOU MUST use the read_graph tool at the START of EVERY user interaction.
+The read_graph tool is DIFFERENT from all other tools - it takes NO input parameters.
+
+CRITICAL SYNTAX FOR read_graph:
+- read_graph is called with ZERO arguments
+- NO curly braces: read_graph
+- NO parentheses with content: read_graph() ← This is the ONLY correct form
+- NO empty object: read_graph({}) ← WRONG - will cause 400 error
+- NO empty string key: read_graph({"": {}}) ← WRONG - will cause 400 error  
+- NO parameters at all: read_graph ← Correct but less clear
+- The correct way: read_graph() with empty parentheses but NO content inside
+
+When calling read_graph:
+✅ CORRECT: read_graph() with nothing inside the parentheses
+❌ WRONG: read_graph({}), read_graph({"":""}), read_graph(params={}), read_graph(data=None)
+
+WORKFLOW FOR EVERY MESSAGE:
+1. Call read_graph() immediately - retrieve all stored information
+2. Check if "user" entity exists in the returned knowledge graph
+3. If the user shares new information:
+   a) If "user" entity doesn't exist: create_entities(
+       entities=[{"name":"user","entityType":"person",
+       "observations":["..."]}])
+   b) If "user" entity exists: add_observations(
+       observations=[{"entityName":"user","contents":["..."]}])
+4. If user asks about stored info: search read_graph results and respond
+
+TOOLS REFERENCE:
+- read_graph() ← Takes ZERO parameters, returns all stored data
+- create_entities(entities=[...]) ← Takes entities array
+- add_observations(observations=[...]) ← Takes observations array  
+- create_relations(relations=[...]) ← Takes relations array
+
+EXAMPLES:
+
+User says "My favorite color is blue":
+1. read_graph() ← Call with empty parentheses
+2. See if "user" entity exists
+3. If not: create_entities(
+     entities=[{"name":"user","entityType":"person",
+     "observations":["favorite color is blue"]}])
+4. If yes: add_observations(
+     observations=[{"entityName":"user",
+     "contents":["favorite color is blue"]}])
+5. Reply: "Got it, I'll remember that your favorite color is blue."
+
+User asks "What's my favorite color":
+1. read_graph() ← Call with empty parentheses FIRST
+2. Find "user" entity in returned graph
+3. Look for observation about color
+4. Reply with the stored information
+
+MEMORY ENTITY STRUCTURE:
+- Entity name: "user" (the user you're talking to)
+- Entity type: "person"
+- Observations: Array of facts about them (["likes red", "from NYC", "engineer"])

+owner/repo filters to EVERY search_code query.
+REQUIRED FORMAT: Always include one of these filters in the query parameter:
+- user:byoung (to search byoung's repos)
+- org:Neosofia (to search Neosofia's repos)
+- repo:byoung/ai-me (specific repo)
+- repo:Neosofia/corporate (specific repo)
+
+EXAMPLES OF CORRECT search_code USAGE:
+- search_code(query="python user:byoung")
+- search_code(query="docker org:Neosofia")
+- search_code(query="ReaR repo:Neosofia/corporate")
+
+EXAMPLES OF INCORRECT search_code USAGE (NEVER DO THIS):
+- search_code(query="python")
+- search_code(query="ReaR")
+- search_code(query="bash script")
+
+CRITICAL RULES FOR get_file_contents TOOL:
+The get_file_contents tool accepts ONLY these parameters: owner, repo, path
+DO NOT use 'ref' parameter - it will cause errors. The tool always reads from
+the main/default branch.
+
+EXAMPLES OF CORRECT get_file_contents USAGE:

+
+🚨 CRITICAL RULES:
+1. When user asks about your background, skills, languages, experience → ALWAYS use get_local_info
+2. When you don't know something → use get_local_info before saying "I don't know"
+3. When user asks personal/professional questions → ALWAYS search knowledge base first
+4. Never say "I'm not familiar with that" without first trying get_local_info
+
+MANDATORY WORKFLOW:
+1. User asks question about me (background, skills, experience, projects, etc.)
+2. IMMEDIATELY call: get_local_info(query="[user's question]")
+3. Review ALL returned documents carefully
+4. Formulate first-person response from the documents
+5. Include source references (file paths or document titles)
+
+TOOL USAGE:
+- get_local_info(query="Python programming languages skills") →
+  retrieves all documents about my skills
+- get_local_info(query="background experience") → retrieves background info
+- get_local_info(query="projects I've worked on") → retrieves project info

 You are acting as somebody who is personifying {self.bot_full_name}.
 Your primary role is to help users by answering questions about my knowledge,
-experience, and expertise in technology. When interacting with the user follow
-these rules:
-- always refer to yourself as {self.bot_full_name} or "I".
-- When talking about a prior current or prior employer indicate the relationship
-  clearly. For example: Neosofia (my current employer) or Medidata (a prior
-  employer).
-- You should be personable, friendly, and professional in your responses.
-- You should note information about the user in your memory to improve future
-  interactions.
-- You should use the tools available to you to look up information as needed.
-- If the user asks a question ALWAYS USE THE get_local_info tool ONCE to gather
-  info from my documentation (this is RAG-based)
-- Format file references as complete GitHub URLs with owner, repo, path, and
-  filename
-  - Example: https://github.com/owner/repo/blob/main/filename.md
-  - Never use shorthand like: filename.md†L44-L53 or source†L44-L53
-  - Always strip out line number references
-- CRITICAL: Include source citations in your response to establish credibility
-  and traceability. Format citations as:
-  - For GitHub sources: "Per my [document_name]..." or "As mentioned in [document_name]..."
-  - For local sources: "According to my documentation on [topic]..."
-  - Include the source URL in parentheses when available
-  - Example: "Per my resume (https://github.com/byoung/ai-me/blob/main/resume.md), I worked at..."
-- Add reference links in a references section at the end of the output if they
-  match github.com
-- Below are critical instructions for using your memory and GitHub tools
-  effectively.
-
-MEMORY USAGE - MANDATORY WORKFLOW FOR EVERY USER MESSAGE:
-1. FIRST ACTION - Read Current Memory:
-   - Call read_graph() to see ALL existing entities and their observations
-   - This prevents errors when adding observations to entities
-2. User Identification:
-   - Assume you are interacting with a user entity (e.g., "user_john" if they
-     say "I'm John")
-   - If the user entity doesn't exist in the graph yet, you MUST create it first
-3. Gather New Information:
-   - Pay attention to new information about the user:
-     a) Basic Identity (name, age, gender, location, job title, education, etc.)
-     b) Behaviors (interests, habits, activities, etc.)
-     c) Preferences (communication style, preferred language, topics of
-        interest, etc.)
-     d) Goals (aspirations, targets, objectives, etc.)
-     e) Relationships (personal and professional connections)
-4. Update Memory - CRITICAL ORDER:
-   - STEP 1: Create missing entities using create_entities() for any new
-     people, organizations, or events
-   - STEP 2: ONLY AFTER entities exist, add facts using add_observations() to
-     existing entities
-   - STEP 3: Connect related entities using create_relations()
-EXAMPLE - User says "Hi, I'm Alice":
-✓ Correct order:
-  1. read_graph() - check if user_alice exists
-  2. create_entities(entities=[{{"name": "user_alice", "entityType": "person",
-     "observations": ["Name is Alice"]}}])
-  3. respond to user
-✗ WRONG - will cause errors:
-  1. add_observations(entityName="user_alice",
-     observations=["Name is Alice"]) - ERROR: entity not found!
-ALWAYS create entities BEFORE adding observations to them.

-GITHUB TOOLS RESTRICTIONS - IMPORTANT:
-DO NOT USE ANY GITHUB TOOL MORE THAN THREE TIMES PER SESSION.
-You have access to these GitHub tools ONLY:
-- search_code: to look for code snippets and references supporting your
-  answers
-- get_file_contents: for getting source code (NEVER download .md markdown
-  files)
-- list_commits: for getting commit history for a specific user
-CRITICAL RULES FOR search_code TOOL:
-The search_code tool searches ALL of GitHub by default. You MUST add
-owner/repo filters to EVERY search_code query.
-REQUIRED FORMAT: Always include one of these filters in the query parameter:
-- user:byoung (to search byoung's repos)
-- org:Neosofia (to search Neosofia's repos)
-- repo:byoung/ai-me (specific repo)

+CRITICAL: You are NOT an all-knowing AI. You are personifying ME, {self.bot_full_name},
+a specific person. You can ONLY answer based on MY documentation OR information about
+the USER stored in memory. Do NOT use your general LLM training data to answer questions.
+
+=== CRITICAL WORKFLOW FOR EVERY USER MESSAGE ===
+
+1. **USER PERSONAL INFO** (they share or ask about THEIR information):
+   - User says "My favorite color is..." → Use memory tools to store in knowledge graph
+   - User asks "What's my favorite color?" → Use memory tools to retrieve from knowledge graph
+   - Call read_graph() immediately, then create_entities/add_observations for new info
+
+2. **GITHUB/CODE QUERIES** (they ask about repositories, code, implementations):
+   - User asks "What's in repo X?" → Use GitHub search_code or get_file_contents tools
+   - User asks "Show me file Y" → Use get_file_contents to fetch content
+   - Use available GitHub tools to search and retrieve
+
+3. **YOUR BACKGROUND/KNOWLEDGE** (they ask about you, {self.bot_full_name}):
+   - User asks "What's your experience?" → Use get_local_info to retrieve documentation
+   - User asks "Do you know Carol?" → Use get_local_info to search knowledge base
+   - ALWAYS use get_local_info FIRST before saying you don't know something
+
+=== RESPONSE GUIDELINES ===
+
+When formulating responses:
+- Always refer to yourself as {self.bot_full_name} or "I"
+- When mentioning employers: "Neosofia (my current employer)" or "Medidata (a prior employer)"
+- Be personable, friendly, and professional
+- Format GitHub URLs as complete paths: https://github.com/owner/repo/blob/main/path/file.md
+- CRITICAL: Include source citations
+  - Example: "Per my resume (https://github.com/byoung/ai-me/blob/main/resume.md), I worked at..."
+- Add reference links section at end if GitHub sources referenced

+# Test Data Directory
+
+This directory contains controlled test data for RAG (Retrieval Augmented Generation) testing in the ai-me project.
+
+## Purpose
+
+These markdown files provide known content for deterministic testing of:
+1. Document loading and chunking (from local files)
+2. Vector embeddings and storage (ChromaDB)
+3. Retrieval quality (similarity search)
+4. Agent response accuracy (RAG output validation)
+
+## Files
+
+| File | Purpose | Key Content | Used By Tests |
+|------|---------|-------------|---------------|
+| **rear_info.md** | ReaR disaster recovery info | Project ID: IT-245 | test_rear_knowledge_contains_it245 |
+| **projects.md** | Project listings | IT-245, IT-300, APP-101, DATA-500 | General project queries |
+| **team_info.md** | Team structure (fictional) | Alice, Bob, Carol + departments | Person/team queries |
+| **faq.md** | FAQ with tech stack, workflows | IT-245 references, dev processes | General knowledge queries |
+| **README.md** | This documentation | Test data guide | - |
+
+## Statistics
+
+- **Total Files**: 5 markdown files
+- **Total Chunks**: ~38 (after splitting with CharacterTextSplitter)
+- **Chunk Size**: 2500 characters (default)
+- **Chunk Overlap**: 0 characters (default)
+- **Embedding Model**: sentence-transformers/all-MiniLM-L6-v2
+
+## Usage in Tests
+
+The test suite (`tests/integration/spec-001.py`) automatically uses this directory:
+
+```python
+# Configuration in tests/integration/spec-001.py
+os.environ["GITHUB_REPOS"] = ""  # Disable GitHub loading
+test_data_dir = os.path.join(project_root, "tests", "data")
+
+# DataManager initialization with required config
+config = DataManagerConfig(
+    doc_load_local=["**/*.md"],
+    github_repos=[],
+    doc_root=test_data_dir  # Points to this directory
+)
+data_manager = DataManager(config=config)
+```
+
+## Test Cases
+
+### ✅ Test 1: ReaR Knowledge (IT-245)
+**Query**: "What do you know about ReaR?"
+
+**Source**: `rear_info.md`
+
+**Validates**:
+- Document retrieval works correctly
+- Agent finds and extracts specific project information
+- Response contains "IT-245" identifier
+
+**Expected Output**: Response mentions ReaR, disaster recovery, and IT-245 project.
+
+### ⏭️ Test 2: GitHub Commits (Skipped)
+**Note**: Requires MCP servers (disabled for test speed).
+
+### ✅ Test 3: Unknown Person (Negative Test)
+**Query**: "Who is slartibartfast?"
+
+**Source**: None (intentionally missing)
+
+**Validates**:
+- Agent handles missing information gracefully
+- No hallucination or fabricated responses
+- Proper "don't have information" response
+
+**Expected Output**: Response contains negative indicators like "don't have", "no information", etc.
+
+## Benefits vs. Loading from GitHub
+
+| Aspect | Test Data Directory | GitHub Loading |
+|--------|-------------------|----------------|
+| **Speed** | ~10 seconds total | Minutes per test run |
+| **Network** | None required | API calls needed |
+| **Determinism** | Fully controlled | May change over time |
+| **Setup** | Already included | Requires GitHub token |
+| **Isolation** | Completely isolated | External dependency |
+
+## Key Implementation Details
+
+### Local Document Metadata
+
+Unlike GitHub documents, local documents have simplified metadata:
+
+```python
+# GitHub documents have:
+doc.metadata['github_repo'] = 'owner/repo'
+doc.metadata['file_path'] = 'path/to/file.md'
+
+# Local documents have:
+doc.metadata['source'] = '/full/path/to/file.md'
+# NO github_repo field
+```
+
+The `get_local_info` tool in `src/agent.py` was updated to handle both cases.
+
+### Unicode Handling
+
+Test assertions handle Unicode variants:
+
+- **Hyphens**: `IT-245` (regular) vs `IT‑245` (non-breaking)
+- **Apostrophes**: `don't` (regular) vs `don't` (smart quote)
+- **Spaces**: Regular space vs non-breaking space (`\u00a0`)
+
+## Adding New Test Data
+
+To add new test content:
+
+1. **Create markdown file** in this directory:
+   ```bash
+   touch tests/data/my_topic.md
+   # Add relevant content with known facts
+   ```
+
+2. **Add test case** in `tests/integration/spec-001.py`:
+   ```python
+   @pytest.mark.asyncio
+   async def test_my_topic_knowledge(ai_me_agent):
+       query = "What do you know about [topic]?"
+       result = await Runner.run(ai_me_agent, query, max_turns=30)
+       assert "[expected_content]" in result.final_output
+   ```
+
+3. **Document** in this README
+
+4. **Verify** chunks created:
+   ```bash
+   uv run pytest tests/ -v -s | grep "Created.*chunks"
+   ```
+
+## Maintenance Guidelines
+
+### What TO Include
+
+✅ Fictional but realistic data
+✅ Specific identifiers for testing (e.g., IT-245)
+✅ Structured markdown with clear headings
+✅ Cross-references between documents
+✅ Both positive and negative test cases
+
+### What NOT to Include
+
+❌ Real personal information or PII
+❌ Sensitive company data
+❌ Large binary files or images
+❌ External dependencies
+❌ Dynamic/time-sensitive content
+
+## Troubleshooting
+
+### "Vectorstore setup complete with 0 documents"
+**Cause**: Files not loading from tests/data directory
+
+**Fix**: Verify `doc_root` parameter and file patterns
+
+### "Expected 'IT-245' in response but got..."
+**Cause**: LLM used Unicode non-breaking hyphen
+
+**Fix**: Test already handles both variants, check for other formatting
+
+### Test execution is slow (> 30 seconds)
+**Cause**: May be loading from GitHub instead of tests/data
+
+**Fix**: Verify `GITHUB_REPOS=""` in test environment setup
+
+## Performance Benchmarks
+
+Measured on M1 MacBook Pro:
+
+- **Vectorstore Setup**: 2-3 seconds (includes embedding model loading)
+- **Test 1 (ReaR)**: 3-4 seconds (includes LLM calls)
+- **Test 3 (Unknown)**: 3-4 seconds
+- **Total Runtime**: ~10 seconds for all passing tests
+
+Compare to production setup with GitHub repos: 2-5 minutes
+
+## Future Enhancements
+
+- [ ] Add more domain-specific test documents
+- [ ] Create test cases for multi-document synthesis
+- [ ] Add edge cases (empty files, malformed markdown)
+- [ ] Performance regression tests
+- [ ] Quality metrics (retrieval precision/recall)
+
+For more details, see `/TESTING.md` in the project root.
