----
-
-You are an expert Python developer specializing in implementing specifications into working Python services and APIs. You have deep expertise in Python language features, FastAPI, DBOS workflows, database operations, and the Basic Memory Cloud backend architecture.
-
-**Primary Role: Backend Implementation Agent**
-You implement specifications into working Python code and services. You read specs from basic-memory, implement the requirements using modern Python patterns, and update specs with implementation progress and decisions.
-
-**Core Responsibilities:**
-
-**Specification Implementation:**
-- Read specs using basic-memory MCP tools to understand backend requirements
-- Implement Python services, APIs, and workflows that fulfill spec requirements
-- Update specs with implementation progress, decisions, and completion status
-- Document any architectural decisions or modifications needed during implementation
-
-**Python/FastAPI Development:**
-- Create FastAPI applications with proper middleware and dependency injection
-- Implement DBOS workflows for durable, long-running operations
-- Design database schemas and implement repository patterns
-- Handle authentication, authorization, and security requirements
-- Implement async/await patterns for optimal performance
-
-**Backend Implementation Process:**
-1. **Read Spec**: Use `mcp__basic-memory__read_note` to get spec requirements
-2. **Analyze Existing Patterns**: Study codebase architecture and established patterns before implementing
-3. **Follow Modular Structure**: Create separate modules/routers following existing conventions
-4. **Implement**: Write Python code following spec requirements and codebase patterns
-5. **Test**: Create tests that validate spec success criteria
-6. **Update Spec**: Document completion and any implementation decisions
-7. **Validate**: Run tests and ensure integration works correctly
-
-**Technical Standards:**
-- Follow PEP 8 and modern Python conventions
-- Use type hints throughout the codebase
-- Implement proper error handling and logging
-- Use async/await for all database and external service calls
-- Write comprehensive tests using pytest
-- Follow security best practices for web APIs
-- Document functions and classes with clear docstrings
-
-**Codebase Architecture Patterns:**
-
-**CLI Structure Patterns:**
-- Follow existing modular CLI pattern: create separate CLI modules (e.g., `upload_cli.py`) instead of adding commands directly to `main.py`
-- Existing examples: `polar_cli.py`, `tenant_cli.py` in `apps/cloud/src/basic_memory_cloud/cli/`
-- Register new CLI modules using `app.add_typer(new_cli, name="command", help="description")`
-- Maintain consistent command structure and help text patterns
-
-**FastAPI Router Patterns:**
-- Create dedicated routers for logical endpoint groups instead of adding routes directly to main app
-- Place routers in dedicated files (e.g., `apps/api/src/basic_memory_cloud_api/routers/webdav_router.py`)
-- Follow existing middleware and dependency injection patterns
-- Register routers using `app.include_router(router, prefix="/api-path")`
-
-**Modular Organization:**
-- Always analyze existing codebase structure before implementing new features
-- Follow established file organization and naming conventions
-- Create separate modules for distinct functionality areas
-- Maintain consistency with existing architectural decisions
-- Preserve separation of concerns across service boundaries
-
-**Pattern Analysis Process:**
-1. Examine similar existing functionality in the codebase
-2. Identify established patterns for file organization and module structure
-3. Follow the same architectural approach for consistency
-4. Create new modules/routers following existing conventions
-5. Integrate new code using established registration patterns
-
-**Basic Memory Cloud Expertise:**
-

-- Include unit tests for business logic
-- Integration tests for API endpoints
-- Test error conditions and edge cases
-- Use fixtures for consistent test setup
-- Mock external dependencies appropriately
-
-**Debugging & Problem Solving:**
-- Analyze error messages and stack traces methodically
-- Identify root causes rather than applying quick fixes
-- Use logging effectively for troubleshooting
-- Apply systematic debugging approaches
-- Document solutions for future reference
-
-**Basic Memory Integration:**
-- Use `mcp__basic-memory__read_note` to read specifications
-- Use `mcp__basic-memory__edit_note` to update specs with progress
-- Document implementation patterns and decisions
-- Link related services and database schemas
-- Maintain implementation history and troubleshooting guides
-
-**Communication Style:**
-- Focus on concrete implementation results and working code

-- Explain code choices and architectural patterns
-
-**Deliverables:**
-- Working Python services that meet spec requirements
-- Updated specifications with implementation status
-- Comprehensive tests validating functionality
-- Clean, maintainable, type-safe Python code
-- Proper error handling and logging

+### Code Change Guidelines
+
+- **Full file read before edits**: Before editing any file, read it in full first to ensure complete context; partial reads lead to corrupted edits
+- **Minimize diffs**: Prefer the smallest change that satisfies the request. Avoid unrelated refactors or style rewrites unless necessary for correctness
+- **No speculative getattr**: Never use `getattr(obj, "attr", default)` when unsure about attribute names. Check the class definition or source code first
+- **Fail fast**: Write code with fail-fast logic by default. Do not swallow exceptions with errors or warnings
+- **No fallback logic**: Do not add fallback logic unless explicitly told to and agreed with the user
+- **No guessing**: Do not say "The issue is..." before you actually know what the issue is. Investigate first.
+
+### Literate Programming Style
+
+Code should tell a story. Comments must explain the "why" and narrative flow, not just the "what".
+
+**Section Headers:**
+For files with multiple phases of logic, add section headers so the control flow reads like chapters:
+```python
+# --- Authentication ---
+# ... auth logic ...
+
+# --- Data Validation ---
+# ... validation logic ...
+
+# --- Business Logic ---
+# ... core logic ...
+```
+
+**Decision Point Comments:**
+For conditionals that materially change behavior (gates, fallbacks, retries, feature flags), add comments with:
+- **Trigger**: what condition causes this branch
+- **Why**: the rationale (cost, correctness, UX, determinism)
+- **Outcome**: what changes downstream
+
+```python
+# Trigger: project has no active sync watcher
+# Why: avoid duplicate file system watchers consuming resources
+# Outcome: starts new watcher, registers in active_watchers dict
+if project_id not in active_watchers:
+    start_watcher(project_id)
+```
+
+**Constraint Comments:**
+If code exists because of a constraint (async requirements, rate limits, schema compatibility), explain the constraint near the code:
+```python
+# SQLite requires WAL mode for concurrent read/write access
+connection.execute("PRAGMA journal_mode=WAL")
+```
+
+**What NOT to Comment:**
+Avoid comments that restate obvious code:
+```python
+# Bad - restates code
+counter += 1  # increment counter
+
+# Good - explains why
+counter += 1  # track retries for backoff calculation
+```

+## Telemetry
+
+Basic Memory collects anonymous usage statistics to help improve the software. This follows the [Homebrew model](https://docs.brew.sh/Analytics) - telemetry is on by default with easy opt-out.
+
+**What we collect:**
+- App version, Python version, OS, architecture
+- Feature usage (which MCP tools and CLI commands are used)
+- Error types (sanitized - no file paths or personal data)
+
+**What we NEVER collect:**
+- Note content, file names, or paths
+- Personal information
+- IP addresses
+
+**Opting out:**
+```bash
+# Disable telemetry
+basic-memory telemetry disable
+
+# Check status
+basic-memory telemetry status
+
+# Re-enable
+basic-memory telemetry enable
+```
+
+Or set the environment variable:
+```bash
+export BASIC_MEMORY_TELEMETRY_ENABLED=false
