+## Memory Patterns
+
+- `memory://specs/search` - Exact note
+- `memory://specs/*` - All in folder
+- `memory://*` - Everything
+
+## Traversal Examples
+```python
+# Continue discussion
+context = build_context("memory://discussions/api-design")
+
+# Deep exploration (2 hops)
+context = build_context(
+    "memory://architecture/microservices",
+    depth=2,
+    timeframe="30d"
+)
 
-    Memory URL Format:
-    - Use paths like "folder/note" or "memory://folder/note"
-    - Pattern matching: "folder/*" matches all notes in folder
-    - Valid characters: letters, numbers, hyphens, underscores, forward slashes
-    - Avoid: double slashes (//), angle brackets (<>), quotes, pipes (|)
-    - Examples: "specs/search", "projects/basic-memory", "notes/*"
+# Filtered traversal
+context = build_context(
+    "memory://specs/*",
+    types=["entity", "observation"]
+)
+```
 
-    Timeframes support natural language like:
-    - "2 days ago", "last week", "today", "3 months ago"
-    - Or standard formats like "7d", "24h"
-    """,
+Performance: Depth 1: 100ms, Depth 2: 500ms, Depth 3+: May be slow""",

+

+```markdown
+- [decision] Use REST over GraphQL #api (Better caching)
+- [requirement] Response time < 100ms #performance
+- [task] Implement error handling #todo
+```
+
+**Relations**: `- relation_type [[Target]] (reason)`
+```markdown
+- implements [[API Spec v2]]
+- depends_on [[Auth Service]] (For token validation)
+```
+
+**Inline**: `Text with [[Entity]] reference` creates automatic `relates_to`
+
+## Example Usage
+```python
+write_note(
+    title="API Design",
+    folder="specs",
+    content='''# API Design
+- [decision] REST architecture #api
+- implements [[API Spec v2]]
+See [[Guidelines]] for standards.''',
