+# Cognitive Memory SKILL.md: Proactive Edge Creation Updates
+
+## Changes Made
+
+Updated `~/.claude/skills/cognitive-memory/SKILL.md` with three targeted changes to promote edge usage:
+
+1. **New workflow pattern #8** — "Create Edges Between Related Memories" covering all 7 relation types (SOLVES, CAUSES, BUILDS_ON, ALTERNATIVE_TO, REQUIRES, FOLLOWS, RELATED_TO), CLI and MCP examples, graph traversal patterns, and a "when to create edges" guide.
+
+2. **Updated workflow pattern #1** — "Store a Bug Fix" now shows how to relate the solution memory to its problem memory using a SOLVES edge immediately after storing.
+
+3. **Added proactive trigger #11** — Create edges after storing memories, with rationale about enriching RAG retrieval context.
+
+## Motivation
+
+Upcoming RAG server implementation needs rich graph context to surface relevant memories during retrieval. Edges provide relationship signal that pure vector similarity misses.
