Add tool strategy documentation with triggering mechanisms and text processing references

- Introduced auto and manual triggering mechanisms for Exa.
- Added quick reference guides for sed and awk text processing.
- Established a fallback strategy for handling edit failures.

+# Tool Strategy
+
+## ⚡ Exa Triggering Mechanisms
+
+**Auto-Trigger**:
+- User mentions "exa-code" or code-related queries → `mcp__exa__get_code_context_exa`
+- Need current web information → `mcp__exa__web_search_exa`
+
+**Manual Trigger**:
+- Complex API research → Exa Code Context
+- Real-time information needs → Exa Web Search
+
+## ⚡ Bash Text Processing (sed/awk)
+
+**When to Use**: Edit tool fails 2+ times on same file
+
+### sed Quick Reference
+
+```bash
+# Replace first occurrence per line
+sed 's/old/new/' file.txt
+
+# Replace all occurrences (global)
+sed 's/old/new/g' file.txt
+
+# In-place edit (modify file directly)
+sed -i 's/old/new/g' file.txt
+
+# Delete lines matching pattern
+sed '/pattern/d' file.txt
+
+# Insert line before match
+sed '/pattern/i\new line' file.txt
+
+# Insert line after match
+sed '/pattern/a\new line' file.txt
+
+# Replace on specific line number
+sed '5s/old/new/' file.txt
+
+# Multi-line replacement (escape newlines)
+sed ':a;N;$!ba;s/old\npattern/new\ntext/g' file.txt
+```
+
+### awk Quick Reference
+
+```bash
+# Print specific column
+awk '{print $1}' file.txt
+
+# Print lines matching pattern
+awk '/pattern/' file.txt
+
+# Replace field value
+awk '{$2="new"; print}' file.txt
+
+# Conditional replacement
+awk '/pattern/{gsub(/old/,"new")}1' file.txt
+
+# Insert line after match
+awk '/pattern/{print; print "new line"; next}1' file.txt
+
+# Multi-field operations
+awk -F',' '{print $1, $3}' file.csv
+```
+
+### Fallback Strategy
+
+1. **Edit fails 2+ times** → Try sed for simple replacements
+2. **sed fails** → Try awk for complex patterns
+3. **awk fails** → Use Write to recreate file
