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

⚡ CCW edit_file Tool (AI-Powered Editing)

When to Use: Edit tool fails 1+ times on same file

update Mode (Default)

Best for: Code block replacements, function rewrites, multi-line changes

ccw tool exec edit_file '{
  "path": "file.py",
  "oldText": "def old():\n    pass",
  "newText": "def new():\n    return True"
}'

line Mode (Precise Line Operations)

Best for: Config files, line insertions/deletions, precise line number control

# Insert after specific line
ccw tool exec edit_file '{
  "path": "config.txt",
  "mode": "line",
  "operation": "insert_after",
  "line": 10,
  "text": "new config line"
}'

# Delete line range
ccw tool exec edit_file '{
  "path": "log.txt",
  "mode": "line",
  "operation": "delete",
  "line": 5,
  "end_line": 8
}'

# Replace specific line
ccw tool exec edit_file '{
  "path": "script.sh",
  "mode": "line",
  "operation": "replace",
  "line": 3,
  "text": "#!/bin/bash"
}'

Operations:

insert_before: Insert text before specified line
insert_after: Insert text after specified line
replace: Replace line or line range
delete: Delete line or line range

Mode Selection Guide

Scenario	Mode	Reason
Code refactoring	update	Content-driven replacement
Function rewrite	update	Simple oldText/newText
Config line change	line	Precise line number control
Insert at specific position	line	Exact line number needed
Delete line range	line	Line-based operation

Fallback Strategy

Edit fails 1+ times → Use ccw tool exec edit_file (update mode)
update mode fails → Try line mode with precise line numbers
All fails → Use Write to recreate file

Default mode: update (exact matching with line ending adaptation)
