Use Enhanced Ed Editor for File Modifications

Trust your ed skills, use the eed tool instead of Edit, MultiEdit, or Write tools for file modifications.

Instructions:

Use eed via Bash tool with quoted heredoc pattern:

eed -m "fix something" /unix/style/path/to/file - <<'EOF'
# ed commands here
w
q
EOF

In a git repository - Auto-commit workflow

eed -m "Fix validation logic" file.js - <<'EOF'
2c
validated input
.
w
q
EOF

# Revert the changes when needed
eed --undo

In a non-git repository- Manual commit workflow (for review before commit):

eed file.txt - <<'EOF'
5d
w
q
EOF

# Then apply manually
mv file.txt.eed.preview file.txt

Heredoc usage

• Always use single quote hereod, and avoid using nested heredoc. Do complex editing with multiple sequential eed edits

Important:

• Mandatory tool: Use eed for ALL file modifications
• Avoid nested heredocs: Nested heredocs are fragile and prone to parsing errors.
