-You have Read and Edit tools. Edit the plan file directly — do NOT output the plan content to stdout.
+You have Read, Edit, and the Morph edit_file MCP tool. Prefer the Morph edit_file tool (mcp__morph-fast-tools__edit_file) for edits — it's faster and handles large changes better than legacy Edit. Edit the plan file directly — do NOT output the plan content to stdout.
 - Preserve the YAML frontmatter block (between the --- delimiters) at the top unchanged.
 - Only modify the content below the frontmatter.
 - Print a brief summary to stdout as you work: which changes you're accepting, rejecting, or modifying, and why. Keep it concise — bullet points, not essays."
