What replace_in_paragraph does on Hwpx
AI agents use replace_in_paragraph to create or update resources in Hwpx, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Hwpx environment.
Why replace_in_paragraph is rated Medium
This tool creates or modifies document content reversibly by replacing text within paragraphs. It does not delete data irreversibly (Destructive), execute arbitrary code (Execute), or move money (Financial). The modification is scoped to a paragraph and preserves formatting, reducing blast radius compared to broader document replacements.
From the tool's definition Tool description states it performs text substitution ('부분 텍스트를 치환합니다') within a single paragraph while maintaining run formatting ('run 서식을 유지하며'). The sibling tools include add_heading, add_paragraph, add_table — all Write operations.
