tailor_resume · Crosswalk MCP: Risk & Policy

WHAT IT DOES

What tailor_resume does on Crosswalk

AI agents use tailor_resume to create or update resources in Crosswalk — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Crosswalk environment.

WHY IT NEEDS A POLICY

Why tailor_resume needs a policy

This tool modifies existing resume data by customizing it for a job application. This is a reversible Write action (the original resume is stored separately, and tailoring produces a derived variant rather than overwriting the source).

From the tool's definition Tool description states it modifies user's resume: 'Tailor your stored resume for a specific job.' The action of tailoring creates a modified version of stored resume data.
