Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Adds substantial behavior beyond the annotations: asynchronous background parsing that returns status 'parsing' plus an id, a polling interval, URL eligibility rules (no LinkedIn, private networks, or redirects), a 10 MB cap, profile-field preservation, the rule that pasted text never replaces an uploaded PDF, and a prompt-injection warning. This is unusually rich disclosure for a destructive write tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
