Type of Behavior Issue

Claude refused a reasonable request

What You Asked Claude to Do

Reports i runned for weeks are not sent by email anymore.
Security kicks in and says it violates new antropic rules
I pull reports from powerbi, make tailored xls
And html dashboards and send it to company people on same domain to action them.
It says its sensitive and therefore it wont help me to send it out.
Why is that?! Thats new since the 30th of September.
I find no way around it.
How come
You deceide this for me?
Help all my workflows are now broken /
Big hot to my company

What Claude Actually Did

Requesting site scope should grant site scope. The grant should persist across sessions and be visible and revocable in a list of approved sites. If a site cannot be granted persistently by policy, say so explicitly instead of silently downgrading the request to one use.

A scheduled, unattended run should never block on an approval prompt. With no human present there is nobody to answer it, so it should fail immediately with a clear reason and write nothing. It must also not resume hours later into a slot where the next scheduled firing is already running — a firing that has been superseded should be cancelled, not queued. Two runs of the same task should never execute concurrently.

Expected Behavior

  1. Every request for site scope returns "granted for one use". No always/site option is ever offered. The approved-sites list stays empty.
  2. The 30-Sep 18:38 firing blocked ~8 hours on the prompt, resumed at 02:50 while the 01-Oct 02:38 firing was running, both computed the same diff and both wrote the same two events — duplicates in my calendar.
