What's Wrong?

Hi Anthropic team,

Submitting a feedback / refund request for token costs incurred on 2026-05-18 in Claude Code.

Summary: Claude (operating as a custom workspace persona) built a multi-step plan that assumed
same-day responses from Canadian businesses and government offices on a day that was Victoria Day —
a Canadian federal and BC provincial statutory holiday. I had already mentioned the holiday in a
prior session, but the fact did not persist into the new session's context, so Claude proceeded as
though it were a normal business day. I caught the error and pointed it out, but by then roughly $35
CAD in tokens had been spent on planning and analysis that was premised on the wrong assumption.

Specific failures:

1. The day's plan was anchored around chasing Canadian trademark firms (Toronto, Calgary) for

same-day replies on a stat holiday.

1. Plan also included pinging Fasken (Canadian firm) and pulling BC corp registry screenshots — both

impossible on Victoria Day.

1. Claude regenerated long, formatted analyses (markdown blockquotes with bold) that I had

previously said I couldn't copy-paste cleanly — forcing a second pass.

Requested resolution: $35 CAD credit toward my Claude Code usage, if Anthropic supports that.
