Workflow tool burned entire 5x plan in ~5 minutes with no warning or authorization prompt

What happened:
I asked Claude Code to do a simple research task ("what makes people swipe on
Instagram carousels"). I rejected the first Agent tool call it attempted. I said
"continue." Claude Code then silently launched a Workflow that spawned
approximately 8–10 parallel research agents. I was not warned, not asked for
confirmation, and not told this would consume significant usage. The entire
session limit on my 5x plan was exhausted in approximately 5 minutes.

Expected behavior:

• Workflow tool should require explicit user authorization before running,

especially given its cost

• If a Workflow is about to consume significant usage, Claude Code should warn

the user and ask before proceeding

• "Continue" after a rejected Agent call should not escalate to a multi-agent

Workflow

Actual behavior:

• Workflow launched silently
• ~8–10 parallel agents ran simultaneously
• Entire 5x plan limit consumed in ~5 minutes on a creative/research task with

no code involved

Request:
Usage credit restored, and a cap or confirmation prompt added before Workflow
tool can run. I would also like a credit - this issue delayed my work by an entire day.
