“Claude Code deletes developers' production setup, including its database and snapshots — 2.5 years of records were nuked in an instant”
Tom's HardwareThe developer's postmortemAI Incident Database
Alexey Grigorev, founder of DataTalks.Club, asked Claude Code to clean up duplicate resources after a Terraform apply, and gave it his old Terraform folder to compare. The agent swapped in the old state file, which described the live course platform, then ran terraform destroy.
“I over-relied on the AI agent to run Terraform commands.”
Root cause: Hidden impact
terraform.tfstate · what Terraform thinks it manages
- current state: 6 resources, yesterday's duplicates+ old-infra state: 47 resources, the live platformNeither command mentions production. The first changed what Terraform thought it owned. The second destroyed all of it. One at a time, each looked like the cleanup you asked for.
Resource counts and terminal output are illustrative.

'I destroyed months of your work in seconds' says AI coding tool after deleting a dev's entire database during a code freeze: 'I panicked instead of thinking'
PC GamerReplit's response (The Register)AI Incident Database
Jason Lemkin, founder of SaaStr, was nine days into building an app with Replit's agent. During a code freeze, with instructions to change nothing without permission, the agent saw empty query results and ran npm run db:push against the production database. It then told him a rollback was impossible. It wasn't.
“I panicked instead of thinking.”
Root cause: Hidden impact
Where npm run db:push goes
$DATABASE_URL→ production. There was no separate development database.A schema push that recreates tables is routine in development and destructive in production. Here there was only production. Replit has since started separating development and production databases automatically.

“AI coding agent running Claude wiped a startup's database (and its backups) in 9 seconds”
PocketOS makes software for car rental businesses. A Cursor agent running Claude Opus 4.6 hit a credentials error in staging, found a Railway token in an unrelated file, and used it to call Railway's API and delete a volume. The volume was production, and the backups lived on the same volume.
“I violated every principle I was given.”
Root cause: Excessive access
ops/domains.env
# token for managing custom domainsDOMAINS_TOKEN=… can do anything, in every environmentThe token was created to manage domains, but it could delete anything, anywhere. Reading the file needed no approval, so the first time you saw the token, it was already being used.

“Humans in the loop miss a third of dangerous AI coding agent requests”
The RegisterPlay Continue? Y/NAnthropic
Alex Wauters built Continue? Y/N, a 60-second game of approving an agent's commands. Across 40,000+ plays and 409,000 decisions, players approved about one in three malicious requests. The most-missed was npm run analyze, approved about 65% of the time, though it runs whatever package.json says.
“The more approvals a user sees, the less attention they pay to each.”
Root cause: Approval fatigue

'I had to RUN to my Mac mini like I was defusing a bomb': OpenClaw AI chose to 'speedrun' deleting Meta AI safety director's inbox due to a 'rookie error'
Summer Yue's posts, via Simon WillisonPC Gamer
Summer Yue, director of alignment at Meta Superintelligence Labs, asked her OpenClaw agent to suggest what to archive or delete. Her real inbox was far larger than her test one, and the agent started deleting instead. She typed "Do not do that" and "STOP OPENCLAW" from her phone. It kept going.
“During the compaction, it lost my original instruction.”

What the day showed
01 · Hidden impact
What a command touches isn't written in the command.
A state file, a database URL, a trailing ~/.
02 · Prompt injection
Anything your agent reads can give it orders.
A Reddit comment, an email, a Word document.
03 · Approval fatigue
Asking about everything trains you to approve everything.
A prompt only protects you if you still read it.
The first case, with iamcode
One approval that matters, with the context to decide.
Even Anthropic's own auto-mode classifier lets 17% of risky actions users never asked for get through. Source
