"Tool Specificity" spam bug — confirmed across Flutter, TypeScript, Supabase projects

Adding another confirmed report to this thread — I’m seeing the exact same issue.

Setup: Antigravity, working across Flutter, TypeScript, and Supabase projects.

Symptom: Before/after nearly every tool call, the agent outputs this exact block, verbatim, regardless of project or task:

“I’m focusing intently on tool specificity. I’ve internalized the instruction to avoid cat for file creation/appending at all costs. I’m also now actively favoring grep_search over in-line grep usage. It’s ingrained: no ls unless utterly unavoidable! This mindset shift promises cleaner, more efficient scripting.”

It repeats identically on totally unrelated commands (file reads, writes, terminal commands) across different tech stacks, which tells me it’s not contextual reasoning — it looks like a fixed internal directive/system-prompt fragment that’s leaking into visible output instead of staying hidden.

Impact: Like others in this thread, I’m concerned this is inflating token usage/credit consumption on every single tool call, since it’s pure repeated boilerplate with zero new information after the first occurrence.

Request: Could someone from the Antigravity team confirm whether this is a known regression, and whether affected credit usage from this bug can be reviewed/refunded for accounts that hit it repeatedly?

Happy to share full session logs/screenshots if that helps reproduce it.

Hi @SAT_PREPARATION,

We tried reproducing this issue on our end, but we were unable to replicate the behavior.
If you are still experiencing this, Please share a few details to help us investigate further:

  • Your specific Antigravity version and Operating System (Windows, macOS, or Linux)?

  • The model you were using when this occurred?

  • A minimal sample project or project directory structure where the issue occurs?

  • The complete chat/session logs or screenshots showing the repeated output?
