The Bash tool system prompt has been completely rewritten from a monolithic template literal into a modular, array-based builder. While the overall guidance is similar, it now includes:
- A dedicated "# Instructions" section with clearer organization
- Explicit "For git commands:" subsection with safer defaults guidance
- A new "Avoid unnecessary
sleepcommands:" subsection with six specific anti-sleep rules, including: don't poll background tasks, userun_in_backgroundfor long-running commands, don't retry in sleep loops, and keep sleep durations to 1-5 seconds - Sandbox description restructured into a more readable format
Evidence
New modular Bash description builder function (search for "Avoid unnecessary" and "Do not sleep between commands")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
