We open-sourced bash-tool, the Bash execution engine used by our text-to-SQL agent that we recently re-architected to reduce our token usage, improve the accuracy of the agent's responses, and improve the agent's overall performance.
bash-tool gives your agent a way to find the right context by running bash-like commands over files, then returning only the results of those tool calls to the model.
Context windows can fill up quickly if you include large amounts of text into a prompt. As agents tend to do well with Unix-style workflows like find, grep, jq, and pipes, with bash-tool you can now keep large context local, in a filesystem, and let the agent use those commands to retrieve smaller slices of context on demand.
bash-tool provides bash, readFile, and writeFile tools for AI SDK agents, working with both in-memory and sandboxed environments, and:
runs on top of
just-bash, which interprets bash scripts directly in TypeScript without a shell process or arbitrary binary executionyou can preload that filesystem with your files at startup, so your agent can search them when needed without pasting everything into the prompt
it supports running in-memory or in a custom isolated VM
If you need a real shell, a real filesystem, or custom binaries, you can run the same tool against a Sandbox-compatible API for full VM isolation.
