Filesystem
The hierarchical collection of files and directories an agent can access through its environment.
Illustrative conversation
- Why did the agent search the repository before editing the configuration?
- Filesystem access exposes paths, but the model still has to load the relevant files into context.
Definition
A filesystem organizes persistent data into paths, files, and directories. An agent reaches it through tools whose working directory, mounted paths, and read or write permissions are defined by the harness or sandbox. A file being accessible does not mean its contents are already in model context; the agent must read the relevant portion, and changes should be verified with diffs or tests.
