Struct FilesystemConfig 

#[non_exhaustive]
pub struct FilesystemConfig {
    pub allow_write: Vec<String>,
    pub deny_write: Vec<String>,
    pub deny_read: Vec<String>,
    pub inherit_readable: bool,
}

Filesystem access rules.

Designed for coding agent scenarios: the full host filesystem remains readable by default (binaries, dotfiles, shared libraries), while writes are restricted to the working directory. Enforcement mechanism varies by IsolationLevel:

• None / CgroupTracking: AppArmor (Linux) or Seatbelt (macOS) profile
• Namespace: bind-mount policy derived from these rules
• Container: translated to podman --volume flags

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

allow_write: Vec<String>

Paths where writes are explicitly permitted.

Supports absolute paths and cwd-relative paths (including glob patterns such as "./src/**"). Default: ["."] — working directory only.

deny_write: Vec<String>

Paths where writes are blocked, evaluated after allow_write.

Example: ["./secrets/", ".env"]

deny_read: Vec<String>

Paths where reads are blocked.

Example: ["/etc/shadow", "~/.ssh/id_rsa"]

inherit_readable: bool

Expose the entire host filesystem as readable.

true by default — preserves access to binaries, dotfiles, and shared libraries. In Namespace mode this causes the host root to be bind-mounted read-only; deny_read entries are excluded. Set to false for a stripped environment.
