jharness-tools

Ready-to-use filesystem, shell, interaction, and child-agent tools implementing the JHarness kernel tool contracts.

uv add jharness-tools

from jharness.tools import GlobTool, GrepTool, ReadTool

Filesystem tools are rooted in one workspace and reject path escapes. BashTool uses a bounded non-interactive Bash process and a minimal environment by default, but it is not an operating-system sandbox: commands retain the filesystem and network access granted by the host. inherit_environment=True explicitly exposes the full host environment.

Workspace path checks are not a mount namespace; mutually untrusted writers need dedicated filesystem isolation and hard-link controls. Process-tree cleanup is best effort, so containers—especially PID 1—must forward signals and reap child processes.

Interaction tools suspend for a host response. Child-agent tools require a host-owned AgentBackend; the host remains responsible for authorization, idempotency, supervision, and telemetry.
