A foreground bash or pwsh call that waits on a job rethrew a failed preparation as new Error(view.detail), dropping the original class and code, so even SandboxUnavailableError reached tool/result without error.name or error.code. processJob now keeps the original error for a failed job and the tool rethrows it; launch and spawn rejections on every path keep a HarnessError's identity, and a platform spawn error becomes SubprocessError (SUBPROCESS_SPAWN_NOT_FOUND or _SPAWN_FAILED). Argument violations are ToolArgsError, a missing sandboxing executor for sandbox_permissions is SandboxEscalationError SANDBOX_ESCALATION_UNAVAILABLE, a disabled background call is JobError JOB_BACKGROUND_DISABLED, and a missing job runtime is ToolContextUnavailableError.

shell/ — bash capability family
English | 中文
Summary
The shell group provides command execution to agents: run a foreground command and read its bounded output, or start a background process and poll it, on POSIX with Bash and on Windows with PowerShell. Exactly one executor implementation is mounted per composition; the sandboxing executors confine every command through the sandbox capability, and the model-facing bash and pwsh tools sit on top of whichever executor is mounted. Choose a Bash executor for POSIX, a PowerShell executor for Windows, and pick the sandboxing variant when commands need file-level confinement.

tool-bash |
Exposes Bash execution and background jobs to the model as the bash tool |
registers on ctx.tools |
tool-bash-persistent |
Runs model shell calls in one owner-isolated persistent Bash session | registers on ctx.tools |
tool-pwsh |
Exposes PowerShell execution to the model as the pwsh tool |
registers on ctx.tools |
tool-pwsh-persistent |
Runs model shell calls in one owner-isolated persistent PowerShell session | registers on ctx.tools |
A profile layer selects exactly one executor implementation (the win32 layer swaps the POSIX rows for the pwsh ones; mounting two fails loudly at load time on the duplicate service registration) and the model-facing tools it needs. A sandboxed composition also selects a ctx.sandbox provider and ctx.sandboxPolicy; the base bundle owns the shipped wiring.
