dsh-spawn

Provides a spawn tool that executes a command directly without shell, and optional stat and list_dir tool plugins.

Installation

Install the npm package into a DSH profile after the release is published:

dsh plugin --profile web add @snylonue/dsh-spawn

Tools and preset

spawn requires the jobs, sandbox, and sandboxPolicy services. Every invocation starts a job; foreground calls wait for completion and move the job to the background on timeout. Infrastructure failures throw in foreground calls and settle background jobs as failed; nonzero command exits remain ordinary results.

The @snylonue/dsh-spawn entry registers only spawn. Load @snylonue/dsh-spawn/stat and @snylonue/dsh-spawn/list-dir separately for filesystem queries. The PTC-spawn preset enables all three by default. To disable either query tool in that preset, set disabled: true on its entry under preset-ptc-spawn.config.plugins:

The top-level tool-stat and tool-list-dir entries are separate declarations and disabled by default. Changing them does not disable the copies inside the preset. Edit the corresponding preset child entries shown below:

- id: tool-stat
  name: '@snylonue/dsh-spawn/stat'
  disabled: true
- id: tool-list-dir
  name: '@snylonue/dsh-spawn/list-dir'
  disabled: true

A preset (PTC-spawn (id ptc-spawn)) is provided, which is based on PTC mode and replaces shell with above tools.

Hopefully, this tool improves how a model executes programs (typesrcipt is better than bash to compose multiple programs and process outputs and prevents model struggling with pwsh).
