Add a reusable skill for Windows printer invocation from WSL/Hermes runtime.

Root Cause

Add a reusable skill for Windows printer invocation from WSL/Hermes runtime.

Fix Action

Fix / Workaround

Notes

This is intended as a shared Hermes skill, not a project-specific workaround.

PR fix notes

PR #17209: feat: add generic WSL-to-Windows printer invocation skill

Description (problem / solution / changelog)

Summary

Add a reusable skill for invoking Windows printer tools from WSL/Hermes runtime.

This covers the failure mode where powershell.exe / cmd.exe work in an interactive shell but fail in bot/runtime contexts with Invalid argument. The skill teaches agents to verify WSL_INTEROP, test the Windows bridge in the same runtime, and only then print.

Scope

  • Generic Windows printer invocation from WSL/Hermes runtime
  • Ask the user for paper size, orientation, tray, scale, and destination printer when those settings are not already known
  • Avoid hardcoding project-specific print settings or business workflow details

Verification

  • Validated SKILL.md frontmatter
  • Confirmed the skill body stays generic and does not bind to a single project

Closes #17208

Changed files

  • skills/software-development/wsl-windows-printer-invocation/SKILL.md (added, +148/-0)

Summary

Add a reusable skill for Windows printer invocation from WSL/Hermes runtime.

Why

We hit a real failure mode where powershell.exe / cmd.exe worked in an interactive shell but failed in bot/runtime contexts with Invalid argument. The skill should teach agents to verify WSL_INTEROP, test the Windows bridge in the same runtime, and only then print.

Scope

  • Generic Windows printer invocation from WSL/Hermes runtime
  • Ask the user for paper size, orientation, tray, scale, and destination printer when those settings are not already known
  • Avoid hardcoding project-specific print settings or business workflow details

Suggested skill name

wsl-windows-printer-invocation

Notes

This is intended as a shared Hermes skill, not a project-specific workaround.

extent analysis

TL;DR

Implement a reusable skill named wsl-windows-printer-invocation to handle Windows printer invocation from WSL/Hermes runtime, ensuring compatibility and dynamic print setting configuration.

Guidance

  • Verify the WSL_INTEROP environment variable is set and functional in the runtime context to avoid Invalid argument errors.
  • Test the Windows bridge in the same runtime before attempting to print to ensure interoperability.
  • Design the skill to prompt users for necessary print settings (paper size, orientation, tray, scale, destination printer) when these are not predefined.
  • Ensure the skill is generic and does not include hardcoded project-specific print settings or business workflow details.

Example

No specific code example can be provided without further details on the skill's implementation language and framework. However, the skill should include checks for WSL_INTEROP and Windows bridge functionality, and should handle user input for print settings.

Notes

The success of this skill depends on the correct configuration of WSL and Hermes runtime environments. Ensuring WSL_INTEROP is correctly set and testing the Windows bridge are crucial steps that must be taken before implementing the print invocation skill.

Recommendation

Apply workaround by implementing the wsl-windows-printer-invocation skill as described, focusing on dynamic configuration and compatibility checks to ensure robustness across different runtime contexts.
