# Skill provenance

The skills in this directory are maintained as part of xopc.

## 2026-07 built-in capability packs

- `engineering/define-task` was designed after reviewing
  Apache-2.0-licensed reference material supplied during product planning. Its instructions and
  assets in this repository were written independently for xopc; no reference files or branding
  are redistributed here.
- `documents/pdf`, `documents/docx`, `documents/pptx`, and
  `documents/doc-coauthoring` are clean-room xopc instructions. They do not contain text,
  scripts, templates, or assets from the restricted reference materials reviewed during planning.

## 2026-09 recurring work design

- `engineering/design-recurring-work` was informed by Matt Pocock's public `loop-me` skill.
  Its instructions were written for xopc's Note, Task, Scene, Workflow, and Automation model;
  no third-party skill files are redistributed here.

Before replacing an xopc skill with externally sourced material, confirm that its license permits
copying, modification, and redistribution in the xopc npm package.
