Mike Swanson 6122efe98c skills: harvest 4 MIT dev skills from obra/superpowers (awesome-claude-skills)
From the ComposioHQ/awesome-claude-skills list. Checked licenses BEFORE copying:
- threat-hunting-with-sigma-rules: repo is gone (GitHub 404) -- not harvested.
- forensics (mhattingpete): repo restructured, those skills no longer exist -- not harvested.
- pdf / mcp-builder (Anthropic official): LICENSE.txt FORBIDS copying out of the
  Service / derivatives / redistribution -- NOT harvestable into this repo (install via
  the official Claude Code marketplace instead if wanted).
- obra/superpowers: MIT -> the only legally harvestable set; imported with attribution.

Imported (each with its own MIT LICENSE copy + SOURCE.md provenance, commit a21956e48c13,
ASCII-normalized to house style, no emojis):
- using-git-worktrees
- test-driven-development (+ testing-anti-patterns.md)
- root-cause-tracing (+ find-polluter.sh helper, emojis -> ASCII markers)
- brainstorming (methodology only; upstream visual websocket server intentionally omitted)

Faithful imports -- content not reworded beyond ASCII typography/emoji normalization.
