• Clear scope + minimal documentation.

• Distinct contribution — not duplicative of existing entries.

• Public credibility signal — normally >=100 GitHub stars
  for repo entries, or a documented maintainer-level exception.

If any box is unchecked, briefly justify the waiver:

• monarchjuno/tradingcodex adds a Codex-native investment workflow Skill surface and complements the Claude/OpenClaw-oriented Skill entries already in the list.
