When I originally contributed markdown.instructions.md, it really should have been named markdown-content-creation.md as it had instructions that were content creation specific.
I propose that:
- Rename /instructions/markdown.instructions.md and update to leverage better validation checklist.
- Submit new /instructions/markdown.instructions.md with generic instructions/validation checklist for applying CommonMark spec (https://un5m3xt22y4a5ydj3javerhh.julianrbryant.com/0.31.2/).
- Submit new /instructions/markdown-gfm.instructions.md for applying CommonMark + GitHub Flavoured Markdown spec (https://un5q021ctkzx6vwhy3c87d8.julianrbryant.com/gfm/).
I'll submit a PR to address this.
All will be optimized for reduced token usage.
