create_post.ps1	Added categories/tags placeholders to template with inline comments and basic reminder message

create_post.sh:47

• The grep filter grep -v '^authors' won't correctly exclude author names because list items under the authors field don't start with 'authors' - they start with spaces. This command will include author names in the output along with categories and tags. Consider using a more robust filtering approach, such as grep -A 100 'tags:' docs/posts/*/index.md docs/posts/*/*/index.md docs/posts/*/*/*/index.md | grep ' - ' | sort -u to specifically extract only the tags section.

The inline comments "(use existing categories when possible)" and "(use existing tags when possible)" should be removed from the placeholders. According to previous feedback that was marked as fixed, these inline comments should not be present. The shell script version (create_post.sh) correctly uses plain placeholders without inline comments and relies on the reminder message below to provide guidance. Remove the inline comments to match the create_post.sh format and maintain consistency between the two scripts.

Suggested change

	- CATEGORY_HERE (use existing categories when possible)
	tags:
	- TAG_HERE (use existing tags when possible)
	- CATEGORY_HERE
	tags:
	- TAG_HERE

If there can be more than one category/tag, it would be helpful to document that as a YAML comment, e.g.
# use existing categories and tags when possible, in YAML list format.

Perhaps in a future commit we can have the script list the current known tags and categories.

@normanlorrain the existing tags and categories are listed in the README. I'm not sure that is the best place for them, but they are easy to update using a clanker (coding agent).

I like your idea of a comment. I'll update the PR with that change and see what you think.

Uh oh, my editor "cleaned up" the whitespace. I only added the last two lines.

I restored the file, and re-added my changes.

@mrbiggred not sure if it's bad form to add a file to a PR.

This script mines the existing documents to pull out the tags and categories, so they can be displayed in the "create_post" scripts.
