# Create snippet Read these files from the project root in parallel: - `standards/snippets.md`: authoring conventions, invocation channels, use patterns - `standards/prose.md`: prose conventions for all generated text ## Steps 1. Confirm the slug and full content with the user before writing 2. Write the file to `snippets/<slug>.md` ## Guards - If `standards/snippets.md` is not present, stop: `❌ standards/snippets.md not found. Run aitk standards install first.` - If `snippets/` does not exist, stop: `❌ No snippets/ directory found.` ## After writing Remind the user: copy `snippets/<slug>.md` to the toolkit repo and place it in the correct category folder (`snippets/<category>/<name>.md`).
