When asked to write a blog post, follow these steps:

## Important Constraint
This skill does not provide a `scripts/` directory.
Do not call `run_skill_script` for this skill.
Use `load_skill_resource` for `references/style-guide.md`, then write content directly.

## Step 1: Structure
Use `load_skill_resource` to read `references/style-guide.md` for the writing style rules.
