Motivation

Readers familiar with AI or programming may still know nothing about the author's project. Clarify the existing audience-background guidance so technical posts intended for a broader audience open with a concrete behavior, result, or scenario while retaining useful technical depth.

Changes

• Update the audience-background paragraph in skills/x-content/references/writing.md.
• Add evaluation 25 for AI-familiar readers who do not know the author's classifier project, covering a concrete opening, retained evidence, and a screenshot suggestion grounded in the supplied material.
• Add evaluation 26 for an explicitly expert audience, checking that familiar concepts stay technical and do not gain unnecessary introductory explanations or visuals.

No runtime code, public API, compatibility-surface, or evaluation JSON schema changes.

Validation

• git apply --check and application of the supplied patch against 06d0014dcab38949781df61371f4a2bca627d765: passed.
• uv run --python 3.12 python -m unittest discover -s tests -v: 77 tests passed.
• uv run --python 3.12 python scripts/update_readme_skills.py --check: passed.
• Skill Creator quick_validate.py skills/x-content, using Python 3.12 and PyYAML: passed.
• gh skill publish --dry-run: passed with advisory repository-security warnings.
• JSON structure check: all 24 cases have unique IDs/names and the expected fields; the original 22 cases are unchanged, and only IDs 25 and 26 were added.
• git diff --check: passed.

Model-driven evaluations and a before/after behavioral comparison were not run. These structural checks do not establish improved model behavior or engagement.
