Description of changes

Adds a new blog post about a worked-example Agent Skill for Great Tables, evaluated against a hand-built ground-truth corpus. Covers why table design decisions matter, what changes with the skill loaded vs. not (using a real before/after example), how the skill stays lightweight (one reference script plus two short reference files, no numbered flowchart), the corpus-wide numbers (comparator score, run-to-run consistency, token/cost usage vs. baseline), and a side-by-side check against a hand-authored ground truth for one prompt.

Also adds a minimal content/people/ profile for the author.

Screenshots or previews (if applicable)

See the Netlify preview link this PR generates for the full rendered post. The post's hero image (featured.png in the post folder) shows the core before/after comparison: the same prompt and data, once with no skill loaded and once with the skill attached.

Checklist

  • My code/content builds locally without errors or warnings.

Compares three great_tables skill designs from an internal eval harness
(gt-skill) against hand-built ground truths. The thin "house" design --
one worked reference script plus a short rules file, no flowchart --
comes out cheapest per table while landing within a point of the
top-scoring design and posting the tightest run-to-run consistency.

Reworks the earlier draft per feedback: drops the multi-skill comparison
in favor of presenting the skill on its own terms, swaps in a fresh
eval sweep (round 4) and a clearer example (gtcars top-10-by-country,
repeat 3 vs. baseline), combines the token and cost charts into one
side-by-side image, regenerates all charts with generic labels, and
rewrites the prose to read less like a comparison report.

- Replace prose with a shorter, less-technical walkthrough of the skill
- Swap old comparator/consistency/cost/ground-truth plots for the
  refreshed accuracy and usage plots from eval-results/house
- Reuse existing no-skill-table and skill-table screenshots as the
  good/bad table examples
- Regenerate index.md via quarto render
