📚 Description

Make skilld's original research readable and reproducible, with an authoring guide as the next action. Adds a study of 12,141 Skills with accessible charts, repository and duplicate weighting, source downloads, dataset metadata, and a D1 snapshot of the findings. Also fixes the shared text component used to render branded social cards.

GitHub merged this pull request.

• Logged (40/100): The PR description image and both author verification screenshots (desktop chart, mobile layout) could not be visually inspected, so chart rendering, mobile table behavior, and overflow claims rest solely on the author's comment. View code Optional follow-up: Have a human reviewer inspect the three PNGs, or replace them with text/HTML evidence of the rendered charts before merge.
  • Ask an agent to verify and fix this finding
• Logged (25/100): The claimed change to the shared OG text component behind every page's branded social card is completely unreviewed in this pass; if it alters shared rendering, all site OG images change silently. View code Optional follow-up: Name the changed component file in the PR description and re-run Review with diff evidence available (for example by excluding the binary research exports from diff computation).
  • Ask an agent to verify and fix this finding
• Logged (20/100): No automated guard ties the committed measurements.json bytes to the recorded hash that the article's reproducibility claim rests on. View code Optional follow-up: Add the hash assertion as a unit test (and optionally a CI step) so a regenerated summary from edited inputs cannot ship self-consistently.
  • Ask an agent to verify and fix this finding
• Logged (10/100): The chart component duplicates public snapshot data into the page chunk and requires a code edit for any future snapshot; a snapshot-agnostic module would decouple them. View code Optional follow-up: Move the imports behind a small shared module keyed by snapshot id, or fetch the JSON at runtime from its public URL.

Agent verification: inspected desktop, mobile, and dark-mode charts in the built Cloudflare Worker. The research route renders charts and dataset metadata in server HTML, with a canonical URL and sitemap entry. Checked all 328,916 exported CSV cells against JSON, independently recalculated repository weighting, and queried the migrated local D1 snapshot. The branded social card returns a valid PNG.

Post-merge production verification for b202672: the site deploy job passed. The article serves the revised prose with the expected canonical and Dataset metadata. JSON, CSV, the authoring guide, and branded PNG return 200. The page has no JavaScript errors or horizontal overflow at 390px. The production D1 snapshot contains 12,141 Skills across 2,297 repositories, with the published measurement hash.
