# OneQuery Blog Images Create OneQuery blog thumbnails and article diagrams that match the existing landing-site image system. ## Core Workflow 1. Inspect the target post under `apps/landing/src/landing/blog/posts/` and the current image references. 2. Read `references/onequery-blog-image-system.md` before generating. 3. Use the built-in `image_gen` flow from the `imagegen` skill for generation. 4. Inspect the generated image with `view_image` before copying it into the repo. 5. Copy the selected generated image from `$CODEX_HOME/generated_images/...` into `apps/landing/public/images/blog/`. 6. Update the consuming post: - Thumbnail/social image: set `imageSrc` to `/images/blog/<file>.png`. - Section diagram: add `imageSrc`, `imageAlt`, `imagePlacement`, `images`, or `inlineImages` on the relevant section. 7. Validate references with `rg`, verify dimensions with `file`, and run `bunx turbo typecheck --json --filter @onequery/landing` after TypeScript changes. ## Hard Rules - Do not leave project-referenced images only under `$CODEX_HOME/generated_images`. - Do not overwrite existing image assets unless the user asked to replace them. - Keep thumbnail diagrams simple and centered with at least 1/5 canvas width empty on every edge. - Avoid readable text in thumbnails. Use icons, arrows, dots, tiles, and abstract diagram components instead. - For article diagrams, allow short uppercase module labels only when they improve clarity. - Use `assets/diagram-design-system.p
