# Repo Readme Assets — README + animated SVG header/footer Use this skill to **create or update a repository README and its visual header/footer** with local animated SVG assets. Zero external services: no capsule-render, no shields generators, no URL banners. Animation is SMIL only (`<animate>`, `<animateTransform>`) so it works inside `<img>` on GitHub without scripts or network requests. ## When to use - A repository needs a README with a header/footer banner (local animated SVG). - Major change happened and the README must reflect the current project state. - User asks for "readme header", "animated svg", "waving svg", "svg banner", "readme assets", "readme visual", "smil animation". ## Do NOT use - README is already current and the user did not request changes — do not "improve". - A single tiny fix (e.g. one badge) — edit directly, no skill needed. - For legal/community files (LICENSE, CONTRIBUTING, SECURITY) — use `repo-community-files`. - For description/topics/Pages/community-health — use `repo-metadata-health`. - For the social preview PNG — use `repo-social-preview`. ## Files - `SKILL.md` — this file - `scripts/generate_assets.py` — deterministic generation of `assets/header.svg` + `assets/footer.svg` - `scripts/extract_context.py` — auto-detect name/desc/stack/colors/username from git remote - `scripts/validate_svg.py` — validate SVG against skill rules (SMIL, mask, morphing) - `references/svg-animation.md` — full SVG animation spec + header/footer templa...
