+## PyPI Packaging Release (`shinka-evolve` 0.0.1)
+
+- Added a first PyPI distribution under the package name `shinka-evolve`.
+- Added GitHub Actions trusted publishing via `.github/workflows/pypi-release.yml`.
+- Bundled Hydra presets inside `shinka/configs/` so `shinka_launch` works from a PyPI install.
+- Preserved the original shorthand launch syntax such as `variant=...`, `task=...`, `database=...`, and `cluster=...`.
+- Added an artifact gate that rejects `.gitignore`-matched files from release outputs.
+- Updated README, getting-started docs, agent docs, and skill installation notes to prefer PyPI install and document `--config-dir` for user-defined presets.
+
 ## Highlights
 
 - Added a full async pipeline via `ShinkaEvolveRunner` for concurrent proposal generation and evaluation.
