 `/skill-audit` does not use an LLM and never edits skills.
 
-`/skill-improve` uses `google/gemini-2.5-flash` through Pi's model registry to generate a proposal/diff only. It never edits skills. Review the proposal and explicitly ask Pi to apply changes if you approve.
+`/skill-improve` prefers `google/gemini-3-flash-preview`, falls back to `google/gemini-2.5-flash`, then the current model. It uses a fixed rubric inspired by skill optimization workflows: completeness, actionability, conciseness, robustness, invocation clarity, safety/approval, and validation. It generates a proposal/diff only and never edits skills. Review the proposal and explicitly ask Pi to apply changes if you approve.

+`/skill-manager` opens quickly by listing discovered skills without auditing them all. The skill picker uses a scrollable TUI list with compact labels, prefix filtering by typing, symlink badges, duplicate-count badges, and paths in descriptions. Pick a skill, then choose `Run audit`, `Generate improve proposal`, `Open latest proposal in nvim`, or `Show paths`. `Run audit` keeps the persistent widget compact and points to `/skill-audit <name>` for full details. After generating an improve proposal, the UI asks whether to open the proposal in Neovim. Symlinked skill directories are followed during discovery; path views and improve reports show the resolved source path to make future approved edits target the source.
