+# Fish shell + Starship prompt setup on Nobara FC43
+
+## Summary
+Migrated interactive shell from zsh to fish on Nobara FC43 (Linux 6.18 kernel). Full setup for fish + Starship with bash-for-scripts hybrid strategy.
+
+## Installation
+- Fish installed via `dnf`
+- Set as default login shell: `chsh -s /usr/bin/fish`
+- Starship installed via `dnf` (`starship` package in `nobara-updates` repo)
+
+## Fish config (`~/.config/fish/config.fish`)
+```fish
+if status is-interactive
+    set -x SHELL /bin/bash   # Keep Claude Code and scripts on bash
+    starship init fish | source
+end
+```
+
+Key detail: `set -x SHELL /bin/bash` is set inside `config.fish` so Claude Code's Bash tool, shebang scripts, and any tool that respects `$SHELL` continue using bash — not fish (which is POSIX-incompatible).
+
+## Starship config (`~/.config/starship.toml`)
+- AWS module disabled (not used)
+- `git_commit` disabled (too noisy)
+- `git_metrics` enabled with `only_nonzero_diffs = false` (always shows +N -N stats)
+
+## Compatibility Notes
+- Fish is POSIX-incompatible: no `export`, different variable syntax, different conditionals
+- Scripts with `#!/bin/bash` shebangs are completely unaffected
+- Claude Code shell execution unaffected due to the SHELL override
+- Starship works identically across fish, zsh, and bash — config is shell-agnostic
