Skink as your $EDITOR

Inside Skink: Ctrl+E, then help skink.

sh git config --global core.editor skink export EDITOR=skink VISUAL=skink

That covers commit messages and rebase lists, Ctrl+G in Claude Code and Codex, crontab -e, shell edit-command-line, kubectl edit and gh.

Files a tool hands its editor open **lean**: one buffer, no file tree, project scan, language server, git gutter, update check, session or recents. Skink picks it the way other editors do: git's own files by name (COMMIT_EDITMSG, MERGE_MSG, TAG_EDITMSG, SQUASH_MSG, git-rebase-todo, addp-hunk-edit.diff), and any file that belongs to no project. :mode says which and why.

| Key | Does | |---|---| | Ctrl+S | save | | Ctrl+Q | done (asks if unsaved) | | :cq | leave without saving and exit 1, so git aborts | | Alt+Shift+K | in a rebase list: cycle pick, reword, edit, squash, fixup, drop (:rebase VERB) | | Alt+Up / Alt+Down | reorder commits |

Commit messages get rulers at 50 and 72, dimmed # lines and a note when the subject passes 50 characters. Temp notes and prompts colour as Markdown and start with the cursor at the end.

skink --scratch FILE forces lean mode, skink --project FILE the full editor.

## From a Skink terminal

skink FILE in a Skink terminal tab opens a tab in that Skink instead of a second editor. Files a tool waits for (git's, an AI tool's) return when the tab closes: Ctrl+Q finishes (exit 0), :cq cancels (exit 1). Other files return at once. The shell gets SKINK_IPC and SKINK_IPC_TOKEN; env -u SKINK_IPC skink FILE edits inside the terminal instead.
