+# Hammerspoon Configuration
+
+Language: Lua. Runtime: Hammerspoon (macOS automation framework).
+
+## Setup
+
+Config path is `~/.config/hammerspoon/init.lua`, set via:
+```
+defaults write org.hammerspoon.Hammerspoon MJConfigFile "~/.config/hammerspoon/init.lua"
+```
+
+Hammerspoon is a GUI app and does not inherit shell environment variables. Use `launchctl setenv` to propagate env vars.
+
+## Structure
+
+- `init.lua` — Entry point. App-switching hotkeys, config reload, and spoon loading.
+- `Spoons/` — Hammerspoon plugin packages (each is a `.spoon` directory with `init.lua`).
+
+## Hotkeys
+
+| Binding | Action |
+|---------|--------|
+| `cmd+alt+T` | Focus Ghostty |
+| `cmd+alt+B` | Focus Arc |
+| `cmd+alt+S` | Focus Slack |
+| `cmd+alt+M` | Focus Spotify |
+| `cmd+alt+Z` | Focus Zoom |
+| `cmd+alt+,` | Focus System Settings |
+| `alt+R` | Reload Hammerspoon config |
+| `alt+C` | Rewrite selected text in place (ClaudeRewriter) |
+| `alt+shift+C` | Show rewrite menu on selected text (ClaudeRewriter) |
+
+## ClaudeRewriter Spoon
+
+Path: `Spoons/ClaudeRewriter.spoon/`
+
+Rewrites selected text using the Anthropic Messages API. Reads the API key from `~/.config/gitlab-duo/a-key`.
+
+### Hotkey actions
+
+- `rewrite` — Sends selected text to Claude with the default system prompt, replaces selection with result.
+- `clipboard` — Same as rewrite but copies result to clipboard instead of pasting.
+- `menu` — Shows a popup context menu with prompt options loaded from disk. Selecting one rewrites the text in place.
+
+### Configurable properties
+
+- `apiKey` — Anthropic API key (required).
+- `model` — Model ID (default: `claude-sonnet-4-5`).
+- `systemPrompt` — Default system prompt used by the `rewrite` action.
+- `promptsPath` — Directory for menu prompts (default: `Spoons/ClaudeRewriter.spoon/prompts/`).
+- `alertDuration` — How long alerts display in seconds (default: 1.5).
+
+### Menu prompts
+
+Prompt files live in `Spoons/ClaudeRewriter.spoon/prompts/` as markdown files with YAML front matter. Menu order is determined by filename sort order (use numeric prefixes like `01-`, `02-`).
+
+Format:
+```markdown
+---
+title: Menu Item Title
+---
+The system prompt text sent to Claude.
+```
+
+Required front matter field: `title` (displayed in the menu). The markdown body is the system prompt.
+
+To add a new menu item, create a new `.md` file in the prompts directory.
+
+## Code style
+
+- Tabs for indentation.
+- Hammerspoon APIs are available via the global `hs` namespace.
+- Spoons follow Hammerspoon conventions: `init()`, `bindHotkeys()`, `start()`, `stop()`.
