+# Config Editor Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Built-in `:config` provider that lets users browse and modify settings, toggle providers, select themes/engines, and manage profiles — all from within the launcher.
+
+**Architecture:** The config editor is a `DynamicProvider` that interprets the query text as a navigation path. `:config providers` shows toggles, `:config theme` lists themes, `:config profile dev modes` shows a mode checklist. Actions (toggling, setting values) use the existing `PluginAction` IPC flow which keeps the window open and re-queries, giving instant visual feedback. Config changes are persisted to `config.toml` via `Config::save()`.
+
+**Tech Stack:** Rust, owlry-core providers, toml serialization
+
+---
+
+## Key Design Decision: Query-as-Navigation
+
+Instead of submenus, the `:config` prefix scopes the search bar as navigation:
+
+```
+:config                          → category list
+:config providers                → provider toggles
+:config theme                    → theme selection
+:config engine                   → search engine selection
+:config frecency                 → frecency toggle + weight
+:config profiles                 → profile list
+:config profile dev              → profile actions (edit modes, rename, delete)
+:config profile dev modes        → mode checklist for profile
+:config profile create myname    → create profile action
+:config fontsize 16              → set font size action
+:config width 900                → set width action
+```
+
+Actions use `CONFIG:*` commands dispatched via `execute_plugin_action`. Since this returns `false` for `should_close`, the window stays open and re-queries — the user sees updated state immediately.
+
+## File Map
+
+| File | Action | Responsibility |
+|------|--------|----------------|
+| `crates/owlry-core/src/providers/config_editor.rs` | Create | ConfigProvider: query parsing, result generation, action execution |
+| `crates/owlry-core/src/providers/mod.rs` | Modify | Register ConfigProvider, extend action dispatch |
+| `crates/owlry-core/src/config/mod.rs` | Modify | Add helper methods for config mutation |
+
+---
+
+### Task 1: Create ConfigProvider skeleton and register it
+
+**Files:**
+- Create: `crates/owlry-core/src/providers/config_editor.rs`
+- Modify: `crates/owlry-core/src/providers/mod.rs`
+
+- [ ] **Step 1: Add module declaration**
+
+In `crates/owlry-core/src/providers/mod.rs`, add with the other module declarations:
+
+```rust
+pub(crate) mod config_editor;
+```
+
+- [ ] **Step 2: Create config_editor.rs with top-level categories**
+
+Create `crates/owlry-core/src/providers/config_editor.rs`:
+
+```rust
+//! Built-in config editor provider.
+//!
+//! Lets users browse and modify settings from within the launcher.
+//! Uses `:config` prefix with query-as-navigation pattern.

+}
+```
+
+- [ ] **Step 9: Verify compilation and tests**
+
+Run: `cargo test -p owlry-core config_editor`
+
+Note: tests that call `execute_action` will try `config.save()` which writes to disk. The save will fail gracefully (warns) in test environment since there's no XDG config dir — the toggle/set still returns true. If tests fail due to save, add `#[allow(dead_code)]` or mock the save path. Alternatively, since `Config::save()` returns a Result and the provider logs but ignores errors, this should be fine.
+
+Expected: All tests pass.
+
+- [ ] **Step 10: Commit**
+
+```bash
+git add crates/owlry-core/src/providers/config_editor.rs crates/owlry-core/src/providers/mod.rs
+git commit -m "feat(core): add built-in config editor provider
+
+Interactive :config prefix for browsing and modifying settings.
+Supports provider toggles, theme/engine selection, numeric input,
+and profile CRUD. Uses CONFIG:* action commands that persist to
+config.toml via Config::save()."
+```
+
+---
+
+### Task 2: Wire ConfigProvider into ProviderManager
+
+**Files:**
+- Modify: `crates/owlry-core/src/providers/mod.rs`
+- Modify: `crates/owlry-core/src/config/mod.rs` (if ProfileConfig is not public)
+
+The ConfigProvider needs to be:
+1. Registered as a built-in dynamic provider
+2. Its `execute_action` called from `execute_plugin_action`
+
+- [ ] **Step 1: Make Config wrap in Arc<RwLock> for shared ownership**
+
+The ConfigProvider needs mutable access to config. Currently `new_with_config` takes `&Config`. Change the daemon startup to wrap Config in `Arc<RwLock<Config>>` and pass it to both the ConfigProvider and the server.
+
+In `crates/owlry-core/src/providers/mod.rs`, in `new_with_config()`, after creating the config provider:
+
+```rust
+        // Config editor — needs shared mutable access to config
+        let config_arc = std::sync::Arc::new(std::sync::RwLock::new(config.clone()));
+        builtin_dynamic.push(Box::new(config_editor::ConfigProvider::new(config_arc)));
+        info!("Registered built-in config editor provider");
+```
+
+- [ ] **Step 2: Extend execute_plugin_action for built-in providers**
+
+In `execute_plugin_action`, after the existing native provider check, add:
+
+```rust
+        // Check built-in config editor
+        if command.starts_with("CONFIG:") {
+            for provider in &self.builtin_dynamic {
+                if let ProviderType::Plugin(ref id) = provider.provider_type() {
+                    if id == "config" {
+                        // Downcast to ConfigProvider to call execute_action
+                        // Since we can't downcast trait objects easily, add an
+                        // execute_action method to DynamicProvider with default impl
+                        return provider.execute_action(command);
+                    }
+                }
+            }
+        }
+```
+
+For this to work, add `execute_action` to the `DynamicProvider` trait with a default no-op:
+
+```rust
+pub(crate) trait DynamicProvider: Send + Sync {
+    fn name(&self) -> &str;
+    fn provider_type(&self) -> ProviderType;
+    fn query(&self, query: &str) -> Vec<LaunchItem>;
+    fn priority(&self) -> u32;
+
+    /// Handle a plugin action command. Returns true if handled.
+    fn execute_action(&self, _command: &str) -> bool {
+        false
+    }
+}
+```
+
+The ConfigProvider already has `execute_action` as an inherent method — just also implement it via the trait.
+
+- [ ] **Step 3: Ensure ProfileConfig is accessible**
+
+Check if `crate::config::ProfileConfig` is public. If not, add `pub` to its definition in `config/mod.rs`. The ConfigProvider needs to construct it for profile creation.
+
+- [ ] **Step 4: Run tests**
+
+Run: `cargo test -p owlry-core --lib`
+
+Expected: All tests pass (128+ existing + new config editor tests).
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add crates/owlry-core/src/providers/mod.rs crates/owlry-core/src/config/mod.rs
+git commit -m "feat(core): wire config editor into ProviderManager
+
+Register ConfigProvider as built-in dynamic provider. Extend
+execute_plugin_action to dispatch CONFIG:* commands. Add
+execute_action method to DynamicProvider trait."
+```
+
+---
+
+### Task 3: Update CLAUDE.md and README with config editor docs
+
+**Files:**
+- Modify: `README.md`
+
+- [ ] **Step 1: Add config editor section to README**
+
+In the README, in the Usage section (after Keyboard Shortcuts), add:
+
+```markdown
+### Settings Editor
+
+Type `:config` to browse and modify settings without editing files:
+
+| Command | What it does |
+|---------|-------------|
+| `:config` | Show all setting categories |
+| `:config providers` | Toggle providers on/off |
+| `:config theme` | Select color theme |
+| `:config engine` | Select web search engine |
+| `:config frecency` | Toggle frecency, set weight |
+| `:config fontsize 16` | Set font size (restart to apply) |
+| `:config profiles` | List profiles |
+| `:config profile create dev` | Create a new profile |
+| `:config profile dev modes` | Edit which modes a profile includes |
+
+Changes are saved to `config.toml` immediately. Some settings (theme, frecency) take effect on the next search. Others (font size, dimensions) require a restart.
+```
+
+- [ ] **Step 2: Commit**
+
+```bash
+git add README.md
+git commit -m "docs: add config editor usage to README"
+```
+
+---
+
+## Execution Notes
+
+### Task dependency order
+
+Task 1 is the bulk of the implementation. Task 2 wires it in. Task 3 is docs.
+
+**Order:** 1 → 2 → 3
+
+### What's NOT in this plan
+
+- **Hot-apply for theme** — would need the UI to re-trigger CSS loading after a CONFIG action. Can be added later by emitting a signal from the daemon or having the UI check a flag after `execute_plugin_action` returns.
+- **Profile rename via text input** — the current design supports `:config profile create <name>` but rename would need a two-step flow. Can be added later.
+- **Config file watching** — if the user edits `config.toml` externally, the ConfigProvider's cached `Arc<RwLock<Config>>` becomes stale. A file watcher could reload it. Deferred.

+# Built-in Providers Migration — Design Spec
+
+## Goal
+
+Move calculator, converter, and system from external `.so` plugins (owlry-plugins repo) to native providers compiled into `owlry-core`. Remove 3 plugin AUR packages (transitional), 4 meta AUR packages (already deleted). Update READMEs for both repos.
+
+## Architecture
+
+The 3 plugins currently use the FFI plugin API (`PluginVTable`, `PluginItem`, etc.) and are loaded as `.so` files by `NativePluginLoader`. As built-in providers, they become native Rust modules inside `owlry-core/src/providers/` implementing the existing `Provider` trait — same as `ApplicationProvider` and `CommandProvider`.
+
+No changes to the plugin system itself. External plugins continue to work via `.so` loading.
+
+## Components
+
+### New modules in owlry-core
+
+- `providers/calculator.rs` — port of owlry-plugin-calculator (231 lines, depends on `meval`)
+- `providers/converter/mod.rs` — port of owlry-plugin-converter entry point
+- `providers/converter/parser.rs` — query parsing (235 lines, no new deps)
+- `providers/converter/units.rs` — unit definitions + conversion (944 lines, no new deps)
+- `providers/converter/currency.rs` — ECB rate fetching (313 lines, depends on `reqwest` blocking + `dirs` + `serde`)
+- `providers/system.rs` — port of owlry-plugin-system (257 lines, no new deps)
+
+### New owlry-core dependencies
+
+- `meval` — math expression evaluation (currently optional behind `lua` feature, make required)
+- `reqwest` with `blocking` feature — ECB currency rate fetching (currently optional behind `lua`, make required)
+- `dirs` — already a dependency
+- `serde`/`serde_json` — already dependencies
+
+### Modified files
+
+- `owlry-core/src/providers/mod.rs` — register the 3 new providers in `ProviderManager`, honor config toggles, classify calculator+converter as dynamic providers
+- `owlry-core/Cargo.toml` — move `meval` and `reqwest` from optional to required
+- `owlry-core/src/config/mod.rs` — add `converter` config toggle (calculator and system already exist)
+
+### Provider classification
+
+- Calculator → dynamic (queried per-keystroke via `query()`)
+- Converter → dynamic (queried per-keystroke via `query()`)
+- System → static (populated at `refresh()`, returns fixed list of actions)
+
+## Provider Type IDs
+
+Built-in providers use `ProviderType::Plugin(String)` with fixed IDs to maintain backward compatibility with the UI highlighting and filter system:
+
+- Calculator: `ProviderType::Plugin("calc".into())`
+- Converter: `ProviderType::Plugin("conv".into())`
+- System: `ProviderType::Plugin("sys".into())`
+
+This ensures the UI's highlighting logic (`matches!(id.as_str(), "calc" | "conv")`) and CSS badge classes (`.owlry-badge-calc`, `.owlry-badge-sys`) continue to work without changes.
+
+## Config
+
+Existing toggles in `[providers]`:
+
+```toml
+[providers]
+calculator = true   # already exists
+system = true       # already exists
+converter = true    # new — add with default true
+```
+
+When a toggle is false, the provider is not registered in `ProviderManager` at startup.
+
+## Currency Conversion
+
+The converter's currency feature uses `reqwest` (blocking) to fetch ECB exchange rates with a 24-hour file cache at `~/.cache/owlry/ecb_rates.json`. If the HTTP fetch fails (no network, timeout), currency conversion silently returns no results — unit conversion still works. This matches current plugin behavior.
+
+## AUR Changes
+
+### Main repo (owlry)
+
+- `aur/owlry-core/PKGBUILD` — bump version
+- Remove `aur/owlry-meta-*` directories (4 dirs, already deleted from AUR)
+
+### Plugins repo (owlry-plugins)
+
+- Remove crates: `owlry-plugin-calculator`, `owlry-plugin-converter`, `owlry-plugin-system`
+- Remove AUR dirs: `aur/owlry-plugin-calculator`, `aur/owlry-plugin-converter`, `aur/owlry-plugin-system` from tracked files
+- Push transitional PKGBUILDs to the 3 AUR repos:
+
+```bash
+pkgname=owlry-plugin-calculator  # (and converter, system)
+pkgver=<last_version>
+pkgrel=99
+pkgdesc="Transitional package — calculator is now built into owlry-core"
+arch=('any')
+depends=('owlry-core>=<new_version>')
+replaces=('owlry-plugin-calculator')
+# No source, no build, no package body
+```
+
+### Conflict prevention
+
+When owlry-core gains built-in calculator/converter/system, users who have the old `.so` plugins installed will have both the built-in provider AND the `.so` plugin active — duplicate results. The daemon should detect this: if a built-in provider ID matches a loaded native plugin ID, skip the native plugin. Add this check in `ProviderManager` when registering native plugins.
+
+## README Updates
+
+### Main repo README
+
+- Package table: remove separate plugin entries for calculator, converter, system — note them as built-in to owlry-core
+- Remove meta package section entirely
+- Update install examples (no need to install calculator/converter/system separately)
+
+### Plugins repo README
+
+- Remove calculator, converter, system from plugin listing
+- Add note that these 3 are built into owlry-core
+
+## Testing
+
+- Port existing plugin tests directly — they test provider logic, not FFI wrappers
+- `cargo test -p owlry-core --lib` covers all 3 new providers
+- Add conflict detection test (built-in provider ID vs native plugin ID)
+- Manual verification: `= 5+3` (calc), `20F` (conv), `20 euro to dollar` (currency), system actions

+# Config Editor — Design Spec
+
+## Goal
+
+A built-in provider in owlry-core that lets users browse and modify their configuration directly from the launcher UI, without opening a text editor.
+
+## Scope
+
+### Editable settings (curated)
+
+**Provider toggles** (boolean):
+- applications, commands, calculator, converter, system
+- websearch, ssh, clipboard, bookmarks, emoji, scripts, files
+- media, weather, pomodoro
+- uuctl (systemd user units)
+
+**Appearance** (text input + selection):
+- theme (selection from available themes)
+- font_size (numeric input)
+- width, height (numeric input)
+- border_radius (numeric input)
+
+**Search** (text input + selection):
+- search_engine (selection: google, duckduckgo, bing, startpage, brave, ecosia)
+- frecency (boolean toggle)
+- frecency_weight (numeric input, 0.0–1.0)
+
+**Profiles** (CRUD):
+- List existing profiles
+- Create new profile (name input + mode checklist)
+- Edit profile (rename, edit modes, delete)
+
+### Not in scope
+
+- Weather API key / location (sensitive, better in config file)
+- Pomodoro durations (niche, config file)
+- Plugin disabled list (covered by provider toggles)
+- use_uwsm / terminal_command (advanced, config file)
+
+## UX Flow
+
+### Entry point
+
+Type `:config` or select the "Settings" item that appears for queries like "settings", "config", "preferences".
+
+### Top-level categories
+
+```
+:config →
+  ┌─ Providers          Toggle providers on/off
+  ├─ Appearance          Theme, font size, dimensions
+  ├─ Search              Search engine, frecency
+  └─ Profiles            Manage named mode sets
+```
+
+Each category is a submenu item. Selecting one opens its submenu.
+
+### Provider toggles
+
+```
+Providers →
+  ┌─ ✓ Applications     [toggle]
+  ├─ ✓ Commands          [toggle]
+  ├─ ✓ Calculator        [toggle]
+  ├─ ✓ Converter         [toggle]
+  ├─ ✓ System            [toggle]
+  ├─ ✗ Weather           [toggle]
+  ├─ ...
+```
+
+Selecting a row toggles it. The ✓/✗ prefix updates immediately. Change is written to `config.toml` and hot-applied where possible.
+
+### Appearance settings
+
+```
+Appearance →
+  ┌─ Theme: owl                    [select]
+  ├─ Font Size: 14                 [edit]
+  ├─ Width: 850                    [edit]
+  ├─ Height: 650                   [edit]
+  └─ Border Radius: 12             [edit]
+```
+
+**Selection fields** (theme): Selecting opens a submenu with available options. Current value is marked with ✓.
+
+**Text/numeric fields** (font size, width, etc.): Selecting a row enters edit mode — the search bar clears and shows a placeholder like "Font Size (current: 14)". User types a new value and presses Enter. The value is validated (numeric, within reasonable range), written to config, and the submenu re-displays with the updated value.
+
+### Search settings
+
+```
+Search →
+  ┌─ Search Engine: duckduckgo     [select]
+  ├─ Frecency: enabled             [toggle]
+  └─ Frecency Weight: 0.3          [edit]
+```
+
+Same patterns — selection for engine, toggle for frecency, text input for weight.
+
+### Profile management
+
+```
+Profiles →
+  ┌─ dev (app, cmd, ssh)           [submenu]
+  ├─ media (media, emoji)          [submenu]
+  └─ ➕ Create New Profile         [action]
+```
+
+**Select existing profile** → submenu:
+```
+Profile: dev →
+  ┌─ Edit Modes                    [submenu → checklist]
+  ├─ Rename                        [text input]
+  └─ Delete                        [confirm action]
+```
+
+**Edit Modes** → checklist (same as provider toggles but for the profile's mode list):
+```
+Edit Modes: dev →
+  ┌─ ✓ app
+  ├─ ✓ cmd
+  ├─ ✗ calc
+  ├─ ✗ conv
+  ├─ ✓ ssh
+  ├─ ...
+```
+
+Toggle to include/exclude. Changes saved on submenu exit (Escape).
+
+**Create New Profile**:
+1. Search bar becomes name input (placeholder: "Profile name...")
+2. User types name, presses Enter
+3. Opens mode checklist (all unchecked)
+4. Toggle desired modes, press Escape to save
+
+**Delete**: Selecting "Delete" removes the profile from config and returns to the profiles list.
+
+## Architecture
+
+### Provider type
+
+Built-in static provider in owlry-core. Uses `ProviderType::Plugin("config")` with prefix `:config`.
+
+### Provider classification
+
+**Static** — the top-level items (Providers, Appearance, Search, Profiles) are populated at refresh time. But it also needs **submenu support** — each category opens a submenu with actions.
+
+This means the config provider needs to handle `?SUBMENU:` queries to generate submenu items dynamically, and `!ACTION:` commands to execute changes.
+
+### Command protocol
+
+Actions use the existing plugin action system (`PluginAction` IPC request):
+
+- `CONFIG:toggle:providers.calculator` — toggle a boolean
+- `CONFIG:set:appearance.font_size:16` — set a value
+- `CONFIG:set:providers.search_engine:google` — set a string
+- `CONFIG:profile:create:dev` — create a profile
+- `CONFIG:profile:delete:dev` — delete a profile
+- `CONFIG:profile:rename:dev:development` — rename
+- `CONFIG:profile:mode:dev:toggle:ssh` — toggle a mode in a profile
+
+### Config persistence
+
+All changes write to `~/.config/owlry/config.toml` via the existing `Config::save()` method.
+
+### Hot-apply behavior
+
+| Setting | Hot-apply | Notes |
+|---------|-----------|-------|
+| Provider toggles | Yes | Daemon re-reads config, enables/disables providers |
+| Theme | Yes | UI reloads CSS |
+| Frecency toggle/weight | Yes | Next search uses new value |
+| Search engine | Yes | Next web search uses new engine |
+| Font size | Restart | CSS variable, needs reload |
+| Width/Height | Restart | GTK window geometry set at construction |
+| Border radius | Restart | CSS variable, needs reload |
+| Profiles | Yes | Config file update, available on next `--profile` launch |
+
+Settings that require restart show a "(restart to apply)" hint in the description.
+
+### Submenu integration
+
+The config provider uses the existing submenu system:
+- Top-level items have `SUBMENU:config:{category}` commands
+- Categories return action items via `?SUBMENU:{category}`
+- Actions execute via `CONFIG:*` commands through `execute_plugin_action`
+
+This keeps the implementation within the existing provider/submenu architecture without new IPC message types.
