+# Fetch Models 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:** Add an "Aktualisieren" button next to the model dropdown in settings that fetches the 3 newest Claude models from the Anthropic API and repopulates the dropdown.
+
+**Architecture:** `ClaudeClient` gains a `fetchModels()` method (reusing existing `requestUrl`/`headers` patterns). `SettingsTab` captures the `DropdownComponent` and `ButtonComponent` references, wires the button to call `fetchModels`, and rebuilds the dropdown on success.
+
+**Tech Stack:** TypeScript, Obsidian plugin API (`requestUrl`, `Setting`, `DropdownComponent`, `ButtonComponent`, `Notice`), Anthropic Models API (`GET /v1/models`)
+
+---
+
+## File Map
+
+| File | Change |
+|---|---|
+| `src/ClaudeClient.ts` | Add `fetchModels(apiKey)` method |
+| `src/SettingsTab.ts` | Update imports; refactor "Modell" `Setting` to capture dropdown + add button |

+# Fetch Models Design
+
+**Date:** 2026-03-27
+**Status:** Approved
+
+## Summary
+
+Add an "Aktualisieren" button to the Model setting in the settings tab. When clicked, it fetches the 3 newest Claude models from the Anthropic Models API and updates the dropdown. Falls back to the hardcoded `MODELS` list if the request fails or returns no models.
+
+## ClaudeClient changes
+
+Add a new method `fetchModels(apiKey: string): Promise<{id: string, name: string}[]>` to `ClaudeClient`.
+
+- URL: `"https://api.anthropic.com/v1/models"` — inline string or a separate private constant; **do not use or modify `baseUrl`** (which points to `/v1/messages`)
+- Call `requestUrl` with `throw: false` (same pattern as `streamChat`/`chat`) and `this.headers(apiKey)`
+- Response shape: `{ data: [{ id: string, created: number, display_name: string, ... }] }`
+- Throw on `response.status >= 400` with the response text
+- If `data` is empty, throw an error ("No models returned") — do not return an empty array
+- Sort `data` descending by `created`, take top 3
+- Return `{ id, name: id }` for each — use `id` as the display name (not `display_name`). Note: fetched entries will show raw IDs (e.g. `claude-opus-4-6`) while hardcoded `MODELS` show human-friendly names (e.g. `"Claude Opus 4.6 (Stärkste)"`). This is intentional — keeps the implementation simple and avoids relying on API-provided display strings.
+
+## SettingsTab changes
+
+**Import addition:** Add `Notice, ButtonComponent, DropdownComponent` to the `import { ... } from "obsidian"` line.
+
+Convert the existing "Modell" `Setting` to capture both the `DropdownComponent` and `ButtonComponent` references by chaining `addDropdown()` and `addButton()` on the same `Setting` instance:
+
+```typescript
+let modelDrop: DropdownComponent;
+let refreshBtn: ButtonComponent;
+
+new Setting(containerEl)
+  .setName("Modell")
+  .setDesc("Welches Claude-Modell verwenden?")
+  .addDropdown((drop) => {
+    modelDrop = drop;
+    for (const m of MODELS) drop.addOption(m.id, m.name);
+    drop.setValue(this.plugin.settings.model).onChange(async (value) => {
+      this.plugin.settings.model = value;
+      await this.plugin.saveSettings();
+    });
+  })
+  .addButton((btn) => {
+    refreshBtn = btn;
+    btn.setButtonText("Aktualisieren").onClick(async () => { /* see click flow */ });
+  });
+```
+
+**Click flow:**
+1. Capture current value: `const prev = modelDrop.getValue()`
+2. `refreshBtn.setDisabled(true)` and `refreshBtn.setButtonText("...")`
+3. In a try/catch/finally:
+   - **try:** Call `this.plugin.claude.fetchModels(this.plugin.settings.apiKey)`
+   - On success: clear dropdown with `modelDrop.selectEl.empty()`, repopulate via `modelDrop.addOption(id, name)` for each fetched model, then set value to `prev` if it exists among the fetched ids, otherwise the first fetched id; save via `this.plugin.settings.model = modelDrop.getValue(); await this.plugin.saveSettings()`
+   - **catch:** `new Notice("Modelle konnten nicht geladen werden: " + err.message)` — dropdown is **not** modified on error (hardcoded options remain)
+   - **finally:** `refreshBtn.setDisabled(false)` and `refreshBtn.setButtonText("Aktualisieren")`
+
+**Fallback:** The hardcoded `MODELS` array in `SettingsTab.ts` is unchanged and remains the initial population of the dropdown on every settings open.
+
+## Data flow
+
+```
+[Aktualisieren button click]
+  → capture prev = modelDrop.getValue()
+  → disable button, show "..."
+  → this.plugin.claude.fetchModels(apiKey)  [throw: false, separate URL]
+    → throw if status >= 400 or data empty
+    → sort by created desc, take 3
+    → return [{id, name: id}]
+  → clear selectEl, repopulate, restore selection
+  → save model to settings
+  → finally: restore button
+```
+
+## Error handling
+
+| Scenario | Behaviour |
+|---|---|
+| No API key (401) | Notice shown; dropdown unchanged |
+| Network failure | Notice shown; dropdown unchanged |
+| Empty `data` array | Treated as error; Notice shown; dropdown unchanged |
+| Fewer than 3 models returned | Take all returned (no error) |
+
+## Out of scope
+
+- Persisting fetched models across restarts
+- Auto-fetching on settings open or plugin startup
+- Configurable count of models to show
+- Updating `DEFAULT_SETTINGS.model` after a fetch
