From 4a2eb7ba31a811ea7a20fae45bb4614306767adb Mon Sep 17 00:00:00 2001 From: himanshu Date: Mon, 6 Apr 2026 14:01:27 +0530 Subject: [PATCH 1/6] feat: add Claude Agent SDK as alternative LLM backend MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add support for routing all LLM calls through the Claude Agent SDK (`@anthropic-ai/claude-agent-sdk`) as an alternative to the direct Anthropic API. This enables flat-rate billing via Claude Max subscription instead of pay-per-token pricing. - New `claude-sdk-service.ts` adapter translates Anthropic SDK params to Agent SDK `query()` calls, preserving the same response shape - `LLM_BACKEND` toggle in `anthropic-service.ts` (`anthropic` default, `claude-sdk` for Agent SDK) — env var or persisted config - Settings UI dropdown to switch between backends; API key field hidden when using Claude Code SDK - Streaming + extended thinking path in `draft-edit-learner.ts` gated by backend flag - Web search tool automatically translated from `web_search_20250305` to SDK's built-in `WebSearch` tool - Cost tracking preserved for both backends via `llm_calls` table Co-Authored-By: Claude Opus 4.6 --- package-lock.json | 16 +- package.json | 6 +- src/main/index.ts | 14 +- src/main/ipc/settings.ipc.ts | 17 +- src/main/services/anthropic-service.ts | 71 +++++ src/main/services/claude-sdk-service.ts | 357 ++++++++++++++++++++++ src/main/services/draft-edit-learner.ts | 77 +++-- src/renderer/components/SettingsPanel.tsx | 76 +++-- src/shared/types.ts | 1 + 9 files changed, 567 insertions(+), 68 deletions(-) create mode 100644 src/main/services/claude-sdk-service.ts diff --git a/package-lock.json b/package-lock.json index 176bff35..fd323a17 100644 --- a/package-lock.json +++ b/package-lock.json @@ -13,7 +13,7 @@ "src/extensions-private/*" ], "dependencies": { - "@anthropic-ai/claude-agent-sdk": "^0.2.37", + "@anthropic-ai/claude-agent-sdk": "^0.2.92", "@anthropic-ai/sdk": "^0.71.2", "@electron-toolkit/utils": "^4.0.0", "@floating-ui/dom": "^1.7.6", @@ -289,12 +289,12 @@ } }, "node_modules/@anthropic-ai/claude-agent-sdk": { - "version": "0.2.87", - "resolved": "https://registry.npmjs.org/@anthropic-ai/claude-agent-sdk/-/claude-agent-sdk-0.2.87.tgz", - "integrity": "sha512-WWmgBPxPhBOvNT0ujI8vPTI2lK+w5YEkEZ/y1mH0EDkK/0kBnxVJNhCtG5vnueiAViwLoUOFn66pbkDiivijdA==", + "version": "0.2.92", + "resolved": "https://registry.npmjs.org/@anthropic-ai/claude-agent-sdk/-/claude-agent-sdk-0.2.92.tgz", + "integrity": "sha512-loYyxVUC5gBwHjGi9Fv0b84mduJTp9Z3Pum+y/7IVQDb4NynKfVQl6l4VeDKZaW+1QTQtd25tY4hwUznD7Krqw==", "license": "SEE LICENSE IN README.md", "dependencies": { - "@anthropic-ai/sdk": "^0.74.0", + "@anthropic-ai/sdk": "^0.80.0", "@modelcontextprotocol/sdk": "^1.27.1" }, "engines": { @@ -316,9 +316,9 @@ } }, "node_modules/@anthropic-ai/claude-agent-sdk/node_modules/@anthropic-ai/sdk": { - "version": "0.74.0", - "resolved": "https://registry.npmjs.org/@anthropic-ai/sdk/-/sdk-0.74.0.tgz", - "integrity": "sha512-srbJV7JKsc5cQ6eVuFzjZO7UR3xEPJqPamHFIe29bs38Ij2IripoAhC0S5NslNbaFUYqBKypmmpzMTpqfHEUDw==", + "version": "0.80.0", + "resolved": "https://registry.npmjs.org/@anthropic-ai/sdk/-/sdk-0.80.0.tgz", + "integrity": "sha512-WeXLn7zNVk3yjeshn+xZHvld6AoFUOR3Sep6pSoHho5YbSi6HwcirqgPA5ccFuW8QTVJAAU7N8uQQC6Wa9TG+g==", "license": "MIT", "dependencies": { "json-schema-to-ts": "^3.1.1" diff --git a/package.json b/package.json index 01123c27..86481a5f 100644 --- a/package.json +++ b/package.json @@ -40,7 +40,7 @@ "eval": "npx tsx tests/evals/runner.ts" }, "dependencies": { - "@anthropic-ai/claude-agent-sdk": "^0.2.37", + "@anthropic-ai/claude-agent-sdk": "^0.2.92", "@anthropic-ai/sdk": "^0.71.2", "@electron-toolkit/utils": "^4.0.0", "@floating-ui/dom": "^1.7.6", @@ -87,10 +87,10 @@ "@types/react": "^18.3.12", "@types/react-dom": "^18.3.1", "@types/semver": "^7.7.1", - "@vitejs/plugin-react": "^4.3.4", - "autoprefixer": "^10.4.20", "@typescript-eslint/eslint-plugin": "^8.57.2", "@typescript-eslint/parser": "^8.57.2", + "@vitejs/plugin-react": "^4.3.4", + "autoprefixer": "^10.4.20", "electron": "^39.8.5", "electron-builder": "^25.1.8", "electron-vite": "^3.0.0", diff --git a/src/main/index.ts b/src/main/index.ts index fdc98369..700a6530 100644 --- a/src/main/index.ts +++ b/src/main/index.ts @@ -294,14 +294,20 @@ ipcMain.handle("default-mail-app:get-pending", () => { // Initialize database on startup const _db = initDatabase();

Now: - SetupWizard offers a backend choice (Claude Code SDK / Anthropic API) with radio buttons before asking for an API key - Selecting "Claude Code SDK" saves the backend config and skips the API key validation entirely - gmail:check-auth returns hasAnthropicKey=true when using claude-sdk backend, so existing users with that config skip the wizard too Co-Authored-By: Claude Opus 4.6 --- src/main/ipc/gmail.ipc.ts | 6 +- src/renderer/components/SetupWizard.tsx | 160 ++++++++++++++++++------ 2 files changed, 130 insertions(+), 36 deletions(-) diff --git a/src/main/ipc/gmail.ipc.ts b/src/main/ipc/gmail.ipc.ts index 70ed2ea3..32e3273d 100644 --- a/src/main/ipc/gmail.ipc.ts +++ b/src/main/ipc/gmail.ipc.ts @@ -2,6 +2,7 @@ import { ipcMain } from "electron"; import { GmailClient } from "../services/gmail-client"; import { saveEmail, getEmailIds, getInboxEmails, getEmail, saveAccount, getAccounts } from "../db"; import { getConfig } from "./settings.ipc"; +import { getLlmBackend } from "../services/anthropic-service"; import type { IpcResponse, DashboardEmail } from "../../shared/types"; import { DEMO_INBOX_EMAILS, DEMO_EXPECTED_ANALYSIS } from "../demo/fake-inbox"; import { createLogger } from "../services/logger"; @@ -67,7 +68,10 @@ export function registerGmailIpc(): void { try { const client = new GmailClient(); - const hasAnthropicKey = !!(process.env.ANTHROPIC_API_KEY || getConfig().anthropicApiKey); + // Claude SDK backend doesn't need an API key — the subscription handles auth + const hasAnthropicKey = + getLlmBackend() === "claude-sdk" || + !!(process.env.ANTHROPIC_API_KEY || getConfig().anthropicApiKey); return { success: true, data: { diff --git a/src/renderer/components/SetupWizard.tsx b/src/renderer/components/SetupWizard.tsx index 7453844f..e6be33c8 100644 --- a/src/renderer/components/SetupWizard.tsx +++ b/src/renderer/components/SetupWizard.tsx @@ -27,6 +27,9 @@ export function SetupWizard({ onComplete }: SetupWizardProps) { const [googleClientId, setGoogleClientId] = useState(""); const [googleClientSecret, setGoogleClientSecret] = useState(""); + // LLM backend choice + const [setupBackend, setSetupBackend] = useState<"anthropic" | "claude-sdk">("claude-sdk"); + // API key input const [apiKey, setApiKey] = useState(""); @@ -147,6 +150,34 @@ export function SetupWizard({ onComplete }: SetupWizardProps) { } }; + const handleSelectClaudeSdk = async () => { + setIsLoading(true); + setError(null); + + try { + // Save the backend choice — this makes hasAnthropicKey return true + const result = (await window.api.settings.set({ + llmBackend: "claude-sdk", + })) as IpcResponse; + if (result.success) { + const authResult = (await window.api.gmail.checkAuth()) as IpcResponse<{ + hasCredentials: boolean; + hasTokens: boolean; + hasAnthropicKey: boolean; + }>; + if (authResult.success && authResult.data.hasTokens) { + await enterExtensionsStep(); + } else { + setStep("oauth"); + } + } else { + setError(result.error ??
