From a8c51fd532f9d0c7d0682d02d3a438bb0ed29a43 Mon Sep 17 00:00:00 2001 From: Rishavraaj Date: Thu, 16 Jul 2026 02:40:36 +0530 Subject: [PATCH 01/19] feat(eve): port Claude Code agent pattern from gather MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Replace OpenAI with Claude Code (ai-sdk-provider-claude-code) - Add HMAC trusted-header auth (x-eve-principal, BETTER_AUTH_SECRET) - Add eve-principal sign/verify shared between backend + ai-agent - Add EveModule: proxy controller, credentials controller, chats CRUD - Add EveChat Prisma model + migration - Add same-origin Next.js proxy /api/eve/v1/[...path] - Add /api/chats GET/POST and /api/chats/[sessionId] GET - Rewrite ChatSurface with onSessionChange cursor + URL swap on first turn - Add fetchChatHistory for NDJSON resume replay - Update /chat and /chat/:id pages for new/resume flows - Update ChatsList to read from /api/chats (eve sessions) - Remove withEve() from next.config — ai-agent runs separately - Slim accounts to Claude + Codex only; remove getConnectionStatus - Fix resolveClaudeCredsJson to fall back when Claude not linked - Fix @Inject() on EveProxyController to bypass esbuild decorator metadata bug - Update env.ts: drop OPENAI_API_KEY, add BETTER_AUTH_SECRET + CLAUDE_CODE_OAUTH_TOKEN Co-Authored-By: Claude Sonnet 4.6 --- apps/ai-agent/agent/agent.ts | 14 +- apps/ai-agent/agent/channels/eve.ts | 76 ++-- apps/ai-agent/agent/instructions.md | 29 +- apps/ai-agent/agent/lib/env.ts | 7 +- apps/ai-agent/agent/lib/eve-principal.ts | 50 +++ apps/ai-agent/agent/lib/model/claude-code.ts | 191 ++++++++ apps/ai-agent/agent/lib/zuko-api.ts | 22 + apps/ai-agent/agent/lib/zuko-client.ts | 35 -- apps/ai-agent/agent/sandbox/fly-sprite.ts | 168 ++++++- apps/ai-agent/agent/sandbox/sandbox.ts | 9 +- apps/ai-agent/agent/tools/create_task.ts | 20 - apps/ai-agent/agent/tools/delete_task.ts | 15 - .../agent/tools/ensure-session-sprite.ts | 41 ++ apps/ai-agent/agent/tools/get_task.ts | 13 - apps/ai-agent/agent/tools/list_tasks.ts | 47 -- apps/ai-agent/agent/tools/update_task.ts | 29 -- apps/backend/src/accounts/accounts.module.ts | 10 + apps/backend/src/accounts/accounts.service.ts | 81 ++++ .../backend/src/accounts/connection-status.ts | 20 + .../accounts/dto/upsert-account-oauth.dto.ts | 35 ++ .../src/accounts/get-valid-claude-oauth.ts | 203 +++++++++ apps/backend/src/app/app.module.ts | 2 + apps/backend/src/eve/eve-chats.controller.ts | 85 ++++ apps/backend/src/eve/eve-chats.repository.ts | 56 +++ .../src/eve/eve-credentials.controller.ts | 59 +++ apps/backend/src/eve/eve-principal.guard.ts | 92 ++++ apps/backend/src/eve/eve-proxy-headers.ts | 23 + apps/backend/src/eve/eve-proxy.controller.ts | 200 +++++++++ apps/backend/src/eve/eve-target.service.ts | 16 + apps/backend/src/eve/eve.module.ts | 16 + apps/backend/src/eve/resolve-org.ts | 22 + apps/backend/src/utils/eve-principal.ts | 50 +++ apps/web/next.config.ts | 3 +- apps/web/src/app/(app)/chat/[chatId]/page.tsx | 410 ++---------------- apps/web/src/app/(app)/chat/page.tsx | 83 +--- .../src/app/api/chats/[sessionId]/route.ts | 32 ++ apps/web/src/app/api/chats/route.ts | 49 +++ .../web/src/app/api/eve/v1/[...path]/route.ts | 83 ++++ apps/web/src/components/Chat/ChatSurface.tsx | 221 ++++++++++ apps/web/src/components/Chat/ChatsList.tsx | 49 ++- .../src/components/Chat/fetchChatHistory.ts | 54 +++ libs/models/prisma/core.prisma | 20 + .../20260716000000_add_eve_chat/migration.sql | 22 + 43 files changed, 2025 insertions(+), 737 deletions(-) create mode 100644 apps/ai-agent/agent/lib/eve-principal.ts create mode 100644 apps/ai-agent/agent/lib/model/claude-code.ts create mode 100644 apps/ai-agent/agent/lib/zuko-api.ts delete mode 100644 apps/ai-agent/agent/lib/zuko-client.ts delete mode 100644 apps/ai-agent/agent/tools/create_task.ts delete mode 100644 apps/ai-agent/agent/tools/delete_task.ts create mode 100644 apps/ai-agent/agent/tools/ensure-session-sprite.ts delete mode 100644 apps/ai-agent/agent/tools/get_task.ts delete mode 100644 apps/ai-agent/agent/tools/list_tasks.ts delete mode 100644 apps/ai-agent/agent/tools/update_task.ts create mode 100644 apps/backend/src/accounts/accounts.module.ts create mode 100644 apps/backend/src/accounts/accounts.service.ts create mode 100644 apps/backend/src/accounts/connection-status.ts create mode 100644 apps/backend/src/accounts/dto/upsert-account-oauth.dto.ts create mode 100644 apps/backend/src/accounts/get-valid-claude-oauth.ts create mode 100644 apps/backend/src/eve/eve-chats.controller.ts create mode 100644 apps/backend/src/eve/eve-chats.repository.ts create mode 100644 apps/backend/src/eve/eve-credentials.controller.ts create mode 100644 apps/backend/src/eve/eve-principal.guard.ts create mode 100644 apps/backend/src/eve/eve-proxy-headers.ts create mode 100644 apps/backend/src/eve/eve-proxy.controller.ts create mode 100644 apps/backend/src/eve/eve-target.service.ts create mode 100644 apps/backend/src/eve/eve.module.ts create mode 100644 apps/backend/src/eve/resolve-org.ts create mode 100644 apps/backend/src/utils/eve-principal.ts create mode 100644 apps/web/src/app/api/chats/[sessionId]/route.ts create mode 100644 apps/web/src/app/api/chats/route.ts create mode 100644 apps/web/src/app/api/eve/v1/[...path]/route.ts create mode 100644 apps/web/src/components/Chat/ChatSurface.tsx create mode 100644 apps/web/src/components/Chat/fetchChatHistory.ts create mode 100644 libs/models/prisma/migrations/20260716000000_add_eve_chat/migration.sql diff --git a/apps/ai-agent/agent/agent.ts b/apps/ai-agent/agent/agent.ts index e6827b69..9f419dfc 100644 --- a/apps/ai-agent/agent/agent.ts +++ b/apps/ai-agent/agent/agent.ts @@ -1,12 +1,12 @@ import { defineAgent } from 'eve';
