Steps use checkbox (`- [ ]`) syntax for tracking. + +**Goal:** Replace the sidebar "Giellie" web view with a MiniMax-powered chat agent that can read everything in WFDASH and perform any action except delete, with per-action user approval for changes. + +**Architecture:** A server-side agent loop (`giellie-agent.ts`) talks to MiniMax through the Anthropic SDK (config from the existing `ai_settings` row) and executes tools by calling the existing MCP route handler in-process (`giellie-mcp-bridge.ts`). A pure policy module classifies every tool as denied/read/write/confirm; writes pause the loop on an Approve/Reject card. Chats persist in one PB collection, `giellie_chats`. The browser talks to thin `/api/v1/giellie/*` routes over SSE. + +**Tech Stack:** Next.js 16.2 (webpack), React 19, PocketBase, `@anthropic-ai/sdk` (already installed), vitest + Testing Library, existing shadcn UI. + +**Spec:** `docs/superpowers/specs/2026-09-30-giellie-agent-design.md` + +## Global Constraints + +- Name is **Giellie** (two l's). Sidebar label **"Giellie Agent"**, route `/giellie`, API prefix `/api/v1/giellie`. +- Next.js here has breaking changes vs. training data: before writing route handlers read `node_modules/next/dist/docs/01-app/01-getting-started/15-route-handlers.md`. Dynamic route `params` is a **Promise** (`{ params }: { params: Promise<{ id: string }> }`). +- Data-layer rule: business logic in `src/lib/server/giellie-*.ts`, exposed through thin `src/app/api/v1/giellie/**/route.ts`. **Never import `@/lib/pb-helpers`.** +- No delete, ever: every `*.delete` tool is removed from Giellie's catalogue. Also removed: `ai_settings.get`, `ai_settings.update` (secret key), `files.fetch` and `quotes.get_pdf` (multi-MB base64). +- Default-deny classification: a tool is **read** only if explicitly allow-listed; everything else is a **write** needing approval. Email/PO sends are **always-confirm** (the trust toggle never covers them). +- Route auth: every Giellie route MUST call `getBrowserSessionUser(req)` (PB token in `Authorization: Bearer`). The app has no other server-side route auth and these routes hold `AGENT_API_KEY`. +- Limits: 10 files per message, 10 MB per file, 25 model turns per request, tool results truncated to 60 000 chars for the model and 8 000 chars in storage. +- **No test may call MCP write tools or PB against a live instance** (past incidents polluted the real quotes board). All tests mock `getAdminPocketBase` and the MCP route. +- **Do not run the migration script against live PB, and do not commit/push, unless Dave says so.** Work on branch `feat/giellie-agent`; the "Commit" steps below are to be executed only after Dave confirms he wants commits. +- Dev server port is **4001**. +- Match surrounding code style: terse doc-comment headers explaining *why*, no emoji, `"use client"` only on client components. + +## File Structure + +| File | Responsibility | +|---|---| +| `src/lib/giellie-types.ts` | Shared types: `Block`, `StoredMessage`, `PendingAction`, `GielieChat*` | +| `src/lib/giellie-sse.ts` | `GielieEvent` union, `encodeEvent`, `createEventParser` (server + client) | +| `src/lib/giellie-image.ts` | Client-only `downscaleImage` for camera/photo uploads | +| `src/lib/server/giellie-tool-policy.ts` | Denylist/allowlist/confirm lists, `classifyTool`, name mapping, `toAnthropicTools`, `truncateForModel` | +| `src/lib/server/giellie-mcp-bridge.ts` | `listMcpTools`, `callMcpTool` — in-process JSON-RPC into `src/app/api/mcp/route.ts` | +| `src/lib/server/giellie-system-prompt.ts` | `buildSystemPrompt({ now, userName })` | +| `src/lib/server/giellie-attachments.ts` | `buildUserTurn(text, files)` → stored + live blocks (text extraction / vision) | +| `src/lib/server/giellie-chat-store.ts` | PB CRUD for `giellie_chats`, storage compaction | +| `src/lib/server/giellie-agent.ts` | `runAgent`, `resolvePending`, `toModelMessages` (model client injected) | +| `src/lib/server/giellie-service.ts` | `startUserMessage`, `startDecision`, `getStatus` — glue, returns SSE streams | +| `src/lib/server/giellie-http.ts` | `errorResponse`, `sseResponse` helpers for routes | +| `src/lib/server/browser-session.ts` | (modify) return `name` too | +| `src/app/api/v1/giellie/{status,chats}/route.ts`, `chats/[id]/route.ts`, `chats/[id]/{messages,decision}/route.ts` | Thin handlers | +| `src/components/giellie/*` | `use-giellie.ts`, `message-list.tsx`, `approval-card.tsx`, `composer.tsx`, `chat-list.tsx` | +| `src/app/(app)/giellie/page.tsx` | Page shell | +| `src/components/sidebar.tsx` | (modify) rename + repoint nav item | +| `scripts/smoke/giellie-vision-probe.ts` | Image + tool-call probe against the configured endpoint | +| `scripts/migrations/2026-09-30-create-giellie-chats.ts` | Creates the collection (run by Dave) | + +--- + +### Task 1: MiniMax probe (gate — vision + tool calling on the configured endpoint) + +Establishes whether image blocks, tool calls and thinking blocks work through the Anthropic-compatible endpoint **before** building on it.
