Vibe Seller - Claude Code Context

What & Why

Team collaboration platform for e-commerce store automation. Users create browser-automation tasks organized by store, executed via browser-use CLI (Chrome/Ziniao) with real-time SSE streaming.

Tech Stack

• Backend: Python 3.11+ / FastAPI / SQLAlchemy 2.0 async / SQLite (~/.vibe-seller/data/vibe_seller.db) / SSE
• Frontend: React 19 / TypeScript / Vite / Tailwind CSS 4 / react-i18next
• Browser: browser-use CLI with pluggable backends (Chromium engine)

Key Conventions

• Component-based frontend: App.tsx (state + layout shell) delegates to views/ (TasksView, EventsView, WorkspaceView, SettingsView), components/ (Sidebar, modals, UI primitives), hooks/ (useSSE), with shared types.ts and api.ts
• Optional integration bundles (e.g. Google Workspace) install per-user via Settings → Integrations; see app/workspace/gws_integration.py.
• Pluggable browser backends in app/browser/ (base.py defines interface); multi-client CDP proxy in cdp_mux_proxy.py for concurrent per-store tasks
• AI agent abstraction in app/ai/ (AIAgentBackend ABC, ClaudeCodeBackend impl)
• System prompts in app/prompts/*.md — loaded once at import via app/prompts/__init__.py
• Tasks auto-execute on creation in auto mode (default, plan_mode=false): bypassPermissions, PENDING → RUNNING → COMPLETED. Opt-in plan mode (plan_mode=true): agent plans in read-only mode, user reviews, then executes (PENDING → DESIGNING → PLANNED → RUNNING → COMPLETED). Toggle via Auto/Plan switch in task detail footer. Non-store tasks always use plan mode. Plan-mode schedules author the plan once at creation via an is_plan_only=True Task (user reviews, plan is frozen on Schedule.plan, plan_status=ready); each subsequent fire copies the frozen plan and skips planning. See app/plan_states.py + docs/subsystems.md.
• JWT cookie auth (httpOnly, 7-day expiry)
• UUIDs for all primary keys
• API routes prefixed with /api/
• i18n translations in frontend/src/i18n/locales/{en,zh}/
• Ad tasks declare their kind + scope before working, and are held to what they declared. The ad skills tell the agent to call vibe_seller_declare_ad_task (kind ∈ audit/create/execute/investigate, scope = combos/campaigns/products) before touching a browser. That declaration — not the shape of the report — decides how much marketplace coverage the completeness gate demands and whether the user gets a review console. Declarations are append-only and a new one needs a new USER message, so an agent cannot re-declare around a gate. Never reintroduce an "is this an audit?" heuristic over the agent's own output: that is what let a two-campaign task be told it owed five marketplaces, which it satisfied by transcribing the previous week's report. See app/ai/ad_declaration.py and docs/api.md.
  • The in-turn ratchet (ad_declaration.supersedes) — a re-declaration inside the same turn may never widen reach and may never shed an obligation. Two moves qualify: narrowing at the same kind (recording campaign ids you could only learn by enumerating), and correcting investigate → audit at the same-or-narrower scope. The upgrade is legal precisely because it adds what the phase owes — coverage plus a console — so it is not an escape hatch; audit → investigate and every other pair stay refused. Without it, a phase that under-declared had no move but to delete the recommendations the user asked for.
  • Scope of the guarantee — the requirement rides on the ad skills: declaration_gaps lives inside ad_completeness_review, which those skills register via gates: frontmatter, so a run that never loads an ad skill can finish without declaring. That is the fail-safe direction and is intentional: no declaration → no console → nothing over-wide is offered. Do not "fix" it by inferring a declaration from the report — that is the heuristic above, wearing a new hat. Within that gate, the checks that compare a report against an existing declaration are not so limited, and must not be scoped to incidental formatting: the "investigate may not hand out decisions" check deliberately runs whether or not the report carries ## <platform> <CC> sections, because conditioning it on headings let a bid review declared investigate deliver bid changes with no console and no gap raised.
• Agents write to stores/ and knowledge/ via MCP vibe_seller_write_workspace_file (not the built-in Write tool — it can't write through workspace symlinks; see docs/workspace.md)
