# TokenSense Progress and Next Steps

## Completed

### Phase 1 -- Documentation

- [CLAUDE.md](CLAUDE.md) -- project overview, architecture, conventions
- [docs/BACKEND_PLAN.md](docs/BACKEND_PLAN.md) -- step-by-step backend build guide
- [docs/FRONTEND_PLAN.md](docs/FRONTEND_PLAN.md) -- per-page frontend specs with Pencil.dev prompts

### Phase 2 -- Backend (all code written)

- [.env.example](.env.example) -- environment variable template
- [backend/utils/auth.py](backend/utils/auth.py) -- `X-API-Key` header validation
- [backend/utils/db.py](backend/utils/db.py) -- SQLite init, `log_query`, `get_stats`, `get_summary`
- [backend/agents/query_agent.py](backend/agents/query_agent.py) -- embeddings via OpenRouter, task classification, LRU cache
- [backend/agents/retrieval_agent.py](backend/agents/retrieval_agent.py) -- Actian VectorAI DB `AsyncCortexClient` integration
- [backend/agents/context_optimizer.py](backend/agents/context_optimizer.py) -- deduplication, re-ranking, token budget truncation
- [backend/agents/routing_agent.py](backend/agents/routing_agent.py) -- model selection + OpenRouter/Gemini API calls
- [backend/agents/telemetry_agent.py](backend/agents/telemetry_agent.py) -- cost calculation, SQLite persistence
- [backend/routers/index_router.py](backend/routers/index_router.py) -- `POST /index`
- [backend/routers/ask_router.py](backend/routers/ask_router.py) -- `POST /ask` (full pipeline)
- [backend/routers/optimize_router.py](backend/routers/optimize_router.py) -- `POST /optimize`
- [backend/routers/stats_router.py](backend/routers/stats_router.py) -- `GET /stats`
- [backend/main.py](backend/main.py) -- FastAPI app with CORS, lifespan, all routers wired
- [backend/requirements.txt](backend/requirements.txt) -- pinned to installed versions
- All Python dependencies installed (`fastapi`, `uvicorn`, `httpx`, `python-dotenv`, `pydantic`, `aiosqlite`, `actiancortex`)
- Actian VectorAI DB Docker image onboarded

### Infrastructure

- `.gitignore` -- populated with `.env`, `__pycache__/`, `backend/data/`, `node_modules/`, `.next/`, etc.
- `.env` -- created with real API keys

---

## Not Started

### Phase 3 -- Frontend

No `frontend/` directory exists yet. Per [docs/FRONTEND_PLAN.md](docs/FRONTEND_PLAN.md), this involves:

- Initialize Next.js 14 project with TypeScript + Tailwind + App Router
- Install shadcn/ui, recharts, lucide-react
- Create typed API client at `frontend/lib/api.ts`
- Build 4 pages: Landing (`/`), Playground (`/playground`), Dashboard (`/dashboard`), Docs (`/docs`)

### Phase 4 -- CLI

No `cli/` directory exists. Typer-based CLI with `init`, `index`, `ask`, `stats` commands.

### Phase 5 -- Integration and Dev Scripts

No `dev.sh`, no README content, `.gitignore` is empty.

---

## Immediate Action Items (before moving to Phase 3)

These are pre-flight tasks to validate the backend works end-to-end before building the frontend on top of it.
