 # Multi-Agent RAG
 
+> **Live demo:** [multi-agent-rag.olegedly.com](https://multi-agent-rag.olegedly.com/)
 A config-driven multi-agent research system with pgvector RAG, MCP tool servers, and a LangChain agent pipeline. Answers are grounded in curated knowledge bases (corpora), each scoped to a single corpus with route-based isolation.
 
 ## Quick Start
 
+First, create your config:
+
+```bash
+cp .env.example .env
+# Then edit .env with your API keys
+```
+
+Then start the dev environment:
+
 ```bash
 ./dev.sh
 ```

 The system is **corpus-scoped**: each conversation binds to one corpus from start to finish. Every retrieval carries the active `corpus_id`. Adding a new knowledge base is an ingestion + config task.

+# Grill Me Results

+
+## Plan
+
+let's carefully plan the changes. so I've found that @docker-compose.coolify.yml is purely a note for how to deploy on coolify, I copy/paste it into the coolify web ui, there's no other usage. and then we have 2 files: @docker-compose.base.yml and @docker-compose.dev-override.yml ; these are safe to merge into one, because we don't in fact ever use them separately. so the way @dev.sh calls them needs to become the baseline docker-compose.yml ; clear?
+
+## Shared Understanding
+
+AC #8 (docker compose up from scratch) redesigned via /grill-me interview. The plan: merge docker-compose files into a single docker-compose.yml with only the db service, delete the unused base.yml/dev-override.yml, create .env.example, add migrate_db() to backend startup lifespan, update dev.sh to call plain 'docker compose up -d', and update the AC text and tick box in the issue.
+
+## Questions and Answers
+
+### 1. What's the target mode for the merged docker-compose.yml — dev (native-like hot-reload) or "from scratch" production-like (everything in containers)?
+
+**Recommended answer:** We need to merge base.yml + dev-override.yml into one docker-compose.yml that works for both: dev.sh would just run `docker compose up -d db` (backend/frontend native), AND `docker compose up --profile production` would start all containers for the "clone → .env → docker compose up" experience. But the AC #8 demands the latter work seamlessly.
+
+**User answer:** _(not recorded)_
+
+**Status:** open
+
+**Notes:** Tension: dev.sh uses containers only for DB (backend/frontend native), but AC #8 requires everything in containers from scratch. The merged compose needs to serve both.
+
+### 2. Are the docker-compose files used for building deployable Docker images?
+
+**Recommended answer:** No. The CI/CD workflow at .github/workflows/deploy.yml builds images directly from Dockerfiles (backend/Dockerfile, frontend/Dockerfile) and pushes to GHCR. The compose files are purely for local development (dev.sh spins up the DB container) and the coolify.yml is a copy-paste note for the Coolify web UI.
+
+**User answer:** No — compose files are not used for building deployable images; CI/CD uses Dockerfiles directly.
+
+**Status:** resolved
+
+### 3. Should AC #8 change to reflect the actual dev workflow instead of the strict "docker compose up from scratch"?
+
+**Recommended answer:** Yes. Change it to: "Developer setup works: clone → copy .env.example → ./dev.sh starts DB in Docker, backend (hot-reload) and frontend (Vite HMR) natively. No manual steps beyond configuring .env."
+
+**User answer:** Yeah, let's make the AC reflect what we already do in practice
+
+**Status:** resolved
+
+**Notes:** Compose files are merged into one docker-compose.yml (base + dev-override combined). dev.sh uses it the same way, just without -f flags. The criterion tracks the real dev workflow.
+
+### 4. The merged docker-compose.yml will have db, backend, and frontend services. dev.sh starts only `db`. But a fresh clone also needs DB tables and seeded corpus data to be useful. Should the backend auto-migrate and auto-seed on startup, or are those separate concerns from this AC?
+
+**Recommended answer:** They're separate concerns. The AC says "docker compose up from scratch works with only .env file." The merged compose + dev.sh handles the container/native startup. DB migration and seeding are part of the seed workflow (scripts/seed_knowledge_base.py), not the compose refactor. But we should mention in the README that after first ./dev.sh, you run `uv run scripts/seed_knowledge_base.py --all`.
+
+**User answer:** _(not recorded)_
+
+**Status:** needs-codebase-check
+
+**Notes:** Need to check if the backend startup currently fails gracefully when DB tables don't exist, or if it crashes. If it crashes, we may need to at least call migrate_db() on startup.
+
+### 5. Should merged compose + .env.example also add auto-migration (calling migrate_db() on backend startup via the lifespan), or is that a separate concern?
+
+**Recommended answer:** Separate concern. The AC is about startup mechanics (merge compose files, create .env.example). DB migration and seeding remain the existing workflow: `uv run scripts/seed_knowledge_base.py --all`. However, to make the "from scratch" experience not immediately fail, we could add migrate_db() to the backend lifespan — it's idempotent and takes <100ms. Worth adding as a good-faith step.
+
+**User answer:** _(not recorded)_
+
+**Status:** open
+
+**Notes:** Backend starts fine without tables (lazy DB connections via RAG tools). First chat query would error on missing tables. migrate_db() is safe to call on every startup (idempotent).
+
+### 6. Should migrate_db() be called on every backend startup via the lifespan?
+
+**Recommended answer:** Yes. migrate_db() is fully idempotent (~100ms no-op when tables exist). Adding it to the backend lifespan means a fresh clone with an empty DB gets tables created automatically, preventing SQL errors from leaking to the agent on first chat. Data seeding remains a separate manual step.
+
+**User answer:** Yes, sounds reasonable — add migrate_db() to backend startup lifespan.
+
+**Status:** resolved
+
+### 7. The merged docker-compose.yml will contain db, backend, and frontend services. dev.sh only starts db. What should be the backend command in the merged file — the production CMD from the Dockerfile ("fastapi run"), the dev override CMD ("fastapi dev"), or no command (let Dockerfile CMD apply)?
+
+**Recommended answer:** No command in the compose file — let the Dockerfile's CMD ("fastapi run" — production mode) be the default. If someone runs the backend in a container they get production behavior. dev.sh never starts the backend container anyway, so it doesn't matter for the dev workflow.
+
+**User answer:** _(not recorded)_
+
+**Status:** open
+
+**Notes:** dev.sh only starts 'db' — backend/frontend start natively. The backend CMD in compose only applies if someone runs all containers.
+
+### 8. Should docker-compose.yml contain only the db service, and dev.sh call `docker compose up -d` without any service name?
+
+**Recommended answer:** Yes. Single service (db) in docker-compose.yml, so `docker compose up -d` starts only the database. dev.sh loses the -f flags and service argument. Delete base.yml and dev-override.yml. Keep coolify.yml as deploy reference.
+
+**User answer:** _(not recorded)_
+
+**Status:** open
+
+**Notes:** Backend/frontend service definitions in compose are unused — dev.sh never starts them in containers. Pruning them eliminates maintenance burden and the confusing -f flag dance.
+
+### 9. Create .env.example with all env vars, default values, and inline comments for each section?
+
+**Recommended answer:** Yes. Write .env.example with: PostgreSQL (matching compose defaults), LLM (OpenAI-compatible placeholder), Embeddings (OpenRouter default), optional demo budget settings, optional cross-env copy vars. User will manually review and finalize.
+
+**User answer:** Create the placeholder .env.example and I'll manually edit it for correctness.
+
+**Status:** resolved
+
+**Notes:** File is written to .env.example. Covers all Settings fields from config.py.
+
+### 10. What should docker-compose.yml contain?
+
+**Recommended answer:** Single db service (pgvector/pgvector:pg18 with healthcheck, port, volume, env_file). No backend or frontend services. `docker compose up -d` starts just the database. dev.sh calls `docker compose up -d` without -f flags.
+
+**User answer:** Only the db service, so `docker compose up` starts just the database.
+
+**Status:** resolved
+
+**Notes:** base.yml and dev-override.yml can be deleted. coolify.yml retained as deploy reference.
+
+## Agreed Decisions
+
+- Compose files are not used for building deployable images (CI/CD uses Dockerfiles directly).
+- Merge base.yml + dev-override.yml into one docker-compose.yml with only the db service — backend/frontend services removed since nothing uses them.
+- Delete docker-compose.base.yml and docker-compose.dev-override.yml. Keep coolify.yml as deploy reference.
+- dev.sh becomes: docker compose up -d (no -f flags, no service argument).
+- Add migrate_db() to backend startup lifespan so tables auto-create on fresh clone (~100ms idempotent no-op).
+- Create .env.example with all env vars, sensible defaults, and inline comments.
+- Update AC #8 in the issue to reflect the real dev workflow (clone → cp .env.example .env → ./dev.sh → seed).
+- Tick AC #8 in the issue after changes are made.
+
+## Open Risks
+
+- User still needs to manually run uv run scripts/seed_knowledge_base.py --all after first startup to get corpus data — not automated.
+- The .env.example needs user review for correctness before being committed.
+- If the backend starts before DB is healthy, migrate_db() might fail — need depends_on or retry logic.
