+# AI Knowledge Base - Agent Instructions
+
+## Project Overview
+
+AI-powered knowledge base seeded from Confluence, with Slack bot interface, RAG pipeline, and Graphiti/Neo4j knowledge graph.
+
+- **GCP Project**: `ai-knowledge-base-42`, region `us-central1`
+- **Architecture doc**: `docs/ARCHITECTURE.md` (read this first)
+- **ADRs**: `docs/adr/` (design decisions and rationale)
+
+## Git Workflow
+
+- **NEVER push directly to `main`** — always create a feature branch and open a PR
+- Branch naming: `feature/`, `fix/`, `chore/`, `refactor/` prefixes
+- CI/CD runs on every push: unit tests, build, deploy staging, e2e tests, deploy production
+- PRs require passing CI before merge
+
+```bash
+git checkout -b feature/my-change
+# ... make changes ...
+git push -u origin feature/my-change
+gh pr create --title "Add my change" --body "..."
+```
+
+## Tech Stack
+
+| Component | Technology | Notes |
+|-----------|------------|-------|
+| Knowledge Graph | Neo4j 5.26 + Graphiti-core | Source of truth for all knowledge data |
+| Metadata DB | SQLite + SQLAlchemy 2.0 async (NullPool) | Page sync, checkpoints, feedback |
+| LLM | Gemini 2.5 Flash (Vertex AI) | Entity extraction, answer generation |
+| Embeddings | Vertex AI text-embedding-005 | 768-dim vectors |
+| Bot | Slack Bolt (HTTP mode) | Primary user interface |
+| Infra | Cloud Run (bot, jobs) + GCE (Neo4j) | Terraform in `deploy/terraform/` |
+
+## Key Conventions
+
+### Code
+
+- Python 3.11, async/await for I/O
+- Type hints on all function signatures
+- `pydantic-settings` for config — all settings via environment variables, no hardcoded values
+- SQLite uses NullPool (connections close immediately) and WAL mode
+- Checkpoint writes use raw `aiosqlite` (bypass SQLAlchemy to avoid lock contention)
+- Tests in `tests/` — unit, integration, e2e subdirectories
+
+### Pipeline
+
+- CLI: `python -m knowledge_base.cli pipeline`
+- Steps: download (Confluence) -> parse (chunks) -> index (Graphiti)
+- `ConfluenceDownloader(index_to_graphiti=False)` in pipeline — Step 3 handles indexing
+- Checkpoints persisted to GCS FUSE after every batch (see ADR-0010)
+- Resume is automatic — already-indexed chunks are skipped on restart
+
+### Docker Images
+
+Two separate images — must rebuild both when code changes:
+- `Dockerfile.jobs` -> `jobs:latest` (pipeline, background tasks)
+- `Dockerfile.slack` -> `slack-bot:latest` (Slack bot service)
+
+### Environments
+
+- **Staging**: Neo4j at `bolt+s://neo4j.staging.keboola.dev:443`
+- **Production**: Neo4j at `bolt://10.0.0.27:7687` (internal VPC)
+- Always test on staging first before production
+- Use `--dry-run` when available
+
+### Terraform
+
+- Located in `deploy/terraform/`
+- `google-beta` provider required for GCS FUSE volumes
+- Run `terraform plan` before `terraform apply`
+- State locks can go stale — use `terraform force-unlock` if needed
+
+## Testing
+
+```bash
+# Unit + integration tests
+python -m pytest tests/ -v
+
+# E2E tests (needs staging secrets)
+./scripts/setup-e2e-env.sh
+set -a && source .env.e2e && set +a
+python -m pytest tests/e2e/ -v
+```
+
+## Common Operations
+
+```bash
+# Check pipeline job
+gcloud run jobs executions list --job=sync-pipeline --region=us-central1 --project=ai-knowledge-base-42 --limit=5
+
+# Check staging sync
+gcloud run jobs executions list --job=confluence-sync-staging --region=us-central1 --project=ai-knowledge-base-42 --limit=5
+
+# Build and push jobs image
+printf 'steps:\n  - name: "gcr.io/cloud-builders/docker"\n    args: ["build", "-t", "us-central1-docker.pkg.dev/ai-knowledge-base-42/knowledge-base/jobs:latest", "-f", "deploy/docker/Dockerfile.jobs", "."]\nimages:\n  - "us-central1-docker.pkg.dev/ai-knowledge-base-42/knowledge-base/jobs:latest"\n' | gcloud builds submit --config /dev/stdin --project=ai-knowledge-base-42 .
+
+# Build and push slack-bot image
+printf 'steps:\n  - name: "gcr.io/cloud-builders/docker"\n    args: ["build", "-t", "us-central1-docker.pkg.dev/ai-knowledge-base-42/knowledge-base/slack-bot:latest", "-f", "deploy/docker/Dockerfile.slack", "."]\nimages:\n  - "us-central1-docker.pkg.dev/ai-knowledge-base-42/knowledge-base/slack-bot:latest"\n' | gcloud builds submit --config /dev/stdin --project=ai-knowledge-base-42 .
