# Agent Instructions
## Project Context
Go microservices monorepo using Bazel for builds.
## Build & Test
- Build all: bazel build //...
- Test all: bazel test //...
- Integration tests: docker compose up -d && bazel test //integration/...
- Lint: golangci-lint run ./...
## Code Conventions
- All services follow standard layout in /cmd and /internal
- Use structured logging with slog
- Error wrapping with fmt.Errorf("op: %w", err)
- See @docs/api-style-guide.md for API conventions
## Cross-Repo References
- Shared proto definitions in sourcegraph/proto
- Common Go libraries in sourcegraph/lib
## Security
- Never log sensitive data (tokens, passwords, PII)
- All external inputs must be validated
- Use parameterized queries for database access

# Backend Rules
## Stack
- Python 3.12 with FastAPI
- SQLAlchemy 2.0 with async sessions
- Alembic for migrations
- pytest for testing

- Async endpoints by default
- Pydantic v2 models for request/response schemas
- Repository pattern for database access
## File Structure
- app/api/routes/ — API endpoints
- app/models/ — SQLAlchemy models
- app/schemas/ — Pydantic schemas
- app/services/ — Business logic
