# 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

.rules

markdown

# Project Rules

## Stack
- TypeScript 5.x with strict mode
- React 19 with Server Components
- Tailwind CSS v4
- Drizzle ORM with PostgreSQL

## Code Style
- Prefer named exports over default exports
- Use "use client" directive only when interactivity is required
- Colocate tests in __tests__ directories next to source files
- Use Zod for all runtime validation

## Architecture
- App Router with nested layouts in app/
- Server actions in app/actions/
- Database schema in db/schema.ts
- Shared utilities in lib/

## Commands
- Dev server: pnpm dev
- Type check: pnpm typecheck
- Test: pnpm test
- Lint: pnpm lint

KEY DIFFERENCES

1. Subdirectory scoping

Amp: Supported. Zed: Not supported.

2. IDE integration

Amp: CLI. Zed: Editor.

WHICH SHOULD I USE?

Recommendation

Choose based on your IDE/CLI preference. If you use Amp, configure AGENTS.md. If you use Zed, configure .rules. Many projects include config files for multiple tools so each team member can use their preferred editor.
