Repository Guidelines

Scope & Inheritance

• This is the canonical monorepo guide for shared contribution policy.
• Module-level AGENTS.md files should keep only module-specific guidance and reference this file for shared rules.

Project Structure & Module Organization

This repository is a multi-module Opik codebase. Main areas:

• apps/opik-backend: Java backend (source in src/main/java, tests in src/test/java).
• apps/opik-frontend: React/TypeScript frontend (src and related assets/config).
• apps/opik-documentation: documentation website and generated API docs.
• sdks/python, sdks/typescript, sdks/opik_optimizer: SDK packages and examples.
• deployment, scripts, extensions: infra, tooling, and integration extension points.
• tests_end_to_end, tests_load: cross-stack and performance test suites.

Build, Test, and Development Commands

• ./opik.sh — run default local stack via Docker.
• ./opik.sh --build — rebuild images and run the full stack.
• ./opik.sh --verify — run stack health checks.
• ./opik.sh --stop — stop local services.
• scripts/dev-runner.sh — fast local process mode (BE + FE).
• scripts/dev-runner.sh --be-only-restart — backend-focused local development.
• scripts/dev-runner.sh --build-be / --build-fe — build one side only.
• scripts/dev-runner.sh --lint-be — Java lint/format checks.
• scripts/dev-runner.sh --lint-fe — frontend lint/type checks via npm.
• cd apps/opik-frontend && npm run lint && npm run test — run ESLint + Vitest.
• cd apps/opik-frontend && npm run build — production frontend build.
• cd apps/opik-backend && mvn test — backend unit/integration tests.
• cd apps/opik-backend && mvn spotless:apply — apply Java formatting.
• cd sdks/python && pip install -r tests/test_requirements.txt && pip install -r tests/unit/test_requirements.txt && pytest tests/unit tests/e2e — Python SDK test suites.
• make precommit — run pre-commit hooks on changed files (vs origin/main) from the root .pre-commit-config.yaml across all modules (do not duplicate per-module command lines in multiple places).
• cd sdks/typescript && npm run lint && npm run test && npm run build — TS SDK checks.
• cd tests_end_to_end/e2e && npx playwright test — cross-stack Playwright E2E suite.

Coding Style & Naming Conventions

• Use existing module formatters/conventions and keep edits scoped; avoid blanket reformatting.
• For detailed coding rules, defer to module-level AGENTS.md files and skill docs (for example .agents/skills/python-sdk/good-code.md) instead of duplicating style guidance here.

Testing Guidelines

• Frameworks: Vitest (frontend + TS SDK), Playwright (frontend E2E), Maven/JUnit (backend), pytest (Python SDK).
• Naming conventions:
  • Java: *Test.java in apps/opik-backend/src/test/java.
  • Python: test_*.py grouped under tests/unit, tests/integration, tests/e2e.
  • TypeScript/JS: *.test.ts under tests.
• Cover changed behavior with unit tests first; add integration/E2E when cross-layer behavior changes.
• For SDK integration tests requiring external services, document any required keys in the PR.
• For end-to-end execution across backend/frontend, use:
  • ./opik.sh or scripts/dev-runner.sh to start local services
  • tests_end_to_end/e2e/README.md for suite-specific command and setup

Agent Contribution Workflow

• This repository is a monorepo; submodule AGENTS.md files inherit this workflow by default.
• Read CONTRIBUTING.md and .github/pull_request_template.md before editing or opening a PR.
• Link tracked work in PRs with Fixes #<id> or Resolves #<id>.
• Use GitHub CLI for PR flow and prefer draft PRs first (gh pr create --draft).
• Prefer worktrees for parallel workstreams when touching multiple components.
• Run relevant unit tests and formatters for the touched area before requesting review.

Commit & Pull Request Guidelines

• PR title and first commit should use semantic style with ticket prefix: [OPIK-1234] [COMPONENT] feat|fix|refactor|docs: short summary.
• Follow existing component prefixes ([FE], [SDK], [DOCS], [NA], [INFRA], etc.).
• PR descriptions should include: change summary, test coverage run, and linked issue references (Resolves #...).
• Follow pull_request_template.md sections: Details, checklist, Issues, Testing, Documentation.
• Include screenshots or short recordings for user-visible UI changes when possible.

Ignored Surfaces

• .github/instructions/ contains GitHub Copilot-specific instruction files. Other agents should ignore this directory and use .agents/ as the canonical source.
• .github/copilot-instructions.md is GitHub Copilot code review guidance only.

Security & Configuration Tips

• Keep secrets and API keys out of source control; use local .env or shell variables.
• For local self-hosted testing, ensure dependencies are configured (MySQL, ClickHouse, Redis) before running backend tests.
• Prefer opik configure --use_local when running SDK examples against your local deployment.

Generated Files

• apps/opik-backend/src/main/resources/model_prices_and_context_window.json and apps/opik-frontend/src/data/model_prices_and_context_window.json are generated artifacts.
• Do not edit these files directly; updates should come from the repository updater automation.
