Phoenix Backend Development
Phoenix is an AI observability platform. The backend is Python: FastAPI serving a REST API and Strawberry GraphQL API over an async SQLAlchemy ORM (PostgreSQL + SQLite).
Development Guide Index
Read DEVELOPMENT.md (env setup, uv, tests, debugpy, pre-commit, REST API conventions) and CONTRIBUTING.md (PR format, conventional commits, code review expectations) if you have not already.
Everyday Commands
make dev-backend # backend only, no frontend build needed
uv run pytest path/to/test -n auto # run specific tests in parallel
make test-python # full test suite
make graphql # regenerate schema after GQL changes
make format # format all code
make typecheck-python # mypy + pyright

phoenix-cli
Debug LLM applications using the Phoenix CLI. Fetch traces, analyze errors, structure trace review with open coding and axial coding, inspect datasets, review experiments, query annotation configs, and use the GraphQL API. Use whenever the user is analyzing traces or spans, investigating LLM/agent failures, deciding what to do after instrumenting an app, building failure taxonomies, choosing what evals to write, or asking "what's going wrong", "what kinds of mistakes", or "where do I focus" — even without naming a technique.
496phoenix-tracing
OpenInference semantic conventions and instrumentation for Phoenix AI observability. Use when implementing LLM tracing, creating custom spans, or deploying to production.

Build and run evaluators for AI/LLM applications using Phoenix.
433agent-browser
Browser automation CLI for AI agents. Use when the user needs to interact with websites, including navigating pages, filling forms, clicking buttons, taking screenshots, extracting data, testing web apps, or automating any browser task. Triggers include requests to "open a website", "fill out a form", "click a button", "take a screenshot", "scrape data from a page", "test this web app", "login to a site", "automate browser actions", or any task requiring programmatic web interaction.
