What it does
Phoenix Server is an agent skill from Arize-ai/phoenix. Backend development guide for the Phoenix AI observability platform (Strawberry GraphQL, SQLAlchemy async, FastAPI). Use this skill when writing or modifying Python server code in the phoenix repo — adding mutations, types, migrations, or tests. Trigger on any backend task touching src/phoenix/server/, src/phoenix/db/, or tests/unit/server/.
Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `references/database-patterns.md`, `references/graphql-patterns.md` and `references/llm-trace-tests.md`).
It sits in Backend & APIs, covering LLM observability, Backend development and GraphQL. It works with GraphQL, FastAPI, Python and SQLAlchemy. The repository describes itself as: AI Observability & Evaluation.
When your agent uses it
- Modifying Python server code in the phoenix repo — adding mutations
- Any backend task touching src/phoenix/server/
- Src/phoenix/db/
- Tests/unit/server/
Example prompts
- “/phoenix-server”
Requirements
- Python 3
What it can do on your machine
Read from SKILL.md and the folder at commit 3383f07. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
makeuv
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use uv, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Phoenix Server loads about 1.6k tokens when it runs, and up to ~10k if it reads all its reference files. Until then it costs about 90 tokens; SKILL.md has 654 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 654 words (~1,649 tokens).
“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).”
