Skill for Claude CodeCodex

Written for Claude Code: user-invocable in frontmatter. Also seen: installed under .agents/ (shared by several agents).

This is Arize-ai/phoenix's own configuration. It tells Claude Code and Codex how to work on phoenix itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything phoenix configures →

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /Users/.../.agent-browser/tmp/screenshots/screenshot-<timestamp>.png.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

phoenix-pr-screenshot scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

- Wait for the server to be ready: `sleep 10 && curl -s -o /dev/null -w "%{http_code}" http://localhost:6007/playground` should return 200

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
