test-proxy-recorder: Instructions file for Codex

AGENTS.md

test-proxy-recorder AGENTS.md is an instructions file for Codex, OpenCode from asmyshlyaev177/test-proxy-recorder. It costs 3,289 tokens per session, scanned C, original, MIT.

Repository guidance for a pnpm monorepo that records and replays HTTP and WebSocket traffic for repeatable end-to-end tests. A monorepo stores several related packages in one repository.

In plain words
What is it for?
Use it when changing the proxy, HTTP or WebSocket recording, replay sessions, redaction, CLI, Playwright integration, or server-rendering helpers for Next.js and TanStack Start.
Why use it?
Recording real network exchanges lets tests replay the same responses instead of depending on changing external services, making failures easier to reproduce.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is asmyshlyaev177/test-proxy-recorder's own configuration. It tells Codex and OpenCode how to work on test-proxy-recorder 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 test-proxy-recorder configures →

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 C, and why

test-proxy-recorder AGENTS.md scanned grade C 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 22d 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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

⚠ **Expressive-code output is cached in `.astro/`.** A change to the EC config or to either plugin leaves already-rendered pages untouched, so a partial rebuild reads as "the fix didn't work". `rm -rf .astro node_modules

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.
