agentic-perf: Instructions file for Codex

AGENTS.md

agentic-perf AGENTS.md is an instructions file for Codex, OpenCode from atheurer/agentic-perf. It costs 3,702 tokens per session, scanned B, original, Apache-2.0.

Project instructions for agentic-perf, a system that uses specialized AI workers to run performance tests and return structured results.

In plain words
What is it for?
Use them when changing or operating the agentic-perf codebase, especially its Python services, AI agents, tool servers, benchmark workflow, and coordinator.
Why use it?
They give an agent the project layout, technology choices, service details, and rules it needs to work in the repository correctly.

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

This is atheurer/agentic-perf's own configuration. It tells Codex and OpenCode how to work on agentic-perf 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 agentic-perf 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 B, and why

agentic-perf AGENTS.md scanned grade B with 2 findings 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 today.

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.

agentic-perf — AI Agent Guidelines

Project Overview

Multi-agent system for autonomous performance testing. Engineers submit natural-language requests; specialized AI agents triage, acquire hardware, install tooling, execute benchmarks, and deliver structured analysis.

Stack: Python 3.12+, FastAPI, asyncio, MCP, Pydantic, httpx. License: Apache 2.0.

Contributor Agent Skills

Repository-local contributor skills live under .agents/skills/ and are separate from runtime capabilities under skills/. Use the PR-cycle skill for the existing-PR review and landing workflow, and the orchestration-development skill for changes to agent context, prompts, handoffs, dispatch, and ticket state. These skills complement this file and the project documentation; follow this file for the repository's current development rules.

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.
