rez-next AGENTS.md

rez-next AGENTS.md is an instructions file for Codex, OpenCode from loonghao/rez-next. It costs 1,935 tokens per session, scanned A, original, Apache-2.0.

Project instructions for rez-next, a Rust rewrite of the Rez package manager with Python bindings. A package manager installs and manages software dependencies and environments.

In plain words
What is it for?
Use them when developing, building, testing, or documenting rez-next and its Rust or Python interfaces.
Why use it?
They help an agent understand the project’s supported workflows, build system, command-line interface, and Python API boundaries.

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

rez-next AGENTS.md scanned grade A with 0 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 3d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Project Overview

rez-next is a high-performance Rust rewrite of the Rez package manager with Python bindings. It supports common Rez workflows without mirroring Rez's internal implementation modules.

Key facts for agents:

  • Language: Rust 2024 edition (MSRV 1.95) + Python 3.9+ bindings (PyO3 abi3)
  • Build system: Cargo workspace (20 crates) + Maturin for Python
  • Current version: 0.3.6 (see CHANGELOG.md)
  • License: Apache 2.0
  • Python API: curated top-level interfaces backed by native PyO3 modules
  • CLI: 28 subcommands (config, context, view, env, release, test, build, search, bind, depends, solve, cp, mv, rm, status, diff, pkg-help, plugins, pkg-cache, suites, bundle, pip, complete, forward, gui, parse-version, self-test, self-update)
  • Status: Common workflows work with import rez_next as rez; internal namespaces such as rez.utils are intentionally not mirrored.

Quick Start

# Drop-in replacement for most use cases
import rez_next as rez
from rez_next.packages_ import iter_packages, get_latest_package
from rez_next.resolved_context import ResolvedContext

# Supported top-level API
ctx = rez.resolve_packages(["python-3.9", "maya-2024"])
pkg = rez.get_latest_package("python")

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.
