homebrew-starcat-cli: Instructions file for Codex

AGENTS.md

homebrew-starcat-cli AGENTS.md is an instructions file for Codex, OpenCode from starcat-app/homebrew-starcat-cli. It costs 736 tokens per session, scanned A, original, MIT.

A set of repository instructions for a Homebrew tap, which is a source of installation formulas for command-line software. It covers distributing the Starcat CLI and its MCP bridge on macOS and Linux.

In plain words
What is it for?
Maintaining the Homebrew formula, checking platform archives and SHA-256 hashes, and running Homebrew audits and installation tests.
Why use it?
It keeps formula changes in the correct repository and helps verify package style, checksums, installation, and release archives without changing the CLI source project.

Instructions file for CodexOpenCode

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

This is starcat-app/homebrew-starcat-cli's own configuration. It tells Codex and OpenCode how to work on homebrew-starcat-cli 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 homebrew-starcat-cli 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 A, and why

homebrew-starcat-cli 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 yesterday.

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.

What it actually says

AGENTS.md — Starcat CLI Homebrew Tap

本文档是本仓库 AI 协作规则的唯一维护源。

独立仓库边界

  • 本目录是 starcat-app/homebrew-starcat-cli 独立 Git 仓库,不属于 starcat-cli 或 Starcat App 仓库。
  • 修改前必须确认当前分支与工作区状态;未经 dong4j 明确要求,不得切换分支、提交或处理其他仓库。
  • 本仓只负责 Homebrew Formula 分发;CLI 源码、跨平台构建和 GitHub Release 由 starcat-app/starcat-cli 维护。

用途与技术栈

本仓库是 Starcat CLI 与 MCP bridge 的官方 Homebrew tap,安装命令与 Formula 均名为 starcat。Formula 使用 Homebrew Ruby DSL,按 macOS/Linux 与 arm64/amd64 选择不可变的 GitHub Release 压缩包,并用 SHA-256 校验。

  • Homebrew Formula DSL / Ruby
  • GitHub Actions macOS runner
  • GitHub Release 跨平台归档
  • SHA-256 完整性校验

关键目录

  • Formula/starcat.rb:版本、各平台归档 URL、SHA-256、安装和版本测试。
  • .github/workflows/audit.yml:Formula 存在时执行 style 与 strict audit。
  • README.md / README-ZH.md:安装、升级和自动维护边界。
  • CONTRIBUTING.md / SECURITY.md:自动生成与校验和要求。

开发与验证

brew style Formula/starcat.rb
brew tap starcat-app/starcat-cli "https://github.com/starcat-app/homebrew-starcat-cli.git"
brew audit --strict --formula starcat-app/starcat-cli/starcat
brew test starcat-app/starcat-cli/starcat
git diff --check

brew audit 必须使用已安装的 tap 名称,不能把仓库内相对路径直接作为目标。

项目特有约束

  • 稳定版 Formula/starcat.rbstarcat-cli 的 Release workflow 自动生成并提交。 正常维护不得手工改版本、URL 或校验和;只有自动化不可用且 dong4j 明确授权时才能修复。
  • Formula 必须引用不可变的 GitHub Release 归档;每个平台的 sha256 必须来自 同一次 CLI 构建生成的 checksums.txt,禁止猜测、复用或跨版本混用。
  • 必须完整保留 macOS arm64/amd64 与 Linux arm64/amd64 映射,架构条件和文件名 必须与 starcat-cli 发布资产一致。
  • Homebrew 管理 Cellar 内的二进制;不得让 Formula 调用 starcat update 覆盖安装文件。
  • CLI 行为或 MCP contract 的变更应在 starcat-cli 仓库完成,不得在 tap 中复制实现。

发布禁令

未经 dong4j 在当前任务中明确授权,禁止创建或推送 tag、执行 git push、发布 GitHub Release、上传归档、手工更新远端 Formula、触发发布自动化或执行任何对外分发操作。

Changes

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.
