gospec: Instructions file for Codex

AGENTS.md

gospec AGENTS.md is an instructions file for Codex, OpenCode from singchia/gospec. It costs 876 tokens per session, scanned A, original, MIT.

An AGENTS.md instruction system for a Go project, with one main specification file that routes each task to only the relevant guidance. Go is a programming language, and gRPC and HTTP are common ways for software services to communicate.

In plain words
What is it for?
Use it when creating or changing Go services, APIs, tests, data models, deployments, security controls, documentation, or other project work covered by the specification.
Why use it?
It prevents an agent from reading every specification file or ignoring project-wide rules. The routing approach keeps work focused while preserving required checks for coding, testing, APIs, security, and operations.

Instructions file for CodexOpenCode

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

This is singchia/gospec's own configuration. It tells Codex and OpenCode how to work on gospec 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 gospec 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

gospec 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 1mo 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.

How it starts

The opening of the file, as written. The whole thing — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md — go-best-practices

规范入口

唯一入口：spec/spec.md

它包含一张"任务 → 必读文件"路由表。Agent 拿到任务后：

  1. 读 spec/spec.md
  2. 在路由表里找到当前任务
  3. 只读路由表指定的 1-3 个文件
  4. 实施 + 对照文件末尾的"自查清单"

不要顺序读完所有 spec 文件——这违背渐进式披露原则，浪费上下文。

触发条件

当以下场景出现时，Agent 应自动激活此 Skill：

  • 创建或初始化 Go 项目
  • 编写、审查、重构 Go / gRPC / HTTP 代码
  • 设计 API、数据模型、架构
  • 写测试、配置 CI/CD
  • 配置日志 / 指标 / 追踪 / 告警 / SLO
  • 处理认证授权、密钥、依赖漏洞、容器安全、隐私合规
  • 设计部署 / 回滚 / feature flag / Runbook / Postmortem
  • 编写数据库 migration、backfill、数据保留策略
  • 创建 PRD / ADR / HLD
  • 生成 Git commit message

行为约束

  1. 任务开始：先读 spec/spec.md 路由表
  2. 按需加载：只读路由表指定的文件
  3. 强制约束：spec/spec.md 的"核心约束"不可违反，即使没读对应详情文件
  4. 文档创建：使用 docs/templates/ 中的对应模板
  5. 输出语言：默认中文

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.
