openlark: Instructions file for Codex

AGENTS.md

openlark AGENTS.md is an instructions file for Codex, OpenCode from foxzool/openlark. It costs 2,688 tokens per session, scanned A, original, Apache-2.0.

A contributor guide for OpenLark, a Rust software development kit for Feishu/Lark, an enterprise messaging and collaboration platform. It maps the repository’s business modules and key source locations.

In plain words
What is it for?
Use it when adding Feishu/Lark APIs, working on authentication, HTTP requests, WebSockets, errors, documents, human resources, workflows, or meetings.
Why use it?
It helps an agent find the right module and shared infrastructure instead of searching the whole repository or placing an API in the wrong area.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: reads .claude/ paths.

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

openlark 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 5d 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.

WHERE TO LOOK

Task Location Notes
添加新 API crates/openlark-*/src/**/v*/ 按业务模块和版本组织
错误处理 crates/openlark-core/src/error/ CoreError 企业级错误系统
HTTP 客户端 crates/openlark-core/src/http.rs 共享 reqwest 配置
模型定义 */models.rs 或 */models/ Serde 序列化结构体
Feature flags Cargo.toml [features] 50+ 功能标志

CONVENTIONS

模块组织

  • 业务领域驱动: 按功能(HR/Docs/IM)而非技术层次组织
  • 版本化 API: v1/, v2/ 子目录管理不同 API 版本
  • 模型分离: 请求/响应模型放在 models/ 或 models.rs

代码风格

  • 中文优先: 文档和注释使用中文,面向中国开发者
  • Builder 模式: API 请求使用流畅的构建器模式
  • Feature 条件编译: #[cfg(feature = "...")] 控制模块编译
  • 错误处理: 统一使用 CoreError,支持链式错误上下文

API 实现模式

// 1. 定义请求结构体(Builder 模式)
pub struct CreateXxxRequest { config: Config, ... }
impl CreateXxxRequest {
    pub fn new(config: Config) -> Self { ... }
    pub fn field(mut self, value: T) -> Self { ... }
    pub async fn execute(self) -> Result<XxxResponse> { ... }
}

// 2. 模型使用 Serde
#[derive(Debug, Serialize, Deserialize)]
pub struct XxxResponse { ... }

// 3. 验证使用宏
validate_required!(self.field, "字段不能为空");

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.
