EchoBot: Instructions file for Codex

AGENTS.md

EchoBot AGENTS.md is an instructions file for Codex, OpenCode from KdaiP/EchoBot. It costs 406 tokens per session, scanned A, original, MIT.

Python coding guidelines for an AI agent, written partly in Chinese. They emphasize readable code, clear responsibilities, standard-library use, and safe handling of asynchronous work.

In plain words
What is it for?
Writing or reviewing Python 3.11+ functions and modules, choosing file and JSON handling approaches, sharing core logic, and moving blocking work to background threads when needed.
Why use it?
They reduce confusing code and prevent slow file, network, or CPU-heavy tasks from blocking other asynchronous work.

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

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

EchoBot 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.

What it actually says

AGENTS.md

本代码库以简洁与可读性优先。 请编写 Python 初学者也能看懂、维护和扩展的代码。

原则 (Principles)

  1. 清晰至上 (Clarity first)

    • 编写简单、清晰、易于理解的代码。
    • 避免过早优化和不必要的抽象。
    • 遵循《Python 之禅》(The Zen of Python) 。
    • 目标版本为 Python 3.11+;避免使用已弃用的写法。
  2. 单一职责 (Single responsibility)

    • 每个函数/类/模块都应当只把 一件事 做好。
  3. 关注性能 (Performance-aware)

    • 在关键路径上对性能保持敏感。
    • 在异步代码中,绝不要因为磁盘/网络 I/O 或 CPU 密集型任务而阻塞事件循环。

风格与规范 (Style & conventions)

  • 使用描述性的名称;避免使用晦涩难懂的单行代码。
  • 优先使用 pathlib 而非 os.path。
  • 除非引入依赖项确实物超所值,否则优先使用标准库。
  • 使用 json.dump 或 json.dumps 时,必须设置 ensure_ascii=False,以确保输出内容支持中文原样显示,提高可读性。
  • 所有入口复用同一个 Core,而不是各做一套业务逻辑。

异步 (适用时)

  • 不要在 async def 中运行阻塞式 I/O 或 CPU 密集型任务。
  • 使用 asyncio.to_thread(...)(必要时使用 executor)将阻塞任务转移出去。
  • 在可能的情况下,保持异步 API 从端到端的一致性。
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.
