NoteMeld: Instructions file for Codex

AGENTS.md

NoteMeld AGENTS.md is an instructions file for Codex, OpenCode from Hehejie1/NoteMeld. It costs 1,067 tokens per session, scanned A, original, MIT.

Repository instructions for NoteMeld that require agents to understand the current architecture, product rules, data model, APIs, known problems, and change process before editing code.

In plain words
What is it for?
Use them for new features, bug fixes, refactors, interface or database changes, and related testing or documentation work in NoteMeld.
Why use it?
They reduce the risk of guessing about existing behavior, breaking interfaces, or changing data and business rules incorrectly.

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

This is Hehejie1/NoteMeld's own configuration. It tells Codex and OpenCode how to work on NoteMeld 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 NoteMeld 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

NoteMeld 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 6d 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.

AGENTS.md

本文件是 NoteMeld 项目中所有 AI Agent 和开发者的硬规则。任何新需求、方案、代码修改、Bug 修复、重构、接口变更、数据模型变更开始前,必须遵守。

必读文档

开始任何新需求前,必须先阅读:

  • docs/system/current-architecture.md
  • docs/system/product-rules.md
  • docs/system/data-model.md
  • docs/system/api-inventory.md
  • docs/system/known-pitfalls.md

只读 README、只看用户描述、只根据记忆或猜测写方案,均不合格。

必须搜索现状

动手前必须搜索相关代码和测试:

  • 相关前端页面、组件、服务调用。
  • 相关后端 router、service、model、utils。
  • 相关 SQLite 表、文件结构、状态文件、sidecar 文件。
  • 相关契约测试、回归测试、打包脚本和文档测试。

如果找不到现状,必须继续查或向用户提问,不能猜。

禁止事项

  • 不能直接生成孤立 PRD。
  • 不能在不了解现状的情况下写实现方案。
  • 不能凭猜测改数据库字段、接口语义或核心业务规则。
  • 不能绕过 docs/system/change-spec-template.md
  • 不能只做理想化重构方案,必须基于当前真实系统。
  • 不能为了局部改动删除已有能力。
  • 不能做无关重构。
  • 不能删除用户未明确要求删除的能力。
  • 不能回滚用户或其他 Agent 的改动,除非用户明确要求。
  • 不能暴露 Provider API Key、Cookie、token、用户本地路径或敏感 payload。
  • 不能破坏源码启动、CLI、桌面、MCP、迁移、Wiki、上传、打包发布任一既有入口。

Change Spec 规则

所有新需求必须先产出增量 Change Spec。模板见:

docs/system/change-spec-template.md

Change Spec 必须回答:

  • 当前系统现状是什么。
  • 本次目标是什么。
  • 明确不做什么。
  • 和产品规则、数据模型、API、历史坑点是否冲突。
  • 影响哪些模块、接口、数据、UI、测试和文档。
  • 最小可行改动是什么。
  • 如何测试和验收。
  • 风险和回滚是什么。

用户明确要求“直接修 Bug”时,也必须至少在回复或提交说明中覆盖根因、影响范围和回归测试。

Bug 修复规则

Bug 修复必须说明:

  • 根因。
  • 影响范围。
  • 复现方式或证据。
  • 修复点。
  • 回归测试。
  • 未覆盖风险。

不能只说“已修复”。没有验证证据,不得声称通过。

文档同步规则

修改以下内容时,必须同步更新 docs/system/

  • 系统架构、运行入口、部署方式。
  • 产品硬规则或 UX 行为。
  • SQLite 表、字段、文件结构、状态流转、缓存和统计口径。
  • API 路径、请求参数、返回结构、错误语义或调用方。
  • MCP 工具。
  • Wiki rebuild、任务状态、桌面 sidecar、迁移、上传、打包发布等核心链路。
  • 新发现的坑点和回归防线。

最小改动规则

  • 优先复用现有模块、helper、router、service、测试模式。
  • 只做满足需求的最小可行改动。
  • 保持已有数据兼容。
  • 保持已有 API 调用方兼容,必要时提供兼容层。
  • 保持旧数据、历史状态和已有文件结构可读取。
  • 涉及并发、取消、超时、文件写入时,必须考虑 race condition 和脏状态。

新需求前 Agent 必答问题

任何新需求开始前,Agent 必须回答:

  • 这个需求影响哪些已有模块?
  • 当前系统是否已有类似能力?
  • 是否和产品规则冲突?
  • 是否和数据模型字段语义冲突?
  • 是否会重新引入 known-pitfalls 中的问题?
  • 是否影响本地数据或线上服务?
  • 最小可行改动是什么?
  • 需要补哪些测试防止回归?

如果答不清楚,必须继续查代码、查文档、查测试,或者向用户提问,不能猜。

推荐验证命令

按改动范围选择验证:

python3 -m compileall backend/app
pytest backend/tests
cd frontend && pnpm test:contracts
cd frontend && pnpm build
scripts/run_core_regression.sh

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.
