MoYuCode AGENTS.md is an instructions file for Codex, OpenCode from AIDotNet/MoYuCode. It costs 1,224 tokens per session, scanned A, original, MIT.

Repository instructions for MoYuCode, an application with an ASP.NET Core Web API backend and a Vite, React, and TypeScript web interface. They describe its folders, build commands, coding conventions, and testing practices.

In plain words
What is it for?
Use them when changing the backend or frontend, installing dependencies, running the development servers, building the application, or checking code quality.
Why use it?
They help contributors find the right part of the project and use the expected commands for compiling, running, linting, and building it. They also document project-specific style and organization rules.

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

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

MoYuCode 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 2mo 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.

Repository Guidelines

Project Structure & Module Organization

  • src/MoYuCode/: ASP.NET Core Web API (net10.0) with EF Core (SQLite).
    • Api/: minimal API endpoint mappings (see ApiEndpoints.cs).
    • Controllers/: REST controllers.
    • Data/: MyYuCodeDbContext and entity models.
    • Contracts/ and Services/: shared DTOs and business logic.
  • web/: Vite + React + TypeScript UI.
    • web/src/: app code; the @/ alias maps here.
    • web/public/: static assets; build output in web/dist/.
  • MoYuCode.slnx: solution referencing the backend project.

Build, Test, and Development Commands

Backend:

  • dotnet build src/MoYuCode/MoYuCode.csproj — compile the API.
  • dotnet run --project src/MoYuCode/MoYuCode.csproj --launch-profile http — run on http://localhost:9110 (use --launch-profile https for https://localhost:9111).

Frontend (from web/):

  • npm ci — install dependencies (uses package-lock.json).
  • npm run dev — start Vite dev server.
  • npm run build — typecheck and build to web/dist/.
  • npm run lint — run ESLint.

Coding Style & Naming Conventions

  • C#: 4-space indentation; nullable reference types are enabled—avoid introducing new warnings. Use PascalCase for types/methods and camelCase for locals/parameters.
  • Frontend: components in PascalCase.tsx, hooks in useX.ts. Prefer importing via @/… when applicable.
  • Formatting: no repo-wide formatter is enforced; keep diffs focused and run lint before opening a PR.

Testing Guidelines

  • Automated tests are not set up yet (no *.Tests.csproj or JS test runner). If adding tests, place them under tests/ and ensure dotnet test runs.

Commit & Pull Request Guidelines

  • Git history is empty; use a consistent convention going forward (e.g., Conventional Commits: feat: …, fix: …, chore: …).
  • PRs should include a short summary, testing notes (commands run), and screenshots for UI changes. Avoid committing build artifacts (bin/, obj/, web/dist/, web/node_modules/).

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.
