Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md; mentions subagents; mentions Claude Code.

This is zhinjs/zhin's own configuration. It tells Claude Code how to work on zhin 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 zhin configures →

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is "extends": "../../tsconfig.base.json",.

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

zhin CLAUDE.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.

Project Overview

Zhin.js is a TypeScript chatbot framework — AI-driven, plugin-based, hot-reload, multi-platform. ESM-only ("type": "module"), targets Node.js >=22.19.0.

Commands

pnpm build              # Full build (Turborepo: basic/ → packages/ → plugins/)
pnpm test               # Run all Vitest tests
pnpm test:watch         # Watch mode
pnpm test:coverage      # Coverage report
pnpm lint               # ESLint (.ts,.tsx)
pnpm type-check         # tsc --noEmit -p tsconfig.typecheck.json
pnpm dev                # Start minimal-bot (examples/minimal-bot); use pnpm dev:test for test-bot
pnpm clean              # Clean all lib/ dist/ directories
pnpm eval:chat --workspace <dir> --judge <alias/model>  # Real-model chat quality eval (local, not CI)

# Bootstrap (first-time or after clean)
pnpm prepare:logger     # Build @zhin.js/logger + install CLI deps
pnpm prepare:cli        # Build scaffold-wizard + CLI + reinstall

# Single package
pnpm --filter @zhin.js/core build
pnpm --filter @zhin.js/core test

# Run a single test file
pnpm vitest run packages/im/core/tests/plugin.test.ts

Custom lint checks:

  • pnpm check:harness-paths — 检测插件是否绕过 Adapter.sendMessage 直调 bot.$sendMessage
  • pnpm check:no-koa — 检测插件是否直接 import koa(应使用 RouterContext)
  • pnpm check:prod — 检查生产环境配置(无 console.log/debugger/TODO/FIXME)
  • pnpm check:plugin — 检查插件是否符合标准规范(入口文件、测试、README)
  • pnpm check:no-removed-plugin-api — 检测是否重新调用已从 public surface 删除的 Plugin lookup API
  • pnpm check:plugin-agent-publish — 带 agent/ 的插件发布清单(files、prepublishOnly)
  • pnpm check:all — 运行所有 harness 检查(含 type-check / lint / test)

Architecture

Monorepo managed with pnpm 9.0.2 workspaces + Turborepo (turbo.json). Versioning via Changesets.

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.
