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

next-js-server-actions 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 4d 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

  • 将预期错误建模为返回值:避免在服务器操作中对预期错误使用 try/catch。使用 useActionState 管理这些错误并将其返回给客户端。
  • 对意外错误使用错误边界:使用 error.tsx 和 global-error.tsx 文件实现错误边界,以处理意外错误并提供回退 UI。
  • 将 useActionState 与 react-hook-form 一起用于表单验证。
  • services/ 目录中的代码始终抛出用户友好的错误,tanStackQuery 可以捕获并向用户显示。
  • 对所有服务器操作使用 next-safe-action:
    • 实现具有适当验证的类型安全服务器操作。
    • 利用 next-safe-action 的 action 函数创建操作。
    • 使用 Zod 定义输入模式以进行强大的类型检查和验证。
    • 优雅地处理错误并返回适当的响应。
    • 使用 import type { ActionResponse } from '@/types/actions'
    • 确保所有服务器操作返回 ActionResponse 类型
    • 使用 ActionResponse 实现一致的错误处理和成功响应

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.
