What it does

Validate Then Transact is an agent skill from yyw-code/MallBase. MallBase ThinkPHP 写操作与事务规则；实现或修改 create、update、delete、状态流转、多表写入、余额库存变更、行锁、条件更新或并发一致性校验时使用。

Its SKILL.md is about 310 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with PHP. The repository describes itself as: MallBase 是一个基于 PHP 的商城型业务基础框架，围绕 用户、商品、订单、权限 四个最核心的商业模块，提供一套清晰、稳定、可扩展的业务结构基线。 它不是一个功能齐全的电商系统，也不是通用 Web 框架，而是一个专注于“商城核心模型”的业务底座，用于快速构建和演进各类商业应用。 The licence is MIT.

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. 在事务外完成参数格式、权限、静态业务规则和不依赖锁的存在性检查。
  2. 只在需要原子多表写入或并发一致性时开启事务。
  3. 在事务内保持查询和写入最少，完成后立即提交。
  4. 把远程 API、短信、推送、文件处理等慢或不可回滚的外部 I/O 放到事务外；需要可靠副作用时使用提交后的事件或队列方案。

What it can do on your machine

Read from SKILL.md and the folder at commit 3f10589. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are php).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Validate Then Transact loads about 311 tokens when it runs. Until then it costs about 28 tokens; SKILL.md has 28 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~28
When it runs · the whole SKILL.md, loaded when a task matches
~311

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

ThinkPHP 校验与事务边界

默认顺序

  1. 在事务外完成参数格式、权限、静态业务规则和不依赖锁的存在性检查。
  2. 只在需要原子多表写入或并发一致性时开启事务。
  3. 在事务内保持查询和写入最少，完成后立即提交。
  4. 把远程 API、短信、推送、文件处理等慢或不可回滚的外部 I/O 放到事务外；需要可靠副作用时使用提交后的事件或队列方案。
php
$this->validateBusiness($data);

return $this->transaction(function () use ($data): int {
    $model = $this->model();
    $model->save($data);
    return (int) $model->id;
});

并发校验例外

“先校验再事务”不等于禁止事务内校验。余额、库存、订单状态、退款额度等值可能在事务外检查后被并发修改，必须在事务内重新读取可信当前状态：

php
return $this->transaction(function () use ($id): bool {
    $row = $this->model()->where('id', $id)->lock(true)->find();
    if ($row === null) {
        throw new BusinessException('记录不存在');
    }
    if (!$this->canTransit((int) $row->status)) {
        throw new BusinessException('当前状态不允许操作');
    }
    return $row->save(['status' => 2]);
});

在热点计数或库存扣减中，优先使用带条件的原子 UPDATE，再根据受影响行数判断是否冲突。唯一约束、条件更新和行锁是并发下的最终防线，事务外预检不能替代它们。

禁止项

  • 不为单表单次写入机械地扩大事务范围。
  • 不在持锁事务内调用外部服务或执行可长时间阻塞的工作。
  • 不只依赖事务外读取做状态流转、余额或库存判断。
  • 不吞掉事务异常后返回成功。

自检

  • 可提前完成的校验已移到事务外。
  • 依赖锁内当前值的校验已在事务内重做。
  • 事务覆盖的写入具有同一原子目标。
  • 外部副作用不会因回滚而与数据库状态分叉。
