nextclaw: Skill for Codex

.agents/skills/development-review/SKILL.md

development-review is a skill for Codex from Peiiii/nextclaw. It costs 50 tokens per session (1,637 once invoked), scanned A, original, MIT.

A code-review process for deciding whether completed and tested changes are safe to accept. It examines behavior, risks, contracts, tests, and maintainability, where maintainability means how easy the code is to understand and change.

In plain words
What is it for?
Use it to review source code, scripts, tests, runtime configuration, pull requests, or proposed fixes. It can also run a focused check on changed files for maintainability problems.
Why use it?
It finds correctness problems, regression risks, unnecessary complexity, duplicated logic, and missing protection for real failures before delivery. It keeps reviewers focused on evidence rather than personal style preferences.

Skill for Codex

Written for Codex: agents/openai.yaml present. Also seen: installed under .agents/ (shared by several agents).

This is Peiiii/nextclaw's own configuration. It tells Codex how to work on nextclaw 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 nextclaw 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

development-review 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 29d ago.

The scan reads SKILL.md. This mod also ships 10 executable files (scripts/check-maintainability.mjs, scripts/maintainability-guard-core.mjs, scripts/maintainability-guard-directory-budget.mjs, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Development Review

目标

先明确 mode=design 或 implementation,不因尚无代码跳过方案审查。两个 mode 都按证据输出 findings,由总流程决定下一步。

方案 Review(mode=design)

检查目标覆盖、现有能力复用证据、owner/主链路唯一性、重要反例、失败边界、可行性,以及验收是否会放过不完整结果;缺证据即 finding,方案自洽不等于成立。 新项目、技术栈替换及新增关键运行/部署依赖,核对 Design 的技术决策是否有需求/环境依据、真实替代项的取舍(有分叉时)及关键可行性证据;仅列技术名称、凭习惯选择或将必要选择留到编码时均返回 Design。沿用小改与用户指定选择按其适用边界检查,不强制凑候选或追加审批。 从原用户目标独立核对设计的交付与黄金验收使用链路,不仅检查方案自洽:逐步走查动作、系统反馈、继续操作和最终判定,检查交付前提能否落实、AI 自验与用户判断是否分清。只有入口/测试清单、需要审查者补步骤,或全部测试通过仍拿不到原用户结果时,返回 Design。豁免必须符合任务范围与用户行为不变的事实,不能仅因没有 UI、改动在底层或尚未发布而成立;纯内部和用户明确限定的产物交付不强加运行环境。 大型交付从日志的原始输入记录定位相关原件,核对用途、版本、有效修订与必要阶段边界;检查本部分书面方案的“来源 → 有效要求 → 设计 → 验证”对应关系,不能仅检查 AI 的提炼。功能/交互要求不能因原件是 HTML 就降为样式参考;明确只是参考的部分也不自动升级成硬约束。漏项、未解释偏差、缺当前部分书面设计或待决提案冒充有效约定均是 finding。实现 Review 从产物反查同一来源与已确认变更,不能靠实现、测试和后来改写的标准相互一致放过漂移。结论关联对象版本和证据,复用原日志,不另建验收表。

跨架构设计按合同的旧能力/用户目标/候选能力双向对账,独立核对原始来源和旧新真实入口。先确认方案覆盖当前有效目标;旧→新有未解释的用户可见变化,或目标→新有必需能力被列为未来、没有可触发入口或完整使用场景,都是 finding。其它分支的成功测试不能抵销。

性能或成本列为 Required 时,检查门槛是否在实现前按可复现条件固定,候选比较与验收是否覆盖真实用户等待、代表使用量和关键冷/热分支;只有理论推断或单次最佳值是 finding。不因当前任务没有性能取舍而要求例行压测。

核对本次拟实现部分是否已具体设计;整体设计允许后续细节待定,但不得遗留影响当前实现的未决选择。通过结论标明适用范围,不扩展到未审查的待细化部分。问题给出对应设计位置、影响和修正方向;未关闭 finding 返回 Design,通过返回 design-review: passed。后续补充或改变设计后审查受影响部分。不运行代码维护性脚本,不要求子代理,不复制完整方案。以下环节仅适用于 implementation。

进入

  • 有实现产物时,在验证证据稳定后进入;
  • 用户明确要求代码 review、PR review、风险扫描或拟议修复评审时可直接进入;
  • 纯文档、措辞和普通元信息只做内容、结构和 diff review,不运行代码维护性脚本;
  • 普通局部改动使用轻量 review,L3-L4、跨模块、结构大改或用户明确要求时执行完整 findings-first review。

自动检查

源码、脚本、测试或运行链路配置改动先运行一次项目已有的 diff-only maintainability 检查;项目没有该检查时直接按下面的 findings-first 方法审查,不为满足流程临时发明脚本。项目检查的预算、参数与阻塞级别由项目自身定义。不得为消除普通净增长扩大无关范围、压缩可读性或删除类型/协议保护。

Findings-first 审查

  1. 明确 diff、触达文件、相邻合同和受影响测试。
  2. 重建改动前后真实用户或调用方可观察行为。
  3. 优先检查正确性、边界、状态迁移、异步、数据流、API/UI 合同和运行失败模式。
  4. 判断测试是否保护稳定外部行为;只有真实回归路径缺保护时才把缺测试列为 finding。
  5. 检查改动是否把单次实例抬成全局机制、把局部经验固化为公共合同,或让抽象层级高于证据;同时检查重复真相、隐藏 fallback、无收益抽象,以及小 diff 保留的错误 owner、重复生命周期和确定迁移债。
  6. 双向比较删除无收益路径与继续压缩造成的欠设计,按全生命周期净复杂度选择修正,不预设抽象或最小改动为答案。
  7. 对重复 UI 骨架判断是否应采用共享骨架、类型化配置和薄壳组合。
  8. 输出按严重级别排序的 findings、证据、风险和可信修复方向。

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.
