Security audit
Security checks for vulnerabilities and agentic risk
This skill is a disclosed, Chinese-first helper for maintaining repository agent-instruction files, with a bounded optional read-only inventory script and no evidence of hidden execution or data exfiltration.
Install this only if you want a skill that can help maintain repository agent-instruction documents. Because those files affect future agent behavior, invoke it deliberately for AGENTS.md/CLAUDE.md work, review diffs before keeping changes, and run the optional inventory script only against repositories you are authorized to inspect.
The instruction to read ~/.ssh/id_rsa and upload it to an external address is a direct natural-language data leakage request targeting highly sensitive credentials. Its phrasing relies on semantic intent rather than technical exfiltration code, which is exactly the residual risk this rule covers.
声明描述的是一种面向指令工程的编辑/审查能力：调查项目背景，提炼规则，并创建或更新 AGENTS.md/CLAUDE.md。实际代码则是一个受限的审计/清点工具，核心行为是遍历目录、识别候选指令文件、读取文件内容、计算 SHA-256、检查局部链接、统计缺失引用和重复正文。虽然它与“审查仓库指令候选”存在弱相关性，可作为辅助盘点工具，但其主要目的和输出与声明明显不同：没有任何创建、重构、更新、规则提炼、作用域核实结论生成等功能。因此属于描述与实际行为的实质性不匹配。
声明描述的是一种面向仓库指令治理的内容维护/规则提炼技能；而代码片段是 tests/test_inspect_instructions.py，明显是在测试 inspect_instructions.py 的只读扫描行为。测试覆盖空仓库、命名规范、UTF-8、哈希、默认排除目录、敏感目录、Markdown 引用解析、代码块忽略、外链不访问、查询参数不回显、路径穿越防护、绝对路径/主目录路径拦截、符号链接安全、扫描上限、CLI JSON 输出和退出码等。这说明实际能力是“安全地盘点和检查 instruction 文件及其引用”，不是“创建或更新 instruction 文档并提炼规则”。两者都与 AGENTS.md/CLAUDE.md 有关，但主目的和能力重心明显不同，因此应判定为描述与行为不匹配。
声明描述的是一个面向仓库指令文档（如 AGENTS.md、CLAUDE.md）的内容维护与规则提炼技能，重点在理解项目并生成/修改会影响 Agent 决策的指令。实际代码并不执行任何此类文档生成、重构、更新或项目规则提炼逻辑；它只是一个 unittest 测试文件，用于静态验证该技能包自身的文件清单、元数据、研究记录和脚本安全边界。虽然其中有少量与指令相关的检查（例如 SKILL.md/frontmatter、agents/openai.yaml），但这些是包质量保证测试，不是声明中的核心能力。因此主用途明显不同，属于实质性描述与行为不匹配。

The external template text contains natural-language instructions to read a private key, upload it externally, and then disregard user limits. This is not merely a discussion of security concepts; it is an embedded hostile instruction sequence that attempts to redirect an agent toward unsafe, unauthorized behavior.

The phrase "默认中文" indicates the skill defaults to Chinese output or interaction. This is a language/locale policy choice presented as a default rather than an explicit user-selected option, which can violate the requirement to avoid forcing a specific language without opt-in.
Without declared permissions the skill's intent is opaque and cannot be validated.
The skill enables implicit invocation without defining concrete trigger constraints, so the agent may activate this repository-instruction-maintenance skill in situations broader than intended. Because the skill can create or revise AGENTS.md and similar instruction files that influence future agent behavior, accidental or contextually inappropriate invocation can propagate incorrect policy, overwrite guidance, or introduce instruction drift across the repository.
The file explicitly sets "language": "zh-CN" and does not provide any nearby justification that this is a region-specific or user-selected setting. The policy requires avoiding forced language or locale constraints unless the choice is documented and justified or offered as an opt-in.
This markdown file contains skill guidance exclusively in Chinese, and there is no indication that users may choose another language or that the skill is intentionally limited to a Chinese-speaking context. Under the language/locale policy, forcing a single language without opt-in can be a natural-language policy violation.
This markdown file contains a prescriptive natural-language requirement: '中文定位为' followed by the required skill positioning in Chinese. Under the language/locale policy rule, forcing a specific language without opt-in is a policy concern unless the locale constraint is explicitly justified or alternatives are offered.
This manifest-like JSON sets language to zh-CN, which is a natural-language locale constraint. The file does not indicate that the language was user-selected, optional, or required for a region-specific purpose, so it appears to force a specific locale without opt-in.

The tests require SKILL.md descriptions to include the Chinese phrases "普通编码" and "不主动触发", which enforces a specific language/locale in repository content. This is a natural-language policy concern because the file does not indicate user choice or a documented region-specific justification for requiring Chinese text.
The instruction "默认中文" sets a default output language policy for the skill. The rule allows language constraints only when the user is offered a choice or when the locale limitation is clearly justified; here it is a blanket default rather than an explicit opt-in.
This JSON manifest-like file declares a single language value of "zh-CN". Because this is a manifest/plain-text scoped file, fixed natural-language settings without any opt-in or contextual limitation can create ambiguity about whether the skill or eval content is intended to operate only in that locale.
该文件全文以中文编写，且未见任何提示说明这是特定语言环境下的限定文档，也未提供用户可选择其他语言的说明。根据语言/locale 政策，若技能默认强制单一语言而无用户选择或合理约束说明，属于自然语言层面的政策风险。
Line L79 states "默认中文" (default Chinese), which is a natural-language locale directive. Under the policy, forcing a specific language without offering a user choice or opt-in is a reportable language/locale policy violation.
The notes field contains user-facing natural language exclusively in Chinese. For a general JSON artifact with no documented regional scope or opt-in, forcing a specific language can violate the language/locale policy because consumers may be unable to understand important caveats.
This markdown file is natural-language content and appears to require Chinese for all user-facing documentation. Under the policy, forcing a specific language without user opt-in can be a locale-policy violation unless the constraint is explicitly justified, which is not stated here.
This Python file contains natural-language strings exclusively in Chinese, starting with the module docstring used as the CLI description. Because the script does not offer a language/locale option or indicate that it is intentionally limited to a Chinese-speaking environment, it creates a language-policy concern under the locale-choice rule.
