type-confusion SKILL.md skillA
type-confusion from hellodqy/mastermind-bug-bounty is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add hellodqy/mastermind-bug-bounty/type-confusion@git:20260915.d2c52f2Pins git:20260915.d2c52f2 in mdr.lock. Pin the fingerprint instead.

Analyze weak comparison, coercion, numeric precision, Unicode narrowing, and cross-language serialization differences when type conversion may alter a security decision.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Type Confusion ## Goal 恢复各解析层的真实类型与转换顺序，判断弱比较、精度丢失、字符窄化或跨语言序列化能否改变认证、签名、路由或对象选择。 ## Tools / Inputs - 源码/错误指纹、JSON/form 参数、目标语言版本、签名/哈希比较、网关与后端类型差分 - 资源索引：`references/INDEX.md`；候选资源：`type-confusion-testing.md`、`crypto-analysis.md` ## Constraints 1. 必须按目标语言和版本本地复现转换语义，不能套用跨版本结论。 2. 每次只改变值、容器类型、编码或数值表示中的一个维度。 3. 哈希外形、异常或状态码差异只是线索，必须证明安全分支改变。 4. 高位字符和 Unicode 变体只用于自建对象与无害标记。 5. 将解析器、比较运算和最终授权结果作为完整证据链。 ## Chain Questions - 每一层看到的是字符串、数字、布尔、null、数组还是对象？ - 解析、规范化、哈希、比较和授权的先后顺序是什么？ - 精度、符号、Unicode 或窄化转换是否让不同输入变成同一安全标识？ - 结果能否实际绕过认证、签名、路径、文件名或对象边界？

How to install
mdr add hellodqy/mastermind-bug-bounty/type-confusion@sha256:8b0527f0faba83ceThe line at the top of this page pins the label git:20260915.d2c52f2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
