hunting-business-logic-flaws skillA

hunting-business-logic-flaws is agent-read markdown (skill) from unboundcompute/security-agent-skills: Hunt for vulnerabilities that live in what an application is allowed to do, not in how it is coded: workflow steps that can be skipped or reordered, quantity/price/limit values that go negative or overflow a cap, state transitions that should be unreachable, replay and concurrency abuse, and privileged outcomes reached through a sequence of individually-valid requests. Use when reviewing checkout, transfers, redemption, quotas, or any rule the code enforces implicitly. These are the flaws static.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add unboundcompute/security-agent-skills/hunting-business-logic-flaws@git:20260816.a6124f2
Exact content
mdr add unboundcompute/security-agent-skills/hunting-business-logic-flaws@sha256:6ff81db2ab91657d

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
