argument-type SKILL.md skillA
argument-type from dannyan/secguard-clang is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Classify argument-type evidence — an explicit pointer cast passes an incompatible object type to a function parameter. Maps to CWE-686.
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
## Function Argument Type Mismatch Analysis (CWE-686 / CERT EXP37-C) `contract_kind: explicit` — the contract is the callee's declared parameter type. ### Evidence Pattern An argument-type candidate has: - **argument_type_mismatch**: A direct call passes an argument that is an **explicit cast to a pointer type**, where the cast's pointed-to object type is incompatible with the source object's type — e.g. `void f(uint *p); bool b; f((uint *)&b);` (the callee reads a 1-byte `bool` as a 4-byte `uint`). Names the parameter type (`uint *`), the argument's pre-cast pointer type (`bool *`), and the explicit cast target. - **explicit_cast**: the cast expression at the call site. - **call_path**: The function is reachable from an entry point. The detector only emits **direct calls** with an **explicit pointer cast**, and only numeric-object reinterpretations: the target provably reads more bytes than the source object holds (bool→uint, uint32→uint64) or changes the representation kind (int↔float). It does **not** flag `void *`, char/byte casts, identical types, or same-size integer reinterpretation — those are legal C boundaries. ### Hint Tokens (Verdict Basis) …

How to install
mdr add dannyan/secguard-clang/argument-type@sha256:d97caebafe465950The line at the top of this page pins the label git:20261017.a78401f, 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.
