rust-safety SKILL.md skillA
rust-safety from lu1sdv/skillsmd is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add lu1sdv/skillsmd/rust-safety@git:20261103.3acb4abPins git:20261103.3acb4ab in mdr.lock. Pin the fingerprint instead.

Use when auditing Rust safety or security, writing unsafe abstractions or C FFI/C-ABI bridges to C++, or investigating panic- or recursion-driven denial of service, resource/raw-handle ownership, untrusted input, filesystem/process boundaries, or concurrency invariant failures. Covers soundness proofs, MaybeUninit, Drop, Send/Sync, ABI/layout, C strings, allocator ownership, callbacks, FFI unwinding, Rust 2024 unsafe syntax, cancellation, and Miri/sanitizer evidence. Not a general Rust…
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
# Rust Safety and Security Review the invariant and its observable consequences, not the presence of `unsafe`, `unwrap`, or a suspicious API. Safe Rust can have availability and logic vulnerabilities; a soundness defect is not automatically a remote exploit. ## Quick reference: load only the relevant guide | Task or symptom | Read | First question | |---|---|---| | Raw pointers, provenance, unions, packed fields | [Safety and initialization](references/safety-and-initialization.md) | Can a safe owner/slice express it; if not, what proves the raw operation? | | `MaybeUninit`, manual allocation, panic during `Drop` | [Safety and initialization](references/safety-and-initialization.md#initialization-and-destruction) | What remains live and initialized on every exit? | | Unsafe traits, hostile safe callbacks, pinning | [Safety and initialization](references/safety-and-initialization.md#unsafe-traits-and-pinning) | Can any safe client break the invariant? | | C ABI/layout, strings, foreign ownership, callbacks | [C boundaries](references/c-boundaries.md) | Who owns the allocation, and when does foreign access end? | …

How to install
mdr add lu1sdv/skillsmd/rust-safety@sha256:4e5a66cecc75c312The line at the top of this page pins the label git:20261103.3acb4ab, 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.
