rust-macros SKILL.md skillA
rust-macros 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-macros@git:20261011.8d24f4cPins git:20261011.8d24f4c in mdr.lock. Pin the fingerprint instead.

Use when writing or debugging Rust macro_rules! matchers, repetitions, hygiene, $crate exports, edition-dependent fragments, or procedural derive, attribute, and function-like macros using syn and quote; includes expansion and diagnostic tests.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Rust Macros ## Quick reference | Task or symptom | Action | Load | |---|---|---| | Ordinary reusable logic | Use a function; generics for type abstraction | Optional rust-idiomatic or rust-api-design skill | | Variable syntax, repeated declarations | Start with `macro_rules!` and an explicit grammar | [Declarative macros](references/declarative.md) | | `local ambiguity`, invalid fragment follower | Add a delimiter/tag; inspect fragment follow sets | [Declarative macros](references/declarative.md) | | Works locally, fails downstream | Inspect `$crate`, helper visibility, imports, renamed dependencies | [Declarative macros](references/declarative.md) | | Derive, item transformation, parsed DSL | Separate proc-macro crate; parse → validate → generate | [Procedural macros](references/procedural.md) | | Wrong bound or inscrutable derive error | Preserve generics; field-specific bounds and input spans | [Procedural macros](references/procedural.md) | | Suspected bad expansion | Compile smallest caller, inspect expansion, test semantics | [Testing and traps](references/testing.md) | …

How to install
mdr add lu1sdv/skillsmd/rust-macros@sha256:77d3ec037b093e42The line at the top of this page pins the label git:20261011.8d24f4c, 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.
