rust-type-diagnostics SKILL.md skillA
rust-type-diagnostics 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-type-diagnostics@git:20261103.3acb4abPins git:20261103.3acb4ab in mdr.lock. Pin the fingerprint instead.

Diagnoses advanced Rust type-system failures involving coercion sites, generic coercion barriers, function-item types, reference patterns, implied lifetime bounds, variance, Any downcasts, trait upcasting, and drop checking. Applies when ordinary ownership fixes do not explain an expected/found type mismatch or lifetime constraint. Complements rather than replaces everyday Rust, API design, concurrency, performance, and unsafe/FFI skills.
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 Type Diagnostics Explain the rejected relationship before changing the program. Reconstruct actual and expected types, identify the language rule, and make the smallest safe change that preserves the intended ownership and API contract. ## Scope and routing Use this skill for difficult type relationships, not as a general Rust tutorial. Read only the reference matching the current failure. | Symptom | Inspect | Reference | |---|---|---| | An annotation fixes a mismatch; a generic call rejects a coercible argument | Expected type, coercion site, inferred type parameter and exact trait impl | [Coercions and patterns](references/coercions-and-patterns.md) | | Two functions have the same signature but different types | Function-item identity versus an expected function-pointer type | [Coercions and patterns](references/coercions-and-patterns.md) | | A destructured binding has an unexpected reference layer; a method chain fails | Pattern binding mode, edition, intermediate type and next receiver | [Coercions and patterns](references/coercions-and-patterns.md) | …

How to install
mdr add lu1sdv/skillsmd/rust-type-diagnostics@sha256:d37e085635a217d5The 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.
