rust-ecosystem-crates skillA
rust-ecosystem-crates is agent-read markdown (skill) from fusengine/agents: Use when choosing crates for a Rust project — serialization, CLI, async runtime, web, database, HTTP client, error handling, observability. Not for API usage details of an already-chosen crate..
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.
What the file says
<objective> This skill provides a domain-to-crate decision map of the de-facto 2026 Rust ecosystem standards — serde for serialization, clap for CLI parsing, tokio for async, axum for web, sqlx/sea-orm/diesel for database access, thiserror/anyhow for error handling split by library vs application, and tracing for observability — plus the selection criteria behind each choice. It also covers matching an existing project's Cargo.toml conventions before introducing a competing crate, and the version-verification discipline (never trust a remembered patch number; confirm current versions on crates.io/Context7/Exa). Out of scope: once a crate is chosen, its detailed API usage belongs to the matching domain skill (rust-web-backend, rust-async-concurrency, rust-error-handling) or direct docs verification (docs.rs/crates.io → Context7 → Exa). </objective> # Rust Ecosystem & Crates ## Agent Workflow (MANDATORY) Before ANY crate selection, spawn 3 agents in parallel, one `Agent` call each with a `name`: 1. **fuse-ai-pilot:explore-codebase** - Read existing `Cargo.toml` to match established choices …

How to install
mdr add fusengine/agents/rust-ecosystem-crates@git:20260904.5f1d30fmdr add fusengine/agents/rust-ecosystem-crates@sha256:8b033e5ff983c2a2Pin 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.
