rust-web-backend SKILL.md skillA
rust-web-backend from fusengine/agents is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add fusengine/agents/rust-web-backend@git:20260927.43a351cPins git:20260927.43a351c in mdr.lock. Pin the fingerprint instead.

Use when building a REST/HTTP backend in Rust — axum routing, extractors, shared state, middleware, error responses, sqlx database access. Not for raw async/concurrency (rust-async-concurrency).
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
<objective>
This skill covers the 2026 standard Rust web-backend stack: axum 0.8.x routing (including
the /{id} path syntax that replaced /:id) and extractors, sharing state via State<T>,
composing tower-http middleware (trace, cors, timeout, compression), mapping domain errors
to IntoResponse instead of unwrapping in handlers, and sqlx 0.9 database access with
compile-time-checked query!/query_as! (including the .sqlx/ offline cache for CI).
It also names the honest alternatives — sea-orm for an ActiveRecord-style ORM, diesel for a
mature but synchronous alternative needing spawn_blocking — and structured observability via
tracing.
Out of scope: raw async/concurrency primitives (channels, locks, task spawning) belong to
rust-async-concurrency; cross-domain crate selection belongs to rust-ecosystem-crates.

# Rust Web Backend
## Agent Workflow (MANDATORY)
Before building the service, spawn in parallel:
1. **fuse-ai-pilot:explore-codebase** — detect the existing router, state, and DB layer
2. **fuse-ai-pilot:research-expert** — verify current axum/sqlx APIs via Context7/Exa (axum 0.8 changed several APIs)

How to install
mdr add fusengine/agents/rust-web-backend@sha256:2b6f0050f93be221The line at the top of this page pins the label git:20260927.43a351c, 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.
