http3-server SKILL.md skillA
http3-server from sparq-org/sparq is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add sparq-org/sparq/http3-server@v0.1.0Pins v0.1.0 in mdr.lock. Pin the fingerprint instead.

Embed sparq's internal opt-in HTTP/3-over-QUIC bridge into an axum server with rustls 0.23/aws-lc-rs, Quinn, peer ConnectInfo injection, and graceful shutdown.
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
# sparq HTTP/3 server bridge
Use `sparq-http3` when a sparq HTTP server needs a second, encrypted UDP listener that
dispatches into the same `axum::Router` as its existing HTTP/1.1 or HTTP/2 listener. The
crate is internal and unstable (`publish = false`), and its `server` feature is off by
default so Quinn and the pre-1.0 h3 stack do not enter ordinary workspace builds.
## Add the opt-in dependency
```toml
[features]
default = []
http3 = ["dep:sparq-http3"]
[dependencies]
sparq-http3 = { path = "../sparq-http3", optional = true, features = ["server"] }
```
The downstream crate owns certificate/key loading and runtime configuration. Build a
`rustls::ServerConfig` with the aws-lc-rs provider, TLS 1.3, and the exact `h3` ALPN token:
```rust
use std::sync::Arc;
let provider = Arc::new(rustls::crypto::aws_lc_rs::default_provider());
let mut tls = rustls::ServerConfig::builder_with_provider(provider)
.with_protocol_versions(&[&rustls::version::TLS13])?
.with_no_client_auth()
.with_single_cert(certificates, private_key)?;
tls.alpn_protocols = vec![b"h3".to_vec()];
let quic = sparq_http3::quic_server_config(tls)?;

How to install
mdr add sparq-org/sparq/http3-server@sha256:4502b918e914984aThe line at the top of this page pins the label v0.1.0, 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.
