shacl-compact-syntax SKILL.md skillA
shacl-compact-syntax from sparq-org/sparq is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Parse or write SHACL Compact Syntax (SHACL-C/SCS) shapes with the opt-in sparq-shaclc Rust crate. Use when converting strict W3C CG syntax or shaclc-js extended syntax to oxrdf triples, building a sparq-shacl validation graph, handling typed source errors, using the generated streaming parser, or faithfully serialising an expressible shapes graph back to compact syntax.
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
# SHACL Compact Syntax
Use `sparq-shaclc` as a separate opt-in parser/writer crate. Its crate-root API
emits `oxrdf::Triple` values; add `sparq-shacl` only when the resulting shapes
must be validated against data.
<!-- PR #2136: public usage surface for sparq-shaclc. -->
## Parse shapes
`Cargo.toml`:
```toml
[dependencies]
sparq-core = { path = "../sparq-core" }
sparq-shaclc = { path = "../sparq-shaclc" }
sparq-shacl = { path = "../sparq-shacl" } # only for validation/Graph conversion
```
Parse strict SHACL-C and turn the triples into a validation-ready shapes graph:
```rust
use sparq_core::Graph;
use sparq_shaclc::{parse_strict, DEFAULT_BASE};
let source = r#"
PREFIX ex: <http://example.org/>
shape ex:PersonShape -> ex:Person {
ex:name [1..1] xsd:string .
}
"#;
let (triples, outcome) = parse_strict(source, DEFAULT_BASE)?;
let shapes = sparq_shacl::graph_from_triples(triples);
let data = Graph::load_str("@prefix ex: <http://example.org/> . ex:a a ex:Person .", "turtle")
.expect("valid Turtle data");
let report = sparq_shacl::validate(&data, &shapes);
assert!(!report.conforms);
assert_eq!(outcome.base, DEFAULT_BASE);
# Ok::<(), Box<dyn std::error::Error>>(())
```

How to install
mdr add sparq-org/sparq/shacl-compact-syntax@sha256:9ec27d0039e7c4ddThe line at the top of this page pins the label git:20261009.f0b870d, 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.
