shacl-validation skillA

shacl-validation is agent-read markdown (skill) from sparq-org/sparq: Validate RDF data against SHACL shapes with the sparq engine: SHACL Core constraints (class, datatype incl. the SHACL-1.2 disjunctive list form, cardinality, ranges, paths, logical, node/property, qualified, closed incl. sh:ByTypes, in/hasValue, the SHACL-1.2 list constraints sh:memberShape / sh:uniqueMembers / sh:min+maxListLength / sh:uniqueValuesFor, and the SHACL-1.2 value constraints sh:subsetOf / sh:someValue / sh:singleLine / sh:rootClass with path-valued sh:equals/disjoint/lessThan compa.

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.

How to install

Latest version
mdr add sparq-org/sparq/shacl-validation@git:20260727.c96f5ab
Exact content
mdr add sparq-org/sparq/shacl-validation@sha256:201ef527f406d0d9

Pin 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.
