reqvire-concept-authoring

reqvire-concept-authoring is a skill for Claude Code, Codex from reqvire-org/reqvire. It costs 116 tokens per session (3,048 once invoked), scanned A, original, Apache-2.0.

A tool for creating and revising controlled vocabularies: organized lists of terms with definitions, relationships, and mappings. Reqvire and SKOS are systems for representing this kind of shared terminology.

In plain words
What is it for?
It is for authoring concept schemes, definitions, synonyms, broader and narrower terms, related concepts, and mappings.
Why use it?
It helps teams keep terminology consistent and describe how concepts relate to one another.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

reqvire-concept-authoring scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Reqvire Concept Authoring

Author curated terminology as native Reqvire Markdown elements, not as SKOS Turtle inside ontology elements. Reqvire generates skos:ConceptScheme and skos:Concept RDF from concept-scheme and concept elements.

Use this skill for thesaurus work: stakeholder terminology, controlled vocabularies, synonyms, definitions, broader/narrower taxonomy, related concepts, concept mappings, and concept references from capabilities, requirements, contracts, or verifications.

Use reqvire-ontology-authoring instead when the work is structural OWL/RDFS vocabulary, classes, properties, individuals, axioms, SHACL targets, or semantic contracts.

Use reqvire-syseng instead when the main change is to capabilities, requirements, specifications, verification elements, evidence, coverage, change-impact workflows, or broader model refactoring. This skill may update concept references on those elements only as part of concept-authoring work.

Reqvire Operations for Concept Authoring

Use Reqvire as the source-of-truth runtime when authoring or changing native concept schemes and concepts.

  • Work from the intended effective workspace root unless the user gives a different workspace; the workspace must contain at least one eligible Git worktree.
  • Default CLI form: npx -y "${REQVIRE_NPX_PACKAGE:-@reqvire-org/reqvire@latest}" --workspace "$PWD" <command>.
  • Inside the Reqvire source repository, cargo run -- <command> is also acceptable when the local binary is the intended target.
  • Inspect authored concepts with search --filter-type concept-scheme --json, search --filter-type concept --json, model --filter-type concept-scheme --json, semantic export --layer concepts, concepts export, and concepts validate.
  • Use semantic export --layer ontologies --layer concepts when checking authored structural reqvire:mapsToConcept bridge triples together with generated native SKOS concepts. Use semantic export --layer model when checking downstream graph-store model facts.
  • Prefer Reqvire CLI mutation commands for broad structural edits when available, such as add, link, relink, mv, mv-file, mv-folder, rm, and rename-element.
  • Manual Markdown edits are valid for focused authoring. Preserve # Elements, ### Element Name, #### Metadata, and Reqvire relation list syntax.
  • Place concept-scheme and concept elements under system-model/Thesaurus unless the existing project uses a different system-model/ content structure.
  • Author concept-scheme elements with type: concept-scheme, concept_base, and concept_prefix; this element is the namespace and SKOS ConceptScheme holder.
  • Author concept elements with type: concept; the main body is the SKOS definition-like human explanation. Do not add #### Details, #### Ontology, #### Shapes, #### Definition, or #### Top Concepts to concept elements.
  • Use #### Labels, #### Scope Note, #### Examples, and #### Mappings for SKOS-specific concept authoring fields when needed.
  • Use #### Relations for Reqvire-authored links: derivedFrom for scheme/parent containment, broader / narrower for taxonomy, related for associative links, and exactMatch / closeMatch for intentional concept-to-concept mappings.
  • Relation syntax is * relationName: [Target Element](path.md#target-element).
  • Keep ontology-to-concept bridges in ontology Turtle with reqvire:mapsToConcept; do not model those bridges as concept Markdown fallback data.
  • When changing concept identity, check dependent ontology bridges, concept references, Explorer thesaurus data, MCP concept tools, and any tests that assert generated SKOS IRIs.
  • When validation is part of the task, run focused checks such as validate, semantic export --layer concepts, concepts validate, and any affected fixture tests before finishing.
