Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00083 | $0.00587 |
| Opus 5 | $0.00042 | $0.00293 |
| Sonnet 5 | $0.00017 | $0.00117 |
| Haiku 4.5 | $0.00008 | $0.00059 |
Grade A, and why
rdf-det-variant-generator 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 12d 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.

RDF DET Variant Generator
Use this skill when building a custom DAV DET derived from the RDFImport pattern for RDF-bearing document types supported by Virtuoso.
What This Skill Produces
- DET SQL scaffolding derived from
RDFImport - Hook coverage checklist for required
DB.DBA.<DetName>_DAV_*functions - Variants for multiple RDF document types
- Verification SQL and WebDAV probes
- Packaging guidance for:
{HOME}/Documents/Management/Development/virtuoso-engine/binsrc/yacutia/sql/{HOME}/Documents/Management/Development/ods-virtuoso/briefcase/sql/
Trigger Conditions
Use this skill when the user asks to:
- create a DET similar to RDF Import
- support additional RDF document types
- generate a new Quad Store ingestion DET
- scaffold a DAV DET that loads RDF into named graphs
- create or update DET SQL hooks and validation queries
Workflow
⛔ PRE-BUILD CHECK: Before producing output, re-read the relevant workflow section above and re-read any checklists or verification gates defined in this skill. Confirm each checklist item before writing output. Build to pass — do not retro-fit. Apply the CLAUDE.md Anti-Drift Protocol: re-read spec section before build, gate-first validation, section-by-section delivery.
- Identify the DET name, target folders, and desired graph behavior.
- Confirm the RDF document types to support.
- Load the implementation checklist in
references/det-hook-checklist.md. - Load the RDF-type guidance in
references/virtuoso-rdf-doc-types.md. - Use
references/rdf-det-template.mdto generate or update the DET. - Generate validation queries from
references/verification-queries.md. - Provide VAD/source integration notes and release/build reminders.
Output Requirements
- Keep runtime SQL in Virtuoso procedure form.
- Keep verification artifacts separate from runtime code.
- When generating listing logic, prefer explicit vector accumulation unless there is a proven reason to use builder helpers.
- Ensure the DET returns a proper array of DAV row vectors from
_DAV_DIR_LIST.
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

rdf-det-variant-generator is a skill published in the GitHub repository OpenLinkSoftware/ai-agent-skills (38 stars, last pushed today), licensed MIT. It adds 83 tokens to every session and 587 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
