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.

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 | $0.00147 | $0.05362 |
| Opus 5 | $0.00073 | $0.02681 |
| Sonnet 5 | $0.00029 | $0.01072 |
| Haiku 4.5 | $0.00015 | $0.00536 |
Grade A, and why
eu-sparql-search scanned grade A with 1 finding 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

EU SPARQL Search - Cellar / EUR-Lex
Endpoint
https://publications.europa.eu/webapi/rdf/sparql
Accepts HTTP GET and POST. Key parameters:
query- SPARQL query string (URL-encoded)format- output format (see below)timeout- milliseconds (use ~30000 for safety)
CDM Data Model
Every document exists at 4 levels:
Work <- abstract document (e.g. "Regulation 2016/679")
Expression <- language version (e.g. Polish, English)
Manifestation <- file format (pdfa2a, fmx4, xhtml)
Item <- downloadable file URL
Main ontology prefix: cdm: -> http://publications.europa.eu/ontology/cdm#
Standard Prefixes (include in every query)
PREFIX cdm: <http://publications.europa.eu/ontology/cdm#>
PREFIX annot: <http://publications.europa.eu/ontology/annotation#>
PREFIX skos: <http://www.w3.org/2004/02/skos/core#>

What ships with it
1 file 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.

eu-sparql-search is a skill published in the GitHub repository matematicsolutions/awesome-matematic-skills-pl (6 stars, last pushed 19d ago), licensed MIT. It adds 147 tokens to every session and 5,362 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
