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 | $0.00059 | $0.01882 |
| Opus 5.5 | $0.00024 | $0.00753 |
| Sonnet 5.5 | $0.00012 | $0.00376 |
| Haiku 4.5 | $0.00006 | $0.00188 |
Grade A, and why
deepxiv-fa-uk-eu-law 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 5d 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.

The opening of the file, as written. The whole thing — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.
DeepXiv · UK & EU Law (uk_eu_law)
About 52k UK and EU legal instruments (synced daily; exact counts in corpus): about 42.4k EU (EUR-Lex — REG / REG_IMPL / DEC / DIR) plus about 9.3k UK (legislation.gov.uk — ukpga / asp / nia / asc / nisr / ssi / ukla; scanned-PDF-only items and pre-1837 items without text are excluded). Norm types (the same closed set as us_law), regulated parties, penalties, defined terms, deadlines, cross-references and bilingual summaries are model-extracted. Hybrid vector + lexical search; filters and sorting in Postgres.
Corpus: 51,737 documents.
Setup
pip install -U deepxiv-sdk # deepxiv registers a token on first use
With a registered key (https://data.rag.ac.cn/register), search and read are fair use: 60/min, 5 at once, 5,000/day; on the auto-registered token they spend the deepxiv daily limit at the credits listed below. ask draws on the daily ask allowance (resets 00:00 UTC; a site-wide daily total can run out early at peak times), or 3 lifetime trial asks on the auto-registered token. On 429, back off for Retry-After seconds. Data goes to stdout; cost, quota and sources go to stderr. Exit 0 ok, 1 API error, 2 usage error. The general CLI guide is the deepxiv-cli skill.
Start here
deepxiv fa search uk_eu_law "data protection" -F jurisdiction=eu -k 5
deepxiv fa search uk_eu_law "artificial intelligence high-risk systems" -F kind=REG -F "year>=2020" -k 5
deepxiv fa read uk_eu_law eu:32016R0679 -l brief # GDPR
deepxiv fa ask "Under the GDPR, when may personal data be transferred to a third country?" -d uk_eu_law

Search
deepxiv fa search uk_eu_law "query" [-F FILTER]... [-k N] [--offset N] [--mode M] [--sort S] [--head] [--json]
Modes: hybrid, dense, bm25, keyword. Up to 200 hits. Cost 2 (with --head: 3).
Sorts: relevance, date (default relevance).
An empty query is rejected; use "*" to list by filters only. Filters combine with AND; an undeclared field exits 2.
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.

deepxiv-fa-uk-eu-law is a skill published in the GitHub repository DeepXiv/deepxiv_sdk (838 stars, last pushed 6d ago), licensed MIT. It adds 59 tokens to every session and 1,882 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-10-20.

Freedom-to-operate triage — a structured first look at potentially blocking patents, not an FTO opinion. Use when a product, process, or feature is being evaluated for blocking patents, when asked whether anything stops a launch, or to build a claim-chart first pass against the most plausible patents before patent…
legal-hold
Issue, refresh, release, or report on legal holds — drafts the hold notice as .docx, updates legalhold fields in log.yaml, and calendars the next refresh. Use when the user says "issue a hold", "refresh hold", "release hold", or asks for a portfolio-wide hold status report.
