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 | $0.00057 | $0.01910 |
| Opus 5.5 | $0.00023 | $0.00764 |
| Sonnet 5.5 | $0.00011 | $0.00382 |
| Haiku 4.5 | $0.00006 | $0.00191 |
Grade A, and why
deepxiv-fa-osv 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.
How it starts
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 · OSV (osv)
About 200k open-source package security advisories — the part of osv.dev that CVE does not cover (synced daily; exact count in corpus). Over 90% are malicious-package reports (MAL-*, overwhelmingly npm); the remaining ~13k are standalone advisories with no CVE id (GHSA / RUSTSEC / PYSEC / GO …). Malicious behaviours (closed set of 13), the legitimate package being impersonated, IOCs (domains / URLs / IPs / filenames, each verified to appear in the advisory text) and one-line summaries are model-extracted. Hybrid vector + lexical search; filters and sorting in Postgres.
Corpus: 199,701 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 osv "malicious npm package credential theft" -F malicious=true -F ecosystems=npm -k 5
deepxiv fa search osv "*" -F behaviors=credential_theft --sort published -k 5
deepxiv fa read osv MAL-2026-17452 -l brief
deepxiv fa ask "Are there malicious npm packages impersonating popular crypto libraries?" -d osv
Free samples: ids MAL-2026-17452; queries malicious npm package.
Search
deepxiv fa search osv "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, published (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-osv is a skill published in the GitHub repository DeepXiv/deepxiv_sdk (838 stars, last pushed 6d ago), licensed MIT. It adds 57 tokens to every session and 1,910 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.
