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 | $0.00219 | $0.04773 |
| Opus 5.5 | $0.00088 | $0.01909 |
| Sonnet 5.5 | $0.00044 | $0.00955 |
| Haiku 4.5 | $0.00022 | $0.00477 |
Grade A, and why
alterlab-citation-verifier 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 1mo 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 328 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Citation Verifier — Existence-Verify a Bibliography Against Public Scholarly APIs
The headline existence-verification skill: given a bibliography in any common
form, it proves entry-by-entry whether each reference actually exists by
querying public scholarly APIs, then maps each result to the canonical AlterLab
citation-hallucination taxonomy. It is the deterministic, network-grounded
companion to the LLM-driven integrity_verification_agent — where that agent
uses WebSearch + judgment, this skill uses authoritative API records and a
reproducible Python script, so every verdict rests on retrieved records and the
same input and source responses yield the same verdicts.
Verify references with the script, not from memory. A model checking citations against what it "remembers" shares the training data that produced the hallucination in the first place, so a fabricated reference that feels right passes undetected; only an external record settles existence.
Quick Start
Verify the citations in references.bib
Check whether these DOIs resolve to the papers I cited
Audit my bibliography for fabricated / hallucinated references
Does this reference list contain any fake citations or retractions?
→ Run scripts/verify_citations.py over the bibliography, read the JSON, then
present a verdict table grouped by severity. State the offline/degraded status
explicitly if the network or a source was unavailable.
When to Use This Skill
- "Verify / check / audit my citations or references exist"
- "Did the AI hallucinate any of these references?" / "Is this DOI fake?"
- "Do these DOIs resolve to the papers I cited?"
- "Check this bibliography for retractions"
- "Does this source actually support the sentence I cite it for?" (SH, abstract level)
- A reproducible, scriptable existence check with an explicit offline mode
Does NOT Trigger
| Scenario | Use Instead |
|---|---|
| Writing or revising the paper itself (its citation-check mode formats citations) | alterlab-paper-writer |
| Finding papers, extracting metadata, or generating BibTeX for new sources | alterlab-citation-mgmt |
| Dead or redirected hyperlinks (link rot) in docs or a reference list | alterlab-link-health |
| Full pre-/post-review integrity gate (citation context, data, originality) | alterlab-research-pipeline |
| Holistic peer review of a manuscript with an editorial decision | alterlab-paper-reviewer |
What ships with it
6 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.

alterlab-citation-verifier is a skill published in the GitHub repository AlterLab-IEU/AlterLab-Academic-Skills (78 stars, last pushed 4d ago), licensed MIT. It adds 219 tokens to every session and 4,773 once invoked, about $0.0009 per session on Opus 5.5. 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 2026-09-03.
