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 | $0.00078 | $0.01190 |
| Opus 5 | $0.00039 | $0.00595 |
| Sonnet 5 | $0.00016 | $0.00238 |
| Haiku 4.5 | $0.00008 | $0.00119 |
Grade A, and why
citecheck 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 6d 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 — 144 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CiteCheck — Paper Citation Verification
Overview
CiteCheck verifies academic paper citations by combining structured parsing with agent-native LLM evaluation. It supports LaTeX source files (preferred) and PDF fallback.
Workflow
- Parse paper: Call
citecheckCLI to read LaTeX (preferred) or PDF, extract references and body text - Format check: Call
citecheckCLI to validate bibliography entries - Queryability verification: Call
citecheckCLI to verify existence via Crossref / Semantic Scholar - Evaluate thematic relevance: Evaluate directly using the agent's reasoning capabilities — compare cited paper title/abstract/venue against the citing paper
- Evaluate semantic accuracy: Evaluate directly using the agent's reasoning capabilities — compare in-text citation context against cited source content
- Generate report: Aggregate all results into a Markdown report
Why matching steps are not done by the CLI The
citecheckCLI can run standalone with optional--api-keyfor external LLM-powered matching. When used as a Skill, the host agent itself possesses LLM reasoning capabilities. Direct evaluation is faster, more consistent, and requires no additional API keys from the user.
1. Parse Paper (CLI)
LaTeX source (preferred)
citecheck path/to/latex_project/ --skip-verification --skip-semantic -o parsed_report.md
Or parse a single file:
citecheck main.tex --skip-verification --skip-semantic -o parsed_report.md
PDF (fallback)
citecheck paper.pdf --skip-verification --skip-semantic -o parsed_report.md
--skip-verificationand--skip-semanticare required in Skill mode because steps 3–5 are performed directly by the agent.
2. Format Check (CLI)
Call citecheck to check and report format issues:
| Check item | Description |
|---|---|
| Required fields | Author, title, year, venue completeness |
| Format consistency | Punctuation, capitalization, abbreviation uniformity |
| DOI/URL | If present, whether format is correct and accessible |
| Year sanity | No 202x placeholders, not in the future |
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.

citecheck is a skill published in the GitHub repository color4-alt/CiteCheck (59 stars, last pushed 3mo ago), licensed MIT. It adds 78 tokens to every session and 1,190 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.
