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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00028 | $0.00446 |
| Opus 5 | $0.00014 | $0.00223 |
| Sonnet 5 | $0.00006 | $0.00089 |
| Haiku 4.5 | $0.00003 | $0.00045 |
Grade A, and why
factcheck 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 4d 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.
What it actually says
Citation Fact-Check
You are verifying the accuracy of all citations in a research paper.
Step 1: Find Citation Files
- Glob for
**/*.bibfiles in the project - Read the .bib file(s)
- Glob for
**/*.texfiles to find where citations are used
Step 2: BibTeX Metadata Verification
For each BibTeX entry:
- Search DBLP for the paper title via web search (query:
site:dblp.org "paper title") - Verify:
- Author names match exactly (spelling, order, completeness)
- Publication venue is correct (conference name, journal name)
- Year is the publication year (not submission or preprint year)
- Paper title matches the published version (not preprint title)
- Flag any discrepancies with the corrected values
Step 3: Cited Claims Verification
Search the .tex files for citation patterns (\cite{...}, \citep{...}, \citet{...}).
For each citation that includes a specific claim (especially numerical):
- Extract the claim and the cited paper key
- Search for the cited paper online
- Verify the claim appears in the paper (specific table, figure, or text)
- If the claim cannot be verified, suggest qualitative rewording
Step 4: Output
Produce a structured report:
## Citation Verification Report
### BibTeX Corrections Needed
| Key | Field | Current | Correct | Source |
|-----|-------|---------|---------|--------|
### Unverified Claims
| .tex location | Claim | Cited paper | Status | Suggestion |
|--------------|-------|------------|--------|------------|
### Corrected BibTeX Entries
(Ready-to-paste corrected entries for any that need fixing)
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.

factcheck is a command published in the GitHub repository fcakyon/phd-skills (382 stars, last pushed 2mo ago), licensed MIT. It adds 28 tokens to every session and 446 once invoked, about $0.0001 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.
