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 | $0.00499 | $0.00499 |
| Opus 5.5 | $0.00200 | $0.00200 |
| Sonnet 5.5 | $0.00100 | $0.00100 |
| Haiku 4.5 | $0.00050 | $0.00050 |
Grade A, and why
CiteCheck AGENTS.md 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 2mo 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.

CiteCheck — Development & Testing Rules
Pre-Push Testing Requirement
Every feature change MUST be validated against the demo test fixtures before committing.
The latex_paper/ directory (sibling to CiteCheck/) contains intentionally flawed references used as the canonical integration test:
# From inside CiteCheck/
cd CiteCheck
# 1. Test LaTeX source parsing
citecheck ../latex_paper/main.tex --skip-verification --skip-semantic -o /tmp/test_latex.md
# Expected baseline:
# - 19 references parsed
# - 18 citation markers detected
# - 7 format issues (preprints, wrong entry type, missing author, future year)
# - Uncited list: only [3] touvron2023llama
# 2. Test PDF fallback parsing
citecheck ../latex_paper/main.pdf --skip-verification --skip-semantic -o /tmp/test_pdf.md
# Expected baseline:
# - 18 references parsed (PDF loses incomplete entry metadata)
# - 18 citation markers detected
# - 0 format issues (PDF parser has limited format checking)
Regression Checklist
- LaTeX test produces expected reference count (±0)
- LaTeX test produces expected citation marker count (±0)
- Uncited references list shows ONLY truly uncited entries (e.g.,
touvron2023llama) - PDF test runs without crashing
- pytest
tests/test_parser.pypasses (8/8) -
python -m citecheck --helpworks
Known Improvements (Post-0.1.0)
- arXiv year parsing (
pdf_parser.py): arXiv IDs likearXiv:2004.05150are no longer mistaken for publication years. - Crossref false-match filtering (
verifier.py): Low-similarity matches are now rejected; large year mismatches (>2 years) are flagged separately from small mismatches.
If any baseline metric shifts unexpectedly, investigate before pushing.
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 AGENTS.md is an instructions file published in the GitHub repository color4-alt/CiteCheck (70 stars, last pushed 5mo ago), licensed MIT. It adds 499 tokens to every session, about $0.0020 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 2026-08-30.
