What is CiteCheck CLAUDE.md?

Project instructions for CiteCheck, a Python command-line tool and coding-agent skill for checking citations in academic papers.

Use them when working on citation parsing, PDF or BibTeX handling, source verification, thematic matching, or report generation in the CiteCheck project.

They give the agent the repository layout, relevant components, and working context needed to change or troubleshoot the citation-checking system correctly.

Token cost

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	$0.00675	$0.00675
Opus 5.5	$0.00270	$0.00270
Sonnet 5.5	$0.00135	$0.00135
Haiku 4.5	$0.00068	$0.00068

Security

Grade A, and why

CiteCheck CLAUDE.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 — Project Context for Claude Code

CiteCheck is a Python CLI tool and agent skill for verifying academic paper citations. This repository contains both the installable Python package (pip install CiteCheck) and the agent skill definitions.

When This Context Applies

Load this context when working on:

The citecheck Python package (src/citecheck/)
The agent skill definitions (skills/, references/)
CLI behavior, parsing logic, or report generation
Bug fixes or feature additions to the citation verification pipeline

Architecture Decisions

LaTeX-first, PDF-fallback: .tex + .bib parsing is precise; PDF extraction is lossy
Skill vs CLI separation: The CLI handles parsing/format/querying; the agent (Claude) handles thematic/semantic evaluation using its own reasoning
Zero mandatory API keys: Crossref and Semantic Scholar are public APIs; LLM matching is optional (--api-key) or delegated to the agent
Models extracted to models.py: Prevents circular imports between parser.py, bibtex_parser.py, and pdf_parser.py

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.
