citation-verifier skillA
citation-verifier is agent-read markdown (skill) from khaledsaeed18/dotclaude: Audit every citation in a chapter, paper, or proposal against the .bib file and the real world: each cite key must exist, each entry must resolve to a live DOI or arXiv record whose title, authors, and year match, and each claim attributed to a source must be supported by that source's note or text. Reports unverified, mismatched, and unsupported citations with the fix. Use before sending a draft to a supervisor, before submission, or whenever text was drafted with AI assistance and a fabricated.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
A fabricated or misattributed citation is the one error a thesis cannot survive. This skill treats every citation as unverified until three checks pass: the key exists, the entry is real, and the claim is supported.
## Level 1: every key exists
1. Extract cite keys from the document:
- LaTeX: `\cite{a,b}`, `\citep`, `\citet`, `\parencite`, `\textcite`, `\autocite`, `\footcite`, and starred/optional-argument forms.
- Markdown/Pandoc: `[@key]`, `[@a; @b, p. 3]`, `@key`.
- Word: extract with `pandoc file.docx -t markdown` and look for Zotero fields or `(Author, Year)` strings; match those against `.bib` `author`+`year`.
2. Parse the `.bib` keys (`^@\w+\{([^,]+),`).
3. Report keys cited but not defined (hard error) and entries defined but never cited (informational; the bibliography should usually contain only cited works).
## Level 2: every entry is real
For each cited entry:
1. If it has a `doi`: `curl -s "https://api.crossref.org/works/<doi>"` and compare title (normalised), first author surname, and year. A DOI that returns 404 is fabricated or mistyped: search CrossRef by title to find the real one and report both.

How to install
mdr add khaledsaeed18/dotclaude/citation-verifier@git:20260921.3cfc2b3mdr add khaledsaeed18/dotclaude/citation-verifier@sha256:bbca6a4d848b43e3Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
