Workflow

Step 1: Read the bibliography

Read docs/overleaf/refs.bib and extract all citation keys.

Step 2: Scan all files for citation keys

• .tex files in docs/overleaf/: look for \textcite{, \parencite{, \cite{, \citet{, \citep{, \citeauthor{, \citeyear{}
• .qmd files in book/: look for @key, [@key], [@key1; @key2]
• Extract all unique citation keys used

Step 3: Cross-reference

• Missing entries (CRITICAL): Citations used in files but NOT in refs.bib
• Unused entries (informational): Entries in refs.bib not cited anywhere
• Potential typos: Similar-but-not-matching keys (Levenshtein distance)

Step 4: Check entry quality

For each bib entry:

• Required fields present (author, title, year, journal/booktitle)
• Author field properly formatted (Last, First and Last, First)
• Year is reasonable (1900-2026)
• No malformed characters or encoding issues
• Entry type appropriate (@article, @incollection, @techreport, etc.)

Step 5: Report findings
