# Audit Citations and References
Cross-check all citation keys in the manuscript against `references.bib` and report mismatches.
## Steps
1. Read `index.qmd` and extract every citation key:
- Narrative citations: `@key`
- Parenthetical citations: `[@key]`, `[@key1; @key2]`
- Ignore email addresses and `@sec-`, `@fig-`, `@tbl-` cross-references
2. Read `references.bib` and extract every entry key (the identifier after `@article{`, `@book{`, etc.)
3. Check for duplicate keys within `references.bib` (same key defined more than once)
4. Report three categories:
**Errors — cited in manuscript but missing from `.bib`:**
- List each missing key with the line number in `index.qmd` where it appears
- For each, suggest running `/project:cite <key>` to add the entry
**Orphaned — in `.bib` but never cited in manuscript:**
- List each unused key (informational, not necessarily a problem)
**Duplicates — same key appears multiple times in `.bib`:**
- List each duplicate with line numbers in `references.bib`
5. Print a summary: total cited keys, total `.bib` entries, errors, orphaned, duplicates
## Error handling
- If `references.bib` does not exist, report the error and stop.
- If `index.qmd` contains no citations, report "No citations found" and stop.
