Diff Exclusion Patterns

ACR_DIFF_EXCLUDE_GLOBS filters files from the diff sent to the LLM while still committing them. This reduces noise and token usage for binary, generated, or data files. Default patterns:

*.json, *.xml, *.csv, *.pdf, *.lock, *.svg, *.png, *.jpg, *.jpeg, *.gif, *.ico, *.woff, *.woff2, *.ttf, *.eot, *.min.js, *.min.css

Override with a comma-separated list:

export ACR_DIFF_EXCLUDE_GLOBS="*.lock,*.svg,package-lock.json"

For a single run, adjust the effective filter without touching your config:

cgen --diff-include "*.xml"   # send .xml files to the LLM even though they're excluded
cgen --diff-exclude "*.sql"   # additionally drop .sql files from the LLM diff

--diff-include wins over any exclude pattern (allow-over-deny). Patterns with a slash match repository-relative paths; basename patterns such as *.lock match at any depth. Invalid patterns and filters that remove every changed file are errors. The same filters apply to normal generation and cgen alter.

Excluded files are still committed — the patterns only control what the LLM sees. To keep files out of the commit itself, don't stage them.
