dslop

Detect AI writing patterns (slop) in your codebase.

dslop is a fast CLI linter for prose. It flags telltale LLM writing patterns (em-dashes, double-hyphen dashes, "it's not X, it's Y" constructions) and statistical tells (uniform sentence rhythm, flat word-frequency distributions) that human writing rarely produces.

Install

pip install dslop
# or
uvx dslop .

Use

dslop                       # check current directory
dslop README.md docs/       # check specific paths
dslop --config dslop.toml   # use a specific config

# Read from stdin:
echo "It's not a tool — it's a platform." | dslop -
pbpaste | dslop                                         # clipboard
git show HEAD:README.md | dslop                         # a past revision

Exits non-zero on violations, so it drops into CI or pre-commit unchanged.

Configure

Create dslop.toml at your repo root:

[metrics]
sentence-length-cv = 0.3
sentence-length-kurtosis = 1.5

[metrics.word-freq-dispersion]
threshold = 0.6
chunk-size = 200
top-n = 20

Each metric accepts a threshold (f64) or false to disable.
