One-shot anomaly detection on the command line

Give jevotron a file and a little guidance. Get field-level anomaly scores, a focused review queue, and a cache that makes the next run cheaper.

Run your first scan Explore the commands Install agent skills

jevotron / airports.csv
$ jevotron scan airports.csv --guidance "Check airport locations."

First, set your API key

Get a key from the TypeSafe dashboard and set it in your shell:

export TYPESAFE_API_KEY="your-api-key"

02 / SCAN

Assess every entry

Jev scores selected fields together. Each entry gets the same guidance and optional examples.

Choose your fields →

03 / REVIEW

Start with the warnings

Sort suspicious entries, export CSV, or pipe JSONL into your existing shell workflow.

Build a review queue →

Small setup. Useful defaults.

CSV, YAML, JSON, TOML, text, OBO, and more work out of the box, including gzip files. The format reference covers defaults and format-specific options. Select fields with --field, add a sentence with --guidance, and run. Longer instructions can come from --guidance-file. A local Python config is available when a project needs custom parsing or reusable settings.

Unchanged input reuses its assessment. SQLite saves each successful result as it arrives. Reorder a file, change a reporting threshold, or resume a failed run without reassessing unchanged entries.

A review aid with visible evidence. Reports retain each field's probabilities, the entry score, source location, and assessment date. The warning score is the highest field anomaly probability; you choose the threshold.
